Mainland, Orkney
–
The Mainland is the main island of Orkney, Scotland. Both of Orkneys burghs, Kirkwall and Stromness, lie on the island, seventy-five per cent of Orkneys population live on the island, which is more densely populated than the other islands of the archipelago. The lengthy history of the occupation has provided numerous important archaeological sites. There is an abundance of wildlife, especially seabirds, the name Mainland is a corruption of the Old Norse Meginland. Formerly the island was known as Hrossey meaning Horse Island. The island is densely populated and has much fertile farmland. The bulk of the Mainland is west of Kirkwall and is low-lying, with coastal cliffs to the north and west, the eastern part of the Mainland is shaped like the letter W, the easternmost peninsula being known as Deerness. To the south, causeways called Churchill Barriers connect the island to Burray and South Ronaldsay via Lamb Holm, Mainland effectively provides the core of the Orkney Islands, linking the northern members of the archipelago with the southern ones. At the east, and west ends, islands proceed to the north and south, the western part of the island is part of the Hoy and West Mainland National Scenic Area, one of 40 in Scotland. The population in 2011 was recorded as 17,162, an increase of just over 12% on the 2001 population of 15,315, there are 13 parishes on the island. Sandwick, Birsay and Stromness lie on the west coast, Rendall, Holm, Deerness and St Andrews are located to the east of central St Ola, which contains Kirkwall town. Firth, Orphir, Stenness and Harray lie west of Kirkwall, Harray has the unique distinction of being the only landlocked parish in Orkney, although it too has a significant coast along the Loch of Harray, albeit a freshwater one. The three main settlements on Mainland, in order of magnitude are Kirkwall and Stromness, both of which are burghs, and Finstown, Kirkwall has the seat of the Bishop of Orkney, and St. Magnus Cathedral is to be found there. It is also one of the ferry ports. Stromness A long-established seaport that grew with the expansion of whaling, the old town is clustered along the main street, flanked with houses and shops built from local stone, with narrow lanes and alleys branching off it. There is a link to Scrabster in Caithness on the Scottish mainland as well as the Isle of Hoy. Finstown Finstown is the third largest settlement, and used to be known as the Toon o Firth, the origin of its name is thought to be from an Irishman named David Phin who came to the area in 1811. It is on the direct Stromness to Kirkwall road, in common with most of the Orkney isles, Mainland rests almost entirely on a bedrock of Old Red Sandstone, which is about 400 million years old and was laid down in the Devonian period

Scotland
–
Scotland is a country that is part of the United Kingdom and covers the northern third of the island of Great Britain. It shares a border with England to the south, and is surrounded by the Atlantic Ocean, with the North Sea to the east. In addition to the mainland, the country is made up of more than 790 islands, including the Northern Isles, the Kingdom of Scotland emerged as an independent sovereign state in the Early Middle Ages and continued to exist until 1707. By inheritance in 1603, James VI, King of Scots, became King of England and King of Ireland, Scotland subsequently entered into a political union with the Kingdom of England on 1 May 1707 to create the new Kingdom of Great Britain. The union also created a new Parliament of Great Britain, which succeeded both the Parliament of Scotland and the Parliament of England. Within Scotland, the monarchy of the United Kingdom has continued to use a variety of styles, titles, the legal system within Scotland has also remained separate from those of England and Wales and Northern Ireland, Scotland constitutes a distinct jurisdiction in both public and private law. Glasgow, Scotlands largest city, was one of the worlds leading industrial cities. Other major urban areas are Aberdeen and Dundee, Scottish waters consist of a large sector of the North Atlantic and the North Sea, containing the largest oil reserves in the European Union. This has given Aberdeen, the third-largest city in Scotland, the title of Europes oil capital, following a referendum in 1997, a Scottish Parliament was re-established, in the form of a devolved unicameral legislature comprising 129 members, having authority over many areas of domestic policy. Scotland is represented in the UK Parliament by 59 MPs and in the European Parliament by 6 MEPs, Scotland is also a member nation of the British–Irish Council, and the British–Irish Parliamentary Assembly. Scotland comes from Scoti, the Latin name for the Gaels, the Late Latin word Scotia was initially used to refer to Ireland. By the 11th century at the latest, Scotia was being used to refer to Scotland north of the River Forth, alongside Albania or Albany, the use of the words Scots and Scotland to encompass all of what is now Scotland became common in the Late Middle Ages. Repeated glaciations, which covered the land mass of modern Scotland. It is believed the first post-glacial groups of hunter-gatherers arrived in Scotland around 12,800 years ago, the groups of settlers began building the first known permanent houses on Scottish soil around 9,500 years ago, and the first villages around 6,000 years ago. The well-preserved village of Skara Brae on the mainland of Orkney dates from this period and it contains the remains of an early Bronze Age ruler laid out on white quartz pebbles and birch bark. It was also discovered for the first time that early Bronze Age people placed flowers in their graves, in the winter of 1850, a severe storm hit Scotland, causing widespread damage and over 200 deaths. In the Bay of Skaill, the storm stripped the earth from a large irregular knoll, when the storm cleared, local villagers found the outline of a village, consisting of a number of small houses without roofs. William Watt of Skaill, the laird, began an amateur excavation of the site, but after uncovering four houses

Neolithic
–
It ended when metal tools became widespread. The Neolithic is a progression of behavioral and cultural characteristics and changes, including the use of wild and domestic crops, the beginning of the Neolithic culture is considered to be in the Levant about 10, 200–8800 BC. It developed directly from the Epipaleolithic Natufian culture in the region, whose people pioneered the use of wild cereals, which then evolved into true farming. The Natufian period was between 12,000 and 10,200 BC, and the so-called proto-Neolithic is now included in the Pre-Pottery Neolithic between 10,200 and 8800 BC. By 10, 200–8800 BC, farming communities arose in the Levant and spread to Asia Minor, North Africa, Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BC. Early Neolithic farming was limited to a range of plants, both wild and domesticated, which included einkorn wheat, millet and spelt, and the keeping of dogs, sheep. By about 6900–6400 BC, it included domesticated cattle and pigs, the establishment of permanently or seasonally inhabited settlements, not all of these cultural elements characteristic of the Neolithic appeared everywhere in the same order, the earliest farming societies in the Near East did not use pottery. Early Japanese societies and other East Asian cultures used pottery before developing agriculture, unlike the Paleolithic, when more than one human species existed, only one human species reached the Neolithic. The term Neolithic derives from the Greek νέος néos, new and λίθος líthos, stone, the term was invented by Sir John Lubbock in 1865 as a refinement of the three-age system. In the Middle East, cultures identified as Neolithic began appearing in the 10th millennium BC, early development occurred in the Levant and from there spread eastwards and westwards. Neolithic cultures are attested in southeastern Anatolia and northern Mesopotamia by around 8000 BC. The total excavated area is more than 1,200 square yards, the Neolithic 1 period began roughly 10,000 years ago in the Levant. A temple area in southeastern Turkey at Göbekli Tepe dated around 9500 BC may be regarded as the beginning of the period. This site was developed by nomadic tribes, evidenced by the lack of permanent housing in the vicinity. At least seven stone circles, covering 25 acres, contain limestone pillars carved with animals, insects, Stone tools were used by perhaps as many as hundreds of people to create the pillars, which might have supported roofs. Other early PPNA sites dating to around 9500–9000 BC have been found in Jericho, Israel, Gilgal in the Jordan Valley, the start of Neolithic 1 overlaps the Tahunian and Heavy Neolithic periods to some degree. The major advance of Neolithic 1 was true farming, in the proto-Neolithic Natufian cultures, wild cereals were harvested, and perhaps early seed selection and re-seeding occurred. The grain was ground into flour, emmer wheat was domesticated, and animals were herded and domesticated

Historic Scotland
–
Historic Scotland was an executive agency of the Scottish Government from 1991 to 2015, responsible for safeguarding Scotlands built heritage, and promoting its understanding and enjoyment. Under the terms of a Bill of the Scottish Parliament published on 3 March 2014, Historic Scotland was dissolved, HES also took over the functions of the Royal Commission on the Ancient and Historical Monuments of Scotland. Historic Scotland was an organisation to the Ancient Monuments Division of the Ministry of Works. It was created as an agency in 1991 and was attached to the Scottish Executive Education Department, as part of the Scottish Government, Historic Scotland was directly accountable to the Scottish Ministers. In 2002, proposals to restore Castle Tioram in the West Highlands, by putting a roof back on, were blocked by Historic Scotland and this position was supported in an extensive local Public Inquiry at which the arguments for both sides were heard. It has been implied that this dispute has led to a review of the operations of the organisation, after widespread consultation, Historic Scotland published a comprehensive series of Scottish Historic Environment Policy papers, consolidated into a single volume in October 2008. The agencys Framework Document set out the responsibilities of the Scottish Ministers and its Corporate Plan sets out its targets and performance against them. Historic Scotland had direct responsibility for maintaining and running over 360 monuments in its care, about a quarter of which are manned and these properties have additional features such as guidebooks, books and other resources. Historic Scotland sought to increase the number of run at its sites. Similarly, new museums and visitor centres were opened, notably at Arbroath Abbey, there was also a hospitality section, which makes some properties available for wedding receptions and other functions. Lifetime memberships were also available, and all received a quarterly magazine Historic Scotland. Royal Commission on the Ancient and Historical Monuments of Scotland Scottish Ten Official website

World Heritage Site
–
A World Heritage Site is a landmark which has been officially recognized by the United Nations, specifically by the United Nations Educational, Scientific and Cultural Organization. Sites are selected on the basis of having cultural, historical, scientific or some form of significance. UNESCO regards these sites as being important to the interests of humanity. The programme catalogues, names, and conserves sites of outstanding cultural or natural importance to the common culture, under certain conditions, listed sites can obtain funds from the World Heritage Fund. The program was founded with the Convention Concerning the Protection of the Worlds Cultural and Natural Heritage, since then,192 state parties have ratified the convention, making it one of the most adhered to international instruments. As of July 2016,1052 sites are listed,814 cultural,203 natural, in 1959, the governments of Egypt and Sudan requested UNESCO to assist their countries to protect and rescue the endangered monuments and sites. In 1960, the Director-General of UNESCO launched an appeal to the Member States for an International Campaign to Save the Monuments of Nubia, the campaign, which ended in 1980, was considered a success. The project cost $80 million, about $40 million of which was collected from 50 countries, the projects success led to other safeguarding campaigns, saving Venice and its lagoon in Italy, the ruins of Mohenjo-daro in Pakistan, and the Borobodur Temple Compounds in Indonesia. UNESCO then initiated, with the International Council on Monuments and Sites, the United States initiated the idea of cultural conservation with nature conservation. The International Union for Conservation of Nature developed similar proposals in 1968, the Convention came into force on 17 December 1975. As of June 2016, it has been ratified by 192 states, including 188 UN member states plus the Cook Islands, the Holy See, Niue, a country must first list its significant cultural and natural sites, the result is called the Tentative List. A country may not nominate sites that have not been first included on the Tentative List, next, it can place sites selected from that list into a Nomination File. The Nomination File is evaluated by the International Council on Monuments and Sites and these bodies then make their recommendations to the World Heritage Committee. There are ten selection criteria – a site must meet at least one of them to be included on the list, up to 2004, there were six criteria for cultural heritage and four criteria for natural heritage. In 2005, this was modified so there is now only one set of ten criteria. Nominated sites must be of outstanding value and meet at least one of the ten criteria. Thus, the Geneva Convention treaty promulgates, Article 53, PROTECTION OF CULTURAL OBJECTS AND OF PLACES OF WORSHIP. There are 1,052 World Heritage Sites located in 165 States Party, of these,814 are cultural,203 are natural and 35 are mixed properties

Heart of Neolithic Orkney
–
Heart of Neolithic Orkney refers to a group of Neolithic monuments found on the Mainland, one of the islands of Orkney, Scotland. The name was adopted by UNESCO when it proclaimed these sites as a World Heritage Site in 1999, the site of patrimony currently consists of four sites, Maeshowe – a unique chambered cairn and passage grave, aligned so that its central chamber is illuminated on the winter solstice. It was looted by Vikings who left one of the largest collections of inscriptions in the world. Standing Stones of Stenness – the four remaining megaliths of a henge, ring of Brodgar – a stone circle 104 metres in diameter, originally composed of 60 stones set within a circular ditch up to 3 metres deep and 10 metres wide, forming a henge monument. It has been estimated that the structure took 80,000 man-hours to construct, skara Brae – a cluster of eight houses making up Northern Europe’s best-preserved Neolithic village. Although it is not part of the World Heritage Site, the Ness of Brodgar contribute greatly to our understanding of the WHS according to Historic Scotland, prehistoric Scotland Timeline of prehistoric Scotland Oldest buildings in Scotland Oldest buildings in the world

Orkney
–
Orkney /ˈɔːrkni/, also known as the Orkney Islands, is an archipelago in the Northern Isles of Scotland, situated off the north coast of Great Britain. Orkney is 16 kilometres north of the coast of Caithness and comprises approximately 70 islands, the largest island Mainland is often referred to as the Mainland. It has an area of 523 square kilometres, making it the sixth-largest Scottish island, the largest settlement and administrative centre is Kirkwall. A form of the dates to the pre-Roman era and the islands have been inhabited for at least 8500 years, originally occupied by Mesolithic and Neolithic tribes. Orkney was invaded and forcibly annexed by Norway in 875 and settled by the Norse, the Scottish Parliament then re-annexed the earldom to the Scottish Crown in 1472, following the failed payment of a dowry for James IIIs bride Margaret of Denmark. Orkney contains some of the oldest and best-preserved Neolithic sites in Europe, Orkney is one of the 32 council areas of Scotland, a constituency of the Scottish Parliament, a lieutenancy area, and a historic county. The local council is Orkney Islands Council, one of only three Councils in Scotland with a majority of elected members who are independents. In addition to the Mainland, most of the islands are in two groups, the North and South Isles, all of which have a geological base of Old Red Sandstone. The climate is mild and the soils are fertile, most of the land being farmed. Agriculture is the most important sector of the economy, the significant wind and marine energy resources are of growing importance, and the island generates more than its total yearly electricity demand using renewables. The local people are known as Orcadians and have a distinctive Orcadian dialect of Scots, there is an abundance of marine and avian wildlife. Pytheas of Massilia visited Britain – probably sometime between 322 and 285 BC – and described it as triangular in shape, with a northern tip called Orcas and this may have referred to Dunnet Head, from which Orkney is visible. Speakers of Old Irish referred to the islands as Insi Orc island of the pigs, the archipelago is known as Ynysoedd Erch in modern Welsh and Arcaibh in modern Scottish Gaelic, the -aibh representing a fossilized prepositional case ending. The Anglo-Saxon monk Bede refers to the islands as Orcades insulae in his seminal work Ecclesiastical History of the English People. Norwegian settlers arriving from the ninth century reinterpreted orc as the Old Norse orkn seal. The plural suffix -jar was later removed in English leaving the modern name Orkney, according to the Historia Norwegiæ, Orkney was named after an earl called Orkan. The Norse knew Mainland Orkney as Megenland Mainland or as Hrossey Horse Island, the island is sometimes referred to as Pomona, a name that stems from a sixteenth-century mistranslation by George Buchanan, which has rarely been used locally. A charred hazelnut shell, recovered in 2007 during excavations in Tankerness on the Mainland has been dated to 6820–6660 BC indicating the presence of Mesolithic nomadic tribes

UNESCO
–
The United Nations Educational, Scientific and Cultural Organization is a specialized agency of the United Nations based in Paris. It is the heir of the League of Nations International Committee on Intellectual Cooperation, UNESCO has 195 member states and nine associate members. Most of its offices are cluster offices covering three or more countries, national and regional offices also exist. UNESCO pursues its objectives through five major programs, education, natural sciences, social/human sciences, culture and it is also a member of the United Nations Development Group. UNESCO and its mandate for international cooperation can be traced back to a League of Nations resolution on 21 September 1921, on 18 December 1925, the International Bureau of Education began work as a non-governmental organization in the service of international educational development. However, the work of predecessor organizations was largely interrupted by the onset of World War II. On 30 October 1943, the necessity for an organization was expressed in the Moscow Declaration, agreed upon by China, the United Kingdom, the United States. This was followed by the Dumbarton Oaks Conference proposals of 9 October 1944, a prominent figure in the initiative for UNESCO was Rab Butler, the Minister of Education for the United Kingdom. At the ECO/CONF, the Constitution of UNESCO was introduced and signed by 37 countries, the Preparatory Commission operated between 16 November 1945, and 4 November 1946—the date when UNESCOs Constitution came into force with the deposit of the twentieth ratification by a member state. The first General Conference took place between 19 November to 10 December 1946, and elected Dr. Julian Huxley to Director-General and this change in governance distinguished UNESCO from its predecessor, the CICI, in how member states would work together in the organizations fields of competence. In 1956, the Republic of South Africa withdrew from UNESCO claiming that some of the organizations publications amounted to interference in the racial problems. South Africa rejoined the organization in 1994 under the leadership of Nelson Mandela, UNESCOs early work in the field of education included the pilot project on fundamental education in the Marbial Valley, Haiti, started in 1947. This project was followed by missions to other countries, including, for example. In 1948, UNESCO recommended that Member States should make free primary education compulsory, in 1990, the World Conference on Education for All, in Jomtien, Thailand, launched a global movement to provide basic education for all children, youths and adults. Ten years later, the 2000 World Education Forum held in Dakar, Senegal, UNESCOs early activities in culture included, for example, the Nubia Campaign, launched in 1960. The purpose of the campaign was to move the Great Temple of Abu Simbel to keep it from being swamped by the Nile after construction of the Aswan Dam, during the 20-year campaign,22 monuments and architectural complexes were relocated. This was the first and largest in a series of campaigns including Mohenjo-daro, Fes, Kathmandu, Borobudur, the organizations work on heritage led to the adoption, in 1972, of the Convention concerning the Protection of the World Cultural and Natural Heritage. The World Heritage Committee was established in 1976 and the first sites inscribed on the World Heritage List in 1978, since then important legal instruments on cultural heritage and diversity have been adopted by UNESCO member states in 2003 and 2005

Stonehenge
–
Stonehenge is a prehistoric monument in Wiltshire, England,2 miles west of Amesbury and 8 miles north of Salisbury. Stonehenge consists of ring of standing stones, with each standing stone around 4.1 metres high,2.1 metres wide and weighing around 25 tons. The stones are set within earthworks in the middle of the most dense complex of Neolithic and Bronze Age monuments in England, archaeologists believe it was constructed from 3000 BC to 2000 BC. The surrounding circular earth bank and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC. Radiocarbon dating suggests that the first bluestones were raised between 2400 and 2200 BC, although they may have been at the site as early as 3000 BC, one of the most famous landmarks in the UK, Stonehenge is regarded as a British cultural icon. It has been a legally protected Scheduled Ancient Monument since 1882 when legislation to protect historic monuments was first successfully introduced in Britain, the site and its surroundings were added to UNESCOs list of World Heritage Sites in 1986. Stonehenge is owned by the Crown and managed by English Heritage, Stonehenge could have been a burial ground from its earliest beginnings. Deposits containing human bone date from as early as 3000 BC, when the ditch and bank were first dug, William Stukeley in 1740 notes, Pendulous rocks are now called henges in Yorkshire. I doubt not, Stonehenge in Saxon signifies the hanging stones. Like Stonehenges trilithons, medieval gallows consisted of two uprights with a lintel joining them, rather than the inverted L-shape more familiar today, the henge portion has given its name to a class of monuments known as henges. Archaeologists define henges as earthworks consisting of a banked enclosure with an internal ditch. As often happens in archaeological terminology, this is a holdover from antiquarian use, Stonehenge evolved in several construction phases spanning at least 1500 years. There is evidence of construction on and around the monument that perhaps extends the landscapes time frame to 6500 years. The modern phasing most generally agreed to by archaeologists is detailed below, features mentioned in the text are numbered and shown on the plan, right. Archaeologists have found four, or possibly five, large Mesolithic postholes and these held pine posts around 0.75 metres in diameter, which were erected and eventually rotted in situ. Three of the posts were in an east-west alignment which may have had significance, no parallels are known from Britain at the time. A settlement that may have been contemporaneous with the posts has been found at Blick Mead, a reliable year round spring 1 mile from Stonehenge. Salisbury Plain was then still wooded but 4,000 years later, during the earlier Neolithic, people built an enclosure at Robin Hoods Ball. In approximately 3500 BC, a Stonehenge Cursus was built 700 metres north of the site as the first farmers began to clear the trees, a number of other adjacent stone and wooden structures and burial mounds, previously overlooked, may date as far back as 4000 BC

Great Pyramid of Giza
–
The Great Pyramid of Giza is the oldest and largest of the three pyramids in the Giza pyramid complex bordering what is now El Giza, Egypt. It is the oldest of the Seven Wonders of the Ancient World, initially at 146.5 metres, the Great Pyramid was the tallest man-made structure in the world for more than 3,800 years. Originally, the Great Pyramid was covered by casing stones that formed an outer surface. Some of the stones that once covered the structure can still be seen around the base. There have been varying scientific and alternative theories about the Great Pyramids construction techniques, most accepted construction hypotheses are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place. There are three chambers inside the Great Pyramid. The lowest chamber is cut into the bedrock upon which the pyramid was built and was unfinished, the so-called Queens Chamber and Kings Chamber are higher up within the pyramid structure. It is believed the pyramid was built as a tomb for Fourth Dynasty Egyptian pharaoh Khufu and was constructed over a 20-year period, Khufus vizier, Hemiunu, is believed by some to be the architect of the Great Pyramid. It is thought that, at construction, the Great Pyramid was originally 280 Egyptian cubits tall, each base side was 440 cubits,230.4 metres long. The mass of the pyramid is estimated at 5.9 million tonnes, the volume, including an internal hillock, is roughly 2,500,000 cubic metres. Based on these estimates, building the pyramid in 20 years would involve installing approximately 800 tonnes of stone every day, the first precision measurements of the pyramid were made by Egyptologist Sir Flinders Petrie in 1880–82 and published as The Pyramids and Temples of Gizeh. Almost all reports are based on his measurements, many of the casing stones and inner chamber blocks of the Great Pyramid fit together with extremely high precision. Based on measurements taken on the casing stones, the mean opening of the joints is only 0.5 millimetre wide. The pyramid remained the tallest man-made structure in the world for over 3,800 years, the accuracy of the pyramids workmanship is such that the four sides of the base have an average error of only 58 millimetres in length. The base is horizontal and flat to within ±15 mm, the ratio of the perimeter to height of 1760/280 royal cubits equates to 2π to an accuracy of better than 0. 05%. Some Egyptologists consider this to have been the result of deliberate design proportion, verner wrote, We can conclude that although the ancient Egyptians could not precisely define the value of π, in practice they used it. Petrie, author of Pyramids and Temples of Gizeh concluded, but these relations of areas, others have argued that the Ancient Egyptians had no concept of pi and would not have thought to encode it in their monuments. They believe that the observed pyramid slope may be based on a simple seked slope choice alone, with no regard to the overall size, in 2013 rolls of papyrus were discovered written by some of those who delivered stone and other construction materials to Khufus brother at Giza

Pompeii
–
Pompeii was an ancient Roman town-city near modern Naples, in the Campania region of Italy, in the territory of the comune of Pompei. Pompeii, along with Herculaneum and many villas in the area, was mostly destroyed and buried under 4 to 6 m of volcanic ash. Researchers believe that the town was founded in the seventh or sixth century BC by the Osci or Oscans. It came under the domination of Rome in the 4th century BC, by the time of its destruction,160 years later, its population was estimated at 11,000 people, and the city had a complex water system, an amphitheatre, gymnasium, and a port. The eruption destroyed the city, killing its inhabitants and burying it under tons of ash, the site was lost for about 1,500 years until its initial rediscovery in 1599 and broader rediscovery almost 150 years later by Spanish engineer Rocque Joaquin de Alcubierre in 1748. The objects that lay beneath the city have been preserved for centuries because of the lack of air and these artefacts provide an extraordinarily detailed insight into the life of a city during the Pax Romana. During the excavation, plaster was used to fill in the voids in the ash layers that once held human bodies and this allowed archaeologists to see the exact position the person was in when he or she died. Pompeii has been a tourist destination for over 250 years, today it has UNESCO World Heritage Site status and is one of the most popular tourist attractions in Italy, with approximately 2.5 million visitors every year. Pompeii in Latin is a second declension plural, the ruins of Pompeii are located near the modern suburban town of Pompei. It stands on a formed by a lava flow to the north of the mouth of the Sarno River. Today it is some distance inland, but in ancient times was nearer to the coast, Pompeii is about 8 km away from Mount Vesuvius. It covered a total of 64 to 67 hectares and was home to approximately 11,000 to 11,500 people on the basis of household counts and it was a major city in the region of Campania. Three sheets of sediment have been found on top of the lava that lies below the city and, mixed in with the sediment, archaeologists have found bits of bone, pottery shards. Carbon dating has placed the oldest of these layers from the 8th–6th centuries BC, the other two strata are separated either by well-developed soil layers or Roman pavement, and were laid in the 4th century BC and 2nd century BC. It is theorized that the layers of the sediment were created by large landslides. The town was founded around the 7th-6th century BC by the Osci or Oscans and it had already been used as a safe port by Greek and Phoenician sailors. According to Strabo, Pompeii was also captured by the Etruscans, and in recent excavations have shown the presence of Etruscan inscriptions. Pompeii was captured for the first time by the Greek colony of Cumae, allied with Syracuse, in the 5th century BC, the Samnites conquered it, the new rulers imposed their architecture and enlarged the town

Hillock
–
A hillock or knoll is a small hill, usually separated from a larger group of hills such as a range. Hillocks are similar in their distribution and size to small mesas or buttes, the term is largely a British one. This particular formation occurs often in Great Britain and China, one of the most famous knolls is the one near John F. Kennedys point of assassination, the Grassy Knoll. A Blind Knoll is either hidden or not readily apparent to those driving vehicles, there are road signs that warn of this, advising drivers to slow down

Laird
–
Laird is a generic name for the owner of a large, long-named Scottish estate, roughly equivalent to an esquire in England, yet ranking above the same in Scotland. In the Scottish order of precedence, a laird ranks below a baron and this rank is only held by those lairds holding official recognition in a territorial designation by the Lord Lyon King of Arms. They are usually styled of, and are entitled to place The Much Honoured before their name. g. THE HOLDER IS THE LORD OF THE MANOR/LAIRD OF and it is a description rather than a title, and is not appropriate for the owner of a normal residential property, far less the owner of a small souvenir plot of land. It goes without saying that the term ‘laird’ is not synonymous with that of ‘lord’ or ‘lady’, ownership of a souvenir plot of land is not sufficient to bring a person otherwise ineligible within the jurisdiction of the Lord Lyon for the purpose of seeking a Grant of Arms. Historically, the bonnet laird was applied to rural, petty landowners. Bonnet lairds filled a position in society below lairds and above husbandmen, the word laird is known to have been used from the 15th century, and is a shortened form of laverd, derived from the Old English word hlafweard meaning warden of loaves. In the 15th and 16th centuries, the designation was used for land owners holding directly of the Crown, lairds reigned over their estates like princes, their castles forming a small court. Originally in the 16th and 17th centuries, the designation was applied to the chief of a highland clan. The laird may possess certain local or feudal rights, a certain level of landownership was a necessary qualification. A laird is said to hold a lairdship, a woman who holds a lairdship in her own right has been styled with the honorific Lady. Although laird is sometimes translated as lord and historically signifies the same, the designation is a corporeal hereditament, i. e. the designation cannot be held in gross, and cannot be bought and sold without selling the physical land. A laird possessing a Coat of Arms registered in the Public Register of All Arms, several websites, and internet vendors on websites like Ebay, sell Scottish lairdships along with small plots of land. They see their contract purporting to sell a plot of Scottish souvenir land as bestowing them the right to the title Laird. This is despite the fact that the buyer does not acquire ownership of the plot because registration of the plot is prohibited by Land Registration Act 2012, s 22. While tolerating public access, he feels threatened by new legislation, traditionally, a laird is formally styled in the manner evident on the 1730 tombstone in a Scottish churchyard. It reads, The Much Honoured Laird of, the section titled Scottish Feudal Baronies in Debretts states that the use of the prefix The Much Hon. is correct, but that most lairds prefer the unadorned name and territorial designation. By the early 20th century, the wife came to adopt her husbands full surname

University of Edinburgh
–
The University of Edinburgh, founded in 1582, is the sixth oldest university in the English-speaking world and one of Scotlands ancient universities. The university is deeply embedded in the fabric of the city of Edinburgh, the University of Edinburgh was ranked 17th and 21st in the world by the 2014–15 and 2015-16 QS rankings. It is now ranked 19th in the according to 2016-17 QS Rankings. It is ranked 16th in the world in arts and humanities by the 2015–16 Times Higher Education Ranking and it is ranked the 23rd most employable university in the world by the 2015 Global Employability University Ranking. It is ranked as the 6th best university in Europe by the U. S. News Best Global Universities Ranking and it is a member of both the Russell Group, and the League of European Research Universities, a consortium of 21 research universities in Europe. It has the third largest endowment of any university in the United Kingdom, after the universities of Cambridge and it continues to have links to the British Royal Family, having had the Duke of Edinburgh as its Chancellor from 1953 to 2010 and Princess Anne since 2011. Edinburgh receives approximately 50,000 applications every year, making it the fourth most popular university in the UK by volume of applicants, after St Andrews, it is the most difficult university to gain admission into in Scotland, and 9th overall in the UK. This was a move at the time, as most universities were established through Papal bulls. Established as the Tounis College, it opened its doors to students in October 1583, instruction began under the charge of another St Andrews graduate Robert Rollock. It was the fourth Scottish university in a period when the more populous. It was renamed King Jamess College in 1617, by the 18th century, the university was a leading centre of the Scottish Enlightenment. The universitys first custom-built building was the Old College, now Edinburgh Law School and its first forte in teaching was anatomy and the developing science of surgery, from which it expanded into many other subjects. From the basement of a nearby house ran the anatomy tunnel corridor and it went under what was then North College Street, and under the university buildings until it reached the universitys anatomy lecture theatre, delivering bodies for dissection. It was from this tunnel the body of William Burke was taken after he had been hanged, towards the end of the 19th century, Old College was becoming overcrowded and Robert Rowand Anderson was commissioned to design new Medical School premises in 1875. The medical school was more or less built to his design and was completed by the addition of the McEwan Hall in the 1880s. The building now known as New College was originally built as a Free Church college in the 1840s and has been the home of divinity at the university since the 1920s. The two oldest schools – law and divinity – are both well-esteemed, with law being based in Old College and divinity in New College on the Mound and they are also represented by the Edinburgh University Sports Union which was founded in 1866. The medical school is renowned throughout the world and it was widely considered the best medical school in the English-speaking world throughout the 18th century and first half of the 19th century

V. Gordon Childe
–
Vere Gordon Childe, better known as V. Gordon Childe, was an Australian archaeologist and philologist who specialized in the study of European prehistory. Here, he embraced the socialist movement and campaigned against the First World War, growing critical of Labor, he authored an analysis of their policies and joined the far-left Industrial Workers of the World. In doing so he introduced the continental European concept of a culture to the British archaeological community. From 1927 through to 1946 he worked as the Abercromby Professor of Archaeology at the University of Edinburgh, throughout, he continued to publish prolifically, producing excavation reports, journal articles, and books. With Stuart Piggott and Grahame Clark he co-founded The Prehistoric Society in 1934, remaining committed to his socialist ideals, he embraced Marxism, and used Marxist ideas as an interpretative framework for archaeological data. He also became a sympathiser with the Soviet Union and visited the country on a number of occasions. His beliefs resulted in him being legally barred from entering the United States, upon retirement, he returned to Australias Blue Mountains, there committing suicide. Childe was born on 14 April 1892 in Sydney, New South Wales and he was the only surviving child of the Reverend Stephen Henry and Harriet Eliza Childe, a middle-class couple of English descent. Stephen Childe was a second-generation Anglican priest, ordained into the Church of England in 1867 after gaining a BA from the University of Cambridge, becoming a teacher, in 1871 he married Mary Ellen Latchford, together having five children. They moved to Australia in 1878 and it was here that Mary died, and in 1886 Stephen married Harriet, an Englishwoman from a wealthy background who had moved to Australia as a child. Gordon Childe was raised alongside five half-siblings at his fathers country house. Reverend Childe worked as the minister for St. Thomas Parish, a sickly child, Gordon Childe was educated at home for a number of years, before gaining a private school education in North Sydney. In 1907, he began attending Sydney Church of England Grammar School, gaining his Junior Matriculation in 1909, in July 1910 his mother died, his father soon took Monica Gardiner as his third wife. At university, he became a member of the Debating Society. Also while there, he became a friend of fellow undergraduate Herbert Vere Evatt. Ending his studies in 1913, Childe graduated the year with various honours and prizes. Wishing to continue his education, he gained a £200 Cooper Graduate Scholarship in Classics, allowing him to afford the fees at Queens College. He set sail for Britain aboard the SS Orsova in August 1914, at Queens, Childe was entered for a diploma in classical archaeology followed by a Literae Humaniores degree, although he never completed the former

Grooved ware
–
Grooved ware is the name given to a pottery style of the British Neolithic. Its manufacturers are sometimes known as the Grooved ware people, unlike the later Beaker ware, Grooved culture was not an import from the continent but seems to have developed in Orkney, early in the 3rd millennium BC, and was soon adopted in Britain and Ireland. The diagnostic shape for the style is a pot with straight sides sloping outwards. Beyond this the pottery comes in varieties, some with complex geometric decorations others with applique bands added. The latter has led archaeologists to argue that the style is a skeuomorph and is derived from wicker basketry. Grooved ware pots excavated at Balfarg in Fife have been analysed to determine their contents. It appears that some of the vessels there may have used to hold black henbane which is a poison. Since many Grooved ware pots have been found at henge sites and in burials, Grooved ware comes in many sizes, some vessels are extremely large, c.30 gallons, and would be suitable for fermentation. The majority are smaller, ranging from jug- to cup-size, the earliest examples have been found in Orkney and may have evolved from earlier Unstan ware bowls. The recent excavations at nearby Ness of Brodgar have revealed many sherds of finely decorated Grooved ware pottery, a large number of drinking vessels have also been identified. The style soon spread and it was used by the builders of the first phase of Stonehenge, Grooved ware pottery has been found in abundance in recent excavations at Durrington Walls and Marden Henge in Wiltshire. Here, the feasting would have involved drinking ale and eating pork, smaller quantities of Grooved ware have been found at the nearby site of Figsbury Ring. Grooved ware was previously referred to as Rinyo-Clacton ware, first identified by Stuart Piggott in the 1950s, rinyo is a neolithic settlement on the island of Rousay, Orkney. The site at Clacton now lies under the sea, one way the tradition may have spread is through trade routes up the west coast of Britain. What seems unusual is that although they shared the style of pottery. Evidence at some early Henges suggests that there were staging and trading points on a motorway during the Neolithic. This evidence perhaps explains how Cumbrian stone axes found their way to Orkney, Unstan ware, a variation on grooved ware, emerged in Orkney. The people who used Unstan ware had totally different burial practices, some hybrid chambered cairns have emerged in this region, containing architectural features of both the Maeshowe subclass and the Orkney-Cromarty stalled subclasses of cairn

Pottery
–
Pottery is the craft of making ceramic material into pots or potterywares using mud. Major types of potterywares include earthenware, stoneware and porcelain, the place where such wares are made by a potter is also called a pottery. Early Neolithic pottery have found in places such as Jomon Japan. A clay body can be decorated before or after firing, however, prior to shaping processes. Kneading helps to ensure an even moisture content throughout the body, air trapped within the clay body needs to be removed. This is called de-airing and can be accomplished either by a called a vacuum pug or manually by wedging. Wedging can also produce an even moisture content. Once a clay body has been kneaded and de-aired or wedged, after shaping, it is dried and then fired. Clay ware takes on varying physical characteristics during the making of pottery, at sufficient moisture content, bodies at this stage are in their most plastic form. Leather-hard refers to a body that has been dried partially. At this stage the clay object has approximately 15% moisture content, clay bodies at this stage are very firm and only slightly pliable. Trimming and handle attachment often occurs at the leather-hard state, bone-dry refers to clay bodies when they reach a moisture content at or near 0%. It is now ready to be bisque fired, bisque refers to the clay after the object is shaped to the desired form and fired in the kiln for the first time, known as bisque fired or biscuit fired. This firing changes the body in several ways. Mineral components of the body will undergo chemical changes that will change the colour of the clay. Glaze fired is the stage of some pottery making. A glaze may be applied to the form and the object can be decorated in several ways. After this the object is glazed fired, which causes the material to melt

Earth sheltering
–
Earth sheltering is the architectural practice of using earth against building walls for external thermal mass, to reduce heat loss, and to easily maintain a steady indoor air temperature. Earth sheltering has become more popular in modern times, especially among environmentalists and advocates of passive solar. However, the practice has been around for nearly as long as humans have been constructing their own shelters, the expression earth-sheltering is a generic term, with the general meaning, building design in which soil plays an integral part. An earth-bunded building is one where the significant element insulates one or more of the sheltered elevations of the building. The bunding can be partial or total, living within earth shelters has been a large part of human history. The connection to earth shelter dwellings began with the utilization of caves, today, earth shelter construction is a rare practice, especially in the U. S. A. However, progress has been slow, and earth shelter construction is often viewed by architects, engineers, techniques of earth sheltering have not yet become common knowledge, and much of society still remains unaware of the process or benefits of this type of building construction. Earth berming, Earth is piled up against exterior walls and packed, the roof may or may not be fully earth covered, and windows/openings may occur on one or more sides of the shelter. Due to the building being above ground, fewer moisture problems are associated with earth berming in comparison to underground/fully recessed construction, in-hill construction, The house is set into a slope or hillside. The most practical application is using a hill facing towards the equator, there is only one exposed wall in this type of earth sheltering, the wall facing out of the hill, all other walls are embedded within the earth/hill. Underground/fully recessed construction, The ground is excavated, and the house is set in below grade and it can also be referred to as an Atrium style due to the common atrium/courtyard constructed in the middle of the shelter to provide adequate light and ventilation. The benefits of earth sheltering are numerous, the Earths mass absorbs and retains heat. Over time, this heat is released to surrounding areas, such as an earth shelter, because of the high density of the earth, change in the earth’s temperature occurs slowly. This is known as ‘thermal lag. ’ Because of this principle, in most of the United States, the average temperature of the earth once below the frost line is between 55 and 57 degrees Fahrenheit. Frost line depths vary from region to region, in the USA frost lines can range from just under the surface to more than 40 inches. During the summer, the temperature gradient helps to cool the house, the reduction of air infiltration within an earth shelter can be highly profitable. Because three walls of the structure are surrounded by earth, very little surface area is exposed to the outside air. This alleviates the problem of air escaping the house through gaps around windows

Midden
–
The word is of Scandinavian via Middle English derivation, and is today used by archaeologists worldwide to describe any kind of feature containing waste products relating to day-to-day human life. They may be convenient, single-use pits created by groups or long-term. These features, therefore, provide a resource for archaeologists who wish to study the diet. Middens with damp, anaerobic conditions can even preserve organic remains in deposits as the debris of daily life are tossed on the pile, each individual toss will contribute a different mix of materials depending upon the activity associated with that particular toss. During the course of deposition sedimentary material is deposited as well, different mechanisms, from wind and water to animal digs, create a matrix which can also be analyzed to provide seasonal and climatic information. In some middens individual dumps of material can be discerned and analysed, a shell midden or shell mound is an archaeological feature consisting mainly of mollusk shells. The Danish term køkkenmøddinger was first used by Japetus Steenstrup to describe shell heaps, a midden, by definition, contains the debris of human activity, and should not be confused with wind or tide created beach mounds. Some shell middens are processing remains, areas where resources were processed directly after harvest. Some shell middens are directly associated with villages, as a designated village dump site, in other middens, the material is directly associated with a house in the village. Each household would dump its garbage directly outside the house, in all cases, shell middens are extremely complex and very difficult to excavate fully and exactly. The fact that they contain a record of what food was eaten or processed and many fragments of stone tools. Shells have a high carbonate content, which tends to make the middens alkaline. This slows the rate of decay caused by soil acidity. Shell middens were studied in Denmark in the half of the 19th century. The Danish word køkkenmødding is now used internationally, the English word midden derives from the same Old Norse word that produced the modern Danish one. Shell middens are found in coastal zones all over the world, consisting mostly of mollusc shells, they are interpreted as being the waste products of meals eaten by nomadic groups or hunting parties. Some are small examples relating to meals had by a handful of individuals, others are many metres in length and width, in Brazil, they are known as sambaquis, having been created over a long period between the 6th millennium BC and the beginning of European colonisation. On Canadas west coast, there are shell middens that run for more than a kilometer along the coast and are several meters deep, the midden in Namu, British Columbia is over 9 meters deep and spans over 10,000 years of continuous occupation

Peat
–
Peat, also called turf, is an accumulation of partially decayed vegetation or organic matter that is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem is the most efficient carbon sink on the planet because peatland plants capture the CO2 which is released from the peat. Sphagnum moss is one of the most common components in peat, soils that contain mostly peat are known as histosols. Peat forms in wetland conditions, where flooding obstructs flows of oxygen from the atmosphere, Peatlands, particularly bogs, are the most important source of peat. That said, other less common types, including fens, pocosins. Landscapes covered in peat are home to specific kinds of plants including Sphagnum moss, ericaceous shrubs, because organic matter accumulates over thousands of years, peat deposits also provide records of past vegetation and climates stored in plant remains like pollen. This allows humans to reconstruct past environments and study changes in land use. Peat is harvested as an important source of fuel in certain parts of the world, by volume, there are about 4 trillion cubic metres of peat in the world, covering a total of around 2% of the global land area, containing about 8 billion terajoules of energy. Over time, the formation of peat is often the first step in the formation of other fossil fuels such as coal. This is also the commonly used in the peat industry. At 106 g CO2/MJ, the carbon dioxide emission intensity of peat is higher than that of coal and natural gas, lastly, peat fires have been responsible for large public health disasters including the 1997 Southeast Asian haze. Peat forms when plant material does not fully decay in acidic and anaerobic conditions and it is composed mainly of wetland vegetation, principally bog plants including mosses, sedges, and shrubs. As it accumulates, the peat holds water and this slowly creates wetter conditions that allow the area of wetland to expand. Peatland features can include ponds, ridges, and raised bogs, most modern peat bogs formed 12,000 years ago in high latitudes after the glaciers retreated at the end of the last ice age. Peat usually accumulates slowly at the rate of about a millimetre per year, using Carbon-dating, scientists found that Peat in peatlands started forming 360 million years ago based on it currently containing 550 Gt of carbon. Peat material is either fibric, hemic, or sapric, fibric peats are the least decomposed and consist of intact fiber. Hemic peats are partially decomposed and sapric are the most decomposed, Phragmites peat is one composed of reed grass, Phragmites australis, and other grasses. It is denser than other types of peat

Driftwood
–
Driftwood is wood that has been washed onto a shore or beach of a sea, lake, or river by the action of winds, tides or waves. It is a form of debris or tidewrack. In some waterfront areas, driftwood is a major nuisance, however, the driftwood provides shelter and food for birds, fish and other aquatic species as it floats in the ocean. Gribbles, shipworms and bacteria decompose the wood and gradually turn it into nutrients that are reintroduced to the food web, sometimes, the partially decomposed wood washes ashore, where it also shelters birds, plants, and other species. Driftwood can become the foundation for sand dunes, most driftwood is the remains of trees, in whole or part, that have been washed into the ocean, due to flooding, high winds, or other natural occurrences, or as the result of logging. There is also a subset of driftwood known as drift lumber, erosion and wave action may make it difficult or impossible to determine the origin of a particular piece of driftwood. Driftwood can be used as part of furniture or other art forms. The EPA includes driftwood in its list of Items You Should Never Burn in Your Appliance, because it will release toxic chemicals when burned. According to Norse mythology, the first humans, Ask and Embla, were formed out of two pieces of driftwood, an ash and an elm, by the god Odin and his brothers, Vili, the Vikings would cast wood into the sea before making landfall. And the location of the wood would be an indication as to where to build their mead halls, the wood used would found the high-seat pillars of the new hall. Traditional Inuit boats such as the kayak were fashioned from driftwood frames covered in skins, wood that is burned today in these regions mainly consists of the remains of condemned wooden structures. Driftwood is still used as kindling by some, the Old Man of the Lake in Crater Lake, Oregon is a full-size tree that has been bobbing vertically in the lake for more than a century. Due to the water of the lake, the tree has been well preserved. Alice Gray, the legendary Diana of the Dunes, who fought to preserve the Indiana Dunes which contain quantities of driftwood named her college Driftwood, and made all her furniture from driftwood. Driftwood Sculptures are sculptures that are made of driftwood on beaches or mudflats, At Kullaberg, Sweden and this sculpture and two others led to the declaration of Ladonia as an independent nation. Sculptures were created on the Emeryville, California mudflat and marsh area of San Francisco Bay in the late 1960s. A driftwood sculpture was constructed in the Chapelle St Anne d Arles by the visitors to the exhibition Marcher dans le pas des glaneurs organized by A Flots perdus, the Ashden Awards for Sustainable Energy are sculpted out of driftwood. Artist Deborah Butterfield is known for her sculptures of horses, initially rendered from driftwood before being cast in bronze, artist Melanie Klaas is well known for her driftwood big game fish sculptures such as marlin and tuna as seen in Marlin magazine and Large woody debris

Seaweed
–
Seaweed refers to several species of macroscopic, multicellular, marine algae. The term includes some types of red, brown, and green algae, seaweed can also be classified by use. Seaweed is a term and lacks a formal definition. A seaweed may belong to one of groups of multicellular algae, the red algae, green algae. As these three groups do not have a common ancestor, the seaweed are in a polyphyletic group. In addition, some tuft-forming bluegreen algae are sometimes considered to be seaweed, seaweeds appearance somewhat resembles non-arboreal terrestrial plants. Two specific environmental requirements dominate seaweed ecology and these are the presence of seawater and the presence of light sufficient to drive photosynthesis. Another common requirement is an attachment point, although some genera such as Sargassum. As a result, seaweed most commonly inhabit the part of a sea that is close to the shore, seaweed occupy a wide range of ecological niches. The highest elevation is only wetted by the tops of sea spray, in some areas, littoral seaweed can extend several miles out to sea. The limiting factor in such cases is sunlight availability, the deepest living seaweed are some species of red algae. Others have adapted to live in rock pools. In this habitat seaweed must withstand rapidly changing temperature and salinity, seaweed has a variety of purposes, for which it is farmed or foraged from the wild. At the beginning of 2011, Indonesia produced 3 million tonnes of seaweed and surpassed the Philippines as the worlds largest seaweed producer, by 2011, the production was estimated to have reached 10 million tonnes. Seaweed is consumed by people, particularly in East Asia, e. g. Japan, China, Korea, Taiwan. In Asia, Gim, nori, zicai are sheets of dried Porphyra used in soups, chondrus crispus is another red alga used in producing food additives, along with Kappaphycus and gigartinoid seaweed. Porphyra is a red alga used in Wales to make laver, laverbread, made from oats and the laver, is a popular dish there. In northern Belize, edible seaweed are mixed with milk, nutmeg, cinnamon, seaweed are also harvested or cultivated for the extraction of alginate, agar and carrageenan, gelatinous substances collectively known as hydrocolloids or phycocolloids
23.
Kelp
–
Kelps are large seaweeds belonging to the brown algae in the order Laminariales. There are about 30 different genera, Kelp grows in underwater forests in shallow oceans, and is thought to have appeared in the Miocene,23 to 5 million years ago. The organisms require nutrient-rich water with temperatures between 6 and 14 °C and they are known for their high growth rate—the genera Macrocystis and Nereocystis can grow as fast as half a metre a day, ultimately reaching 30 to 80 metres. Through the 19th century, the word kelp was closely associated with seaweeds that could be burned to obtain soda ash, the seaweeds used included species from both the orders Laminariales and Fucales. The word kelp was also used directly to refer to these processed ashes, in most kelp, the thallus consists of flat or leaf-like structures known as blades. Blades originate from elongated stem-like structures, the stipes, the holdfast, a root-like structure, anchors the kelp to the substrate of the ocean. Gas-filled bladders form at the base of blades of American species, such as Nereocystis lueteana, growth occurs at the base of the meristem, where the blades and stipe meet. Growth may be limited by grazing, sea urchins, for example, can reduce entire areas to urchin barrens. The kelp life cycle involves a diploid sporophyte and haploid gametophyte stage, the haploid phase begins when the mature organism releases many spores, which then germinate to become male or female gametophytes. Sexual reproduction then results in the beginning of the sporophyte stage. The parenchymatous thalli are generally covered with a layer, rather than cuticle. Kelp may develop dense forests with high production, biodiversity and ecological function, along the Norwegian coast these forests cover 5800 km2, and they support large numbers of animals. Numerous sessile animals are found on kelp stipes and mobile invertebrate fauna are found in high densities on epiphytic algae on the kelp stipes, more than 100,000 mobile invertebrates per square meter are found on kelp stipes and holdfasts in well-developed kelp forests. Giant kelp can be harvested fairly easily because of its surface canopy, bongo kelp ash is rich in iodine and alkali. In great amount, kelp ash can be used in soap, until the Leblanc process was commercialized in the early 19th century, burning of kelp in Scotland was one of the principal industrial sources of soda ash. Alginate, a carbohydrate, is used to thicken products such as ice cream, jelly, salad dressing. Alginate powder is used frequently in general dentistry and orthodontics for making impressions of the upper and lower arches. Kombu is used to flavor broths and stews, as a garnish for rice and other dishes, as a vegetable

Flint axe
–
A flint axe was a Flint tool used during prehistoric times to perform a variety of tasks. These were at first just a cut piece of flint stone used as a hand axe, the stone exhibits a glass-like fracture similar to obsidian, and can be knapped to form large blades. The offcuts were sharp enough to be used a small flint knives and they were widely used during the Neolithic period to clear forests for early farming. They competed with other rocks such as greenstone, which were produced at Langdale in the British Lake District. The polished axes were used directly to cut timber across the grain and they tend to be larger and heavier than the simple axes, and are sometimes known as axe-hammers. Flint nodules are found in Cretaceous chalk deposits, such as those of southern Britain and every where. They were mined during the Neolithic period in many locations, one of the most famous being at Grimes Graves in Norfolk, England
25.
Flue
–
A flue is a duct, pipe, or opening in a chimney for conveying exhaust gases from a fireplace, furnace, water heater, boiler, or generator to the outdoors. Historically the term meant the chimney itself. In the United States, they are known as vents for boilers and as breeching for water heaters. They usually operate by buoyancy, also known as the stack effect, as combustion products contain carbon monoxide and other dangerous compounds, proper draft, and admission of replacement air is imperative. Building codes, and other standards, regulate their materials, design, flues are adjustable and are designed to release noxious gases to the atmosphere. They often have the effect of releasing useful household heat to the atmosphere when not properly set—the very opposite of why the fire was lit in the first place. Fireplaces are one of the biggest energy wasters when the flue is not used properly and this occurs when the flue is left open too wide after the fire is started. Known as convection, warm air from the house is pulled up the chimney, while air from outside is pulled into the house wherever it can enter, including around leaking windows. After the flue heats up from the fire, they are easier to move, but also hotter. Hands should be protected when operating the flue lever, and if a new log is added to the fire, in some countries, wood fire flues are often built into a heat preserving construction within which the flue gases circulate over heat retaining bricks before release to the atmosphere. The heat retaining bricks are covered in a material such as brick. This flue gas circulation avoids the heat loss to the chimney. The heat from the gases is absorbed quickly by the bricks. In a well insulated home, a single load fire burning for one, in this way, less fuel is used, and noxious emissions are reduced. Sometimes, the flue incorporates a second chamber where combustibles in the flue gas are burnt a second time, reducing soot, noxious emissions. The term flue is also used to define certain pipe organ pipes, or rather, roman thermae constructed centuries ago had flues. Another use of the term is for the internal flues of a flued boiler, flue-types include, Open flue—An open flued appliance draws combustion air from its surroundings, exhaust gases rise in a vortex up the open flue. The 19th century Rumford fireplace is an appliance that elegantly refined this principle, closed flue—When an air duct brings combustion air directly to an appliance, there is no air movement between the room containing the appliance

Human flea
–
The human flea is a cosmopolitan flea species that has, in spite of the common name, a wide host spectrum. It is one of six species in the genus Pulex, the five are all confined to the Nearctic. The species is thought to have originated in South America, where its original host may have been the guinea pig or peccary, Pulex irritans is a holometabolous insect with a four-part lifecycle consisting of eggs, larvae, pupae, and adults. Eggs are shed by the female in the environment and hatch into larvae in about 3–4 days, larvae feed on organic debris in the environment. Larvae eventually form pupae, which are in cocoons that are covered with debris from the environment. The larval and pupal stages are completed in about 3–4 weeks when the hatch from pupae. The flea eggs are about 0.5 mm in length and they are oval-shaped and pearly white in color. Eggs are often laid on the body of the host, the larvae are about 0.6 mm in length. They are creamy white or yellow in color, larvae have 13 segments with bristles on each segment. The larvae feed on a variety of organic debris, the pupa are around 4 x 2 mm. After undergoing three separate molts, the larvae pupate, then emerge as adults, if conditions are unfavorable, a cocooned flea can remain dormant for up to a year in the pupal phase. The adults are roughly 1.5 to 4 mm in length and are laterally flattened and they are dark brown in color, are wingless, and have piercing-sucking mouthparts that aid in feeding on the host’s blood. Both genal and pronotal combs are absent and the flea has a rounded head. Most fleas are distributed in the egg, larval, or pupal stages, fleas are a pest species to their hosts, causing an itching sensation that results in discomfort and leads to scratching in the vicinity of the bite. Flea bites generally cause the skin to raise, swell, the bite site has a single puncture point in the center. Bites often appear in clusters or small rows and can remain inflamed for up to several weeks and this species bites many species of mammals and birds, including domesticated ones. It can also be an intermediate host for the flea tapeworm cestode Dipylidium caninum, fleas can spread rapidly and move between areas to include eyebrows, eyelashes, and pubic regions. Hair loss as a result of itching is common, especially in wild, anemia is also possible in extreme cases of high-volume infestations
27.
Pastoralism
–
Pastoralism is the branch of agriculture concerned with the raising of livestock. It is animal husbandry, the care, tending and use of such as camels, goats, cattle, yaks, llamas. Pastoralism generally has an aspect, moving the herds in search of fresh pasture. Pastoralism is a strategy to support a population on less productive land. For example, in savannas, pastoralists and their animals gather when rain water is abundant, pastoralists often use their herds to affect their environment. Grazing herds on savannas can ensure the biodiversity of the savannas, pastoralists may also use fire to make ecosystems more suitable for their food animals. For instance, the Turkana people of northwest Kenya use fire to prevent the invasion of the savanna by woody plant species, biomass of the domesticated and wild animals was increased by a higher quality of grass. Pastoralism is found in many variations throughout the world, composition of herds, management practices, social organization and all other aspects of pastoralism vary between areas and between social groups. Many traditional practices have also had to adapt to the circumstance of the modern world. Ranches of the United States and sheep stations and cattle stations of Australia are seen by some as modern variations, one theory is that pastoralism was created from mixed farming. Bates and Lees proposed that it was the incorporation of irrigation into farming which ensued in specialization, advantages of mixed farming include reducing risk of failure, spreading labour, and re-utilizing resources. The increased productivity of agriculture led to an increase in population. Bordering areas of land remained in use for animal breeding and this meant that large distances had to be covered by herds to collect sufficient forage. Specialization occurred as a result of the importance of both intensive agriculture and pastoralism. Both agriculture and pastoralism developed alongside other, with continuous interactions. There is another theory that suggests pastoralism evolved from hunting and gathering, hunters of wild goats and sheep were knowledgeable about herd mobility and the needs of the animals. Such hunters were mobile and followed the herds on their seasonal rounds, undomesticated herds were chosen to become more controllable for the proto-pastoralist nomadic hunter and gatherer groups by taming and domesticating them. Hunter-gatherers strategies in the past have been diverse and contingent upon the local environment conditions

Barley
–
Barley, a member of the grass family, is a major cereal grain grown in temperate climates globally. It was one of the first cultivated grains, particularly in Eurasia as early as 10,000 years ago, Barley has been used as animal fodder, as a source of fermentable material for beer and certain distilled beverages, and as a component of various health foods. It is used in soups and stews, and in barley bread of various cultures, Barley grains are commonly made into malt in a traditional and ancient method of preparation. In 2014, barley was ranked fourth among grains in quantity produced behind corn, rice, the Old English word for barley was bære, which traces back to Proto-Indo-European and is cognate to the Latin word farina flour. The direct ancestor of modern English barley in Old English was the derived adjective bærlic, the first citation of the form bærlic in the Oxford English Dictionary dates to around 966 CE, in the compound word bærlic-croft. The underived word bære survives in the north of Scotland as bere, the word barn, which originally meant barley-house, is also rooted in these words. Barley is a member of the grass family and it is a self-pollinating, diploid species with 14 chromosomes. The wild ancestor of domesticated barley, Hordeum vulgare subsp, spontaneum, is abundant in grasslands and woodlands throughout the Fertile Crescent area of Western Asia and northeast Africa, and is abundant in disturbed habitats, roadsides and orchards. Outside this region, the barley is less common and is usually found in disturbed habitats. However, in a study of genome-wide diversity markers, Tibet was found to be a center of domestication of cultivated barley. Wild barley has a spike, upon maturity, the spikelets separate. Domesticated barley has nonshattering spikes, making it easier to harvest the mature ears. The nonshattering condition is caused by a mutation in one of two linked genes known as Bt1 and Bt2, many cultivars possess both mutations. The nonshattering condition is recessive, so varieties of barley that exhibit this condition are homozygous for the mutant allele, spikelets are arranged in triplets which alternate along the rachis. In wild barley, only the central spikelet is fertile, while the two are reduced. This condition is retained in certain cultivars known as two-row barleys, a pair of mutations result in fertile lateral spikelets to produce six-row barleys. Recent genetic studies have revealed that a mutation in one gene, two-row barley has a lower protein content than six-row barley, thus a more fermentable sugar content. High-protein barley is best suited for animal feed, Malting barley is usually lower protein which shows more uniform germination, needs shorter steeping, and has less protein in the extract that can make beer cloudy

Ring of Brodgar
–
The Ring of Brodgar is a Neolithic henge and stone circle about 6 miles north-east of Stromness on the Mainland, the largest island in Orkney, Scotland. It is part of the UNESCO World Heritage Site known as the Heart of Neolithic Orkney, the Ring of Brodgar is a Neolithic henge and stone circle in Orkney, Scotland. Most henges do not contain stone circles, Brodgar is a striking exception, the ring of stones stands on a small isthmus between the Lochs of Stenness and Harray. These are the northernmost examples of circle henges in Britain, the site has resisted attempts at scientific dating and the monuments age remains uncertain. It is generally thought to have been erected between 2500 BC and 2000 BC, and was, therefore, the last of the great Neolithic monuments built on the Ness, the results of the excavation are still preliminary. The stone circle is 104 metres in diameter, and the third largest in the British Isles, the ring originally comprised up to 60 stones, of which only 27 remained standing at the end of the 20th century. The tallest stones stand at the south and west of the ring, including the so-called Comet Stone to the south-east. The stones are set within a ditch up to 3 metres deep,9 metres wide and 380 metres in circumference that was carved out of the solid sandstone bedrock by the ancient residents. Technically, this ditch does not constitute a true henge as there is no sign of a bank of earth. The ditch appears to have created in sections, possibly by workforces from different parts of Orkney. The stones may have been an addition, maybe erected over a long period of time. Examination of the immediate environs reveals a concentration of ancient sites, within 2 square miles there are the two circle-henges, four chambered tombs, groups of standing stones, single stones, barrows, cairns, and mounds. The immediate area has yielded a number of flint arrowheads. Although its exact purpose is not known, the proximity of the Standing Stones of Stenness, the site is a scheduled ancient monument and has been recognized as part of the Heart of Neolithic Orkney World Heritage Site in 1999. The Heart of Neolithic Orkney was inscribed as a World Heritage site in December 1999, in addition to the Ring of Brodgar, the site includes Maeshowe, Skara Brae, the Standing Stones of Stenness and other nearby sites. W. L. Ongoing excavations by Orkney College at the nearby Ness of Brodgar site located roughly midway between the Ring and the Stones of Stenness have uncovered several buildings, both ritual and domestic, geophysics suggest there are likely to be more in the vicinity. Pottery, bones, stone tools and a polished stone mace head have also been discovered, perhaps the most important find is the remains of a large stone wall which may have been 100 metres long and up to 6 metres wide. It appears to traverse the entire peninsula the site is on, invaders from Scandinavia reached Orkney by the 9th century, bringing a complex theology that they imposed on the preexisting Orcadian monuments, at least according to local legend

Standing Stones of Stenness
–
The Standing Stones of Stenness is a Neolithic monument five miles northeast of Stromness on the mainland of Orkney, Scotland. This may be the oldest henge site in the British Isles, various traditions associated with the stones survived into the modern era and they form part of the Heart of Neolithic Orkney World Heritage Site. They are looked after by Historic Scotland, the surviving stones are sited on a promontory at the south bank of the stream that joins the southern ends of the sea loch Loch of Stenness and the freshwater Loch of Harray. The name, which is pronounced stane-is in Orcadian dialect, comes from Old Norse meaning stone headland, although the site today lacks the encircling ditch and bank, excavation has shown that this used to be a henge monument, possibly the oldest in the British Isles. The stones are thin slabs, approximately 300 mm thick with sharply angled tops. Four, up to about 5 m high, were elements of a stone circle of up to 12 stones. The ditch is cut into rock by as much as 2 m and is 7 m wide, surrounded by an earth bank, the entrance faces towards the Neolithic Barnhouse Settlement which has been found adjacent to the Loch of Harray. The Watch Stone stands outside the circle to the north-west and is 5.6 m high, once there were at least two stones there, as in the 1930s the stump of a second stone was found. Other smaller stones include a stone setting in the centre of the circle platform where cremated bone, charcoal. This is referred to as a hearth, similar to the one found at Barnhouse, animal bones were found in the ditch. The pottery links the monument to Skara Brae and Maeshowe, based on radiocarbon dating, it is thought that work on the site had begun by 3100 BC. Even in the 18th century the site was associated with traditions and rituals. It was visited by Walter Scott in 1814, other antiquarians documented the stones and recorded local traditions and beliefs about them. It was also associated with ceremonies and believed to have magical power. There was a tradition of making all kinds of oaths or promises with ones hand in the Odin Stone. He started in December 1814 by smashing the Odin Stone and this caused outrage and he was stopped after destroying one other stone and toppling another. The toppled stone was re-erected in 1906 along with some inaccurate reconstruction inside the circle, in the 1970s, a dolmen structure was toppled, since there were doubts as to its authenticity. The two upright stones remain in place, a picture of the Stones of Stenness features on the cover of Van Morrisons album The Philosophers Stone, and the Odin stone is depicted on Julian Copes album Discover Odin

Maeshowe
–
Maeshowe is a Neolithic chambered cairn and passage grave situated on Mainland, Orkney, Scotland. It was probably built around 2800 BC and it gives its name to the Maeshowe type of chambered cairn, which is limited to Orkney. The monuments around Maeshowe, including Skara Brae, were designated a UNESCO World Heritage Site in 1999, Maeshowe is one of the largest tombs in Orkney, the mound encasing the tomb is 115 feet in diameter and rises to a height of 24 feet. Surrounding the mound, at a distance of 50 feet to 70 feet is a ditch up to 45 feet wide, the grass mound hides a complex of passages and chambers built of carefully crafted slabs of flagstone weighing up to 30 tons. It is aligned so that the wall of its central chamber held up by a bracketed wall, is illuminated on the winter solstice. A similar display occurs in Newgrange and this entrance passage is 36 feet long and leads to the central almost square chamber measuring about 15 feet on each side. The current height of the chamber is 12.5 feet, the original roof may have risen to a height of 15 feet or more. The entrance passage is only about 3 feet high, requiring visitors to stoop or crawl into the central chamber and that chamber is constructed largely of flat slabs of stone, many of which traverse nearly the entire length of the walls. In each corner lie huge angled buttresses that rise to the vaulting, at a height of about 3 feet, the walls construction changes from the use of flat to overlapping slabs creating a beehive-shaped vault. Estimates of the amount of required to build Maeshowe vary. Dating of the construction of Maeshowe is difficult but dates derived from burials in similar tombs cluster around 3000 BC. Since Maeshowe is the largest and most sophisticated example of the Maeshowe type of tomb, archaeologists have suggested that it is the last of its class, built around 2800 BC. The people who built Maeshowe were users of grooved ware, a type of pottery that spread throughout the British Isles from about 3000 BC. Maeshowe appears as a mound rising from a flat plain near the southeast end of the Loch of Harray. Maeshowe is aligned with some other Neolithic sites in the vicinity, in addition, the so-called Barnhouse Stone in a field around 700 metres away is perfectly aligned with the entrance to Maeshowe. This entrance corridor is so placed that it lets the light of the setting sun into the chamber for a few days each side of the winter solstice. A Neolithic low road connects Maeshowe with the magnificently preserved village of Skara Brae, passing near the Standing Stones of Stenness, low roads connect Neolithic ceremonial sites throughout Britain. Some archeologists believe that Maeshowe was originally surrounded by a stone circle

Carbon-14
–
Carbon-14, 14C, or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby, Carbon-14 was discovered on 27 February 1940, by Martin Kamen and Sam Ruben at the University of California Radiation Laboratory in Berkeley, California. Its existence had been suggested by Franz Kurie in 1934, carbon-12 and carbon-13 are both stable, while the half-life of carbon-14 is 5, 730±40 years. Carbon-14 decays into nitrogen-14 through beta decay, a gram of carbon containing 1 atom of carbon-14 per 1012 atoms will emit 0.40 beta particles per second. The primary natural source of carbon-14 on Earth is cosmic ray action on nitrogen in the atmosphere, however, open-air nuclear testing between 1955–1980 contributed to this pool. The different isotopes of carbon do not differ appreciably in their chemical properties, the emitted beta particles have a maximum energy of 156 keV, while their weighted mean energy is 49 keV. These are relatively low energies, the distance traveled is estimated to be 22 cm in air and 0.27 mm in body tissue. The fraction of the radiation transmitted through the dead layer is estimated to be 0.11. Liquid scintillation counting is the preferred method, the G-M counting efficiency is estimated to be 3%. The half-distance layer in water is 0.05 mm. Radiocarbon dating is a dating method that uses to determine the age of carbonaceous materials up to about 60,000 years old. The technique was developed by Willard Libby and his colleagues in 1949 during his tenure as a professor at the University of Chicago, in 1960, Libby was awarded the Nobel Prize in chemistry for this work. One of the frequent uses of the technique is to date organic remains from archaeological sites, plants fix atmospheric carbon during photosynthesis, so the level of 14C in plants and animals when they die approximately equals the level of 14C in the atmosphere at that time. However, it decreases thereafter from radioactive decay, allowing the date of death or fixation to be estimated. A calculation or a comparison of carbon-14 levels in a sample, with tree ring or cave-deposit carbon-14 levels of a known age. Carbon-14 is produced in the layers of the troposphere and the stratosphere by thermal neutrons absorbed by nitrogen atoms. When cosmic rays enter the atmosphere, they undergo various transformations, the resulting neutrons participate in the following reaction, n +14 7N →14 6C + p The highest rate of carbon-14 production takes place at altitudes of 9 to 15 km and at high geomagnetic latitudes. Production rates vary because of changes to the cosmic ray flux caused by the heliospheric modulation, the latter can create significant variations in 14C production rates, although the changes of the carbon cycle can make these effects difficult to tease out. Another extraordinarily large 14C increase has been associated with the 5480 BC event

Fresh water
–
Fresh water is generally characterized by having low concentrations of dissolved salts and other total dissolved solids. The term specifically excludes seawater and brackish water although it does include mineral-rich waters such as chalybeate springs, the term sweet water has been used to describe fresh water in contrast to salt water. The term fresh water does not have the meaning as potable water. Much of the fresh water and ground water is unsuitable for drinking without some form of purification because of the presence of chemical or biological contaminants. It may also be in contact with the underlying underground water. The majority of water on Earth is in ice caps. The source of almost all water is precipitation from the atmosphere, in the form of mist, rain. Fresh water falling as mist, rain or snow contains materials dissolved from the atmosphere and material from the sea, in some cases this acid rain results in pollution of lakes and rivers. In coastal areas fresh water may contain significant concentrations of salts derived from the sea if windy conditions have lifted drops of seawater into the rain-bearing clouds. This can give rise to elevated concentrations of sodium, chloride, magnesium, significant quantities of iron may be transported in this way including the well-documented transfer of iron-rich rainfall falling in Brazil derived from sand-storms in the Sahara in north Africa. Water is an issue for the survival of all living organisms. Some can use water but many organisms including the great majority of higher plants. Out of all the water on Earth, saline water in oceans, seas and saline groundwater make up about 97% of it. Freshwater lakes contain about 87% of this surface water, including 29% in the African Great Lakes, 20% in Lake Baikal in Russia, 21% in the North American Great Lakes. Swamps have most of the balance only a small amount in rivers. In areas with no water on the ground surface, fresh water derived from precipitation may, because of its lower density. Most of the fresh water is frozen in ice sheets. Many areas suffer from lack of distribution of water, such as deserts

Dune
–
In physical geography, a dune is a hill of loose sand built by wind or the flow of water. Dunes occur in different shapes and sizes, formed by interaction with the flow of air or water, most kinds of dunes are longer on the windward side where the sand is pushed up the dune and have a shorter slip face in the lee of the wind. The valley or trough between dunes is called a slack, a dune field is an area covered by extensive sand dunes. Dunes occur, for example, in deserts and along some coasts. Some coastal areas have one or more sets of dunes running parallel to the shoreline directly inland from the beach, in most cases, the dunes are important in protecting the land against potential ravages by storm waves from the sea. Although the most widely distributed dunes are those associated with coastal regions, Dunes can form under the action of water flow, and on sand or gravel beds of rivers, estuaries and the sea-bed. The modern word dune came into English from French c,1790, which in turn came from Middle Dutch dūne. Crescent-shaped mounds are generally wider than they are long, the slipfaces are on the concave sides of the dunes. These dunes form under winds that blow consistently from one direction, some types of crescentic dunes move more quickly over desert surfaces than any other type of dune. A group of dunes moved more than 100 metres per year between 1954 and 1959 in Chinas Ningxia Province, and similar speeds have been recorded in the Western Desert of Egypt. The largest crescentic dunes on Earth, with mean crest-to-crest widths of more than three kilometres, are in Chinas Taklamakan Desert. They may be composed of clay, silt, sand, or gypsum, eroded from the floor or shore, transported up the concave side of the dune. Examples in Australia are up to 6.5 km long,1 km wide and they also occur in southern and West Africa, and in parts of the western United States, especially Texas. Straight or slightly sinuous sand ridges typically much longer than they are wide are known as linear dunes and they may be more than 160 kilometres long. Some linear dunes merge to form Y-shaped compound dunes, many form in bidirectional wind regimes. The long axes of these dunes extend in the resultant direction of sand movement, linear loess hills known as pahas are superficially similar. These hills appear to have formed during the last ice age under permafrost conditions dominated by sparse tundra vegetation. Radially symmetrical, star dunes are pyramidal sand mounds with slipfaces on three or more arms that radiate from the center of the mound

Carved Stone Balls
–
Carved Stone Balls are petrospheres, usually round and rarely oval. They have from 3 to 160 protruding knobs on the surface and they range from having no ornamentation to extensive and highly varied engraved patterns. A wide range of theories have been produced to explain their use or significance and they are not to be confused with the much larger smooth round stone spheres of Costa Rica. Carved Stone Balls are up to 5200 years old, coming from the late Neolithic to at least the Bronze Age, nearly all have been found in north-east Scotland, the majority in Aberdeenshire, the fertile land lying to the east of the Grampian Mountains. A similar distribution to that of Pictish symbols led to the suggestion that Carved Stone Balls are Pictish artefacts. The core distribution also reflects that of the Recumbent stone circles, as objects they are very easy to transport and a few have been found on Iona, Skye, Harris, Uist, Lewis, Arran, Hawick, Wigtownshire and fifteen from Orkney. Outside Scotland examples have found in Ireland at Ballymena, and in England at Durham, Cumbria, Lowick. The larger balls are all from Aberdeenshire, bar one from Newburgh in Fife, by the late 1970s a total of 387 had been recorded. Of these, by far the greatest concentration was found in Aberdeenshire, by 1983 the number had risen to 411. By 2015 a total of over 425 balls were recorded, a collection of over 30 carved balls from Scotland, Ireland and northern England is in the British Museums collection. Many of the balls have not had their discovery site recorded, five were found at Skara Brae village and one at the Dunadd hillfort. The distribution of the balls is similar to that of mace-heads, the lack of context is likely to distort the interpretation. Random finds are likely to have been picked up and entered a collection if they were aesthetically appealing. Damaged and plain balls were likely to find a market than decorated examples so some more decorated examples might be fraudulent. In 2013, archaeologists discovered a stone ball at Ness of Brodgar. Many are said to be made of greenstone, but this is a term for all varieties of dark, greenish igneous rocks, including diorites, serpentinite. Forty-three are sandstone, including Old Red Sandstone,26 greenstone and 12 quartzite, nine were serpentinite and these had been carved. Some were made of gabbro, and a material to carve

River Boyne
–
The River Boyne is a river in Leinster, Ireland, the course of which is about 112 kilometres long. Salmon and trout can be caught in the river, which is surrounded by the Boyne Valley and it is crossed just west of Drogheda by the Boyne River Bridge that carries the M1 motorway and by the Boyne Viaduct that carries the Dublin-Belfast railway line to the east. The catchment area of the River Boyne is 2,695 km2, the long term average flow rate of the River Boyne is 38.8 Cubic Metres per second Despite its short course, the Boyne has historical, archaeological and mythical connotations. The Battle of the Boyne, a battle in Irish history. It passes near the ancient city of Trim, Trim Castle, the Hill of Tara, Navan, the Hill of Slane, Brú na Bóinne, Mellifont Abbey, and the medieval city of Drogheda. In the Boyne Valley can also be found other historical and archaeological monuments, like Loughcrew, Kells, Celtic crosses, castles and this river has been known since ancient times. The Greek geographer Ptolemy drew a map of Ireland in the 2nd century which included the Boyne, which he called Βουουινδα, and somewhat later Giraldus Cambrensis called it Boandus. In Irish mythology it is said that the river was created by the goddess Boann, according to F. Dinneen, lexicographer of the Irish Gaelic language, in other legends, it was in this river where Fionn mac Cumhail captured Fiontán, the Salmon of Knowledge. The Meath section of the Boyne was also known as Smior Fionn Feidhlimthe, the Boyne Navigation is a series of canals running roughly parallel to the main river from Oldbridge near Drogheda to Navan. Owned by An Taisce and mostly derelict, the Inland Waterways Association of Ireland are restoring the navigation to navigable status, the canal at Oldbridge which runs through the battle of the Boyne Site was the first to be restored. A rock with indications of being Prehistoric art was found in August 2013, cliadh O’Gibne reported through the Archaeological Survey of Ireland that a boulder with geometric carvings had been found in Donore, County Meath. Initial examination by an underwater archaeologist, suggests it could be very rare because, unlike other log-boats found here, the vessel is to be excavated as it poses a hazard to navigation.

Ochre
–
Ochre (/ˈoʊkər/ OH-kər, from Greek, ὠχρός, ōkhrós, or ocher, is a natural earth pigment containing hydrated iron oxide, which ranges in color from yellow to deep orange or brown. It is also the name of the produced by this pigment. A variant of ochre containing an amount of hematite, or dehydrated iron oxide, has a reddish tint known as red ochre. Ochre is a family of pigments, which includes yellow ochre, red ochre, purple ochre, sienna. The major ingredient of all the ochres is iron oxide-hydroxide, known as limonite, which gives them a yellow color. Yellow ochre, FeO·nH 2O, is a hydrated iron hydroxide also called gold ochre Red ochre, Fe 2O3, takes its color from the mineral hematite. Purple ochre, is identical to red ochre chemically but of a different hue caused by different light diffraction properties associated with an average particle size. Brown ochre, also FeO, is a hydrated iron oxide. Sienna contains both limonite and an amount of manganese oxide, which makes it darker than ochre. Umber pigments contain a proportion of manganese which make them a dark brown. When natural sienna and umber pigments are heated, they are dehydrated and some of the limonite is transformed into hematite, giving them more reddish colors, called burnt sienna and burnt umber. Ochres are non-toxic, and can be used to make an oil paint that dries quickly, modern ochre pigments often are made using synthetic iron oxide. Pigments which use natural ochre pigments indicate it with the name PY-43 on the label, pieces of ochre engraved with abstract designs have been found at the site of the Blombos Cave in South Africa, dated to around 75,000 years ago. In Wales, the paleolithic burial called the Red Lady of Paviland from its coating of red ochre has been dated to around 33,000 years before present. Paintings of animals made with red and yellow ochre pigments have been found in sites at Pech Merle in France. The cave of Lascaux has an image of a horse colored with yellow estimated to be 17,300 years old. In Ancient Egypt, yellow was associated with gold, which was considered to be eternal, the skin and bones of the gods were believed to be made of gold. The Egyptians used yellow extensively in tomb painting, though occasionally they used orpiment

Body painting
–
Body painting, or sometimes bodypainting, is a form of body art. Unlike tattoo and other forms of art, body painting is temporary, painted onto the human skin. Body painting that is limited to the face is known as face painting, body painting with clay and other natural pigments existed in most, if not all, tribalist cultures. Often worn during ceremonies, it survives in this ancient form among the indigenous people of Australia, New Zealand. A semi-permanent form of painting known as Mehndi, using dyes made of henna leaves, was and is still practiced in India]. Since the late 1990s, Mehndi has become popular amongst young women in the Western world, many indigenous peoples of Central and South America paint Jagua Tattoos, or designs with Genipa americana juice on their bodies. Indigenous peoples of South America traditionally use annatto, huito, or wet charcoal to decorate their faces and bodies, huito is semi-permanent, and it generally takes weeks for this black dye to fade. Actors and clowns around the world have painted their faces—and sometimes bodies—for centuries, more subdued form of face paints for everyday occasions evolved into the cosmetics we know today. Body painting is not always large pieces on fully nude bodies, even today there is a constant debate about the legitimacy of body painting as an art form. Body art today evolves to the works more directed personal mythologies, as Jana Sterbak, Rebecca Horn, Youri Messen-Jaschin. Body painting is used as a method of gaining attention in political protests. French artist Yves Klein is perhaps the most famous for this, the effect produced by this technique creates an image-transfer from the models body to the medium. This includes all the curves of the body being reflected in the outline of the image. This technique was not necessarily monotone, multiple colors on different body parts sometimes produced interesting effects, Joanne Gair is a body paint artist whose work appeared for the tenth consecutive year in the 2008 Sports Illustrated Swimsuit Issue. She burst into prominence with an August 1992 Vanity Fair Demis Birthday Suit cover of Demi Moore and her Disappearing Model was part of an episode of Ripleys Believe It or Not. Body painting festivals happen annually across the world, bringing together professional body painters as well as keen amateurs, body paintings can also typically be seen at football matches, at rave parties, and at certain festivals. The World Bodypainting Festival in Pörtschach in Austria is the biggest art event in the bodypainting theme and this particular form of creative art is defined Skin Art. The 1960s supermodel Veruschka is a much appreciated muze for bodypaint artists, images of her in the book Transfigurations by photographer Holger Trulzsch have frequently been emulated

Hematite
–
Hematite, also spelled as haematite, is the mineral form of iron oxide, one of several iron oxides. Hematite crystallizes in the lattice system, and it has the same crystal structure as ilmenite. Hematite and ilmenite form a solid solution at temperatures above 950 °C. Hematite is colored black to steel or silver-gray, brown to reddish brown and it is mined as the main ore of iron. Varieties include kidney ore, martite, iron rose and specularite, while the forms of hematite vary, they all have a rust-red streak. Hematite is harder than iron, but much more brittle. Maghemite is a hematite- and magnetite-related oxide mineral, huge deposits of hematite are found in banded iron formations. Gray hematite is typically found in places that can have still standing water or mineral hot springs, the mineral can precipitate out of water and collect in layers at the bottom of a lake, spring, or other standing water. Hematite can also occur without water, however, usually as the result of volcanic activity, the name hematite is derived from the Greek word for blood αἷμα haima, due to the red coloration found in some varities of hematite. The color of hematite lends itself to use as a pigment, ochre is a clay that is colored by varying amounts of hematite, varying between 20% and 70%. Red ochre contains unhydrated hematite, whereas yellow ochre contains hydrated hematite, the principal use of ochre is for tinting with a permanent color. The red chalk writing of this mineral was one of the earliest in the history of humans, the powdery mineral was first used 164,000 years ago by the Pinnacle-Point man possibly for social purposes. Hematite residues are found in graves from 80,000 years ago. Near Rydno in Poland and Lovas in Hungary red chalk mines have been found that are from 5000 BC, rich deposits of hematite have been found on the island of Elba that have been mined since the time of the Etruscans. Adding to the surprise was a transition with a decrease in temperature at around 260 K to a phase with no net magnetic moment. The disappearance of the moment with a decrease in temperature at 260 K is caused by a change in the anisotropy which causes the moments to align along the c axis, in this configuration, spin canting does not reduce the energy. The magnetic properties of bulk hematite differ from their nanoscale counterparts, for example, the Morin transition temperature of hematite decreases with a decrease in the particle size. Two other end-members are referred to as protohematite and hydrohematite, enhanced magnetic coercivities for hematite have been achieved by dry-heating a 2-line ferrihydrite precursor prepared from solution

Baleen
–
Baleen is a filter-feeder system inside the mouths of baleen whales. The baleen system works by opening its mouth underwater and taking in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen, Baleen is similar to bristles and is made of keratin, the same substance found in human fingernails and hair. Some whales, such as the whale, have longer baleen than others. Other whales, such as the whale, only use one side of their baleen. These baleen bristles are arranged in plates across the jaw of the whale. Baleen is often called whalebone, but that also can refer to the normal bones of whales. Depending on the species, a plate can be 0.5 to 3.5 metres long. Its hairy fringes are called baleen hair or whalebone-hair and they are also called baleen bristles, which in sei whales are highly calcified, calcification functioning to increase their stiffness. Baleen plates are broader at the gumline, the plates have been compared to sieves or Venetian blinds. The word baleen derives from the Latin bālaena, related to the Greek phalaina – both of which mean whale, the oldest true fossils of baleen are only 15 million years old, but baleen rarely fossilizes, and scientists believe it originated considerably earlier than that. Baleen is believed to have evolved around thirty years ago, possibly from a hard, gummy upper jaw, like the one a Dalls porpoise has. The transition from teeth to baleen is proposed to have occurred stepwise and it is known that modern mysticetes have teeth initially and then develop baleen plate germs in utero, but lose their dentition and have only baleen during their juvenile years and adulthood. However, developing mysticetes do not produce tooth enamel because at some point this trait evolved to become a pseudogene and this is likely to have occurred about 28 million years ago and proves that dentition is an ancestral state of mysticetes. Further research suggests that the baleen of Aetiocetus was arranged in bundles between widely spaced teeth, if true, this combination of baleen and dentition in Aetiocetus would act as a transition state between odontocetes and mysticetes. It would be unlikely for all of these changes to occur at once. Therefore, it is proposed that Oligocene aetiocetids possess both ancestral and descendent character states regarding feeding strategies and this makes them mosaic taxa, showing that either baleen evolved before dentition was lost or that the traits for filter feeding originally evolved for other functions. It also shows that the evolution could have occurred gradually because the state was originally maintained

Walrus
–
The walrus is a large flippered marine mammal with a discontinuous distribution about the North Pole in the Arctic Ocean and subarctic seas of the Northern Hemisphere. The walrus is the living species in the family Odobenidae. Adult walruses are easily recognized by their prominent tusks, whiskers, adult males in the Pacific can weigh more than 2,000 kg and, among pinnipeds, are exceeded in size only by the two species of elephant seals. Walruses live mostly in shallow waters above the shelves, spending significant amounts of their lives on the sea ice looking for benthic bivalve mollusks to eat. Walruses are relatively long-lived, social animals, and they are considered to be a species in the Arctic marine regions. The walrus has played a prominent role in the cultures of many indigenous Arctic peoples, who have hunted the walrus for its meat, fat, skin, tusks, and bone. During the 19th century and the early 20th century, walruses were widely hunted and killed for their blubber, walrus ivory, the population of walruses dropped rapidly all around the Arctic region. Their population has rebounded somewhat since then, though the populations of Atlantic and Laptev walruses remain fragmented, the origin of the word walrus is thought by J. R. R. Tolkien to derive from a Germanic language, and it has been attributed largely to either the Dutch language or Old Norse and its first part is thought to derive from a word such as Dutch walvis whale. Its second part has also hypothesized to come from the Old Norse word for horse. For example, the Old Norse word hrossvalr means horse-whale and is thought to have passed in an inverted form to both Dutch and the dialects of northern Germany as walros and Walross. An alternate theory is that is comes from the Dutch words wal shore, the species name rosmarus is Scandinavian. The Norwegian manuscript Konungsskuggsja, thought to date from around AD1240, refers to the walrus as rosmhvalr in Iceland and rostungr in Greenland. Several place names in Iceland, Greenland and Norway may originate from sites, Hvalfjord, Hvallatrar and Hvalsnes to name some. The archaic English word for walrus—morse—is widely thought to have come from the Slavic languages, compare морж in Russian, mursu in Finnish, morša in Northern Saami, and morse in French. The coincidental similarity between morse and the Latin word morsus supposedly contributed to the reputation as a terrible monster. The compound Odobenus comes from odous and baino, based on observations of walruses using their tusks to pull out of the water. The term divergens in Latin means turning apart, referring to their tusks, the walrus is a mammal in the order Carnivora

Ivory
–
Ivory is a hard, white material from the tusks and teeth of animals, that can be used in art or manufacturing. It consists mainly of dentine ), one of the structures of teeth. The chemical structure of the teeth and tusks of mammals is the same and it has been valued since ancient times for making a range of items, from ivory carvings to false teeth, fans, and dominoes. Elephant ivory is the most important source, but ivory from mammoth, walrus, hippopotamus, sperm whale, killer whale, narwhal, elk also have two ivory teeth, which are believed to be the remnants of tusks from their ancestors. The national and international trade in ivory of threatened species such as African and Asian elephants is illegal, the word ivory ultimately derives from the ancient Egyptian âb, âbu, through the Latin ebor- or ebur. Both the Greek and Roman civilizations practiced ivory carving to make large quantities of high value works of art, precious religious objects, Ivory was often used to form the white of the eyes of statues. There is some evidence of either whale or walrus ivory used by the ancient Irish, solinus, a Roman writer in the 3rd century claimed that the Celtic peoples in Ireland would decorate their sword-hilts with the teeth of beasts that swim in the sea. Adomnan of Iona wrote a story about St Columba giving a sword decorated with carved ivory as a gift that a penitent would bring to his master so he could redeem himself from slavery. The Syrian and North African elephant populations were reduced to extinction, the Chinese have long valued ivory for both art and utilitarian objects. Southeast Asian kingdoms included tusks of the Indian elephant in their annual tribute caravans to China, Chinese craftsmen carved ivory to make everything from images of deities to the pipe stems and end pieces of opium pipes. The Buddhist cultures of Southeast Asia, including Myanmar, Thailand, Laos and Cambodia, Ivory was prized for containers due to its ability to keep an airtight seal. It was also carved into elaborate seals utilized by officials to sign documents. In Southeast Asian countries, where Muslim Malay peoples live, such as Malaysia, Indonesia, in the Philippines, ivory was also used to craft the faces and hands of Catholic icons and images of saints prevalent in the Santero culture. Tooth and tusk ivory can be carved into a vast variety of shapes, examples of modern carved ivory objects are okimono, netsukes, jewelry, flatware handles, furniture inlays, and piano keys. Additionally, warthog tusks, and teeth from sperm whales, orcas and hippos can also be scrimshawed or superficially carved, Ivory usage in the last thirty years has moved towards mass production of souvenirs and jewelry. In Japan, the increase in wealth sparked consumption of solid ivory hanko – name seals – which before this time had made of wood. Prior to the introduction of plastics, ivory had many ornamental and practical uses and it was formerly used to make cutlery handles, billiard balls, piano keys, Scottish bagpipes, buttons and a wide range of ornamental items. Ivory can be taken from dead animals – however, most ivory came from elephants that were killed for their tusks, for example, in 1930 to acquire 40 tons of ivory required the killing of approximately 700 elephants

Killer whale
–
The killer whale or orca is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and they have been known to attack baleen whale calves, and even adult whales. Killer whales are apex predators, as there is no animal that preys on them, Killer whales are considered a cosmopolitan species, and can be found in each of the worlds oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas. Killer whales are social, some populations are composed of matrilineal family groups which are the most stable of any animal species. Their sophisticated hunting techniques and vocal behaviours, which are specific to a particular group. Some local populations are considered threatened or endangered due to depletion, habitat loss, pollution, capture for marine mammal parks. In late 2005, the Southern Resident Killer Whales, the population that inhabits British Columbia, Wild killer whales are not considered a threat to humans, but there have been cases of captive orcas killing or injuring their handlers at marine theme parks. Killer whales feature strongly in the mythologies of cultures, with their reputation ranging from being the souls of humans to merciless killers. Orcinus orca is the only recognized extant species in the genus Orcinus, the killer whale is one of 35 species in the oceanic dolphin family, which first appeared about 11 million years ago. The killer whale lineage probably branched off shortly thereafter, english-speaking scientists most often use the term killer whale, although the term orca is increasingly used. Killer whale advocates point out it has a long heritage, indeed, the genus name Orcinus means of the kingdom of the dead, or belonging to Orcus. Ancient Romans originally applied orca to these animals, possibly borrowing it from the Greek ὄρυξ, since the 1960s, orca has steadily grown in popularity, both names are now used. According to some authors, the killer whale is a mistranslation of the 18th century Spanish name asesina-ballenas which means literally whale killer. Basque whalers would have given it such name after observing pods of orcas hunting baleen whales and they are sometimes referred to as blackfish, a name also used for other whale species. Grampus is a name for the species, but is now seldom used. This meaning of grampus should not be confused with the genus Grampus, the three to five types of killer whales may be distinct enough to be considered different races, subspecies, or possibly even species. Residents diets consist primarily of fish and sometimes squid, and they live in complex, female residents characteristically have rounded dorsal fin tips that terminate in a sharp corner

Bradawl
–
A bradawl is a woodworking hand tool with a blade similar to that of a straight screwdriver and a handle made from wood or plastic. A bradawl is used to make an indentation in wood or other materials in order to ease the insertion of a nail or screw, the blade is placed across the fibres of the wood, cutting them when pressure is applied. The bradawl is then twisted through 90 degrees which displaces the fibres creating a hole and this cutting action helps to prevent splitting of the wood along the grain

Bead
–
Beads range in size from under 1 millimetre to over 1 centimetre in diameter. A pair of beads made from Nassarius sea snail shells, approximately 100,000 years old, are thought to be the earliest known examples of jewellery, beadwork is the art or craft of making things with beads. Beads can be together with specialized thread, strung onto thread or soft, flexible wire. In some cases, such as millefiori and cloisonné beads, multiple categories may overlap in an interdependent fashion, Beads can be made of many different materials. The earliest beads were made of a variety of materials which, after they were gathered. As humans became capable of obtaining and working with more difficult materials, more recently, synthetic materials were added. In modern manufacturing, the most common materials are wood, plastic, glass, metal. Beads are still made from naturally occurring materials, both organic and inorganic. However, some of these materials now routinely undergo some extra processing beyond mere shaping and drilling such as color enhancement via dyes or irradiation, the natural organics include bone, coral, horn, ivory, seeds, animal shell, and wood. For most of human history pearls were the ultimate precious beads of natural origin because of their rarity, amber and jet are also of natural organic origin although both are the result of partial fossilization. The natural inorganics include various types of stones, ranging from gemstones to common minerals, and metals. Of the latter, only a few precious metals occur in pure forms, the oldest-surviving synthetic materials used for beadmaking have generally been ceramics, pottery and glass. Beads were also made from ancient alloys such as bronze and brass, many different subtypes of glass are now used for beadmaking, some of which have their own component-specific names. Lead crystal beads have a percentage of lead oxide in the glass formula. Most of the other named glass types have their formulations and patterns inseparable from the manufacturing process, plastic toy beads, made by chopping plastic tubes into short pieces, were introduced in 1958 by Munkplast AB in Munka-Ljungby, Sweden, under the brand Nabbi. Known as Indian beads, they were sewn together to form ribbons. The pegboard for bead designs was invented in the early 1960s by Gunnar Knutsson in Vällingby, Sweden, as a therapy for elderly homes, the bead designs were glued to cardboard or Masonite boards and used as trivets. Later, when the beads were made of polyethylene, it possible to fuse them with a flat iron

Adze
–
The adze is a cutting tool shaped somewhat like an axe that dates back to the stone age. It can be any tool with a cutting edge. Adzes are used for smoothing or carving wood in hand woodworking, similar to an axe, the blade of an adze is set at right angles to the tools shaft, in contrast to an axes blade, which is in plane with the shaft. A similar, but blunt, tool used for digging in hard ground is called a mattock, the adze is depicted in ancient Egypt art from the Old Kingdom onward. Originally the adze blades were made of stone, but already in the Predynastic Period copper adzes had all, while stone blades were fastened to the wooden handle by tying, metal blades had sockets into which the handle was fitted. Examples of Egyptian adzes can be found in museums and on the Petrie Museum website, a depiction of an adze was also used as a hieroglyph, representing the consonants stp, chosen, and used as. Pharaoh XX, chosen of God/Goddess YY. The ahnetjer depicted as an instrument, was used in the Opening of the Mouth ceremony. It was apparently the foreleg of a freshly sacrificed bull or cow with which the mouth was touched, as iron-age technology moved south into Africa with migrating ancient Egyptians, they carried their technology with them, including adzes. Prehistoric Māori adzes from New Zealand, used for carving, were made from nephrite. At the same time on Henderson Island, a coral island in eastern Polynesia lacking any rock other than limestone. American Northwest coast native peoples traditionally used adzes for both construction and art. Northwest coast adzes take two forms, hafted and D-handle, the hafted form is similar in form to a European adze with the haft constructed from a natural crooked branch which approximately forms a 60% angle. The thin end is used as the handle and the end is flattened and notched such that an adze iron can be lashed to it. Modern hafts are sometimes constructed from a blank with a dowel added for strength at the crook. The second form is the D-handle adze which is basically an iron with a directly attached handle. The D-handle therefore provides no mechanical leverage, Northwest coast adzes are often classified by size and iron shape vs. role. As with European adzes, iron shapes include straight, gutter, final surfacing is sometimes performed with a crooked knife. Ground stone adzes are still in use by a variety of people in Irian Jaya, Papua New Guinea, the hardstone is ground on a riverine rock with the help of water until it has got the desired shape

Shovel
–
A shovel is a tool for digging, lifting, and moving bulk materials, such as soil, coal, gravel, snow, sand, or ore. Most shovels are hand tools consisting of a blade fixed to a medium-length handle. Shovel blades are made of sheet steel or hard plastics and are very strong. Shovel handles are made of wood or glass-reinforced plastic. Hand shovel blades made of sheet steel usually have a seam or hem at the back to make a socket for the handle. This fold also commonly provides extra rigidity to the blade, the handles are usually riveted in place. A T-piece is commonly fitted to the end of the handle to aid grip and control where the shovel is designed for moving soil and these designs can all be easily mass-produced. The term shovel also applies to larger excavating machines called power shovels, which serve the same purpose—digging, lifting, modern power shovels descend from steam shovels. Loaders and excavators perform similar work, etically speaking, but are not classified as shovels emically, hand shovels have been adapted for many different tasks and environments. They can be optimized for a task or designed as cross-over or compromise multitaskers. In neolithic times and earlier a large animals scapula was used as a crude shovel or spade. It is via this connection between shoulder blades and digging blades that the words spatula and spade both have etymologic connection with scapulas, manual shoveling was the chief means of excavation in construction until mechanization via steam shovels and later hydraulic equipment gradually replaced most manual shoveling. The same is true of the history of mining and quarrying. Railroad cars and cargo holds containing ore, coal, gravel, sand and these industries did not always rely exclusively on such work, but such work was a ubiquitous part of them. Until the 1950s, manual shoveling employed large numbers of workers, thus the cost of labor, even when each individual worker was poorly paid, was a tremendous expense of operations. Productivity of the business was tied mostly to labor productivity and it still often is even today, but in the past it was even more so. In industrial and commercial materials handling, hand shoveling was later replaced not only with loaders, Taylor, with his focus on time and motion study, took an interest in differentiating the many motions of manual labor to a far greater degree than others tended to. Taylor realized that failing to analyze shoveling practice represented an opportunity to discover or synthesize best practices for shoveling

Passage grave
–
A passage grave or passage tomb consists of a narrow passage made of large stones and one or multiple burial chambers covered in earth or stone. The building of tombs was normally carried out with megaliths and smaller stones. Those with more than one chamber may have multiple sub-chambers leading off from the burial chamber. One common layout, the passage grave, is cross-shaped. Sometimes passage tombs are covered with a cairn, especially those dating from later times, not all passage graves have been found to contain evidence of human remains. Passage tombs of the type often have elaborate corbelled roofs rather than simple slabs. Megalithic art has been identified carved into the stones at some sites and this appears to be one of the first uses of the term passage tomb. It is likely that the writers borrowed from the Spanish term tumbas de corredor, which is used for tombs in Cantabria, Galicia, of their list, only passage tombs appear to have widespread distribution throughout Europe. Passage graves are distributed extensively in lands along the Atlantic seaboard of Europe and they are found in Ireland, Britain, Scandinavia, northern Germany and the Drenthe area of the Netherlands. They are also found in Iberia, some parts of the Mediterranean, the earliest passage tombs seem to take the form of small dolmens. In Ireland and Britain, passage tombs are found in large clusters. Many later passage tombs were constructed at the tops of hills or mountains, Newgrange. com World Heritage IE - Newgrange, Knowth and Dowth
