Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Greece
–
Greece, officially the Hellenic Republic, historically also known as Hellas, is a country in southeastern Europe, with a population of approximately 11 million as of 2015. Athens is the capital and largest city, followed by Thessaloniki. Greece is strategically located at the crossroads of Europe, Asia, situated on the southern tip of the Balkan peninsula, it shares land borders with Albania to the northwest, the Republic of Macedonia and Bulgaria to the north, and Turkey to the northeast. Greece consists of nine regions, Macedonia, Central Greece, the Peloponnese, Thessaly, Epirus, the Aegean Islands, Thrace, Crete. The Aegean Sea lies to the east of the mainland, the Ionian Sea to the west, the Cretan Sea and the Mediterranean Sea to the south. Greece has the longest coastline on the Mediterranean Basin and the 11th longest coastline in the world at 13,676 km in length, featuring a vast number of islands, eighty percent of Greece is mountainous, with Mount Olympus being the highest peak at 2,918 metres. From the eighth century BC, the Greeks were organised into various independent city-states, known as polis, which spanned the entire Mediterranean region and the Black Sea. Greece was annexed by Rome in the second century BC, becoming a part of the Roman Empire and its successor. The Greek Orthodox Church also shaped modern Greek identity and transmitted Greek traditions to the wider Orthodox World, falling under Ottoman dominion in the mid-15th century, the modern nation state of Greece emerged in 1830 following a war of independence. Greeces rich historical legacy is reflected by its 18 UNESCO World Heritage Sites, among the most in Europe, Greece is a democratic and developed country with an advanced high-income economy, a high quality of life, and a very high standard of living. A founding member of the United Nations, Greece was the member to join the European Communities and has been part of the Eurozone since 2001. Greeces unique cultural heritage, large industry, prominent shipping sector. It is the largest economy in the Balkans, where it is an important regional investor, the names for the nation of Greece and the Greek people differ from the names used in other languages, locations and cultures. The earliest evidence of the presence of human ancestors in the southern Balkans, dated to 270,000 BC, is to be found in the Petralona cave, all three stages of the stone age are represented in Greece, for example in the Franchthi Cave. Neolithic settlements in Greece, dating from the 7th millennium BC, are the oldest in Europe by several centuries and these civilizations possessed writing, the Minoans writing in an undeciphered script known as Linear A, and the Mycenaeans in Linear B, an early form of Greek. The Mycenaeans gradually absorbed the Minoans, but collapsed violently around 1200 BC and this ushered in a period known as the Greek Dark Ages, from which written records are absent. The end of the Dark Ages is traditionally dated to 776 BC, the Iliad and the Odyssey, the foundational texts of Western literature, are believed to have been composed by Homer in the 7th or 8th centuries BC. With the end of the Dark Ages, there emerged various kingdoms and city-states across the Greek peninsula, in 508 BC, Cleisthenes instituted the worlds first democratic system of government in Athens

Modern regions of Greece
–
The administrative regions of Greece are the countrys thirteen first-level administrative entities, each comprising several second-level units, originally prefectures and, since 2011, regional units. The current regions were established in July 1986, by decision of then-Interior Minister Menios Koutsogiorgas as a second-level administrative entities, as part of a decentralization process inspired by then-Interior Minister Alekos Papadopoulos, they were accorded more powers in the 1997 Kapodistrias reform of local and regional government. They were transformed into separate entities by the 2010 Kallikratis Plan. In the 2011 changes, the general secretary was replaced with a popularly elected regional governor. Many powers of the prefectures, which were abolished or reformed into regional units, were transferred to the region level. The regional organs of the government were in turn replaced by seven decentralized administrations. Bordering the region of Central Macedonia there is one region, Mount Athos. It is located on the easternmost of the three large peninsulas jutting into the Aegean from the Chalcidice Peninsula, ISO 3166-2, GR Administrative divisions of Greece

The South Aegean is one of the thirteen regions of Greece. It consists of the Cyclades and Dodecanese island groups in the central, the South Aegean region was established in the 1987 administrative reform. With the 2010 Kallikratis plan, its powers and authority were redefined and extended, along with the Northern Aegean region, it is supervised by the Decentralized Administration of the Aegean based at Piraeus. The capital of the region is situated in Ermoupoli on the island of Syros, until the Kallikratis reform, the region consisted of the two prefectures of the Cyclades and the Dodecanese.

Andros, also called Chora, is a town and a former municipality on the island of Andros, in the Cyclades, Greece. Since the 2011 local government reform it is part of the municipality Andros, of which it is a municipal unit, the municipal unit has an area of 102.756 km2. Its population was 3,901 inhabitants at the 2011 census and it has a mix of post-World War I neoclassical mansions with vernacular Cycladic houses. The town squares are paved with marble, at the end of the headland are two islands. The first, linked to the mainland by a bridge, with a ruined Venetian castle. There are four museums, the extensive Archaeological Museum, Museum of Modern Art, a Nautical Museum and a Folklore Museum

Vehicle registration plates of Greece
–
Greek vehicle registration plates are composed of three letters and four digits per plate. The letters represent the district that issues the plates while the numbers begin from 1000 to 9999, similar plates with digits beginning from 1 to 999 are issued for motorcycles which exceed 50 cc. With the exception of Athens and Thessaloniki, all districts are represented by the first 2 letters, the final letter in the sequence changes in Greek alphabetical order after 9,000 issued plates. For example, Patras plates are ΑΧΑ-1000, where ΑΧ represents the Achaia prefecture of which Patras is the capital, when ΑΧΑ-9999 is reached the plates turn to ΑΧΒ-1000 and this continues until ΑΧΧ is finished. Only the letters from the intersection between the Latin and Greek alphabets by glyph appearance are used, namely Α, Β, Ε, Ζ, Η, Ι, Κ, Μ, Ν, Ο, Ρ, Τ, Υ, Χ. This is because Greece is a party to the Vienna Convention on Road Traffic. The rule applies in a way in Russia, Ukraine, Belarus, Bosnia and Herzegovina. Combinations used for residents are L-NNNN and are limited. Until 2003, taxis used L-NNNN, the plate was aligned with the prefecture, when number plates were introduced to Greece, they were numbered and in the late 1950s the system was L-NNN and LL-NNN. The letters were Greek letters and Latin letters, respectively, in 1956, the system was NNNNNN. In 1972, they became lettered and the system was LL-NNNN while trucks used L-NNNN, in 1983, the system was LLL-NNNN and the first two letters are prefecture letters. In 2004, the euroband was added, the first 2 of 3 letters of a licence plate usually represent the prefecture where the car was registered.

Greek language
–
Greek is an independent branch of the Indo-European family of languages, native to Greece and other parts of the Eastern Mediterranean. It has the longest documented history of any living language, spanning 34 centuries of written records and its writing system has been the Greek alphabet for the major part of its history, other systems, such as Linear B and the Cypriot syllabary, were used previously. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic and many other writing systems. Together with the Latin texts and traditions of the Roman world, during antiquity, Greek was a widely spoken lingua franca in the Mediterranean world and many places beyond. It would eventually become the official parlance of the Byzantine Empire, the language is spoken by at least 13.2 million people today in Greece, Cyprus, Italy, Albania, Turkey, and the Greek diaspora. Greek roots are used to coin new words for other languages, Greek. Greek has been spoken in the Balkan peninsula since around the 3rd millennium BC, the earliest written evidence is a Linear B clay tablet found in Messenia that dates to between 1450 and 1350 BC, making Greek the worlds oldest recorded living language. Among the Indo-European languages, its date of earliest written attestation is matched only by the now extinct Anatolian languages, the Greek language is conventionally divided into the following periods, Proto-Greek, the unrecorded but assumed last ancestor of all known varieties of Greek. The unity of Proto-Greek would have ended as Hellenic migrants entered the Greek peninsula sometime in the Neolithic era or the Bronze Age, Mycenaean Greek, the language of the Mycenaean civilisation. It is recorded in the Linear B script on tablets dating from the 15th century BC onwards, Ancient Greek, in its various dialects, the language of the Archaic and Classical periods of the ancient Greek civilisation. It was widely known throughout the Roman Empire, after the Roman conquest of Greece, an unofficial bilingualism of Greek and Latin was established in the city of Rome and Koine Greek became a first or second language in the Roman Empire. The origin of Christianity can also be traced through Koine Greek, Medieval Greek, also known as Byzantine Greek, the continuation of Koine Greek in Byzantine Greece, up to the demise of the Byzantine Empire in the 15th century. Much of the written Greek that was used as the language of the Byzantine Empire was an eclectic middle-ground variety based on the tradition of written Koine. Modern Greek, Stemming from Medieval Greek, Modern Greek usages can be traced in the Byzantine period and it is the language used by the modern Greeks, and, apart from Standard Modern Greek, there are several dialects of it. In the modern era, the Greek language entered a state of diglossia, the historical unity and continuing identity between the various stages of the Greek language is often emphasised. Greek speakers today still tend to regard literary works of ancient Greek as part of their own rather than a foreign language and it is also often stated that the historical changes have been relatively slight compared with some other languages. According to one estimation, Homeric Greek is probably closer to demotic than 12-century Middle English is to modern spoken English, Greek is spoken by about 13 million people, mainly in Greece, Albania and Cyprus, but also worldwide by the large Greek diaspora. Greek is the language of Greece, where it is spoken by almost the entire population

Island
–
An island or isle is any piece of sub-continental land that is surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, an island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. A grouping of geographically or geologically related islands is called an archipelago, an island may be described as such, despite the presence of an artificial land bridge, examples are Singapore and its causeway, and the various Dutch delta islands, such as IJsselmonde. There are two types of islands in the sea, continental and oceanic. The word island derives from Middle English iland, from Old English igland, Old English ieg is actually a cognate of Swedish ö and German Aue, and related to Latin aqua. There is a difference between islands and continents in terms of geology, continents sit on continental lithosphere which is part of tectonic plates floating high on Earths mantle. Oceanic crust is also part of tectonic plates, but it is denser than continental lithosphere, Islands are either extensions of the oceanic crust or geologically they are part of some continent sitting on continental lithosphere. This holds true for Australia, which sits on its own continental lithosphere, continental islands are bodies of land that lie on the continental shelf of a continent. A special type of island is the microcontinental island, which is created when a continent is rifted. Examples are Madagascar and Socotra off Africa, the Kerguelen Islands, New Caledonia, New Zealand, another subtype is an island or bar formed by deposition of tiny rocks where water current loses some of its carrying capacity. While some are transitory and may disappear if the volume or speed of the current changes, others are stable, oceanic islands are islands that do not sit on continental shelves. The vast majority are volcanic in origin, such as Saint Helena in the South Atlantic Ocean, the few oceanic islands that are not volcanic are tectonic in origin and arise where plate movements have lifted up the ocean floor above the surface. Examples are Saint Peter and Paul Rocks in the Atlantic Ocean, one type of volcanic oceanic island is found in a volcanic island arc. These islands arise from volcanoes where the subduction of one plate under another is occurring, examples are the Aleutian Islands, the Mariana Islands, and most of Tonga in the Pacific Ocean. The only examples in the Atlantic Ocean are some of the Lesser Antilles, another type of volcanic oceanic island occurs where an oceanic rift reaches the surface. There are two examples, Iceland, which is the second largest volcanic island, and Jan Mayen. A third type of oceanic island is formed over volcanic hotspots. A hotspot is more or less stationary relative to the tectonic plate above it

Cyclades
–
The Cyclades are an island group in the Aegean Sea, southeast of mainland Greece and a former administrative prefecture of Greece. They are one of the groups which constitute the Aegean archipelago. The name refers to the islands around the island of Delos. The Cyclades is where the native Greek breed of cat originated, the largest island of the Cyclades is Naxos. Interest lagged, then picked up in the century, as collectors competed for the modern-looking figures that seemed so similar to sculpture by Jean Arp or Constantin Brâncuși. Sites were looted and a trade in forgeries arose. The context for many of these Cycladic figurines has been mostly destroyed, another intriguing and mysterious object is that of the Cycladic frying pans. More accurate archaeology has revealed the outlines of a farming and seafaring culture that had immigrated from Anatolia c.5000 BCE. Early Cycladic culture evolved in three phases, between c.3300 –2000 BCE, when it was swamped in the rising influence of Minoan Crete. The culture of mainland Greece contemporary with Cycladic culture is known as the Helladic period, in recent decades the Cyclades have become popular with European and other tourists, and as a result there have been problems with erosion, pollution, and water shortages. There are also many islands including Donousa, Eschati, Gyaros, Irakleia, Koufonisia, Makronisos. The name Cyclades refers to the forming a circle around the sacred island of Delos. Most of the islands are uninhabited. Ermoupoli on Syros is the town and administrative center of the former prefecture. The islands are peaks of a mountainous terrain, with the exception of two volcanic islands, Milos and Santorini. The climate is dry and mild, but with the exception of Naxos the soil is not very fertile, agricultural produce includes wine, fruit, wheat, olive oil. Cooler temperatures are in higher elevations and mainly do not receive wintry weather, the Cyclades are bounded to the south by the Sea of Crete. The Cyclades Prefecture was one of the prefectures of Greece and these have been reorganised at the 2011 Kallikratis reform as well

Archipelago
–
An archipelago, sometimes called an island group or island chain, is a chain, cluster or collection of islands. The word archipelago is derived from the Greek ἄρχι- – arkhi-, in Italian, possibly following a tradition of antiquity, the Archipelago was the proper name for the Aegean Sea and, later, usage shifted to refer to the Aegean Islands. It is now used to refer to any group or, sometimes. Archipelagos may be isolated in large amounts of water or neighbouring a large land mass. For example, Scotland has more than 700 islands surrounding its mainland which form an archipelago, archipelagos are often volcanic, forming along island arcs generated by subduction zones or hotspots, but may also be the result of erosion, deposition, and land elevation. Depending on their origin, islands forming archipelagos can be referred to as oceanic islands, continental fragments. Oceanic islands are mainly of volcanic origin, continental fragments correspond to land masses that have separated from a continental mass due to tectonic displacement. Indonesia, Japan, Taiwan, the Philippines, New Zealand, Maldives, the Bahamas, Greece, Hawaii, the largest archipelagic state in the world by area and population is Indonesia.

Mountain
–
A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is steeper than a hill. Mountains are formed through tectonic forces or volcanism and these forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, a few mountains are isolated summits, but most occur in huge mountain ranges. High elevations on mountains produce colder climates than at sea level and these colder climates strongly affect the ecosystems of mountains, different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction and recreation, the highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,850 m above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m, there is no universally accepted definition of a mountain. Elevation, volume, relief, steepness, spacing and continuity have been used as criteria for defining a mountain, whether a landform is called a mountain may depend on local usage. The highest point in San Francisco, California, is called Mount Davidson, notwithstanding its height of 300 m, similarly, Mount Scott outside Lawton, Oklahoma is only 251 m from its base to its highest point. Whittows Dictionary of Physical Geography states Some authorities regard eminences above 600 metres as mountains, in addition, some definitions also include a topographical prominence requirement, typically 100 or 500 feet. For a while, the US defined a mountain as being 1,000 feet or taller, any similar landform lower than this height was considered a hill. However, today, the United States Geological Survey concludes that these terms do not have technical definitions in the US, using these definitions, mountains cover 33% of Eurasia, 19% of South America, 24% of North America, and 14% of Africa. As a whole, 24% of the Earths land mass is mountainous, there are three main types of mountains, volcanic, fold, and block. All three types are formed from plate tectonics, when portions of the Earths crust move, crumple, compressional forces, isostatic uplift and intrusion of igneous matter forces surface rock upward, creating a landform higher than the surrounding features. The height of the feature makes it either a hill or, if higher and steeper, major mountains tend to occur in long linear arcs, indicating tectonic plate boundaries and activity. Volcanoes are formed when a plate is pushed below another plate, at a depth of around 100 km, melting occurs in rock above the slab, and forms magma that reaches the surface. When the magma reaches the surface, it builds a volcanic mountain. Examples of volcanoes include Mount Fuji in Japan and Mount Pinatubo in the Philippines, the magma does not have to reach the surface in order to create a mountain, magma that solidifies below ground can still form dome mountains, such as Navajo Mountain in the US

Valley
–
A valley is a low area between hills, often with a river running through it. In geology, a valley or dale is a depression that is longer than it is wide, the terms U-shaped and V-shaped are descriptive terms of geography to characterize the form of valleys. Most valleys belong to one of two main types or a mixture of them, with respect to the cross section of the slopes or hillsides. A valley in its broadest geographic sense is known as a dale. A valley through which a river runs may also be referred to as a vale, a small, secluded, and often wooded valley is known as a dell or in Scotland as a glen. A wide, flat valley through which a river runs is known in Scotland as a strath, a mountain cove is a small valley, closed at one or both ends, in the central or southern Appalachian Mountains which sometimes results from the erosion of a geologic window. A small valley surrounded by mountains or ridges is sometimes known as a hollow, a deep, narrow valley is known as a cwm. Similar geological structures, such as canyons, ravines, gorges, gullies, chines, a valley formed by erosion is called an erosional valley, a valley formed by geologic events such as drop faults or the rise of highlands is called a structural valley. A valley formed by flowing water, or river valley, is usually V-shaped, the exact shape will depend on the characteristics of the stream flowing through it. Rivers with steep gradients, as in mountain ranges, produce steep walls, shallower slopes may produce broader and gentler valleys. However, in the lowest stretch of a river, where it approaches its base level, it begins to deposit sediment, in prehistory, the rivers were used as a source of fresh water and food, as well as a place to wash and a sewer. The proximity of water moderated temperature extremes and provided a source for irrigation, most of the first civilizations developed from these river valley communities. In geography, a vale is a river valley, usually with a particularly wide flood plain or flat valley bottom. In Southern England, vales commonly occur between the escarpment slopes of pairs of chalk formations, where the dome has been eroded, exposing less resistant underlying rock. Rift valleys, such as the Albertine Rift, are formed by the expansion of the Earths crust due to tectonic activity beneath the Earths surface, there are various forms of valley associated with glaciation that may be referred to as glacial valleys. A valley carved by glaciers is normally U-shaped, the valley becomes visible upon the recession of the glacier that forms it. When the ice recedes or thaws, the remains, often littered with small boulders that were transported within the ice. Floor gradient does not affect the shape, it is the glaciers size that does

Breakwater (structure)
–
Breakwaters are structures constructed on coasts as part of coastal defense or to protect an anchorage from the effects of both weather and longshore drift. Breakwaters reduce the intensity of wave action in inshore waters and thereby reduce coastal erosion or provide safe harbourage, Breakwaters may also be small structures designed to protect a gently sloping beach and put one to three hundred thousand feet onshore in relatively shallow water. An anchorage is only safe if ships anchored there are protected from the force of high winds, natural harbours are formed by such barriers as headlands or reefs. Artificial harbours can be created with the help of breakwaters, mobile harbours, such as the D-Day Mulberry harbours, were floated into position and acted as breakwaters. Some natural harbours, such as those in Plymouth Sound, Portland Harbour, the dissipation of energy and relative calm water created in the lee of the breakwaters often encourage accretion of sediment. However, this can lead to excessive salient build up, resulting in tombolo formation and this trapping of sediment can cause adverse effects down-drift of the breakwaters, leading to beach sediment starvation and increased erosion. This may then lead to further engineering protection being needed down-drift of the breakwater development, Breakwaters are subject to damage, and overtopping in severe storms events. Breakwaters can be constructed with one end linked to the shore, length of gap is largely governed by the interacting wavelengths. Breakwaters may be fixed or floating, and impermeable or permeable to allow sediment transfer shoreward of the structures. They usually consist of pieces of rock weighing up to 16 tonnes each. Their design is influenced by the angle of approach and other environmental parameters. Breakwater construction can be parallel or perpendicular to the coast. Of these three, the angle at which the breakwater is built is most important in the formation of salients. The angle at which the breakwater is built determines the new direction of the waves, a breakwater structure is designed to absorb the energy of the waves that hit it, either by using mass, or by using a revetment slope. In coastal engineering, a revetment is a land backed structure whilst a breakwater is a sea backed structure, caisson breakwaters typically have vertical sides and are usually erected where it is desirable to berth one or more vessels on the inner face of the breakwater. They use the mass of the caisson and the fill within it to resist the forces applied by waves hitting them. They are relatively expensive to construct in shallow water, but in deeper sites they can offer a significant saving over revetment breakwaters, rubble mound breakwaters use structural voids to dissipate the wave energy. Rock or concrete armour units on the outside of the structure absorb most of the energy, the slopes of the revetment are typically between 1,1 and 1,2, depending upon the materials used

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

Cycladic culture
–
Cycladic civilization is an Early Bronze Age culture of the Cyclades, Greece, in the Aegean Sea, spanning the period from approximately 3200–2000 BC. These figures have been stolen from burials to satisfy the Cycladic antiquities market since the early 20th century, only about 40% of the 1,400 figurines found are of known origin, since looters destroyed evidence of the rest. Excavated sites include Saliagos and Kephala, which showed signs of copper-working, each of the small Cycladic islands could support no more than a few thousand people, though Late Cycladic boat models show that fifty oarsmen could be assembled from the scattered communities. The chronology of Cycladic civilization is divided into three sequences, Early, Middle and Late Cycladic. The early period, beginning c.3000 BC segued into the archaeologically murkier Middle Cycladic c.2500 BC, by the end of the Late Cycladic sequence there was essential convergence between Cycladic and Minoan civilization. There is some tension between the systems used for Cycladic civilization, one cultural and one chronological. Interest then lagged, but picked up in the mid-20th century, sites were looted and a brisk trade in forgeries arose. The context for many of these Cycladic Figurines has thus been mostly destroyed, another intriguing and mysterious object is that of the Cycladic frying pans. Early Cycladic culture evolved in three phases, between c.3300 and 2000 BC, when it was submerged in the rising influence of Minoan Crete. Excavations at Knossos on Crete reveal an influence of Cycladic civilization upon Knossos in the period 3400 to 2000 BC as evidenced from pottery finds at Knossos, Cycladic art Goulandris Museum of Cycladic Art History of the Cyclades

Bronze Age
–
The Bronze Age is a historical period characterized by the use of bronze, proto-writing, and other early features of urban civilization. The Bronze Age is the principal period of the three-age Stone-Bronze-Iron system, as proposed in modern times by Christian Jürgensen Thomsen. An ancient civilization is defined to be in the Bronze Age either by smelting its own copper and alloying with tin, arsenic, or other metals, or by trading for bronze from production areas elsewhere. Copper-tin ores are rare, as reflected in the fact there were no tin bronzes in Western Asia before trading in bronze began in the third millennium BC. Worldwide, the Bronze Age generally followed the Neolithic period, with the Chalcolithic serving as a transition, although the Iron Age generally followed the Bronze Age, in some areas, the Iron Age intruded directly on the Neolithic. Bronze Age cultures differed in their development of the first writing, according to archaeological evidence, cultures in Mesopotamia and Egypt developed the earliest viable writing systems. The overall period is characterized by use of bronze, though the place and time of the introduction. Human-made tin bronze technology requires set production techniques, tin must be mined and smelted separately, then added to molten copper to make bronze alloy. The Bronze Age was a time of use of metals. The dating of the foil has been disputed, the Bronze Age in the ancient Near East began with the rise of Sumer in the 4th millennium BC. Societies in the region laid the foundations for astronomy and mathematics, the usual tripartite division into an Early, Middle and Late Bronze Age is not used. Instead, a division based on art-historical and historical characteristics is more common. The cities of the Ancient Near East housed several tens of thousands of people, ur in the Middle Bronze Age and Babylon in the Late Bronze Age similarly had large populations. The earliest mention of Babylonia appears on a tablet from the reign of Sargon of Akkad in the 23rd century BC, the Amorite dynasty established the city-state of Babylon in the 19th century BC. Over 100 years later, it took over the other city-states. Babylonia adopted the written Semitic Akkadian language for official use, by that time, the Sumerian language was no longer spoken, but was still in religious use. Elam was an ancient civilization located to the east of Mesopotamia, in the Old Elamite period, Elam consisted of kingdoms on the Iranian plateau, centered in Anshan, and from the mid-2nd millennium BC, it was centered in Susa in the Khuzestan lowlands. Its culture played a role in the Gutian Empire and especially during the Achaemenid dynasty that succeeded it

Seaport
–
A port is a location on a coast or shore containing one or more harbors where ships can dock and transfer people or cargo to or from land. Port locations are selected to optimize access to land and navigable water, for commercial demand, Ports with deeper water are rarer, but can handle larger ships. Since ports throughout history handled every kind of traffic, support and storage facilities vary widely, may extend for miles, some ports have an important military role. One of the worlds oldest known artificial harbors is at Wadi al-Jarf on the Red Sea, along with the finding of harbor structures, ancient anchors have also been found. Guangzhou was an important port during the ancient times as far back as the Qin Dynasty, canopus was the principal port in Egypt for Greek trade before the foundation of Alexandria. Athens port of Piraeus was the base for the Athenian fleet, lothal is one of the most prominent cities of the ancient Indus valley civilisation, located in the Bhāl region of the modern state of Gujarāt and dating from 3700 BCE. Ostia Antica was the port of ancient Rome with Portus established by Claudius, Ports often have cargo-handling equipment, such as cranes and forklifts for use in loading ships, which may be provided by private interests or public bodies. Often, canneries or other processing facilities will be located nearby, some ports feature canals, which allow ships further movement inland. Access to intermodal transportation, such as railroads and highways, is critical to a port, so that passengers, Ports with international traffic have customs facilities. Harbor pilots and tugboats may maneuver large ships in tight quarters when near docks, the terms port and seaport are used for different types of port facilities that handle ocean-going vessels, and river port is used for river traffic, such as barges and other shallow-draft vessels. An inland port is a port on a lake, river, or canal with access to a sea or ocean. An example of this is the St. Lawrence Seaway which allows ships to travel from the Atlantic Ocean several thousand kilometers inland to Great Lakes ports like Duluth-Superior, a fishing port is a port or harbor for landing and distributing fish. It may be a facility, but it is usually commercial. A fishing port is the port that depends on an ocean product. In recent decades, regulations to save fishing stock may limit the use of a fishing port, a dry port is an inland intermodal terminal directly connected by road or rail to a seaport and operating as a centre for the transshipment of sea cargo to inland destinations. A warm-water port is one where the water does not freeze in wintertime, because they are available year-round, warm-water ports can be of great geopolitical or economic interest. A seaport is further categorized as a port or a cargo port. Additionally, cruise ports are known as a home port or a port of call

Jackals
–
Jackals are medium-sized omnivorous mammals of the genus Canis, which also includes wolves and the domestic dog. Jackals and coyotes are opportunistic omnivores, predators of small- to medium-sized animals, Jackals are crepuscular, most active at dawn and dusk. The territory may be enough to hold some young adults. Jackals may occasionally assemble in small packs, for example, to scavenge a carcass, the English word jackal derives from Persian شغال shoghāl, cognate with Sanskrit सृगालः / sṛgālaḥ. The taxonomy of the jackals has evolved with scientific understanding about how they are related on the family tree. In practice, Cabrera chose the alternative and referred to the jackals as Canis instead of Thos. Okens Thos theory was revived in 1914 by Edmund Heller, who embraced the separate genus theory, hellers names and the designations he gave to various jackal species and subspecies live on in current taxonomy, although the genus has been changed from Thos to Canis. Modern research has clarified the relationships among the jackal species, despite their similarities, jackals do not all stem from the same branch on the canid family tree. Because of this deep divergence between the black-backed/side-striped jackal and the jackal, it has been proposed to change the two species generic name from Canis to Lupulella. Experiments in Germany with breeding poodles and golden jackals have produced hybrids, in Russia, golden jackals are one of the founder breeds of the Sulimov dog, a working dog owned exclusively by Aeroflot and used for bomb detection in airport security. Like foxes and coyotes, jackals are often depicted as clever sorcerers in the myths, anubis is the Greek name for a jackal-headed god associated with mummification and the afterlife in ancient Egyptian religion. The jackal is mentioned approximately 14 times in the Bible and it is called wild dog in several translations of the Bible. Serer religion and creation myth posits the jackal was among the first animals created by Roog, pablo Nerudas poem I Explain a Few Things describes Francisco Franco and his allies as. Jackals that the jackal would drive off. In Rudyard Kiplings collection of stories The Jungle Book, the mad cowardly jackal Tabaqui feasts on the scraps of Shere Khan, in the King James translation of the Bible, Isaiah 13,21 refers to doleful creatures, which some commentators suggest are either jackals or hyenas. Literature in India and Pakistan compares jackal with lion in terms of courage, a famous saying is One day life of a lion is better than a hundred years life of a jackal. Multiple jackals are featured throughout the Swiss Family Robinson.

Goats
–
The domestic goat is a subspecies of goat domesticated from the wild goat of southwest Asia and Eastern Europe. The goat is a member of the family Bovidae and is related to the sheep as both are in the goat-antelope subfamily Caprinae. There are over 300 distinct breeds of goat, Goats are one of the oldest domesticated species, and have been used for their milk, meat, hair, and skins over much of the world. In 2011, there were more than 924 million live goats around the globe, according to the UN Food, female goats are referred to as does or nannies, intact males are called bucks or billies, and juveniles of both sexes are called kids. Goat meat from animals is called kid or cabrito, while meat from older animals is known simply as goat or sometimes called chevon. To refer to the male, Old English used bucca until ousted by hegote, hegoote in the late 12th century, nanny goat originated in the 18th century and billy goat in the 19th. Goats are among the earliest animals domesticated by humans, the most recent genetic analysis confirms the archaeological evidence that the wild Bezoar ibex of the Zagros Mountains is the likely original ancestor of probably all domestic goats today. The earliest remnants of domesticated goats dating 10,000 years before present are found in Ganj Dareh in Iran. Goat remains have been found at sites in Jericho, Choga Mami Djeitun and Çayönü. Studies of DNA evidence suggests 10,000 years BP as the domestication date, historically, goat hide has been used for water and wine bottles in both traveling and transporting wine for sale. It has also used to produce parchment. Goats are considered small livestock animals, compared to animals such as cattle, camels and horses, but larger than microlivestock such as poultry, rabbits, cavies. Each recognized breed of goats has specific weight ranges, which vary from over 140 kg for bucks of larger breeds such as the Boer, within each breed, different strains or bloodlines may have different recognized sizes. At the bottom of the range are miniature breeds such as the African Pygmy. Most goats naturally have two horns, of various shapes and sizes depending on the breed, Goats have horns unless they are polled or the horns have been removed, typically soon after birth. There have been incidents of polycerate goats, although this is a genetic rarity thought to be inherited, the horns are most typically removed in commercial dairy goat herds, to reduce the injuries to humans and other goats. Unlike cattle, goats have not been bred to be reliably polled, as the genes determining sex. Breeding together two genetically polled goats results in a number of intersex individuals among the offspring, which are typically sterile

Deer

Deer are the ruminant mammals forming the family Cervidae. The two main groups are the Cervinae, including the muntjac, the deer and the chital, and the Capreolinae, including the elk, reindeer, the Western roe deer. Female reindeer, and male deer of all species, grow, in this they differ from permanently horned antelope, which are in the same order, Artiodactyla. The musk deer of Asia and water chevrotain of tropical African and Asian forests are not usually regarded as true deer and form their own families, Moschidae and Tragulidae, respectively. Deer appear in art from Palaeolithic cave paintings onwards, and they have played a role in mythology, religion and their economic importance includes the use of their meat as venison, their skins as soft, strong buckskin, and their antlers as handles for knives. Deer hunting has been a sport since at least the Middle Ages. Deer live in a variety of biomes, ranging from tundra to the tropical rainforest, while often associated with forests, many deer are ecotone species that live in transitional areas between forests and thickets and prairie and savanna. The majority of deer species inhabit temperate mixed deciduous forest, mountain mixed coniferous forest, tropical seasonal/dry forest. Clearing open areas within forests to some extent may actually benefit deer populations by exposing the understory and allowing the types of grasses, weeds, additionally, access to adjacent croplands may also benefit deer. However, adequate forest or brush cover must still be provided for populations to grow, however, fallow deer have been introduced to South Africa. There are also species of deer that are highly specialized, and live almost exclusively in mountains, grasslands, swamps. Some deer have a distribution in both North America and Eurasia. Examples include the caribou that live in Arctic tundra and taiga and moose that inhabit taiga, huemul deer of South Americas Andes fill the ecological niches of the ibex and wild goat, with the fawns behaving more like goat kids. Mountain slope habitats vary from moist coniferous/mixed forested habitats to dry forests with alpine meadows higher up. The foothills and river valleys between the mountain provide a mosaic of cropland and deciduous parklands. The rare woodland caribou have the most restricted range living at altitudes in the subalpine meadows. Elk and mule deer both migrate between the alpine meadows and lower coniferous forests and tend to be most common in this region, elk also inhabit river valley bottomlands, which they share with White-tailed deer. They also live in the aspen parklands north of Calgary and Edmonton, the adjacent Great Plains grassland habitats are left to herds of elk, American bison, and pronghorn antelope

Fish
–
A fish is any member of a group of animals that consist of all gill-bearing aquatic craniate animals that lack limbs with digits. They form a group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous, tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered obsolete or paraphyletic by excluding the tetrapods, because in this manner the term fish is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology. The traditional term pisces is considered a typological, but not a phylogenetic classification, the earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts, fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators, the first fish with jaws appeared in the Silurian period, after which many became formidable marine predators rather than just the prey of arthropods. Fish are abundant in most bodies of water and they can be found in nearly all aquatic environments, from high mountain streams to the abyssal and even hadal depths of the deepest oceans. With 33,100 described species, fish exhibit greater species diversity than any group of vertebrates. Fish are an important resource for humans worldwide, especially as food, commercial and subsistence fishers hunt fish in wild fisheries or farm them in ponds or in cages in the ocean. They are also caught by fishers, kept as pets, raised by fishkeepers. Fish have had a role in culture through the ages, serving as deities, religious symbols, fish do not represent a monophyletic group, and therefore the evolution of fish is not studied as a single event. Early fish from the record are represented by a group of small, jawless. Jawless fish lineages are mostly extinct, an extant clade, the lampreys may approximate ancient pre-jawed fish. The first jaws are found in Placodermi fossils, the diversity of jawed vertebrates may indicate the evolutionary advantage of a jawed mouth. It is unclear if the advantage of a hinged jaw is greater biting force, improved respiration, fish may have evolved from a creature similar to a coral-like sea squirt, whose larvae resemble primitive fish in important ways. The first ancestors of fish may have kept the form into adulthood. Fish are a group, that is, any clade containing all fish also contains the tetrapods

Dolphins
–
Dolphins are a widely distributed and diverse group of aquatic mammals. They are a grouping within the order Cetacea, excluding whales and porpoises. The dolphins comprise the extant families Delphinidae, Platanistidae, Iniidae, and Pontoporiidae, there are 40 extant species of dolphins. Dolphins, alongside other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates and their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. Dolphins range in size from the 1.7 m long and 50 kg Mauis dolphin to the 9.5 m and 10 t killer whale, several species exhibit sexual dimorphism, in that the males are larger than females. They have streamlined bodies and two limbs that are modified into flippers, though not quite as flexible as seals, some dolphins can travel at 55.5 km/h. Dolphins use their conical shaped teeth to capture fast moving prey and they have well-developed hearing which is adapted for both air and water and is so well developed that some can survive even if they are blind. Some species are adapted for diving to great depths. They have a layer of fat, or blubber, under the skin to keep warm in the cold water, although dolphins are widespread, most species prefer the warmer waters of the tropic zones, but some, like the right whale dolphin, prefer colder climates. Dolphins feed largely on fish and squid, but a few, like the killer whale, feed on large mammals, male dolphins typically mate with multiple females every year, but females only mate every two to three years. Calves are typically born in the spring and summer months and females bear all the responsibility for raising them, mothers of some species fast and nurse their young for a relatively long period of time. Dolphins produce a variety of vocalizations, usually in the form of clicks, Dolphins are sometimes hunted in places like Japan, in an activity known as dolphin drive hunting. Besides drive hunting, they face threats from bycatch, habitat loss. Dolphins have been depicted in cultures worldwide. Dolphins occasionally feature in literature and film, as in the film series Free Willy, Dolphins are sometimes kept in captivity and trained to perform tricks, but breeding success has been poor and the animals often die within a few months of capture. The most common dolphins kept are killer whales and bottlenose dolphins, the name is originally from Greek δελφίς, dolphin, which was related to the Greek δελφύς, womb. The animals name can therefore be interpreted as meaning a fish with a womb, the name was transmitted via the Latin delphinus, which in Medieval Latin became dolfinus and in Old French daulphin, which reintroduced the ph into the word. The term mereswine has also historically been used, the term dolphin can be used to refer to, under the parvorder Odontoceti, all the species in the family Delphinidae and the river dolphin families Iniidae, Pontoporiidae, Lipotidae and Platanistidae

Flotilla
–
A flotilla, or naval flotilla, is a formation of small warships that may be part of a larger fleet. A flotilla is usually composed of a group of the same class of warship, such as frigates, destroyers, torpedo boats, submarines, gunboats. Groups of larger warships are usually called squadrons, but similar units of non-capital ships may be called squadrons in some instances, a flotilla is usually commanded by a rear admiral, a commodore or a captain, depending on the importance of the command. A flotilla is often divided into two or more divisions, each of which might be commanded by the most senior commander, a flotilla is often, but not necessarily, a permanent formation. In modern navies, flotillas have tended to become administrative units containing several squadrons, as warships have grown larger, the term squadron has gradually replaced the term flotilla for formations of destroyers, frigates and submarines in many navies. A naval flotilla has no equivalent on land, but is, perhaps. In the United States Coast Guard Auxiliary, a Flotilla is the organizational unit. A Flotilla is led by an elected Flotilla Commander assisted by an elected Vice Flotilla Commander, a Coast Guard Auxiliary Division consists of multiple Flotillas and a District consists of multiple Divisions. Auxiliary Districts are organized along Coast Guard District lines and are administered by a Coast Guard officer who is called the Director of the Auxiliary. In the Russian Navy, the flotilla has tended to be used for brown-water naval units - those operating not on the oceans and real seas. In the 18th century, the term applied to the comparatively small fleets operating on those seas where Russia did not have much naval presence yet. The word flotilla has also used at times to refer to a small fleet of vessels. There is also such thing as a holiday, in which is a group of chartered yachts that set sail together on the same route.

Ionia
–
Ionia is an ancient region of central coastal Anatolia in present-day Turkey, the region nearest İzmir, which was historically Smyrna. It consisted of the northernmost territories of the Ionian League of Greek settlements, never a unified state, it was named after the Ionian tribe who, in the Archaic Period, settled mainly the shores and islands of the Aegean Sea. Ionian states were identified by tradition and by their use of Eastern Greek and it was bounded by Aeolia to the north, Lydia to the east and Caria to the south. The cities within the region figured large in the strife between the Persian Empire and the Greeks, according to Greek tradition, the cities of Ionia were founded by colonists from the other side of the Aegean. Their settlement was connected with the history of the Ionic people in Attica, which asserts that the colonists were led by Neleus and Androclus, sons of Codrus. So intricate is the coastline that the voyage along its shores was estimated at four times the direct distance. A great part of area was, moreover, occupied by mountains. None of these mountains attains a height of more than 1,200 metres, the geography of Ionia placed it in a strategic position that was both advantageous and disadvantageous. Ionia was always a maritime power founded by a people who made their living by trade in peaceful times, the coast was rocky and the arable land slight. The native Luwians for the most part kept their fields further inland, the coastal cities were placed in defensible positions on islands or headlands situated so as to control inland routes up the rift valleys. The people of those valleys were of different ethnicity, the populations of the cities came from many civilizations in the eastern Mediterranean. Ancient demographics are available only from literary sources, Herodotus states that in Asia the Ionians kept the division into twelve cities that had prevailed in Ionian lands of the north Peloponnese, their former homeland, which became Achaea after they left. These Asian cities were Miletus, Myus, Priene, Ephesus, Colophon, Lebedos, Teos, Erythrae, Clazomenae and Phocaea, together with Samos and Chios. Smyrna, originally an Aeolic colony, was occupied by Ionians from Colophon. These cities do not match those of Achaea, moreover, the Achaea of Herodotus time spoke Doric, but in Homer it is portrayed as being in the kingdom of Mycenae, which most likely spoke Mycenaean Greek, which is not Doric. If the Ionians came from Achaea, they departed during or after the change from East Greek to West Greek there, Mycenaean continued to evolve in the mountainous region of Arcadia. Miletus and some other cities founded earlier by non-Greeks received populations of Mycenaean Greeks probably under the name of Achaeans, the tradition of Ionian colonizers from Achaea suggests that they may have been known by both names even then. In the Indian historic literary texts, the Ionians are referred to as yavanar or yona, in modern Turkish, the people of that region were called yunan and the country that is now Greece is known as Yunanistan

Thrace
–
It comprises southeastern Bulgaria, northeastern Greece, and the European part of Turkey. In antiquity, it was referred to as Europe, prior to the extension of the term to describe the whole continent. The name Thrace comes from the Thracians, an ancient Indo-European people inhabiting Southeastern Europe, the word itself was established by the Greeks for referring to the Thracian tribes, from Ancient Greek Thrake, descending from Thrāix. The name of the continent Europe first referred to Thrace proper, the region obviously took the name of the principal river there, Hebros, probably from the Indo-European arg white river, according to an alternative theory, Hebros means goat in Thracian. In Turkey, it is referred to as Rumeli, Land of the Romans. The name appears to derive from an ancient heroine and sorceress Thrace, who was the daughter of Oceanus and Parthenope, the historical boundaries of Thrace have varied. In one ancient Greek source, the very Earth is divided into Asia, Libya, Europa and this largely coincided with the Thracian Odrysian kingdom, whose borders varied over time. After the Macedonian conquest, this regions former border with Macedonia was shifted from the Struma River to the Mesta River and this usage lasted until the Roman conquest. Henceforth, Thrace referred only to the tract of land covering the same extent of space as the modern geographical region. The medieval Byzantine theme of Thrace contained only what today is Eastern Thrace, the largest cities of Thrace are, İstanbul, Plovdiv, Burgas, Stara Zagora, Haskovo, Yambol, Komotini, Alexandroupoli, Xanthi, Edirne, Çorlu and Tekirdağ. Most of the Bulgarian and Greek population are Christians, while most of the Turkish inhabitants of Thrace are Muslims, Ancient Greek mythology provides them with a mythical ancestor, named Thrax, son of the war-god Ares, who was said to reside in Thrace. The Thracians appear in Homers Iliad as Trojan allies, led by Acamas, later in the Iliad, Rhesus, another Thracian king, makes an appearance. Cisseus, father-in-law to the Trojan elder Antenor, is given as a Thracian king. Homeric Thrace was vaguely defined, and stretched from the River Axios in the west to the Hellespont, Greek mythology is replete with Thracian kings, including Diomedes, Tereus, Lycurgus, Phineus, Tegyrius, Eumolpus, Polymnestor, Poltys, and Oeagrus. In addition to the tribe that Homer calls Thracians, ancient Thrace was home to other tribes, such as the Edones, Bisaltae, Cicones. Thrace is also mentioned in Ovids Metamorphoses in the episode of Philomela, Procne, Tereus, the King of Thrace, lusts after his sister-in-law, Philomela. He kidnaps her, holds her captive, rapes her, Philomela manages to get free, however. She and her sister, Procne, plot to get revenge, by killing Itys, at the end of the myth, all three turn into birds – Procne, a swallow, Philomela, a nightingale, and Tereus, a hoopoe

Chalcidice or Chalkidike or Chalkidiki or Halkidiki, is a peninsula and regional unit of Greece, part of the Region of Central Macedonia in Northern Greece. The autonomous Mount Athos region constitutes the easternmost part of the peninsula, the capital of Chalkidiki is the main town of Polygyros, located in the centre of the peninsula. Chalkidiki today is a summer tourist destination. Aristotle was born here in 384 B. C, the Cholomontas mountains lie in the north-central part of Chalkidiki.

Its largest towns are Nea Moudania, Nea Kallikrateia and the town of Polygyros.

Chalkidiki was an important theatre of war during the Peloponnesian War between Athens and Sparta, later, the Greek colonies of the peninsula were conquered by Philip II of Macedon and Chalkidiki became part of Macedonia. After the end of the wars between the Macedonians and the Romans, the became part of the Roman Empire, along with the rest of Greece. At the end of the Roman Republic a Roman colony was settled in Cassandreia, during the following centuries, Chalkidiki was part of the Byzantine Empire.

Akanthos was an ancient Greek city on the Athos peninsula. It was located near the town of Ierissos on the north-east side of Akti. The name of the ancient city is due to the nature of the area or to the thorny nature of the towns foundation. It was founded by 7th century BC by colonists from Andros, plutarch, on the other hand, referred to it as a mixed colony of Andrians and local Chalcidians, which was founded on the Coast of Drakontos, in place of a preexisting civilization. He writes that settlers from Andros and Chalcis arrived on the shore at the same time, the natives of Acanthus, seeing the crowd of settlers, became frightened and left the city. The settlers sent an explorer each to see what had happened and, as they approached the city and realized it was empty, ran to be the first to take over the land for their fellow countrymen. The Chalcidian was the fastest but the Andrian, seeing he was losing, stopped and threw his spear on the walls gate, a court case followed, which was won by the Andrians, because as they protested, they had just about taken over the city first. Its economic resources emanated from the mining and wood from the nearby forests and they declared one of his relatives who died in the area, named Artahei, a hero, and willingly took part in the expedition against Greece. After the Persian wars Acanthus became a member of the Athenian Alliance, in the initial phase of the establishment of the Chalcidice League, it was mainly smaller towns and cities in Macedonia that were enrolled. Only when it was established was an offer made to Acanthus. When this was refuse an offer was made but with the threat that force would be used should Acanthus refuse to join the federation. The townsfolk refused to join it, in due to the old quarrel with the Chalcidians. Under threat from the Chalcidians, Acanthus called in Spartas help, which came in 382 BC when the Spartans and Acanthians captured and destroyed Olynthos and the alliance, at least temporarily. Acanthuss staying-out of the alliance meant that in 350 BC, when it was conquered by Philip II of Macedon, later it was incorporated to the region of Ouranoupolis, a new city that was founded by Alexarchos, in the isthmus, between the Strymoinan and the Singitic gulfs. According to Livy, Acanthus was attacked by a Roman-Pergamene fleet in 199 BC during the Second Macedonian War, the Romans later exploited all the natural sources of wealth and its harbor, and the town continued through the Roman and Byzantine period. The ancient city extended along a hillside, about 0.6 km south-east of modern Ierissos. Remains of walls, a citadel, and Hellenistic buildings survive, along with a deserted Byzantine church. The city itself has not been excavated, but the necropolis has, starting in 1973, particularly extensive is the sight of the cemetery along the seaside of Ierissos
