Tyrrhenian Sea
–
The Tyrrhenian Sea is part of the Mediterranean Sea off the western coast of Italy. It is named for the Tyrrhenian people, identified since the 6th century BCE with the Etruscans of Italy, the sea is bounded by the islands of Corsica and Sardinia, the Italian peninsula to the east, and the island of Sicily. The maximum depth of the sea is 3,785 metres, the Tyrrhenian Sea is situated near where the African and Eurasian Plates meet, therefore mountain chains and active volcanoes such as Mount Marsili are found in its depths. The eight Aeolian Islands and Ustica are located in the part of the sea. On the Southwest, A line running from Cape Lilibeo to the South extreme of Cape Teulada in Sardinia, in the Strait of Bonifacio, A line joining the West extreme of Cape Testa in Sardinia with the Southwest extreme of Cape Feno in Corsica. On the North, A line joining Cape Corse in Corsica, with Tinetto Island and thence through Tino, there are four exits from the Tyrrhenian Sea, The Tyrrhenian Basin is divided into two basins, the Vavilov plain and the Marsili plain. They are separated by the ridge known as the Issel Bridge. Its name derives from the Greek name for the Etruscans, who were said to be emigrants from Lydia, the Etruscans settled along the coast of modern Tuscany and referred to the water as the Sea of the Etruscans. The main ports of the Tyrrhenian Sea in Italy are, Naples, Palermo, Civitavecchia, Salerno, Trapani, in France the most important port is Bastia. Note that even though the port of Rome is frequently used. Instead, the port of Rome refers to the facilities at Civitavecchia, some 68 km to the northwest of Rome. Giglio Porto is an island port in this area. It rose to prominence, when the Costa Concordia ran aground a few metres off the coast of Giglio, the ship was recently removed and towed to Genoa. In Greek mythology, it is believed that the cliffs above the Tyrrhenian Sea housed the four winds kept by Aeolus, the winds are the Mistral from the Rhône valley, the Libeccio from the southwest, and the Sirocco and Ostro from the south

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

Regions of Italy
–
The regions of Italy are the first-level administrative divisions of Italy, constituting its second NUTS administrative level. There are 20 regions, of five are constitutionally given a broader amount of autonomy granted by special statutes. Each region, except for the Aosta Valley, is divided into provinces, regions are autonomous entities with powers defined in the Constitution. As the administrative districts of the state during the Kingdom of Italy. The original draft list comprised the Salento region, friuli and Venezia Giulia were separate regions, and Basilicata was named Lucania. Abruzzo and Molise were identified as regions in the first draft. They were later merged into Abruzzo e Molise in the constitution of 1948. Implementation of regional autonomy was postponed until the first Regional Elections of 1970, the ruling Christian Democracy party did not want the opposition Italian Communist Party to gain power in the regions, where it was historically rooted. Regions acquired a significant level of autonomy following a reform in 2001. In June 2006 the proposals, which had been associated with Lega Nord. The results varied considerably among the regions, ranging from 55. 3% in favour in Veneto to 82% against in Calabria, number of regions controlled by each coalition since 1995, Macroregions are the first-level NUTS of the European Union. These regions, whose statutes are approved by their councils, were created in 1970. Since the constitutional reform of 2001 they have had residual legislative powers, the regions have exclusive legislative power with respect to any matters not expressly reserved to state law. Yet their financial autonomy is quite modest, they just keep 20% of all levied taxes, Article 116 of the Italian Constitution grants to five regions home rule, acknowledging their powers in relation to legislation, administration and finance. These regions became autonomous in order to take into account cultural differences, moreover, the government wanted to prevent their secession from Italy after the Second World War. Trentino-Alto Adige/Südtirol constitutes a special case, the region is nearly powerless, and the powers granted by the regions statute are mostly exercised by the two autonomous provinces within the region, Trentino and South Tyrol. In this case, the regional institution plays a coordinating role, the latter is directly elected by the citizens of each region, with the exceptions of Aosta Valley and Trentino-Alto Adige/Südtirol, where he is chosen by the regional council. Under the 1995 electoral law, the winning coalition receives a majority of seats on the council

Sicily
–
Sicily is the largest island in the Mediterranean Sea. It is an autonomous Region of Italy, along with surrounding minor islands, Sicily is located in the central Mediterranean Sea, south of the Italian Peninsula, from which it is separated by the narrow Strait of Messina. Its most prominent landmark is Mount Etna, the tallest active volcano in Europe, the island has a typical Mediterranean climate. The earliest archaeological evidence of activity on the island dates from as early as 12,000 BC. It became part of Italy in 1860 following the Expedition of the Thousand, a revolt led by Giuseppe Garibaldi during the Italian unification, Sicily was given special status as an autonomous region after the Italian constitutional referendum of 1946. Sicily has a rich and unique culture, especially regard to the arts, music, literature, cuisine. It is also home to important archaeological and ancient sites, such as the Necropolis of Pantalica, the Valley of the Temples, Sicily has a roughly triangular shape, earning it the name Trinacria. To the east, it is separated from the Italian mainland by the Strait of Messina, about 3 km wide in the north, and about 16 km wide in the southern part. The northern and southern coasts are each about 280 km long measured as a line, while the eastern coast measures around 180 km. The total area of the island is 25,711 km2, the terrain of inland Sicily is mostly hilly and is intensively cultivated wherever possible. Along the northern coast, the ranges of Madonie,2,000 m, Nebrodi,1,800 m. The cone of Mount Etna dominates the eastern coast, in the southeast lie the lower Hyblaean Mountains,1,000 m. The mines of the Enna and Caltanissetta districts were part of a leading sulphur-producing area throughout the 19th century, Sicily and its surrounding small islands have some highly active volcanoes. Mount Etna is the largest active volcano in Europe and still casts black ash over the island with its ever-present eruptions and it currently stands 3,329 metres high, though this varies with summit eruptions, the mountain is 21 m lower now than it was in 1981. It is the highest mountain in Italy south of the Alps, Etna covers an area of 1,190 km2 with a basal circumference of 140 km. This makes it by far the largest of the three volcanoes in Italy, being about two and a half times the height of the next largest, Mount Vesuvius. In Greek Mythology, the deadly monster Typhon was trapped under the mountain by Zeus, Mount Etna is widely regarded as a cultural symbol and icon of Sicily. The Aeolian Islands in the Tyrrhenian Sea, to the northeast of mainland Sicily form a volcanic complex, the three volcanoes of Vulcano, Vulcanello and Lipari are also currently active, although the latter is usually dormant

Provinces of Italy
–
In Italy, a province is an administrative division of intermediate level between a municipality and a region. There are currently 107 provinces in Italy, a further 4 such cities were added later. The reorganization of the Italian provinces became operative by January 2015, a province of the Italian Republic is composed of many municipalities. Usually several provinces together form a region, the region of Aosta Valley is the sole exception – it is not subdivided into provinces, the three main functions devolved to provinces are, local planning and zoning, provision of local police and fire services, transportation regulation. The number of provinces in Italy has been growing in recent years. Usually, the name is the same as that of its capital city. According to the 2014 reform, each province is headed by a President assisted by a body, the Provincial Council, and an executive body. President and members of Council are elected together by mayors and city councilors of each municipality of the province, the Executive is chaired by the President who appoint others members, called assessori. Since 2015 the President and others members of the Council will not receive a salary, in each province there is also a Prefect, a representative of the central government who heads an agency called prefettura-ufficio territoriale del governo. The Questor is the head of States Police in the province, there is also a provinces police force depending from local government, called provincial police. Sardinia - following the outcome of the referendums of 2012 it was decreed that such institutions should be reformed or abolished by March 2013. In January 2014 the Sardinian Regional Administrative Court declared unconstitutional the abolition of the Sardinian provinces, sicily - provinces were replaced by Free Communal Consortia in 2013. In 1861, at the birth of the Kingdom of Italy, however, at that time the national territory was smaller than the current one, regions of Veneto, Friuli-Venezia Giulia, Trentino Alto Adige and Lazio were not included in the kingdom. In 1866, following the Third Independence War, territories of Veneto, Friuli, there were therefore nine more provinces, Belluno, Mantua, Padua, Rovigo, Treviso, Venice, Verona, Vicenza and Udine, all previously part of the Austrian Empire. Eventually, in 1870, following the annexion of Rome and its province from the Papal States, after the First World War, new territories were annexed to Italy. The Province of Trento was created in 1920, Provinces of La Spezia, Trieste and Ionio in 1923. In 1924 the new provinces of Fiume, Pola, and Zara were created, in 1927, following a Royal charter, a general province rearrangement took place. 17 new provinces were created and the province of Caserta was suppressed, in the same year the institution of circondari, sub-provincial wards created before the unification, was abolished

Province of Messina
–
Messina was a province in the autonomous island region of Sicily in Italy. Its capital was the city of Messina and it was replaced by the Metropolitan City of Messina. It had an area of 3,247 square kilometres, which amounts to 12.6 percent of area of the island. There are 108 comuni in the province, see Comuni of the Province of Messina, the province included the Aeolian Islands, all part of the comune of Lipari. The territory is mountainous, with the exception of alluvial plain at the mouths of the various rivers. Much of the population is concentrated in the area, after the hill towns have been largely abandoned from the 19th century. The main mountain ridges are the Peloritani, up to 1,300 metres in elevation, and the Nebrodi, up to 1,900 metres, rivers of the province include the Alcantara and the Pollina, which forms the border with the province of Palermo to the west

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

Italian language
–
By most measures, Italian, together with Sardinian, is the closest to Latin of the Romance languages. Italian is a language in Italy, Switzerland, San Marino, Vatican City. Italian is spoken by minorities in places such as France, Montenegro, Bosnia & Herzegovina, Crimea and Tunisia and by large expatriate communities in the Americas. Many speakers are native bilinguals of both standardized Italian and other regional languages, Italian is the fourth most studied language in the world. Italian is a major European language, being one of the languages of the Organisation for Security and Cooperation in Europe. It is the third most widely spoken first language in the European Union with 65 million native speakers, including Italian speakers in non-EU European countries and on other continents, the total number of speakers is around 85 million. Italian is the working language of the Holy See, serving as the lingua franca in the Roman Catholic hierarchy as well as the official language of the Sovereign Military Order of Malta. Italian is known as the language of music because of its use in musical terminology and its influence is also widespread in the arts and in the luxury goods market. Italian has been reported as the fourth or fifth most frequently taught foreign language in the world, Italian was adopted by the state after the Unification of Italy, having previously been a literary language based on Tuscan as spoken mostly by the upper class of Florentine society. Its development was influenced by other Italian languages and to some minor extent. Its vowels are the second-closest to Latin after Sardinian, unlike most other Romance languages, Italian retains Latins contrast between short and long consonants. As in most Romance languages, stress is distinctive, however, Italian as a language used in Italy and some surrounding regions has a longer history. What would come to be thought of as Italian was first formalized in the early 14th century through the works of Tuscan writer Dante Alighieri, written in his native Florentine. Dante is still credited with standardizing the Italian language, and thus the dialect of Florence became the basis for what would become the language of Italy. Italian was also one of the recognised languages in the Austro-Hungarian Empire. Italy has always had a dialect for each city, because the cities. Those dialects now have considerable variety, as Tuscan-derived Italian came to be used throughout Italy, features of local speech were naturally adopted, producing various versions of Regional Italian. Even in the case of Northern Italian languages, however, scholars are not to overstate the effects of outsiders on the natural indigenous developments of the languages

Sicilian language
–
Sicilian is a Romance language spoken on the island of Sicily and its satellite islands. It is also spoken in southern and central Calabria, in the parts of Apulia, Salento, and Campania, on the Italian peninsula. The Ethnologue describes Sicilian as being distinct enough from Standard Italian to be considered a language and is recognized as a minority language by UNESCO. Some assert that Sicilian represents the oldest Romance language derived from Vulgar Latin, Sicilian has the oldest literary tradition of the Italic languages. Sicilian is currently spoken by the majority of the inhabitants of Sicily, the latter are found in the countries which attracted large numbers of Sicilian immigrants during the course of the past century or so, especially the United States, Canada, Australia and Argentina. In the past two or three decades, large numbers of Sicilians were also attracted to the zones of northern Italy and indeed the rest of the European Union. It is not used as an official language anywhere, even within Sicily, there is currently no central body, in Sicily or elsewhere, that regulates the language in any way. However, since its inception in 1951, the Centro di studi filologici e linguistici siciliani in Palermo has been researching and publishing information on the Sicilian language. The autonomous regional parliament of Sicily has legislated to encourage the teaching of Sicilian at all schools, further, the Sicilian language would be protected and promoted under the European Charter for Regional or Minority Languages. However, Italy has signed this treaty, but the Italian Parliament has not ratified it, the term Calabro-Sicilian refers to the fact that a form of Sicilian, or a dialect closely related to Sicilian, is spoken in central and southern Calabria. Sicilianu is the name of the language in Sicily itself, the term Siculu describes one of the larger prehistoric groups living in Sicily before the arrival of Greeks in the 8th century BC. It can also be used as an adjective to qualify, or further elaborate on, the very earliest influences, visible in Sicilian to this day, exhibit both prehistoric Mediterranean elements and prehistoric Indo-European elements, and occasionally a blending of both. Ruffino 2001 Before the Roman conquest, Sicily was occupied by populations considered indigenous, including Sicels, Sicani, Elymians, the Greek language influence remains strongly visible, while the influences from the other groups are less obvious. What can be stated with certainty is that there remain pre-Indo-European words in Sicilian of an ancient Mediterranean origin, of the three main prehistoric groups, only the Sicels were Indo-European, and their speech is likely to have been closely related to that of the Romans. The following table, listing words for twins, illustrates the difficulty linguists face in tackling the various sub-strata of the Sicilian language, a similar qualifier can be applied to many of the words that appear in this article. For instance, by the time the Romans had occupied Sicily during the 3rd century BC, the words with a prehistoric Mediterranean derivation often refer to plants native to the Mediterranean region or to other natural features. g. of a fruit timpa crag, cliff. The Sicels are a source of such words, but there is also the possibility of a cross-over between ancient Mediterranean words and introduced Indo-European forms. Some examples of Sicilian words with an ancient Indo-European origin, dudda mulberry, the latter would bring with them the Vulgar Latin from that region, a language not too different from that to be found in central Italy at the time

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

Volcano
–
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earths volcanoes occur because its crust is broken into 17 major, therefore, on Earth, volcanoes are generally found where tectonic plates are diverging or converging. This type of volcanism falls under the umbrella of plate hypothesis volcanism, Volcanism away from plate boundaries has also been explained as mantle plumes. These so-called hotspots, for example Hawaii, are postulated to arise from upwelling diapirs with magma from the boundary,3,000 km deep in the Earth. Volcanoes are usually not created where two plates slide past one another. Erupting volcanoes can pose hazards, not only in the immediate vicinity of the eruption. Historically, so-called volcanic winters have caused catastrophic famines, the word volcano is derived from the name of Vulcano, a volcanic island in the Aeolian Islands of Italy whose name in turn comes from Vulcan, the god of fire in Roman mythology. The study of volcanoes is called volcanology, sometimes spelled vulcanology, at the mid-oceanic ridges, two tectonic plates diverge from one another as new oceanic crust is formed by the cooling and solidifying of hot molten rock. Most divergent plate boundaries are at the bottom of the oceans, therefore, most volcanic activity is submarine, black smokers are evidence of this kind of volcanic activity. Where the mid-oceanic ridge is above sea-level, volcanic islands are formed, for example, subduction zones are places where two plates, usually an oceanic plate and a continental plate, collide. In this case, the plate subducts, or submerges under the continental plate forming a deep ocean trench just offshore. In a process called flux melting, water released from the subducting plate lowers the temperature of the overlying mantle wedge. This magma tends to be very viscous due to its high content, so it often does not reach the surface. When it does reach the surface, a volcano is formed, typical examples of this kind of volcano are Mount Etna and the volcanoes in the Pacific Ring of Fire. Because tectonic plates move across them, each volcano becomes dormant and is eventually re-formed as the plate advances over the postulated plume and this theory is currently under criticism, however. The most common perception of a volcano is of a mountain, spewing lava and poisonous gases from a crater at its summit, however. The features of volcanoes are more complicated and their structure. Some volcanoes have rugged peaks formed by lava domes rather than a summit crater while others have features such as massive plateaus
12.
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.

Lipari
–
Lipari is the largest of the Aeolian Islands in the Tyrrhenian Sea off the northern coast of Sicily, southern Italy, it is also the name of the islands main town. Its population is 11,231, but during the May to September tourist season, Lipari is the largest of a chain of islands in a volcanic archipelago situated in between Vesuvius and Etna. The island has an area of 37.6 square kilometres and is 30 kilometres from Sicily. Geologists agree on the fact that Lipari was created by a succession of four volcanic movements, a further important phenomenon should have happened around 9000 BC. The last recorded eruptions occurred in the fifth century CE when airborne pumice, together with volcanic ash, the volcanoes are considered active, and steaming fumaroles and hydrothermal activity may still be seen. As a result of its origin, the island is covered with pumice. Pumice mining has become an industry on Lipari, and the pale pumice from Lipari is shipped worldwide. Liparis history is rich in incidents as witnessed by the recent retrievals of several necropolis, humans seem to have inhabited the island already in 5000 BC, though a local legend gives the eponymous name Liparus to the leader of a people coming from Campania. In the Mycenaean Period, Lipari has yielded pottery from LHI to LHIII, liparis continuous occupation may have been interrupted violently when in the late 9th century an Ausonian civilization site was burned and apparently not rebuilt. Many household objects have been retrieved from the charred site, Greek colonists from Knidos arrived at Lipara ~580 BC after their first colonization attempt in Sicily failed and their leader, Pentathlos, was killed. They settled on the site of the now known as Castello. The colony successfully fought the Etruscans for control of the Tyrrhenian Sea, Lipara prospered, but in 304 Agathokles took the town by treachery and is said to have lost all of his pillage from it in a storm at sea. Many objects recovered from old wrecks are now in the Aeolian Museum of Lipari, Lipara became a Carthaginian naval base during the first Punic War, but fell to Roman forces in 252–251 BC, and was occupied by Agrippa in Octavians campaign against Pompei. Under the Roman Empire, it was a place of retreat, the presence of the relics has been attested since at least 546. In the 9th century, Sicily was conquered by the Arabs, in 839 the Saracens slaughtered much of the population, the relics of St. Bartholomew were moved to Benevento, and Lipari was eventually almost totally abandoned. The Normans conquered the Arabs throughout Sicily between 1060 and 1090, and repopulated the island once their rule was secure, the Lipari episcopal seat was reinstated in 1131. Though still plagued by raids, the island was continually populated from this time onward. In 1544, Hayreddin Barbarossa, together with the French fleet of Captain Polin under a Franco-Ottoman alliance, ransacked Lipari and he also mentioned the tears, wailings and cries of these poor Lipariotes, the father regarding his son and the mother her daughter

Vulcano
–
Vulcano is a small volcanic island in the Tyrrhenian Sea, about 25 km north of Sicily and the southernmost of the eight Aeolian Islands. It is 21 km2 in area, rises to 499 m above sea level, the Romans used the island mainly for raw materials, harvesting wood and mining alum and sulfur. This was the activity on the island until the end of the 19th Century. Stevenson lived on Vulcano until the last major eruption on the island, the eruption lasted the better part of two years, by which time Stevenson had sold all of his property to the local populace, and never returned to the island. The volcanic activity in the region is largely the result of the northward-moving African Plate meeting the Eurasian Plate, at the north of the island is Vulcanello, connected to the rest of it by an isthmus which is flooded in bad weather. It emerged from the sea during an eruption in 183 BC as a separate islet, occasional eruptions from its three cones with both pyroclastic flow deposits and lavas occurred from then until 1550, the last eruption creating a narrow isthmus connecting it to Vulcano. Vulcano has been quiet since the eruption of the Fossa cone on 3 August 1888 to 1890 and this eruption of Vulcano was carefully documented at the time by Giuseppe Mercalli. Mercalli described the eruptions as. Explosions sounding like a cannon at irregular intervals, as a result, vulcanian eruptions are based on this description. A typical vulcanian eruption can hurl blocks of solid material several hundreds of metres from the vent, Mercalli reported blocks from the 1888-1890 eruption fell in the sea between Vulcano and Lipari, several were photographed by him or his assistants that had fallen on the island of Vulcano. The Ancient Greeks named the island Therassía and Thérmessa, the island appeared in their myths as the private workshop of the Olympian god Hephaestus, protector of the blacksmiths, he owned another two at Etna and Olympus. Strabo also mentions Thermessa as sacred place of Hephaestus, but it is not clear if it was a name for the island. Similarly the Romans believed that Vulcano was the chimney of the god Vulcans workshop, the island had grown due to his periodic clearing of cinders and ashes from his forge. The earthquakes that either preceded or accompanied the explosions of ash were considered to be due to Vulcan making weapons for Mars, since Vulcano island has volcanic activity, this island is a place where thermophiles and hyperthermophiles are likely to be found. In fact, the hyperthermophilic archaea Pyrococcus furiosus was described for the first time when it was isolated from sediments of this island by Gerhard Fiala and Karl Stetter.

Salina, Sicily
–
Salina is one of the Aeolian Islands north of Sicily, southern Italy. It is the second largest island in the archipelago, Salina is divided between three comuni, Santa Marina on the eastern coast, Malfa to the north, and Leni to the south-west. From Leni down towards the sea is the village of Rinella, above the village of Leni is Valdichiesa in the center of the island. The other smaller villages are Capo Faro, Pollara and Lingua, there are currently approximately 4,000 residents living on the island. Salina has a surface area of 27 km2. It is included on the World Heritage List especially because of its worth for vulcanology, a lower crater lies just above sea level near the small village of Pollara, on the north west corner of the island, half of which has fallen into the sea. All that remains of the activities are some post-volcanic phenomena called “gurgling”. The gurgling phenomena are at Rinella and are caused by the emission of underwater gas. When this phenomenon is at its most active it can lift the sea-bed, from a distance Salina looks entirely green with two rounded high mountains and a smooth coastline. More than 400 different types of plants grow on the island and grapes, olives, Salina was the first among the Aeolian islands to protect its environment with a natural preserve, known as the Riserva Naturale del Fossa delle Felci e dei Porri. The island is notable for Malvasia, a famous white wine that is only produced on Salina. It is golden in colour and has an intense, delicately sweet bouquet, there has also been a local revival of the production of superior-quality low-acid olive oil. It is claimed that Salina produces the best capers in the world, a Greek settlement, from the fourth century BC through to the times of Imperial Rome, once lay on the modern-day site of the small town of Santa Marina. A number of tombs from this era have been discovered further inland, several traces of Greek and Roman culture have been found on the island. In the Hellenic Age the island was named Didyme, a Greek name which refers to the two mountains as twins, the island was inhabited as far back as the Bronze Age and has been developed and then abandoned many times over the subsequent millennia. Areas on the island, including the two peaks, were designated as a natural reserve in 1981. The salt lake in Lingua was once a site for production of sea salt, on the slopes of the Fossa, several Roman tombs have been excavated. Sanctuary of the Madonna del Terzito, located between Malfa and Leni in the known as Valdichiesa between the twin volcanoes, and built in 1630

Stromboli
–
Stromboli is a small island in the Tyrrhenian Sea, off the north coast of Sicily, containing one of the three active volcanoes in Italy. It is one of the eight Aeolian Islands, a volcanic arc north of Sicily and this name is derived from the Ancient Greek name Strongulē which was given to it because of its round swelling form. The islands population is about 500, the most recent major eruption was on 13 April 2009. Stromboli stands 926 m above sea level, and over 2,700 m on average above the sea floor, there are three active craters at the peak. Two kilometers to the northeast lies Strombolicchio, the volcanic plug remnant of the original volcano, mt. Stromboli has been in almost continuous eruption for the past 2,000 years. A pattern of eruption is maintained in which occur at the summit craters, with mild to moderate eruptions of incandescent volcanic bombs. This Strombolian eruption, as it is known, is observed at other volcanoes worldwide. Volcanic gas emissions from this volcano are measured by a Multi-Component Gas Analyzer System, the two villages San Bartolo and San Vincenzo lie in the northeast while the smaller village Ginostra lies in the southwest. Administratively, they are one of the frazione of Lipari, in the early 1900s a few thousand people inhabited the island, but after several emigrations the population numbered a few hundred by the mid-1950s. In Journey to the Center of the Earth by Jules Verne, tolkien identified his fictional volcano Mount Doom in Mordor with the volcano of Stromboli, according to scholar Clyde S. Kilby. Stromboli, also known as, Stromboli, land of God, is an Italian-American film set on Stromboli, directed by Roberto Rossellini and starring Ingrid Bergman. The climax of the 2007 novel The Book of the Dead, by Douglas Preston and Lincoln Child, in 2013 Geir Jenssen released an album entitled Stromboli, consisting of field recordings made at edge of Strombolis crater on 19 July 2012.

Filicudi
–
Filicudi is one of eight islands that make up the Aeolian archipelago, situated 30–50 km northeast of the island of Sicily, southern Italy. It is a frazione of the comune of Lipari and its total area is 9.5 km2. There are several villages on the island, which include Pecorini Mare. Filicudis lands are capable of producing wine, olive oil, grain, in 1997, three quarters, approximately 7 km2 of Filicudi was turned into a Natural Reserve. The highest point is Monte Fossa Felci at 774 m, other points include Monte Montagnola at 349 m and Monte Terrione at 278 m. At Capo Graziano are the remains of a Bronze Age village dating back to the second millennium BCE, off the coast, the volcanic finger-like rock of La Canna rises about 74 metres above the sea. The modern name of Filicudi is a corruption of the ancient Greek name for the island, the island, like the other Aeolian Islands, was settled since the Neolithic Age, around 3000 BCE. As evidenced by archaeological findings, the island was occupied by a new people during the Bronze Age, the island was uninhabited for many centuries until occupied by the Greeks. Roman and Byzantine remains can also be found on the island, since the 1970s Filicudi was rediscovered and populated by photographers and artists such as Sergio Libiszewsky, Ettore Sottsas, novelist Roland Zoss, and editor Giulio Einaudi. Their perceptions brought the island into the focus of modern tourism, john Bonica, anesthesiologist and professional wrestler Roland Zoss, novelist and composer List of volcanoes in Italy

Alicudi
–
Alicudi is the westernmost of the eight islands that make up the Aeolian archipelago, a volcanic island chain north of Sicily. The island is about 40 km west of Lipari, has an area of 5.2 km2. It is located at 38°32′45″N 14°21′00″E, the island was formed by the long-extinct Montagnola volcano, roughly 150,000 years ago. It has been suggested that the last evolutive act of the island took place only 27,000 years ago, the island was first populated as long ago as 17th century BC, as some archaeological evidence from this period has been found. Roman ceramic fragments, dating from many centuries later, can be found on the eastern coast of the island, for many centuries, Alicudi was the target of frequent incursions by pirates. Today there are around 120 inhabitants who live off fishing. There is only one restaurant on the island and the menu depends greatly on what fish the fishermen have caught.

Panarea
–
Panarea is the second smallest of the eight Aeolian Islands, a volcanic island chain north of Sicily, southern Italy. It is a frazione of the comune of Lipari, there are currently about 280 residents living on the island year-round, however the population increases dramatically in summer with the influx of tourists. In recent years, the island has become known internationally for its celebrity visitors, the island is an inactive volcano with a total surface area of only 3.4 km2. The highest point on the island, Punta del Corvo, is 421 m above sea level, there are thermal springs near the village of Punta di Peppe e Maria. Scuba diving is an excursion on this tiny island. In antiquity, the island was named Euonymos, the islet of Basiluzzo. There is archaeological evidence on the island dating back to Mycenaean inhabitants, there were people still living on the island until pirates and other Mediterranean raiders made life unbearable after the fall of the Western Roman Empire. In modern times, Panarea has become a vacation spot. In 2011, it was described by W magazine as the epicenter of the chicest summer scene in the Mediterranean, Panarea and the entire Aeolian chain were declared a UNESCO World Heritage site in 2000. Largely because of this, construction and development are strictly regulated, most residences admit only temporary occupancy, and the few year-round homes available are highly expensive and difficult to obtain.

Fumarole
–
A fumarole is an opening in a planets crust, often in areas surrounding volcanoes, which emits steam and gases such as carbon dioxide, sulfur dioxide, hydrogen chloride, and hydrogen sulfide. The steam forms when superheated water vaporizes as its pressure drops when it emerges from the ground, the name solfatara, from the Italian solfo, sulfur, is given to fumaroles that emit sulfurous gases. Fumaroles may occur along tiny cracks or long fissures, in clusters or fields. A fumarole field is an area of springs and gas vents where magma or hot igneous rocks at shallow depth release gases or interact with groundwater. From the perspective of groundwater, a fumarole could be described as a hot spring that boils off all its water before the water reaches the surface. Fumaroles may persist for decades or centuries if located above a persistent heat source, the Valley of Ten Thousand Smokes, for example, was formed during the 1912 eruption of Novarupta in Alaska. Initially, thousands of fumaroles occurred in the ash from the eruption. An estimated four thousand fumaroles exist within the boundaries of Yellowstone National Park in the United States, in April 2006 fumarole emissions killed three ski-patrol workers east of Chair 3 at Mammoth Mountain Ski Area in California. The workers were overpowered by toxic fumes that had accumulated in a crevasse they had fallen into, another example is an array of fumaroles in the Valley of Desolation in Morne Trois Pitons National Park in Dominica.

Volcanic arc
–
A volcanic arc is a chain of volcanoes formed above a subducting plate, positioned in an arc shape as seen from above. Offshore volcanoes form islands, resulting in an island arc. Generally, volcanic arcs result from the subduction of a tectonic plate under another tectonic plate. The oceanic plate is saturated with water, and volatiles such as water drastically lower the point of the mantle. As the oceanic plate is subducted, it is subjected to greater and greater pressures with increasing depth and this pressure squeezes water out of the plate and introduces it to the mantle. Here the mantle melts and forms magma at depth under the overriding plate, the magma ascends to form an arc of volcanoes parallel to the subduction zone. The Hawaiian Islands form a typical hotspot chain, the islands to the northwest are smaller and more lush than the recently created Hawaii island itself. Hotspot volcanoes are known as intra-plate volcanoes, and the islands they create are known as Volcanic Ocean Islands. Volcanic arcs do not generally such a simple age-pattern. There are two types of volcanic arcs, oceanic arcs form when oceanic crust subducts beneath other oceanic crust on an adjacent plate, continental arcs form when oceanic crust subducts beneath continental crust on an adjacent plate, creating an arc-shaped mountain belt. In some situations, a subduction zone may show both aspects along its length, as part of a plate subducts beneath a continent and part beneath adjacent oceanic crust. Volcanoes are present in almost any mountain belt, but this does not make it a volcanic arc, often there are isolated, but impressively huge volcanoes in a mountain belt. For instance, Vesuvius and the Etna volcanoes in Italy are part of separate, the active front of a volcanic arc is the belt where volcanism develops at a given time. Active fronts may move over time, changing their distance from the trench as well as their width. This loss of water is due to the destabilization of the mineral chlorite at approximately 40–60 km depth. On the subducting side of the arc is a deep and narrow oceanic trench. This trench is created by the pull of the relatively dense subducting plate pulling the leading edge of the plate downward. Multiple earthquakes occur along this boundary with the seismic hypocenters located at increasing depth under the island arc

Crust (geology)
–
In geology, the crust is the outermost solid shell of a rocky planet or natural satellite, which is chemically distinct from the underlying mantle. The crust of the Earth is composed of a variety of igneous, metamorphic. The crust is underlain by the mantle, the upper part of the mantle is composed mostly of peridotite, a rock denser than rocks common in the overlying crust. The boundary between the crust and mantle is conventionally placed at the Mohorovičić discontinuity, a boundary defined by a contrast in seismic velocity, the crust occupies less than 1% of Earths volume. The crust of the Earth is of two types, oceanic and continental. The oceanic crust is 5 km to 10 km thick and is composed primarily of basalt, diabase, the continental crust is typically from 30 km to 50 km thick and is mostly composed of slightly less dense rocks than those of the oceanic crust. Some of these less dense rocks, such as granite, are common in the continental crust, both the continental and oceanic crust float on the mantle. Because the continental crust is thicker, it both to greater elevations and greater depth than the oceanic crust. The slightly lower density of continental rock compared to basaltic oceanic rock contributes to the higher relative elevation of the top of the continental crust. As the top of the continental crust reaches elevations higher than that of the oceanic, the temperature of the crust increases with depth, reaching values typically in the range from about 200 °C to 400 °C at the boundary with the underlying mantle. The crust and underlying relatively rigid uppermost mantle make up the lithosphere, because of convection in the underlying plastic upper mantle and asthenosphere, the lithosphere is broken into tectonic plates that move. The temperature increases by as much as 30 °C for every kilometer locally in the part of the crust. Earth has probably always had some form of basaltic crust, in contrast, the bulk of the continental crust is much older. The oldest continental crustal rocks on Earth have ages in the range from about 3.7 to 4, some zircon with age as great as 4.3 billion years has been found in the Narryer Gneiss Terrane. The average age of the current Earths continental crust has been estimated to be about 2.0 billion years, most crustal rocks formed before 2.5 billion years ago are located in cratons. Such old continental crust and the underlying mantle asthenosphere are less dense than elsewhere in Earth, formation of new continental crust is linked to periods of intense orogeny, these periods coincide with the formation of the supercontinents such as Rodinia, Pangaea and Gondwana. The continental crust has a composition similar to that of andesite. The most abundant minerals in Earths continental crust are feldspars, which make up about 41% of the crust by weight, followed by quartz at 12%, Continental crust is enriched in incompatible elements compared to the basaltic ocean crust and much enriched compared to the underlying mantle

Plate tectonics
–
The theoretical model builds on the concept of continental drift developed during the first few decades of the 20th century. The geoscientific community accepted plate-tectonic theory after seafloor spreading was validated in the late 1950s, the lithosphere, which is the rigid outermost shell of a planet, is broken up into tectonic plates. The Earths lithosphere is composed of seven or eight major plates, where the plates meet, their relative motion determines the type of boundary, convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along plate boundaries. The relative movement of the plates typically ranges from zero to 100 mm annually, tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Along convergent boundaries, subduction carries plates into the mantle, the material lost is balanced by the formation of new crust along divergent margins by seafloor spreading. In this way, the surface of the lithosphere remains the same. This prediction of plate tectonics is also referred to as the conveyor belt principle, earlier theories, since disproven, proposed gradual shrinking or gradual expansion of the globe. Tectonic plates are able to move because the Earths lithosphere has greater strength than the underlying asthenosphere. Lateral density variations in the result in convection. Plate movement is thought to be driven by a combination of the motion of the seafloor away from the ridge and drag, with downward suction. Another explanation lies in the different forces generated by forces of the Sun. The relative importance of each of these factors and their relationship to other is unclear. The outer layers of the Earth are divided into the lithosphere and asthenosphere and this is based on differences in mechanical properties and in the method for the transfer of heat. Mechanically, the lithosphere is cooler and more rigid, while the asthenosphere is hotter, in terms of heat transfer, the lithosphere loses heat by conduction, whereas the asthenosphere also transfers heat by convection and has a nearly adiabatic temperature gradient. The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates, Plate motions range up to a typical 10–40 mm/year, to about 160 mm/year. The driving mechanism behind this movement is described below, tectonic lithosphere plates consist of lithospheric mantle overlain by either or both of two types of crustal material, oceanic crust and continental crust. Average oceanic lithosphere is typically 100 km thick, its thickness is a function of its age, as passes, it conductively cools

African Plate
–
The African Plate is a major tectonic plate straddling the equator as well as the prime meridian. It includes much of the continent of Africa, as well as oceanic crust which lies between the continent and various surrounding ocean ridges, between 60 million years ago and 10 million years ago, the Somali Plate began rifting from the African Plate along the East African Rift. All of these are divergent or spreading boundaries with the exception of the northern boundary, the cratons are, from south to north, the Kalahari craton, Congo craton, Tanzania craton and West African craton. The cratons were widely separated in the past, but came together during the Pan-African orogeny, the cratons are connected by orogenic belts, regions of highly deformed rock where the tectonic plates have engaged. The African Plate is rifting in the interior of the African continent along the East African Rift. This rift zone separates the African Plate to the west from the Somali Plate to the east, the African Plates speed is estimated at around 2.15 cm per year. It has been moving over the past 100 million years or so in a general northeast direction and this is drawing it closer to the Eurasian Plate, causing subduction where oceanic crust is converging with continental crust. Along its northeast margin, the African Plate is bounded by the Red Sea Rift where the Arabian Plate is moving away from the African Plate. The New England hotspot in the Atlantic Ocean has probably created a line of mid- to late-Tertiary age seamounts on the African Plate. USGS - Understanding plate motions Meijer, P. Th, wortel, M. J.

Continental shelf
–
The continental shelf is an underwater landmass which extends from a continent, resulting in an area of relatively shallow water known as a shelf sea. Much of the shelves were exposed during glacial periods and interglacial periods, the shelf surrounding an island is known as an insular shelf. The continental margin, between the shelf and the abyssal plain, comprises a steep continental slope followed by the flatter continental rise. Sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope, extending as far as 500 km from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rises gradient is intermediate between the slope and the shelf, on the order of 0. 5–1°, the largest shelf – the Siberian Shelf in the Arctic Ocean – stretches to 1,500 kilometers in width. The South China Sea lies over another extensive area of shelf, the Sunda Shelf, which joins Borneo, Sumatra. Other familiar bodies of water that overlie continental shelves are the North Sea, the average width of continental shelves is about 80 km. The depth of the shelf also varies, but is limited to water shallower than 150 m. The slope of the shelf is quite low, on the order of 0. 5°, vertical relief is also minimal. Though the continental shelf is treated as a province of the ocean, it is not part of the deep ocean basin proper. Passive continental margins such as most of the Atlantic coasts have wide and shallow shelves, active continental margins have narrow, relatively steep shelves, due to frequent earthquakes that move sediment to the deep sea. The shelf usually ends at a point of increasing slope, the sea floor below the break is the continental slope. Below the slope is the rise, which finally merges into the deep ocean floor. The continental shelf and the slope are part of the continental margin, the shelf area is commonly subdivided into the inner continental shelf, mid continental shelf, and outer continental shelf, each with their specific geomorphology and marine biology. The character of the shelf changes dramatically at the shelf break, with a few exceptions, the shelf break is located at a remarkably uniform depth of roughly 140 m, this is likely a hallmark of past ice ages, when sea level was lower than it is now. The continental slope is steeper than the shelf, the average angle is 3°. The slope is cut with submarine canyons. The physical mechanisms involved in forming these canyons were not well understood until the 1960s, the continental shelves are covered by terrigenous sediments, that is, those derived from erosion of the continents

Lava
–
Lava is the molten rock expelled by a volcano during an eruption. The resulting rock after solidification and cooling is called lava. The molten rock is formed in the interior of planets, including Earth. The source of the heat melts the rock within the earth is geothermal energy. When first erupted from a vent, lava is a liquid usually at temperatures from 700 to 1,200 °C. A lava flow is an outpouring of lava, which is created during a non-explosive effusive eruption. When it has stopped moving, lava solidifies to form igneous rock, the term lava flow is commonly shortened to lava. Although lava can be up to 100,000 times more viscous than water, lava can flow great distances before cooling and solidifying because of its thixotropic, explosive eruptions produce a mixture of volcanic ash and other fragments called tephra, rather than lava flows. The word lava comes from Italian, and is derived from the Latin word labes which means a fall or slide. The first use in connection with extruded magma was apparently in an account written by Francesco Serao on the eruption of Vesuvius between May 14 and June 4,1737. Serao described a flow of lava as an analogy to the flow of water. The composition of almost all lava of the Earths crust is dominated by silicate minerals, mostly feldspars, olivine, pyroxenes, amphiboles, micas, igneous rocks, which form lava flows when erupted, can be classified into three chemical types, felsic, intermediate, and mafic. These classes are primarily chemical, however, the chemistry of lava also tends to correlate with the temperature, its viscosity. Felsic or silicic lavas such as rhyolite and dacite typically form lava spines, most silicic lava flows are extremely viscous, and typically fragment as they extrude, producing blocky autobreccias. Felsic magmas can erupt at temperatures as low as 650 to 750 °C, unusually hot rhyolite lavas, however, may flow for distances of many tens of kilometres, such as in the Snake River Plain of the northwestern United States. Intermediate or andesitic lavas are lower in aluminium and silica, and usually somewhat richer in magnesium, intermediate lavas form andesite domes and block lavas, and may occur on steep composite volcanoes, such as in the Andes. Poorer in aluminium and silica than felsic lavas, and also commonly hotter, greater temperatures tend to destroy polymerized bonds within the magma, promoting more fluid behaviour and also a greater tendency to form phenocrysts. Higher iron and magnesium tends to manifest as a darker groundmass, mafic or basaltic lavas are typified by their high ferromagnesian content, and generally erupt at temperatures in excess of 950 °C

Calabria
–
Calabria, known in antiquity as Bruttium and formerly as Italia, is a region in Southern Italy and forms the traditionally conceptualized toe of the Italian Peninsula which resembles a boot. The capital city of Calabria is Catanzaro and its most populated city, and the seat of the Regional Council of Calabria, is Reggio Calabria in the Province of Reggio Calabria. The region is bordered to the north by the Basilicata Region, to the west by the Tyrrhenian Sea, the region covers 15,080 km2 and has a population of just under 2 million. The demonym of Calabria in English is Calabrian, in ancient times Calabria was referred to as Italy. The Romans later extended the name to cover Southern Italy and then the entire peninsula, the region is a long and narrow peninsula which stretches from north to south for 248 km, with a maximum width of 110 km. Some 42% of Calabrias area, corresponding to 15,080 km2, is mountainous, 49% is hilly and it is surrounded by the Ionian and Tyrrhenian seas. It is separated from Sicily by the Strait of Messina, where the narrowest point between Capo Peloro in Sicily and Punta Pezzo in Calabria is only 3.2 km, three mountain ranges are present, Pollino, La Sila and Aspromonte. All three mountain ranges are unique with their own flora and fauna, the Pollino Mountains in the north of the region are rugged and form a natural barrier separating Calabria from the rest of Italy. Parts of the area are heavily wooded, while others are vast and these mountains are home to a rare Bosnian Pine variety, and are included in the Pollino National Park. The highest point is Botte Donato, which reaches 1,928 metres, the area boasts numerous lakes and dense coniferous forests. La Sila also has some of the tallest trees in Italy which are called the Giants of the Sila, the Sila National Park is also known to have the purest air in Europe. The Aspromonte massif forms the southernmost tip of the Italian peninsula bordered by the sea on three sides and this unique mountainous structure reaches its highest point at Montalto, at 1,995 metres, and is full of wide, man-made terraces that slope down towards the sea. In general, most of the terrain in Calabria has been agricultural for centuries. The lowest slopes are rich in vineyards and citrus fruit orchards, the Diamante citron is one of the citrus fruits. Moving upwards, olives and chestnut trees appear while in the regions there are often dense forests of oak, pine, beech. Calabrias climate is influenced by the sea and mountains, mountain areas have a typical mountainous climate with frequent snow during winter. Erratic behavior of the Tyrrhenian Sea can bring heavy rainfall on the slopes of the region, while hot air from Africa makes the east coast of Calabria dry. The mountains that run along the region also influence the climate, the east coast is much warmer and has wider temperature ranges than the west coast

Campania
–
Campania is a region in Southern Italy. Located on the Italian Peninsula, with the Mediterranean Sea to the west, it includes the small Phlegraean Islands, Campania was colonised by Ancient Greeks and was part of Magna Græcia. During the Roman era, the area maintained a Greco-Roman culture, the capital city of Campania is Naples. Campania is rich in culture, especially in regard to gastronomy, music, architecture, archeological and ancient sites such as Pompeii, Herculaneum, Paestum and Velia. The name of Campania itself is derived from Latin, as the Romans knew the region as Campania felix, the rich natural sights of Campania make it highly important in the tourism industry, especially along the Amalfi Coast, Mount Vesuvius and the island of Capri. During the 8th century BC, people from Euboea in Greece, known as Cumaeans, another Oscan tribe, the Samnites, moved down from central Italy into Campania. The Roman consul Quintus Publilius Filo recaptured Neapolis by 326 BC, the Second Samnite War ended with the Romans controlling southern Campania and additional regions further to the south. Campania was a part of the Roman Republic by the end of the 4th century BC, valued for its pastures. Its Greek language and customs made it a centre of Hellenistic civilization, during the Pyrrhic War the battle took place in Campania at Maleventum in which the Romans, led by consul Curius Dentatus, were victorious. They renamed the city Beneventum, which grew in stature until it was only to Capua in southern Italy. During the Second Punic War in 216 BC, Capua, in a bid for equality with Rome, the rebellious Capuans were isolated from the rest of Campania, which remained allies of Rome. Naples resisted Hannibal due to the imposing walls, Capua was eventually starved into submission in the Roman retaking of 211 BC, and the Romans were victorious. The rest of Campania, with the exception of Naples, adopted the Latin language as official and was Romanised. As part of the Roman Empire, Campania, with Latium, Roman Emperors chose Campania as a holiday destination, among them Claudius and Tiberius, the latter of whom is infamously linked to the island of Capri. It was also during this period that Christianity came to Campania, Two of the apostles, St. Peter and St. Paul, are said to have preached in the city of Naples, and there were also several martyrs during this time. Unfortunately, the period of calm was violently interrupted by the epic eruption of Mount Vesuvius in 79 which buried the cities of Pompeii. The area had many duchies and principalities during the Middle Ages, in the hands of the Byzantine Empire, under the Normans, the smaller independent states were brought together as part of the Kingdom of Sicily, before the mainland broke away to form the Kingdom of Naples. It was during this period elements of Spanish, French

Aegean Islands
–
The ancient Greek name of the Aegean Sea, Archipelago was later applied to the islands it contains and is now used more generally, to refer to any island group. The vast majority of the Aegean Islands belong to Greece, being split among nine administrative regions, the only sizable possessions of Turkey in the Aegean Sea are Imbros and Tenedos, in the northeastern part of the Sea. Various smaller islets off Turkeys western coast are also under Turkish sovereignty, most of the islands enjoy warm summer temperatures and cold winter influenced by the Mediterranean climate. In the Treaty of Peace in 1947, these Italian-controlled islands were ceded to Greece, media related to Islands of the Aegean Sea at Wikimedia Commons

Tyrrhenian Basin
–
The Tyrrhenian Basin is a sedimentary basin located in the western Mediterranean Sea under the Tyrrhenian Sea. It covers a 231,000 km² area that is bounded by Sardinia to the west, Corsica to the northwest, Sicily to the southeast, the Tyrrhenian basin displays an irregular seafloor marked by several seamounts and two distinct sub-basins - the Vavilov and Marsili basins. The Vavilov deep plain contains the deepest point of the Tyrrhenian basin at approximately 3785 meters, the basin trends roughly northwest-southeast with the spreading axis trending northeast-southwest. The Tyrrhenian basin is located in a complex portion of the Mediterranean Sea. The basin is partially encircled by several belts, including the Apennines to the northeast, the Alps to the north. It is also bounded by a convergent boundary and associated trench to the southeast, between the upper slope of the trench and Calabria are a number of small fore-arc basins that developed through extensional listric faulting during the Tortonian. These basins subsequently subsided between the late Pliocene and Quaternary and are now infilled with mélange, the Aeolian Islands north of Calabria and Sicily represent the volcanic arc of the convergent system. The volcanism associated with these islands occurs at the northeast closure of the downgoing slab, Tyrrhenian basement rocks consist of late Paleozoic granites derived from the Hercynian orogeny. Basement rocks in the portion of the basin were reactivated during the Alpine orogeny while those to the northwest were undisturbed. The Upper Sardinia Margin is a passive margin located northwest of the Vavilov Basin. Seismic reflection surveys across the Upper Sardinia Margin exhibit a stratigraphic geometry suggestive of pre-rift, syn-rift, at the base of the syn-rift sequence are 60 meters of Tortonian conglomerate with subrounded clasts derived from metamorphosed carbonate and quartzitic basement. It is inferred that this formation was deposited in a high-energy subaerial environment like an alluvial fan. Overlying the conglomerate formation are oyster-bearing glauconitic sandstones deposited in a nearshore environment, the boundary between the syn-rift and post-rift periods is believed to be located in a 50-meter section of late Messinian gypsum that overlays the calcareous ooze and claystone formations. At the top of the section are 243 meters of Pliocene to Pleistocene post-rift sediment containing calcareous mud with occasional terrigenous clastics. The Lower Sardinia Margin lies near the transition between continental and oceanic crust and this is the easternmost point on the margin where pre-rift, syn-rift, and post-rift sediments can be clearly discerned on seismic reflection profiles. A drill core to the base of the syn-rift sediments revealed 533 meters of thinly-bedded, calcareous, siltstone and sandstone with dispersed detrital gypsum grains and anhydrite nodules. The entire sequence is reversely magnetized, which placed in the context of the adjacent stratigraphy. Overlaying the syn-rift sediments are 200 meters of Pliocene to Pleistocene hemipelagic marine sediment with intermittent volcanic glass and this sediment layer is believed to be deposited after the end of rifting due to its subhorizontal seismic reflection profile

Ustica
–
Ustica is the name of a small island, about 9 kilometres across, situated 52 kilometres north of Capo Gallo, Italy in the Tyrrhenian Sea. Roughly 1,300 people live in the comune of the same name, there is regular ferry service from the island to Palermo, Italy. Excavations begun in 1989 at Faraglioni have unearthed what was a prehistoric village dating from the 14th to the 13th century BC. The foundations of some 300 stone-built houses were discovered, and the walls of the settlement are among the strongest fortifications of any period known in Italy. It is believed that early settlers came over from the Aeolian Islands. In historic times, the island has been populated at least since about 1500 BC by Phoenician peoples, in ancient Greece, the Island was named Osteodes in memory of the thousands of Carthaginian mutineers left there to die of hunger in the 4th century BC. The Romans renamed the island Ustica, Latin for burnt, for its black rocks, the island is also known locally as the black pearl. In the 6th century, a Benedictine community settled in the island, attempts to colonize the island in the Middle Ages failed because of raids by Barbary pirates. In the mid-18th century, the island was settled by approximately 90 people from the island of Lipari, an island located north of Sicily. They brought with them the patron saint of Lipari, Bartholomew the Apostle, in the mid- to late 19th century and early 20th century, as the population of the island grew too large, hundreds of Ustican families emigrated to the United States. Many of these settled in New Orleans and surrounding areas. A smaller number of families settled in San Jose and San Francisco, in New York, during the Fascist years in Italy and until the 1950s, Ustica was used as an island prison. Benito Mussolini banished thousands of opponents to Ustica, often as many as 1,500 at a time. Both Antonio Gramsci and Amadeo Bordiga were sent there, in the early 1940s Yugoslav war prisoners were crammed onto the island, and many of them died from malnutrition and tuberculosis. In the 1950s they were followed by suspected Mafia hoods expelled from Sicily, on June 27,1980 Aerolinee Itavia Flight 870 crashed a short distance from the island while on approach to Palermo, killing all 81 passengers and crew. The island is characterized by reduced sources of water, and the vegetation is consequently scarce, the coast has numerous rocks and grottoes. Ustica is home of the honeybee Apis mellifera sicula, Ustica is particularly known for scuba diving, with a number of diving schools established on the island. Recreational divers are attracted by the relatively deep dives, which are a feature of the volcanic geology

Urban planning
–
Urban planning is also referred to as urban and regional planning, regional planning, town planning, city planning, rural planning or some combination in various areas worldwide. It takes many forms and it can share perspectives and practices with urban design, urban planning guides orderly development in urban, suburban and rural areas. Practitioners of urban planning are concerned with research and analysis, strategic thinking, architecture, urban design, public consultation, policy recommendations, implementation and management. Urban planners work with the fields of architecture, landscape architecture, civil engineering. Early urban planners were often members of these cognate fields, today urban planning is a separate, independent professional discipline. The discipline is the category that includes different sub-fields such as land-use planning, zoning, economic development, environmental planning. There is evidence of planning and designed communities dating back to the Mesopotamian, Indus Valley, Minoan. Archeologists studying the ruins of cities in these areas find paved streets that were out at right angles in a grid pattern. The idea of a planned out urban area evolved as different civilizations adopted it, beginning in the 8th century BCE, Greek city states were primarily centered on orthogonal plans. The ancient Romans, inspired by the Greeks, also used orthogonal plans for their cities, city planning in the Roman world was developed for military defense and public convenience. The spread of the Roman Empire subsequently spread the ideas of urban planning, as the Roman Empire declined, these ideas slowly disappeared. However, many cities in Europe still held onto the planned Roman city center, cities in Europe from the 9th to 14th centuries, often grew organically and sometimes chaotically. But many hundreds of new towns were built according to preconceived plans. Most of these were realized from the 12th to 14th centuries, from the 15th century on, much more is recorded of urban design and the people that were involved. In this period, theoretical treatises on architecture and urban planning start to appear in which questions are addressed and designs of towns. During the Enlightenment period, several European rulers ambitiously attempted to redesign capital cities, during the Second French Republic, Baron Georges-Eugène Haussmann, under the direction of Napoleon III, redesigned the city of Paris into a more modern capital, with long, straight, wide boulevards. Planning and architecture went through a shift at the turn of the 20th century. The industrialized cities of the 19th century grew at a tremendous rate, the pace and style of this industrial construction was largely dictated by the concerns of private business

Peloritani
–
The Peloritani are a mountain range of north-eastern Sicily, in southern Italy, extending for some 65 km from Capo Peloro to the Nebrodi Mountains. On the north and west they are bordered by the Tyrrhenian and Ionian Seas, respectively, the highest peaks are the Montagna Grande, the Rocca di Novara, the Pizzo di Vernà, the Monte Poverello and the Monte Scuderi. The range is made up of a series of peaks, with an average height of 800–1,000 m. The deep gorges house numerous streams that create the typical rivers of this land called Fiumare, the most common rocks are of igneous and metamorphic origin. Of unusual origin are the rocks of the Argimusco plateau. Several pine woods have been reconstituted by the local authorities starting from the 1950s, an ancient path named Dorsale dei Peloritani goes through all its ridge line starting from Monte Dinnammare above the Strait of Messina until the Rocca di Novara

Obsidian
–
Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. It is produced when felsic lava extruded from a volcano cools rapidly with minimal crystal growth, Obsidian is commonly found within the margins of rhyolitic lava flows known as obsidian flows, where the chemical composition induces a high viscosity and polymerization degree of the lava. The inhibition of atomic diffusion through this highly viscous and polymerized lava explains the lack of crystal growth. Obsidian is hard and brittle, it therefore fractures with very sharp edges, which were used in the past in cutting and piercing tools, among the various forms of glass we may reckon Obsidian glass, a substance very similar to the stone found by Obsidius in Ethiopia. Obsidian is the rock formed as a result of quickly cooled lava, tektites were once thought by many to be obsidian produced by lunar volcanic eruptions, though few scientists now adhere to this hypothesis. Obsidian is mineral-like, but not a true mineral because as a glass it is not crystalline, in addition and it is sometimes classified as a mineraloid. Though obsidian is usually dark in color similar to mafic rocks such as basalt, Obsidian consists mainly of SiO2, usually 70% or more. Crystalline rocks with obsidians composition include granite and rhyolite, because obsidian is metastable at the Earths surface, no obsidian has been found that is older than Cretaceous age. This breakdown of obsidian is accelerated by the presence of water, having a low water content when newly formed, typically less than 1% water by weight, obsidian becomes progressively hydrated when exposed to groundwater, forming perlite. Pure obsidian is usually dark in appearance, though the color varies depending on the presence of impurities, iron and other transition elements may give the obsidian a dark brown to black color. Very few samples are nearly colorless, in some stones, the inclusion of small, white, radially clustered crystals of cristobalite in the black glass produce a blotchy or snowflake pattern. Obsidian may contain patterns of gas bubbles remaining from the lava flow and these bubbles can produce interesting effects such as a golden sheen. An iridescent, rainbow-like sheen is caused by inclusions of magnetite nanoparticles, Obsidian can be found in locations which have experienced rhyolitic eruptions. Obsidian can also be found in the eastern U. S. states of Virginia, as well as Pennsylvania, there are only four major deposit areas in the central Mediterranean, Lipari, Pantelleria, Palmarola and Monte Arci. Ancient sources in the Aegean were Milos and Gyali, acıgöl town and the Göllü Dağ volcano were the most important sources in central Anatolia, one of the more important source areas in the prehistoric Near East. Use of obsidian in pottery of the Neolithic in the area around Lipari was found to be less at a distance representing two weeks journeying. Anatolian sources of obsidian are known to have been the used in the Levant. The first attested civilized use is from excavations at Tell Brak dated the late fifth millennia, Obsidian was valued in Stone Age cultures because, like flint, it could be fractured to produce sharp blades or arrowheads

Metal
–
A metal is a material that is typically hard, opaque, shiny, and has good electrical and thermal conductivity. Metals are generally malleable—that is, they can be hammered or pressed permanently out of shape without breaking or cracking—as well as fusible and ductile, about 91 of the 118 elements in the periodic table are metals, the others are nonmetals or metalloids. Some elements appear in both metallic and non-metallic forms, astrophysicists use the term metal to collectively describe all elements other than hydrogen and helium, the simplest two, in a star. The star fuses smaller atoms, mostly hydrogen and helium, to larger ones over its lifetime. In that sense, the metallicity of an object is the proportion of its matter made up of all chemical elements. Many elements and compounds that are not normally classified as metals become metallic under high pressures, the atoms of metallic substances are typically arranged in one of three common crystal structures, namely body-centered cubic, face-centered cubic, and hexagonal close-packed. In bcc, each atom is positioned at the center of a cube of eight others, in fcc and hcp, each atom is surrounded by twelve others, but the stacking of the layers differs. Some metals adopt different structures depending on the temperature, atoms of metals readily lose their outer shell electrons, resulting in a free flowing cloud of electrons within their otherwise solid arrangement. This provides the ability of metallic substances to easily transmit heat, while this flow of electrons occurs, the solid characteristic of the metal is produced by electrostatic interactions between each atom and the electron cloud. This type of bond is called a metallic bond, Metals are usually inclined to form cations through electron loss, reacting with oxygen in the air to form oxides over various timescales. Examples,4 Na + O2 →2 Na2O2 Ca + O2 →2 CaO4 Al +3 O2 →2 Al2O3, the transition metals are slower to oxidize because they form a passivating layer of oxide that protects the interior. Others, like palladium, platinum and gold, do not react with the atmosphere at all, some metals form a barrier layer of oxide on their surface which cannot be penetrated by further oxygen molecules and thus retain their shiny appearance and good conductivity for many decades. The oxides of metals are generally basic, as opposed to those of nonmetals, exceptions are largely oxides with very high oxidation states such as CrO3, Mn2O7, and OsO4, which have strictly acidic reactions. Painting, anodizing or plating metals are good ways to prevent their corrosion, however, a more reactive metal in the electrochemical series must be chosen for coating, especially when chipping of the coating is expected. Water and the two form an electrochemical cell, and if the coating is less reactive than the coatee. Metals in general have high conductivity, high thermal conductivity. Typically they are malleable and ductile, deforming under stress without cleaving, in terms of optical properties, metals are shiny and lustrous. Sheets of metal beyond a few micrometres in thickness appear opaque, although most metals have higher densities than most nonmetals, there is wide variation in their densities, lithium being the least dense solid element and osmium the densest

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

Mycenae
–
Mycenae is an archaeological site in Greece, located about 90 kilometres southwest of Athens, in the north-eastern Peloponnese. Argos is 11 kilometres to the south, Corinth,48 kilometres to the north, from the hill on which the palace was located, one can see across the Argolid to the Saronic Gulf. In the second millennium BC, Mycenae was one of the centres of Greek civilization. The period of Greek history from about 1600 BC to about 1100 BC is called Mycenaean in reference to Mycenae, at its peak in 1350 BC, the citadel and lower town had a population of 30,000 and an area of 32 hectares. Although the citadel was built by Greeks, the name Mukanai is thought not to be Greek, legend has it that the name was connected to the Greek word mycēs. Thus, Pausanias ascribes the name to the legendary founder Perseus, the earliest written form of the name is Mykēnē, which is found in Homer. The reconstructed Mycenaean Greek name of the site is Mukānai, which has the form of a plural like Athānai, the change of ā to ē in more recent versions of the name is the result of a well-known sound change in later Attic-Ionic. An EH–MH settlement was discovered near a well on top of the Kalkani hill southwest of the acropolis. The first burials in pits or cist graves manifest in the MH period on the west slope of the acropolis, during the Bronze Age, the pattern of settlement at Mycenae was a fortified hill surrounded by hamlets and estates, in contrast to the dense urbanity on the coast. Richer grave goods mark the burials as possibly regal, mounds over the top contained broken drinking vessels and bones from a repast, testifying to a more than ordinary farewell. A walled enclosure, Grave Circle A, included six more shaft graves, with nine female, eight male, Grave goods were more costly than in Circle B. The presence of engraved and inlaid swords and daggers, with points and arrowheads, leave little doubt that warrior chieftains. Some art objects obtained from the graves are the Silver Siege Rhyton, the Mask of Agamemnon, the Cup of Nestor, Alan Wace divided the nine tholos tombs of Mycenae into three groups of three, each based on architecture. His earliest – the Cyclopean Tomb, Epano Phournos, and the Tomb of Aegisthus – are dated to LHIIA, burial in tholoi is seen as replacing burial in shaft graves. The care taken to preserve the shaft graves testifies that they were by then part of the royal heritage, being more visible, the tholoi all had been plundered either in antiquity, or in later historic times. Within these walls, much of which can still be seen, the final palace, remains of which are currently visible on the acropolis of Mycenae, dates to the start of LHIIIA,2. Earlier palaces must have existed, but they had cleared away or built over. The construction of palaces at that time with an architecture was general throughout southern Greece

British Isles
–
The British Isles are a group of islands off the north-western coast of continental Europe that consist of the islands of Great Britain, Ireland and over six thousand smaller isles. Situated in the North Atlantic, the islands have an area of approximately 315,159 km2. Two sovereign states are located on the islands, Ireland and the United Kingdom of Great Britain, the oldest rocks in the group are in the north west of Scotland, Ireland and North Wales and are 2,700 million years old. During the Silurian period the north-western regions collided with the south-east, the topography of the islands is modest in scale by global standards. Ben Nevis rises to an elevation of only 1,344 metres, and Lough Neagh, the climate is temperate marine, with mild winters and warm summers. The North Atlantic Drift brings significant moisture and raises temperatures 11 °C above the average for the latitude. This led to a landscape which was dominated by temperate rainforest. The region was re-inhabited after the last glacial period of Quaternary glaciation, Ireland, which became an island by 12,000 BC, was not inhabited until after 8000 BC. Great Britain became an island by 5600 BC, Hiberni, Pictish and Britons tribes, all speaking Insular Celtic, inhabited the islands at the beginning of the 1st millennium AD. Much of Brittonic-controlled Britain was conquered by the Roman Empire from AD43, the first Anglo-Saxons arrived as Roman power waned in the 5th century and eventually dominated the bulk of what is now England. Viking invasions began in the 9th century, followed by permanent settlements. Most of Ireland seceded from the United Kingdom after the Irish War of Independence, the term British Isles is controversial in Ireland, where there are objections to its usage due to the association of the word British with Ireland. The Government of Ireland does not recognise or use the term, as a result, Britain and Ireland is used as an alternative description, and Atlantic Archipelago has had limited use among a minority in academia, while British Isles is still commonly employed. Within them, they are sometimes referred to as these islands. The earliest known references to the islands as a group appeared in the writings of sea-farers from the ancient Greek colony of Massalia. The original records have been lost, however, later writings, e. g. Avienuss Ora maritima, in the 1st century BC, Diodorus Siculus has Prettanikē nēsos, the British Island, and Prettanoi, the Britons. Strabo used Βρεττανική, and Marcian of Heraclea, in his Periplus maris exteri, historians today, though not in absolute agreement, largely agree that these Greek and Latin names were probably drawn from native Celtic-language names for the archipelago. Along these lines, the inhabitants of the islands were called the Πρεττανοί, the shift from the P of Pretannia to the B of Britannia by the Romans occurred during the time of Julius Caesar

Italic peoples
–
The Italic peoples were an Indo-European ethnolinguistic group identified by speaking Italic languages. The Italics were all the peoples who spoke an idiom belonging to the Italic branch of the Indo-European languages and had settled in the Italian peninsula. The first Italic tribes, the Latino-Falisci, entered Italy across the eastern Alpine passes into the plain of the Po River about 1200 BC, later, they crossed the Apennine Mountains and eventually occupied the region of Latium, which included the area of Rome. Before 1000 BC, the Osco-Umbrians followed, which divided into various groups and gradually moved to central. According to David W. Anthony, between 3100–2800/–2600 BCE, a real folk migration of Proto-Indo-European speakers from the Yamna culture took place into the Danube Valley and these migrations probably split off Pre-Italic, Pre-Celtic and Pre-Germanic from Proto-Indo-European. Hydronymy shows that Proto-Germanic homeland is in Central Germany, which would be close to the homeland of Italic and Celtic languages as well. The origin of a hypothetical ancestral Italo-Celtic people is to be found in todays eastern Hungary and this is further confirmed by the fact that Germanic language family shares more vocabulary with the Italic family than with the Celtic language family. Remains of the prehistoric age have been found in Liguria. The most famous is perhaps that of Ötzi the Iceman, the mummy of a hunter found in the Similaun glacier in South Tyrol. During the Copper Age, at the time as metalworking appeared. Approximatively four waves of population from north to the Alps have been hypothesized on the basis of archaeological evidence, the Remedello culture is associated by some with the first identified wave of Proto-Indo-Europeans who entered Italy and took over the Po Valley. In the mid-2nd millennium BC, the Terramare culture developed in the Po Valley, the Terramare culture takes its name from the black earth residue of settlement mounds, which have long served the fertilizing needs of local farmers. The Latino-Faliscan people have associated with this culture, especially by the archaeologist Luigi Pigorini. The Proto-Villanovans practiced cremation and buried the ashes of their dead in pottery urns of a distinctive double-cone shape, the most important settlements excavated are those of Frattesina in Veneto region, Bismantova in Emilia-Romagna and near the Monti della Tolfa, north of Rome. The Osco-Umbrians, the Veneti, and possibly the Latino-Faliscans too, have associated with this culture. In the early Iron Age, the relatively homogeneous Proto-Villanovan culture shows a process of fragmentation, in Tuscany and in part of Emilia-Romagna, Latium and Campania, the Proto-Villanovan culture was followed by the Villanovan culture. The earliest remains of Villanovan culture date back to approx, in the region south of the Tiber, the Latial culture of the Latins emerges, while in the north-east of the peninsula the Este culture of the Veneti appeared. This corresponds with the emergence of the Terni culture, which had similarities with the Celtic cultures of Hallstatt
40.
Ausones
–
Ausones, the original Greek form for the Latin Aurunci, was a name applied by Greek writers to describe various Italic peoples inhabiting the southern and central regions of Italy. The usage, by ancient writers, in regard to national appellations is very vague and fluctuating, nevertheless, it does not appear that the name Aurunci was ever employed by the Romans in the vague and extensive sense in which that of Ausones was used by the Greeks. Further, it appears, by the period of the fourth century BC. Evidently two parts of one people, both dwelling on the frontiers of Latium and Campania, for more details on this see Aurunci. It is possible the Ausonians may have also been identical with the Oscans, aristotle expressly states that the part of Italy towards Tyrrhenia was inhabited by the Opicans, who were called, both formerly and in his time, by the additional name of Ausones. Antiochus of Syracuse stated, that Campania was at first occupied by the Opicans, hecataeus also appears to have held the same view with Antiochus, as he called Nola in Campania a city of the Ausones. Polybius, on the contrary, regarded the two nations as different, and spoke of Campania as inhabited by the Ausonians and Opicans. This does not necessarily prove that they were distinct, as some authors mention the Opicans and Oscans as if they were two different nations when they are clearly the same. However, the use of Ausones as identical with that of the Opicans may simply be due to the fact Ausones was used as a term for all inhabitants of the Italian peninsula. Other accounts, however, represent them as originally an inland people, scymnus Chius also writes of them as occupying an inland region, and Strabo states that they had occupied the mountain tract above the Pontine marshes, and in Roman history only with Volscians. Hellanicus according to Dionysius wrote of the Ausonians as crossing over into Sicily under their king Siculus, where the people meant are clearly the Siculi. Again, Strabo wrote of Temesa as founded by the Ausones, where he must probably mean the Oenotrians and it was probably only adopted by the Alexandrian writers as a poetical equivalent for Italia, a name which is not found in any poets of that period. From them the name of Ausonia was adopted by the Roman poets in the same sense, the etymology of the name of Ausones is uncertain, but it seems not improbable that it is originally connected with the same root as Oscus or Opicus. The first Greek settlers found Italy inhabited by three populations, Ausones, Oenotrians and Iapyges. The Ausones spoke an Indo-European language and were present in Italy at least from the 17th century BC. The core of the Ausonian people lived in a territory called Ausonia, in the 8th century BC it included what is now southern Lazio, at this period they were certainly an inconsiderable tribe, and were able to offer but little resistance to the Roman arms. According to different classical sources the Ausones were also settled in Calabria, the Ausones entered in contact with the Romans, allying against them with the Samnites. The main Ausonian cities of Ausona, Minturnae, Vescia and Sinuessa, according to a legend told by Diodorus Siculus, The King of the Ausones was Auson, son of Ulysses and Circe
41.
Aeolus
–
Aeolus, a name shared by three mythical characters, was the ruler of the winds in Greek mythology. These three personages are often difficult to tell apart, and even the ancient mythographers appear to have been perplexed about which Aeolus was which, Diodorus Siculus made an attempt to define each of these three, and his opinion is followed here. All three men named Aeolus appear to be connected genealogically, although the relationship, especially regarding the second. This Aeolus was son of Hellen and the nymph Orseis, described as the ruler of Aeolia and held to be the founder of the Aeolic branch of the Greek nation, this Aeolus married Enarete, daughter of Deimachus. Aeolus and Enarete had many children, although the precise number, other sons included Deioneus, Perieres, Cercaphas and perhaps Magnes and Aethlius. Another son is named Mimas, who provides a link to the third Aeolus in a genealogy that seems very contrived, calyce, Peisidice, Perimede and Alcyone were counted among the daughters of Aeolus and Enarete. This Aeolus also had a daughter named Arne, begotten on Melanippe. This Arne became the mother of the second Aeolus, by the god Poseidon and this Aeolus was a son of Poseidon by Arne, daughter of Aeolus. He had a brother named Boeotus. Arne confessed to her father that she was with child by the god Poseidon, her father, however, did not believe her, and handed her over to a man named Metapontus, King of Icaria. When Bœotus and Aeolus were born, they were raised by Metapontus, although his home has been traditionally identified as one of the Aeolian Islands, near Sicily, an alternative location has been suggested at Gramvousa off the northwest coast of Crete. Aeolus had six sons and six daughters, whom in Homer he wed to one another, other late accounts claim that Macareus had a daughter named Amphissa, beloved by Apollo. This Aeolus is most frequently conflated with Aeolus, the son of Poseidon and it is difficult to differentiate this Aeolus from the second Aeolus, as their identities seem to have been merged by many ancient writers. The father of this third Aeolus is given as Hippotes, son of Mimas, according to some accounts, Hippotes married the same Melanippe who was the mother of Arne. This Aeolus lived on the island of Aeolia and was visited by Odysseus. He gave hospitality for a month and provided for a west wind to carry them home and he also provided a gift of a bag containing all winds but the west, which Odysseuss crew members unwittingly opened just before they were to reach Ithaca. Unfortunately, they were back to Aeolia, where Aeolus refused to provide any further help, because he believed that their short. This Aeolus was perceived by post-Homeric authors as a god, rather than as a mortal, like the previous, this Aeolus was said to have had twelve children - six sons and six daughters

Odyssey
–
The Odyssey is one of two major ancient Greek epic poems attributed to Homer. It is, in part, a sequel to the Iliad, the Odyssey is fundamental to the modern Western canon, and is the second-oldest extant work of Western literature, the Iliad is the oldest. Scholars believe the Odyssey was composed near the end of the 8th century BC, somewhere in Ionia, the poem mainly focuses on the Greek hero Odysseus, king of Ithaca, and his journey home after the fall of Troy. It takes Odysseus ten years to reach Ithaca after the ten-year Trojan War. In his absence, it is assumed Odysseus has died, and his wife Penelope and son Telemachus must deal with a group of suitors, the Mnesteres or Proci. The Odyssey continues to be read in the Homeric Greek and translated into languages around the world. Many scholars believe the poem was composed in an oral tradition by an aoidos, perhaps a rhapsode. The details of the ancient oral performance and the conversion to a written work inspire continual debate among scholars. The Odyssey was written in a dialect of Greek—a literary amalgam of Aeolic Greek, Ionic Greek. Among the most noteworthy elements of the text are its non-linear plot, in the English language as well as many others, the word odyssey has come to refer to an epic voyage. The Odyssey has a lost sequel, the Telegony, which was not written by Homer and it was usually attributed in antiquity to Cinaethon of Sparta. In one source, the Telegony was said to have stolen from Musaeus by either Eugamon or Eugammon of Cyrene. The Odyssey begins ten years after the end of the ten-year Trojan War, and Odysseus has still not returned home from the war. Odysseus protectress, the goddess Athena, requests to Zeus, king of the gods, to finally allow Odysseus to return home when Odysseus enemy, then, disguised as a Taphian chieftain named Mentes, she visits Telemachus to urge him to search for news of his father. He offers her hospitality, they observe the suitors dining rowdily while the bard Phemius performs a poem for them. Penelope objects to Phemius theme, the Return from Troy, because it reminds her of her missing husband and that night Athena, disguised as Telemachus, finds a ship and crew for the true prince. The next morning, Telemachus calls an assembly of citizens of Ithaca to discuss what should be done with the suitors. Accompanied by Athena, he departs for the Greek mainland and the household of Nestor, most venerable of the Greek warriors at Troy, now at home in Pylos
43.
Homer
–
Homer is the name ascribed by the ancient Greeks to the semi-legendary author of the Iliad and the Odyssey, two epic poems which are the central works of Greek literature. The Odyssey focuses on the home of Odysseus, king of Ithaca. Many accounts of Homers life circulated in classical antiquity, the most widespread being that he was a bard from Ionia. The modern scholarly consensus is that these traditions do not have any historical value, the Homeric question - by whom, when, where and under what circumstances were the Iliad and Odyssey composed - continues to be debated. Broadly speaking, modern scholarly opinion on the authorship question falls into two camps, one group holds that most of the Iliad and the Odyssey is the work of a single poet of genius. The other considers the Homeric poems to be the crystallization of a process of working and re-working by many contributors and it is generally accepted that the poems were composed at some point around the late eighth or early seventh century B. C. Most researchers believe that the poems were transmitted orally. The Homeric epics were the greatest influence on ancient Greek culture and education, to Plato, the chronological period of Homer depends on the meaning to be assigned to the word Homer. Was Homer a single person, an imaginary person representing a group of poets and this information is often called the world of Homer. The Homeric period would in that cover a number of historical periods, especially the Mycenaean Age. Considered word-for-word, the texts as we know them are the product of the scholars of the last three centuries. Each edition of the Iliad or Odyssey is a different, as the editors rely on different manuscripts and fragments. The term accuracy reveals a belief in an original uniform text. The manuscripts of the work currently available date to no earlier than the 10th century. These are at the end of a missing thousand-year chain of copies made as each generation of manuscripts disintegrated or were lost or destroyed and these numerous manuscripts are so similar that a single original can be postulated. The time gap in the chain is bridged by the scholia, or notes, on the existing manuscripts, librarian of the Library of Alexandria, he had noticed a wide divergence in the works attributed to Homer, and was trying to restore a more authentic copy. He had collected several manuscripts, which he named, the Sinopic, the one he selected for correction was the koine, which Murray translates as the Vulgate. Aristarchus was known for his selection of material

Odysseus
–
Odysseus, also known by the Latin name Ulysses, was a legendary Greek king of Ithaca and the hero of Homers epic poem the Odyssey. Odysseus also plays a key role in Homers Iliad and other works in that same epic cycle. Husband of Penelope, father of Telemachus, and son of Laërtes and Anticlea, Odysseus is renowned for his brilliance, guile, and versatility and he is most famous for the Odyssey, ten eventful years he took to return home after the decade-long Trojan War. The name has several variants, in Greek the character was called Olysseus, Oulixeus, Oulixes, hence, there may originally have been two separate figures, one called something like Odysseus, the other something like Ulixes, who were combined into one complex personality. The etymology of the name is unknown, ancient authors linked the name to the Greek verbs odussomai to be wroth against, to hate, or to oduromai to lament, bewail. Homer in references and puns, relates it to various forms of this verb and it has also been suggested that the name is of non-Greek origin, probably not even Indo-European, with an unknown etymology, R. S. P. Beekes has suggested a Pre-Greek origin. In Book 19 of the Odyssey, where Odysseuss early childhood is recounted, Euryclea tries to guide him to naming the boy Polyaretos, for he has much been prayed for. Autolycus apparently in a sardonic mood, decided to give the child a name that would commemorate his own experience in life. Because I got odium upon myself before coming here, let the childs name be Odysseus to signify this. The pun was prophetic as well as commemorative, Odysseus often receives the patronymic epithet Laertiades, son of Laërtes. In the Iliad and Odyssey there are several epithets used to describe Odysseus and his name and stories were adopted into Etruscan religion under the name Uthuze. Hence, Odysseus was the great-grandson of the Olympian god Hermes, according to the Iliad and Odyssey, his father is Laertes and his mother Anticlea, although there was a non-Homeric tradition that Sisyphus was his true father. The rumor went that Laertes bought Odysseus from the conniving king, Odysseus is said to have a younger sister, Ctimene, who went to Same to be married and is mentioned by the swineherd Eumaeus, whom she grew up alongside, in Book 15 of the Odyssey. Homers Iliad and Odyssey portray Odysseus as a hero, but the Romans. In Virgils Aeneid, written between 29 and 19 BC, he is referred to as cruel Odysseus or deceitful Odysseus. Turnus, in Aeneid ix, reproaches the Trojan Ascanius with images of rugged, forthright Latin virtues, declaring, You shall not find the sons of Atreus here, nor need the frauds of sly Ulysses fear. While the Greeks admired his cunning and deceit, these qualities did not recommend themselves to the Romans, who possessed a rigid sense of honour. His attempts to avoid his sacred oath to defend Menelaus and Helen offended Roman notions of duty, the majority of sources for Odysseus pre-war exploits—principally the mythographers Pseudo-Apollodorus and Hyginus—postdate Homer by many centuries

Greeks
–
The Greeks or Hellenes are an ethnic group native to Greece, Cyprus, southern Albania, Turkey, Sicily, Egypt and, to a lesser extent, other countries surrounding the Mediterranean Sea. They also form a significant diaspora, with Greek communities established around the world, many of these regions coincided to a large extent with the borders of the Byzantine Empire of the late 11th century and the Eastern Mediterranean areas of ancient Greek colonization. The cultural centers of the Greeks have included Athens, Thessalonica, Alexandria, Smyrna, most ethnic Greeks live nowadays within the borders of the modern Greek state and Cyprus. The Greek genocide and population exchange between Greece and Turkey nearly ended the three millennia-old Greek presence in Asia Minor, other longstanding Greek populations can be found from southern Italy to the Caucasus and southern Russia and Ukraine and in the Greek diaspora communities in a number of other countries. Today, most Greeks are officially registered as members of the Greek Orthodox Church, the Greeks speak the Greek language, which forms its own unique branch within the Indo-European family of languages, the Hellenic. They are part of a group of ethnicities, described by Anthony D. Smith as an archetypal diaspora people. Both migrations occur at incisive periods, the Mycenaean at the transition to the Late Bronze Age, the Mycenaeans quickly penetrated the Aegean Sea and, by the 15th century BC, had reached Rhodes, Crete, Cyprus and the shores of Asia Minor. Around 1200 BC, the Dorians, another Greek-speaking people, followed from Epirus, the Dorian invasion was followed by a poorly attested period of migrations, appropriately called the Greek Dark Ages, but by 800 BC the landscape of Archaic and Classical Greece was discernible. The Greeks of classical antiquity idealized their Mycenaean ancestors and the Mycenaean period as an era of heroes, closeness of the gods. The Homeric Epics were especially and generally accepted as part of the Greek past, as part of the Mycenaean heritage that survived, the names of the gods and goddesses of Mycenaean Greece became major figures of the Olympian Pantheon of later antiquity. The ethnogenesis of the Greek nation is linked to the development of Pan-Hellenism in the 8th century BC, the works of Homer and Hesiod were written in the 8th century BC, becoming the basis of the national religion, ethos, history and mythology. The Oracle of Apollo at Delphi was established in this period, the classical period of Greek civilization covers a time spanning from the early 5th century BC to the death of Alexander the Great, in 323 BC. It is so named because it set the standards by which Greek civilization would be judged in later eras, the Peloponnesian War, the large scale civil war between the two most powerful Greek city-states Athens and Sparta and their allies, left both greatly weakened. Many Greeks settled in Hellenistic cities like Alexandria, Antioch and Seleucia, two thousand years later, there are still communities in Pakistan and Afghanistan, like the Kalash, who claim to be descended from Greek settlers. The Hellenistic civilization was the period of Greek civilization, the beginnings of which are usually placed at Alexanders death. This Hellenistic age, so called because it saw the partial Hellenization of many non-Greek cultures and this age saw the Greeks move towards larger cities and a reduction in the importance of the city-state. These larger cities were parts of the still larger Kingdoms of the Diadochi, Greeks, however, remained aware of their past, chiefly through the study of the works of Homer and the classical authors. An important factor in maintaining Greek identity was contact with barbarian peoples and this led to a strong desire among Greeks to organize the transmission of the Hellenic paideia to the next generation
