Dolphin is a common name of aquatic mammals within the order Cetacea, arbitrarily excluding whales and porpoises. The term dolphin refers to the extant families Delphinidae, Platanistidae and Pontoporiidae, the extinct Lipotidae. There are 40 extant species named as dolphins. Dolphins range in size from the 1.7 m long and 50 kg Maui's dolphin to the 9.5 m and 10 t killer whale. Several species exhibit sexual dimorphism, they have two limbs that are modified into flippers. Though not quite as flexible as seals, some dolphins can travel at 55.5 km/h. Dolphins use their conical shaped teeth to capture fast moving prey, they have well-developed hearing, adapted for both air and water and is so well developed that some can survive if they are blind. Some species are well adapted for diving to great depths, they have a layer of blubber, under the skin to keep warm in the cold water. Although dolphins are widespread, most species prefer the warmer waters of the tropic zones, but some, like the right whale dolphin, prefer colder climates.
Dolphins feed on fish and squid, but a few, like the killer whale, feed on large mammals, like seals. Male dolphins mate with multiple females every year, but females only mate every two to three years. Calves are born in the spring and summer months and females bear all the responsibility for raising them. Mothers of some species fast and nurse their young for a long period of time. Dolphins produce a variety of vocalizations in the form of clicks and whistles. Dolphins are sometimes hunted in places such as Japan, in an activity known as dolphin drive hunting. Besides drive hunting, they face threats from bycatch, habitat loss, marine pollution. Dolphins have been depicted in various cultures worldwide. Dolphins feature in literature and film, as in the film series Free Willy. Dolphins are sometimes trained to perform tricks; the most common dolphin species in captivity is the bottlenose dolphin, while there are around 60 captive killer whales. The name is from Greek δελφίς, "dolphin", related to the Greek δελφύς, "womb".
The animal's name can therefore be interpreted as meaning "a'fish' with a womb". The name was transmitted via the Latin delphinus, which in Medieval Latin became dolfinus and in Old French daulphin, which reintroduced the ph into the word; the term mereswine has historically been used. The term'dolphin' can be used to refer to, under the parvorder Odontoceti, all the species in the family Delphinidae and the river dolphin families Iniidae, Pontoporiidae and Platanistidae; this term has been misused in the US in the fishing industry, where all small cetaceans are considered porpoises, while the fish dorado is called dolphin fish. In common usage the term'whale' is used only for the larger cetacean species, while the smaller ones with a beaked or longer nose are considered'dolphins'; the name'dolphin' is used casually as a synonym for bottlenose dolphin, the most common and familiar species of dolphin. There are six species of dolphins thought of as whales, collectively known as blackfish: the killer whale, the melon-headed whale, the pygmy killer whale, the false killer whale, the two species of pilot whales, all of which are classified under the family Delphinidae and qualify as dolphins.
Though the terms'dolphin' and'porpoise' are sometimes used interchangeably, porpoises are not considered dolphins and have different physical features such as a shorter beak and spade-shaped teeth. Porpoises share a common ancestry with the Delphinidae. A group of dolphins is called a "school" or a "pod". Male dolphins are called "bulls", females "cows" and young dolphins are called "calves".

NASU Institute of Archaeology
The Institute of Archaeology of the National Academy of Science of Ukraine is a research institute in Ukraine, part of the National Academy of Sciences of Ukraine. It is a main institution with the academy that conducts research in a field of studying archaeology and ancient history of Ukraine; the institute is part of department of history and law of the National Academy of Sciences of Ukraine. The institute's headquarters is located in Obolonskyi District, near the Dnieper embankment; the institute was created in 1938 after reorganization of the institute of history of material culture of the Academy of Sciences of the Ukrainian SSR. In 1938–1993 the institute governed the Olbia excavation site as one of its departments. At its current located in Obolon, the institute is since 1996 to which it arrived from the Vydubychi Monastery. After its relocation the institute has reorganized again consisting of 11 departments and in 2005 there was added one more department. In 2014 the institute was accounted for 133 researchers among which academician Petro Tolochko, corresponding members of the National Academy of Sciences of Ukraine Serhiy Kryzhytskyi, Oleksandr Motsya, Hlib Ivakin, Viktor Chabai and 16 more scientists with a degree of doctor of sciences.
Due to the 2014 Russian aggression against Ukraine and the Russian annexation of Crimea, many scientists were forced to leave the peninsula. The 2014 Russian authorities liquidated the Crimean branch of the Institute of Archaeology; the Ukrainian activist Dmytro Tymchuk noted that archaeologists who illegally conduct excavations are being tracked and will be charged with it eventually. Since April of 2014 the Russian Academy of Sciences and the Russian Hermitage Museum has illegally sent numerous archaeological expeditions for excavations in Crimea. Official website Tolochko, P.

Smyrna was a Greek city dating back to antiquity located at a central and strategic point on the Aegean coast of Anatolia. Since 1930, the modern city located there has been known as İzmir, in Turkey, the Turkish rendering of the same name. Due to its advantageous port conditions, its ease of defense and its good inland connections, Smyrna rose to prominence. Two sites of the ancient city are today within the boundaries of İzmir; the first site founded by indigenous peoples, rose to prominence during the Archaic Period as one of the principal ancient Greek settlements in western Anatolia. The second, whose foundation is associated with Alexander the Great, reached metropolitan proportions during the period of the Roman Empire. Most of the present-day remains of the ancient city date from the Roman era, the majority from after a 2nd-century AD earthquake. In practical terms, a distinction is made between these. Old Smyrna was the initial settlement founded around the 11th century BC, first as an Aeolian settlement, taken over and developed during the Archaic Period by the Ionians.
Smyrna proper was the new city which residents moved to as of the 4th century BC and whose foundation was inspired by Alexander the Great. Old Smyrna was located on a small peninsula connected to the mainland by a narrow isthmus at the northeastern corner of the inner Gulf of İzmir, at the edge of a fertile plain and at the foot of Mount Yamanlar; this Anatolian settlement commanded the gulf. Today, the archeological site, named Bayraklı Höyüğü, is 700 metres inland, in the Tepekule neighbourhood of Bayraklı at 38°27′51″N 27°10′13″E. New Smyrna developed on the slopes of the Mount Pagos and alongside the coastal strait below where a small bay existed until the 18th century; the core of the late Hellenistic and early Roman Smyrna is preserved in the large area of İzmir Agora Open Air Museum at this site. Research is being pursued at the sites of both the new cities; this has been conducted since 1997 for Old Smyrna and since 2002 for the Classical Period city, in collaboration between the İzmir Archaeology Museum and the Metropolitan Municipality of İzmir.
For further information on etymology of the city's name, see İzmir#Names and etymology. Several explanations have been offered for its name. A Greek myth derived the name from an eponymous Amazon named "Σμύρνα", the name of a quarter of Ephesus; this is the basis of a city of Aeolis. In inscriptions and coins, the name was written as "Ζμύρνα", "Ζμυρναῖος", "of Smyrna"; the name Smyrna may have been taken from the ancient Greek word for myrrh, "smyrna", the chief export of the city in ancient times. The region was settled at least as of the beginning of the third millennium BC, or earlier, as the recent finds in Yeşilova Höyük suggests, it could have been a city of the autochthonous Leleges before the Greek colonists started to settle along the coast of Asia Minor as of the beginning of the first millennium BC. Throughout antiquity Smyrna was a leading city-state of Ionia, with influence over the Aegean shores and islands. Smyrna was among the cities that claimed Homer as a resident; the early Aeolian Greek settlers of Lesbos and Cyme, expanding eastwards, occupied the valley of Smyrna.
It was one of the confederacy of Aeolian city-states, marking the Aeolian frontier with the Ionian colonies. Strangers or refugees from the Ionian city of Colophon settled in the city. During an uprising in 688 BC, they took control of the city, making it the thirteenth of the Ionian city-states. Revised mythologies said. In 688 BC, the Ionian boxer Onomastus of Smyrna won the prize at Olympia, but the coup was then a recent event; the Colophonian conquest is mentioned by Mimnermus, who counts himself of Colophon and of Smyrna. The Aeolic form of the name was retained in the Attic dialect, the epithet "Aeolian Smyrna" remained current long after the conquest. Smyrna was located at the mouth of the small river Hermus and at the head of a deep arm of the sea that reached far inland; this enabled Greek trading ships to sail into the heart of Lydia, making the city part of an essential trade route between Anatolia and the Aegean. During the 7th century BC, Smyrna rose to splendor. One of the great trade routes which cross Anatolia descends the Hermus valley past Sardis, diverging from the valley, passes south of Mount Sipylus and crosses a low pass into the little valley where Smyrna lies between the mountains and the sea.
Miletus and Ephesus were situated at the sea end of the other great trade route across Anatolia. The Meles River, which flowed by Smyrna, was worshiped in the valley. A common and consistent tradition connects Homer with the valley of Smyrna and the banks of the Meles; the epithet Melesigenes was applied to him. The steady equable flow of the Meles, alike in summer and winter, its short course and ending near the city, are celebrated by Aristides and Himerius; the stream rises from abundant springs east of the city and flows into the southeast extremity of the gulf. The archaic city contained a temple of Athena from the 7th century BC; when the Mermnad kings raised the Lydian power and aggressiveness, Smyr
Herodotus was an ancient Greek historian, born in Halicarnassus in the Persian Empire. He is known for having written the book The Histories, a detailed record of his "inquiry" on the origins of the Greco-Persian Wars, he is considered to have been the first writer to have treated historical subjects using a method of systematic investigation—specifically, by collecting his materials and critically arranging them into an historiographic narrative. On account of this, he is referred to as "The Father of History", a title first conferred on him by the first-century BC Roman orator Cicero. Despite Herodotus's historical significance, little is known about his personal life, his Histories deals with the lives of Croesus, Cambyses, Smerdis and Xerxes and the battles of Marathon, Artemisium, Salamis and Mycale. Herodotus has been criticized for the fact that his book includes a large number of obvious legends and fanciful accounts. Many authors, starting with the late fifth-century BC historian Thucydides, have accused him of making up stories for entertainment.
Herodotus, states that he is reporting what he has been told. A sizable portion of the information he provides has since been confirmed by historians and archaeologists. Herodotus announced the purpose and scope of his work at the beginning of his Histories as such: Here are presented the results of the enquiry carried out by Herodotus of Halicarnassus; the purpose is to prevent the traces of human events from being erased by time, to preserve the fame of the important and remarkable achievements produced by both Greeks and non-Greeks. His record of the achievements of others was an achievement in itself, though the extent of it has been debated. Herodotus's place in history and his significance may be understood according to the traditions within which he worked, his work is the earliest Greek prose. However, Dionysius of Halicarnassus, a literary critic of Augustan Rome, listed seven predecessors of Herodotus, describing their works as simple, unadorned accounts of their own and other cities and people, Greek or foreign, including popular legends, sometimes melodramatic and naïve charming – all traits that can be found in the work of Herodotus himself.
Modern historians regard the chronology as uncertain, but according to the ancient account, these predecessors included Dionysius of Miletus, Charon of Lampsacus, Hellanicus of Lesbos, Xanthus of Lydia and, the best attested of them all, Hecataeus of Miletus. Of these, only fragments of Hecataeus's works survived, the authenticity of these is debatable, but they provide a glimpse into the kind of tradition within which Herodotus wrote his own Histories. In his introduction to Hecataeus's work, Genealogies: Hecataeus the Milesian speaks thus: I write these things as they seem true to me; this points forward to the "international" outlook typical of Herodotus. However, one modern scholar has described the work of Hecataeus as "a curious false start to history", since despite his critical spirit, he failed to liberate history from myth. Herodotus mentions Hecataeus in his Histories, on one occasion mocking him for his naive genealogy and, on another occasion, quoting Athenian complaints against his handling of their national history.
It is possible that Herodotus borrowed much material from Hecataeus, as stated by Porphyry in a quote recorded by Eusebius. In particular, it is possible that he copied descriptions of the crocodile and phoenix from Hecataeus's Circumnavigation of the Known World misrepresenting the source as "Heliopolitans", but Hecataeus did not record events that had occurred in living memory, unlike Herodotus, nor did he include the oral traditions of Greek history within the larger framework of oriental history. There is no proof that Herodotus derived the ambitious scope of his own work, with its grand theme of civilizations in conflict, from any predecessor, despite much scholarly speculation about this in modern times. Herodotus claims to be better informed than his predecessors by relying on empirical observation to correct their excessive schematism. For example, he argues for continental asymmetry as opposed to the older theory of a circular earth with Europe and Asia/Africa equal in size. However, he retains idealizing tendencies, as in his symmetrical notions of the Nile.
His debt to previous authors of prose "histories" might be questionable, but there is no doubt that Herodotus owed much to the example and inspiration of poets and story-tellers. For example, Athenian tragic poets provided him with a world-view of a balance between conflicting forces, upset by the hubris of kings, they provided his narrative with a model of episodic structure, his familiarity with Athenian tragedy is demonstrated in a number of passages echoing Aeschylus's Persae, including the epigrammatic observation that the defeat of the Persian navy at Salamis caused the defeat of the land army. The debt may have been repaid by Sophocles because there appear to be echoes of The Histories in his plays a passage in Antigone that resembles Herodotus's account of the death of Intaphernes. However, this point is one of the most contentious
The Greeks or Hellenes are an ethnic group native to Greece, southern Albania, Turkey, Egypt and, to a lesser extent, other countries surrounding the Mediterranean Sea. They form a significant diaspora, with Greek communities established around the world. Greek colonies and communities have been established on the shores of the Mediterranean Sea and Black Sea, but the Greek people have always been centered on the Aegean and Ionian seas, where the Greek language has been spoken since the Bronze Age; until the early 20th century, Greeks were distributed between the Greek peninsula, the western coast of Asia Minor, the Black Sea coast, Cappadocia in central Anatolia, the Balkans and Constantinople. 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, Alexandria and Constantinople at various periods. Most ethnic Greeks live nowadays within the borders of 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 registered as members of the Greek Orthodox Church. Greeks have influenced and contributed to culture, exploration, philosophy, architecture, mathematics and technology, business and sports, both and contemporarily; 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 classical ethnicities, described by Anthony D. Smith as an "archetypal diaspora people"; the Proto-Greeks arrived at the area now called Greece, in the southern tip of the Balkan peninsula, at the end of the 3rd millennium BC. The sequence of migrations into the Greek mainland during the 2nd millennium BC has to be reconstructed on the basis of the ancient Greek dialects, as they presented themselves centuries and are therefore subject to some uncertainties.
There were at least two migrations, the first being the Ionians and Aeolians, which resulted in Mycenaean Greece by the 16th century BC, the second, the Dorian invasion, around the 11th century BC, displacing the Arcadocypriot dialects, which descended from the Mycenaean period. Both migrations occur at incisive periods, the Mycenaean at the transition to the Late Bronze Age and the Doric at the Bronze Age collapse. An alternative hypothesis has been put forth by linguist Vladimir Georgiev, who places Proto-Greek speakers in northwestern Greece by the Early Helladic period, i.e. towards the end of the European Neolithic. Linguists Russell Gray and Quentin Atkinson in a 2003 paper using computational methods on Swadesh lists have arrived at a somewhat earlier estimate, around 5000 BC for Greco-Armenian split and the emergence of Greek as a separate linguistic lineage around 4000 BC. In c. 1600 BC, the Mycenaean Greeks borrowed from the Minoan civilization its syllabic writing system and developed their own syllabic script known as Linear B, providing the first and oldest written evidence of Greek.
The Mycenaeans penetrated the Aegean Sea and, by the 15th century BC, had reached Rhodes, Crete and the shores of Asia Minor. Around 1200 BC, the Dorians, another Greek-speaking people, followed from Epirus. Traditionally, historians have believed that the Dorian invasion caused the collapse of the Mycenaean civilization, but it is the main attack was made by seafaring raiders who sailed into the eastern Mediterranean around 1180 BC; 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 a glorious era of heroes, closeness of the gods and material wealth; the Homeric Epics were and accepted as part of the Greek past and it was not until the time of Euhemerism that scholars began to question Homer's historicity. 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 antiquity.
The ethnogenesis of the Greek nation is linked to the development of Pan-Hellenism in the 8th century BC. According to some scholars, the foundational event was the Olympic Games in 776 BC, when the idea of a common Hellenism among the Greek tribes was first translated into a shared cultural experience and Hellenism was a matter of common culture; the works of Homer and Hesiod were written in the 8th century BC, becoming the basis of the national religion, ethos 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 eras; the Classical period is described as the "Golden Age" of Greek civilization, and
Greece the Hellenic Republic, self-identified and known as Hellas, is a country located in Southern and Southeast Europe, with a population of 11 million as of 2016. Athens is largest city, followed by Thessaloniki. Greece is located at the crossroads of Europe and Africa. Situated on the southern tip of the Balkan Peninsula, it shares land borders with Albania to the northwest, North Macedonia and Bulgaria to the north, Turkey to the northeast; the Aegean Sea lies to the east of the mainland, the Ionian Sea to the west, the Cretan Sea and the Mediterranean Sea to the south. Greece has the longest coastline on the Mediterranean Basin and the 11th longest coastline in the world at 13,676 km in length, featuring a large number of islands, of which 227 are inhabited. Eighty percent of Greece is mountainous, with Mount Olympus being the highest peak at 2,918 metres; the country consists of nine geographic regions: Macedonia, Central Greece, the Peloponnese, Epirus, the Aegean Islands, Thrace and the Ionian Islands.
Greece is considered the cradle of Western civilisation, being the birthplace of democracy, Western philosophy, Western literature, political science, major scientific and mathematical principles, Western drama and notably the Olympic Games. From the eighth century BC, the Greeks were organised into various independent city-states, known as poleis, which spanned the entire Mediterranean region and the Black Sea. Philip of Macedon united most of the Greek mainland in the fourth century BC, with his son Alexander the Great conquering much of the ancient world, from the eastern Mediterranean to India. Greece was annexed by Rome in the second century BC, becoming an integral part of the Roman Empire and its successor, the Byzantine Empire, in which Greek language and culture were dominant. Rooted in the first century A. D. the Greek Orthodox Church helped shape modern Greek identity and transmitted Greek traditions to the wider Orthodox World. Falling under Ottoman dominion in the mid-15th century, the modern nation state of Greece emerged in 1830 following a war of independence.
Greece's rich historical legacy is reflected by its 18 UNESCO World Heritage Sites. The sovereign state of Greece is a unitary parliamentary republic and developed country with an advanced high-income economy, a high quality of life, a high standard of living. A founding member of the United Nations, Greece was the tenth member to join the European Communities and has been part of the Eurozone since 2001, it is a member of numerous other international institutions, including the Council of Europe, the North Atlantic Treaty Organization, the Organisation for Economic Co-operation and Development, the World Trade Organization, the Organization for Security and Co-operation in Europe, the Organisation internationale de la Francophonie. Greece's unique cultural heritage, large tourism industry, prominent shipping sector and geostrategic importance classify it as a middle power, it is the largest economy in the Balkans. The names for the nation of Greece and the Greek people differ from the names used in other languages and cultures.
The Greek name of the country is Hellas or Ellada, its official name is the Hellenic Republic. In English, the country is called Greece, which comes from Latin Graecia and means'the land of the Greeks'; the earliest evidence of the presence of human ancestors in the southern Balkans, dated to 270,000 BC, is to be found in the Petralona cave, in the Greek province of Macedonia. All three stages of the stone age are represented for example in the Franchthi Cave. Neolithic settlements in Greece, dating from the 7th millennium BC, are the oldest in Europe by several centuries, as Greece lies on the route via which farming spread from the Near East to Europe. Greece is home to the first advanced civilizations in Europe and is considered the birthplace of Western civilisation, beginning with the Cycladic civilization on the islands of the Aegean Sea at around 3200 BC, the Minoan civilization in Crete, the Mycenaean civilization on the mainland; these civilizations possessed writing, the Minoans writing in an undeciphered script known as Linear A, the Mycenaeans in Linear B, an early form of Greek.
The Mycenaeans absorbed the Minoans, but collapsed violently around 1200 BC, during a time of regional upheaval known as the Bronze Age collapse. This ushered from which written records are absent. Though the unearthed Linear B texts are too fragmentary for the reconstruction of the political landscape and can't support the existence of a larger state contemporary Hittite and Egyptian records suggest the presence of a single state under a "Great King" based in mainland Greece; the end of the Dark Ages is traditionally dated to the year of the first Olympic Games. The Iliad and the Odyssey, the foundational texts of Western literature, are believed to have been composed by Homer in the 7th or 8th centuries BC. With the end of the Dark Ages, there emerged various kingdoms and city-states across the Greek peninsula, which spread to the shores of the Black Sea, So
Ancient Greece was a civilization belonging to a period of Greek history from the Greek Dark Ages of the 12th–9th centuries BC to the end of antiquity. Following this period was the beginning of the Early Middle Ages and the Byzantine era. Three centuries after the Late Bronze Age collapse of Mycenaean Greece, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and colonization of the Mediterranean Basin; this was followed by the period of Classical Greece, an era that began with the Greco-Persian Wars, lasting from the 5th to 4th centuries BC. Due to the conquests by Alexander the Great of Macedon, Hellenistic civilization flourished from Central Asia to the western end of the Mediterranean Sea; the Hellenistic period came to an end with the conquests and annexations of the eastern Mediterranean world by the Roman Republic, which established the Roman province of Macedonia in Roman Greece, the province of Achaea during the Roman Empire. Classical Greek culture philosophy, had a powerful influence on ancient Rome, which carried a version of it to many parts of the Mediterranean Basin and Europe.
For this reason, Classical Greece is considered to be the seminal culture which provided the foundation of modern Western culture and is considered the cradle of Western civilization. Classical Greek culture gave great importance to knowledge. Science and religion were not separate and getting closer to the truth meant getting closer to the gods. In this context, they understood the importance of mathematics as an instrument for obtaining more reliable knowledge. Greek culture, in a few centuries and with a limited population, managed to explore and make progress in many fields of science, mathematics and knowledge in general. Classical antiquity in the Mediterranean region is considered to have begun in the 8th century BC and ended in the 6th century AD. Classical antiquity in Greece was preceded by the Greek Dark Ages, archaeologically characterised by the protogeometric and geometric styles of designs on pottery. Following the Dark Ages was the Archaic Period, beginning around the 8th century BC.
The Archaic Period saw early developments in Greek culture and society which formed the basis for the Classical Period. After the Archaic Period, the Classical Period in Greece is conventionally considered to have lasted from the Persian invasion of Greece in 480 until the death of Alexander the Great in 323; the period is characterized by a style, considered by observers to be exemplary, i.e. "classical", as shown in the Parthenon, for instance. Politically, the Classical Period was dominated by Athens and the Delian League during the 5th century, but displaced by Spartan hegemony during the early 4th century BC, before power shifted to Thebes and the Boeotian League and to the League of Corinth led by Macedon; this period saw the Greco-Persian Wars and the Rise of Macedon. Following the Classical period was the Hellenistic period, during which Greek culture and power expanded into the Near and Middle East; this period ends with the Roman conquest. Roman Greece is considered to be the period between Roman victory over the Corinthians at the Battle of Corinth in 146 BC and the establishment of Byzantium by Constantine as the capital of the Roman Empire in AD 330.
Late Antiquity refers to the period of Christianization during the 4th to early 6th centuries AD, sometimes taken to be complete with the closure of the Academy of Athens by Justinian I in 529. The historical period of ancient Greece is unique in world history as the first period attested directly in proper historiography, while earlier ancient history or proto-history is known by much more circumstantial evidence, such as annals or king lists, pragmatic epigraphy. Herodotus is known as the "father of history": his Histories are eponymous of the entire field. Written between the 450s and 420s BC, Herodotus' work reaches about a century into the past, discussing 6th century historical figures such as Darius I of Persia, Cambyses II and Psamtik III, alluding to some 8th century ones such as Candaules. Herodotus was succeeded by authors such as Thucydides, Demosthenes and Aristotle. Most of these authors were either Athenian or pro-Athenian, why far more is known about the history and politics of Athens than those of many other cities.
Their scope is further limited by a focus on political and diplomatic history, ignoring economic and social history. In the 8th century BC, Greece began to emerge from the Dark Ages which followed the fall of the Mycenaean civilization. Literacy had been lost and Mycenaean script forgotten, but the Greeks adopted the Phoenician alphabet, modifying it to create the Greek alphabet. Objects with Phoenician writing on them may have been available in Greece from the 9th century BC, but the earliest evidence of Greek writing comes from graffiti on Greek pottery from the mid-8th century. Greece was divided into many small self-governing communities, a pattern dictated by Greek geography: every island and plain is cut off from its neighbors by the sea or mountain ranges; the Lelantine War is the earliest documented war of the ancient Greek period. It was fought between the important poleis of Chalcis and Eretria over the fertile Lelantine plain of Euboea. Both cities seem to have suffered a decline as result of the long war, though Chalcis was the nominal victor.
A mercantile class arose in the first half of the 7th century BC, shown by the introduction of coinage in about 680 BC. This
