Ancient Greek language in the context of Cryptographic

Classical Athens, known contemporaneously simply as Athens (Ancient Greek: Ἀθῆναι, Athênai [atʰɛ̂ːnai̯]; Modern Greek: Αθήναι, Athine [aˈθine]), was the major urban centre of the notable polis (city-state) of the same name during the classical period (480–323 BC) of ancient Greece, located in Attica, Greece, leading the Delian League in the Peloponnesian War against Sparta and the Peloponnesian League. Athenian democracy was established in 508 BC under Cleisthenes following the tyranny of Isagoras. This system remained remarkably stable, and with a few brief interruptions, it remained in place for 180 years, until 322 BC (amid the aftermath of the Lamian War). The peak of Athenian hegemony was achieved during the Age of Pericles in the 440s and 430s BC.

In the classical period, Athens was a centre for the arts, learning, and philosophy, and it was the home of Plato's Academy and Aristotle's Lyceum. Athens was also the birthplace of Socrates, Plato, Pericles, Aristophanes, Sophocles, and many other prominent philosophers, writers, and politicians of the ancient world. It is widely referred to as the cradle of Western civilization and as the birthplace of democracy, largely due to the impact of its cultural and political achievements during the 5th and 4th centuries BC on the rest of the then-known European continent.

Ancient Greece (Ancient Greek: Ἑλλάς, romanized: Hellás) was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity (c. 600 AD), that comprised a loose collection of culturally and linguistically related city-states and communities. Prior to the Roman period, most of these regions were officially unified only once under the Kingdom of Macedon from 338 to 323 BC. In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period.

Three centuries after the decline of Mycenaean Greece during the Bronze Age collapse, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical Greece, from the Greco-Persian Wars to the death of Alexander the Great in 323 BC, and which included the Golden Age of Athens and the Peloponnesian War between Athens and Sparta. The unification of Greece by Macedon under Philip II and subsequent conquest of the Achaemenid Empire by Alexander the Great spread Hellenistic civilization across the Middle East. The Hellenistic period is considered to have ended in 30 BC, when the last Hellenistic kingdom, Ptolemaic Egypt, was annexed by the Roman Republic.

Patras (/pəˈtræs, ˈpætrəs/; Greek: Πάτρα, romanized: Pátra pronounced [ˈpatra] ; Katharevousa and Ancient Greek: Πάτραι; Latin: Patrae) is Greece's third-largest city and the regional capital and largest city of Western Greece, in the northern Peloponnese, 215 km (134 mi) west of Athens. The city is built at the foot of Mount Panachaikon, overlooking the Gulf of Patras.

As of the 2021 census, the municipality of Patras has a population of 215,922, while the urban population is 173,600. The core settlement has a history spanning four millennia. In the Roman period, it had become a cosmopolitan centre of the eastern Mediterranean whilst, according to the Christian tradition, it was also the place of Saint Andrew's martyrdom.

Western philosophy refers to the philosophical thought, traditions, and works of the Western world. Historically, the term refers to the philosophical thinking of Western culture, beginning with the ancient Greek philosophy of the pre-Socratics. The word philosophy itself originated from the Ancient Greek φιλοσοφία (philosophía), literally, 'the love of wisdom', from Ancient Greek: φιλεῖν (phileîn), 'to love', and σοφία (sophía), 'wisdom'.

Western philosophy stands in contrast to other cultural and regional traditions like Eastern philosophy.

Philip II of Macedon (Ancient Greek: Φίλιππος, romanized: Phílippos; 382 BC – October 336 BC) was the king (basileus) of Macedon from 359 BC until his death in 336 BC. The rise of Macedon, from a kingdom initially at the periphery of classical Greek affairs, to a power that came to dominate Ancient Greece in the span of less than 25 years, was largely thanks to the character and policies of Philip. He was the father of Alexander the Great and a member of the ruling Argead dynasty that founded the kingdom of the Macedonians.

Philip achieved to dominate Greece during his reign by the reformation of the Macedonian army, including the establishment of the Macedonian phalanx, the use of combined arms tactics and his extensive use of siege engines and artillery, as well as by the use of effective diplomacy and marriage alliances. After defeating the Greek city-states of Athens and Thebes at the Battle of Chaeronea in 338 BC, Philip II led the effort to establish a federation of Greek states known as the Hellenic League, with him as the elected hegemon and commander-in-chief of Greece for a planned invasion of the Achaemenid Empire. However, his assassination by a royal bodyguard, Pausanias of Orestis, led to the immediate succession of his son Alexander, who would go on to invade the Achaemenid Empire in his father's stead.

Alexander III of Macedon (Ancient Greek: Ἀλέξανδρος, romanized: Aléxandros; 20/21 July 356 BC – 10/11 June 323 BC), most commonly known as Alexander the Great, was king of the ancient Greek kingdom of Macedon. He succeeded his father Philip II to the throne in 336 BC at the age of 20, and spent most of his regency conducting a lengthy military campaign throughout parts of Asia and Egypt. By the age of 30, he had created one of the largest empires in history, stretching from Greece to northwestern India. He was undefeated in battle and is widely considered to be one of history's greatest and most successful military commanders.

Alexander was tutored by Aristotle until the age of 16. In 335 BC, shortly after assuming the throne of Macedon, he launched a campaign in the Balkans and reasserted control over Thrace and parts of Illyria before marching on the city of Thebes, which was subsequently destroyed in battle. Alexander then assumed leadership of the League of Corinth, created by his father, and with his authority over all Greeks he launched a pan-Hellenic campaign to invade the Persia.

Greek (Modern Greek: ελληνικά, romanized: elliniká [eliniˈka] ; Ancient Greek: ἑλληνική, romanized: hellēnikḗ [helːɛːnikɛ́ː]) is an Indo-European language, constituting an independent Hellenic branch within the Indo-European language family. It is native to the territories that have had populations of Greeks since antiquity: Greece, Cyprus, Egypt, Italy (in Calabria and Salento), southern Albania, and other regions of the Balkans, Caucasus, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary.

The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting importance in the European canon. Greek is also the language in which many of the foundational texts in science and philosophy were originally composed. The New Testament of the Christian Bible was also originally written in Greek. Together with the Latin texts and traditions of the Roman world, the Greek texts and Greek societies of antiquity constitute the objects of study of the discipline of Classics.

Attica (Greek: Αττική, romanised: Attikí, Greek pronunciation: [atiˈci]; Ancient Greek: Ἀττική, romanised: Attikḗ, Ancient Greek pronunciation: [atːikɛ̌ː]), or the Attic Peninsula, is a historical region that encompasses the entire Athens metropolitan area, which consists of the city of Athens, the capital of Greece and the core city of the metropolitan area, as well as its surrounding suburban cities and towns. It is a peninsula projecting into the Aegean Sea, bordering on Boeotia to the north and Megaris to the west. The mines of Laurion were an important mining region located at Lavrio, on the southern tip of the peninsula.

The history of Attica is closely linked with that of Athens. In ancient times, Attica corresponded with the classical Athens city‑state. It was the most prominent region in Ancient Greece, specifically during the Golden Age of Athens in the classical period. Ancient Attica was divided into demoi, or municipalities, from the reform of Cleisthenes in 508/7 BC, grouped into three zones: urban (astu) in the region of Athens main town, and Piraeus (the port), coastal (paralia) along the coastline, and inland (mesogeia) in the interior.

In Greek mythology, Achilles (/əˈkɪliːz/ ə-KIL-eez) or Achilleus (Ancient Greek: Ἀχιλλεύς, romanized: Achilleús) was a hero of the Trojan War who was known as being the greatest of all the Greek warriors. The central character in Homer's Iliad, he was the son of the Nereid Thetis and Peleus, king of Phthia and famous Argonaut. Achilles was raised in Phthia along with his childhood companion Patroclus and received his education by the centaur Chiron. In the Iliad, he is presented as the commander of the mythical tribe of the Myrmidons.

Achilles's most notable feat during the Trojan War was the slaying of the Trojan prince Hector outside the gates of Troy. Although the death of Achilles is not presented in the Iliad, other sources concur that he was killed near the end of the Trojan War by Paris, who shot him with an arrow. Later legends (beginning with Statius's unfinished epic Achilleid, written in the first century CE) state that Achilles was invulnerable in all of his body except for one heel. According to that myth, when his mother Thetis dipped him in the river Styx as an infant, she held him by one of his heels, leaving it untouched by the waters and thus his only vulnerable body part.

Cosmology (from Ancient Greek κόσμος (cosmos) 'the universe, the world' and λογία (logia) 'study of') is a branch of physics and metaphysics dealing with the nature of the universe, the cosmos. The term cosmology was first used in English in 1656 in Thomas Blount's Glossographia, with the meaning of "a speaking of the world". In 1731, German philosopher Christian Wolff used the term cosmology in Latin (cosmologia) to denote a branch of metaphysics that deals with the general nature of the physical world. Religious or mythological cosmology is a body of beliefs based on mythological, religious, and esoteric literature and traditions of creation myths and eschatology. In the science of astronomy, cosmology is concerned with the study of the chronology of the universe.

Physical cosmology is the study of the observable universe's origin, its large-scale structures and dynamics, and the ultimate fate of the universe, including the laws of science that govern these areas. It is investigated by scientists, including astronomers and physicists, as well as philosophers, such as metaphysicians, philosophers of physics, and philosophers of space and time. Because of this shared scope with philosophy, theories in physical cosmology may include both scientific and non-scientific propositions and may depend upon assumptions that cannot be tested. Physical cosmology is a sub-branch of astronomy that is concerned with the universe as a whole. Modern physical cosmology is dominated by the Big Bang Theory which attempts to bring together observational astronomy and particle physics; more specifically, a standard parameterization of the Big Bang with dark matter and dark energy, known as the Lambda-CDM model.

Homer (/ˈhoʊmər/; Ancient Greek: Ὅμηρος [hómɛːros], Hómēros; possibly born c. the 8th century BC) was an ancient Greek poet who is credited as the author of the Iliad and the Odyssey, two epic poems that are foundational works of ancient Greek literature. Despite uncertainties about his authorship, Homer is considered one of the most influential authors in history.

The Iliad centers on a quarrel between King Agamemnon and the warrior Achilles during the last year of the Trojan War. The Odyssey chronicles the ten-year journey of Odysseus, king of Ithaca, back to his home after the fall of Troy. The epics depict man's struggle, the Odyssey especially so, as Odysseus perseveres through the punishment of the gods. The poems are in Homeric Greek, also known as Epic Greek, a literary language that shows a mixture of features of the Ionic and Aeolic dialects from different centuries; the predominant influence is Eastern Ionic. Most researchers believe that the poems were originally transmitted orally. Despite being predominantly known for their tragic and serious themes, the Homeric poems also contain instances of comedy and laughter.

The Iliad (/ˈɪliəd/ ; Ancient Greek: Ἰλιάς, romanized: Iliás, [iː.li.ás]; lit. '[a poem] about Ilion (Troy)') is one of two major ancient Greek epic poems attributed to Homer. It is one of the oldest extant works of literature still widely read by modern audiences. Like the Odyssey, the poem is divided into 24 books and was written in dactylic hexameter. It contains 15,693 lines in its most widely accepted version. The Iliad is often regarded as the first substantial piece of European literature and is a central part of the Epic Cycle.

Set toward the end of the Trojan War, a 10-year siege of the city of Troy by a coalition of Mycenaean Greek states, the poem depicts significant events in the war's final weeks. In particular, it traces the anger (μῆνις) of Achilles, a celebrated warrior, from a fierce quarrel between him and King Agamemnon, to the death of the Trojan prince Hector. The narrative moves between wide battleground scenes and more personal interactions.

The Odyssey (/ˈɒdɪsi/; Ancient Greek: Ὀδύσσεια, romanized: Odýsseia) is one of two major epics of ancient Greek literature attributed to Homer. It is one of the oldest surviving works of literature and remains popular with modern audiences. Like the Iliad, the Odyssey is divided into 24 books. It follows the heroic king of Ithaca, Odysseus, also known by the Latin variant Ulysses, and his homecoming journey after the ten-year long Trojan War. His journey from Troy to Ithaca lasts an additional ten years, during which time he encounters many perils and all of his crewmates are killed. In Odysseus's long absence, he is presumed dead, leaving his wife Penelope and son Telemachus to contend with a group of unruly suitors competing for Penelope's hand in marriage.

The Odyssey was first composed in Homeric Greek around the 8th or 7th century BC; by the mid-6th century BC, it had become part of the Greek literary canon. In antiquity, Homer's authorship was taken as true, but contemporary scholarship predominantly assumes that the Iliad and the Odyssey were composed independently, as part of long oral traditions. Given widespread illiteracy, the poem was performed for an audience by an aoidos or rhapsode.

Hesiod (/ˈhiːsiəd/ HEE-see-əd or /ˈhɛsiəd/ HEH-see-əd; Ancient Greek: Ἡσίοδος Hēsíodos; fl. c. 700 BC) was an Ancient Greek poet generally thought to have been active between 750 and 650 BC, around the same time as Homer.

Several of Hesiod's works have survived in their entirety. Among these are Theogony, which tells the origins of the gods, their lineages, and the events that led to Zeus's rise to power, and Works and Days, a poem that describes the five Ages of Man, offers advice and wisdom, and includes myths such as Pandora's box.

The Theogony (Ancient Greek: Θεογονία, romanized: Theogonía, lit. 'the genealogy or birth of the gods') is a poem by Hesiod (8th–7th century BC) describing the origins and genealogies of the Greek gods, composed c. 730–700 BC. It is written in the epic dialect of Ancient Greek and contains 1,022 lines. It is one of the most important sources for the understanding of early Greek cosmology.

Works and Days (Ancient Greek: Ἔργα καὶ Ἡμέραι, romanized: Érga kaì Hēmérai) is a didactic poem written by ancient Greek poet Hesiod around 700 BC. It is in dactylic hexameter and contains 828 lines. At its center, the Works and Days is a farmer's almanac in which Hesiod instructs his brother Perses in the agricultural arts.

The Homeric Hymns (Ancient Greek: Ὁμηρικοὶ ὕμνοι, romanised: Homērikoì húmnoi) are a collection of thirty-three ancient Greek hymns and one epigram. The hymns praise deities of the Greek pantheon and retell mythological stories, often involving a deity's birth, their acceptance among the gods on Mount Olympus, or the establishment of their cult. In antiquity, the hymns were generally, though not universally, attributed to the poet Homer: modern scholarship has established that most date to the seventh and sixth centuries BCE, though some are more recent and the latest, the Hymn to Ares, may have been composed as late as the fifth century CE.

The Homeric Hymns share compositional similarities with the Iliad and the Odyssey, also traditionally attributed to Homer. They share the same artificial literary dialect of Greek, are composed in dactylic hexameter, and make use of short, repeated phrases known as formulae. It is unclear how far writing, as opposed to oral composition, was involved in their creation. They may initially have served as preludes to the recitation of longer poems, and have been performed, at least originally, by singers accompanying themselves on a lyre or another stringed instrument. Performances of the hymns may have taken place at sympotic banquets, religious festivals and royal courts.

The Epic Cycle (Ancient Greek: Ἐπικὸς Κύκλος, romanized: Epikòs Kýklos) was a collection of Ancient Greek epic poems, composed in dactylic hexameter and related to the story of the Trojan War, including the Cypria, the Aethiopis, the so-called Little Iliad, the Iliupersis, the Nostoi, and the Telegony. Scholars sometimes include the two Homeric epics, the Iliad and the Odyssey, among the poems of the Epic Cycle, but the term is more often used to specify the non-Homeric poems as distinct from the Homeric ones.

Unlike the Iliad and the Odyssey, the cyclic epics survive only in fragments and summaries from Late Antiquity and the Byzantine period.

Ancient Greek comedy (Ancient Greek: κωμῳδία, romanized: kōmōidía) was one of the final three principal dramatic forms in the theatre of classical Greece; the others being tragedy and the satyr play. Greek comedy was distinguished from tragedy by its happy endings and use of comically exaggerated character archetypes, the latter feature being the origin of the modern concept of the comedy. Athenian comedy is conventionally divided into three periods; Old Comedy survives today largely in the form of the eleven extant plays of Aristophanes; Middle Comedy is largely lost and preserved only in relatively short fragments by authors such as Athenaeus of Naucratis; New Comedy is known primarily from the substantial papyrus fragments of Menander. A burlesque dramatic form that blended tragic and comic elements, known as phlyax play or hilarotragedy, developed in the Greek colonies of Magna Graecia by the late 4th century BC.

The philosopher Aristotle wrote in his Poetics (c. 335 BC) that comedy is a representation of laughable people and involves some kind of blunder or ugliness which does not cause pain or disaster. C. A. Trypanis wrote that comedy is the last of the great species of poetry Greece gave to the world.

Plutarch (/ˈpluːtɑːrk/; Ancient Greek: Πλούταρχος, Ploútarchos, Koine Greek: [ˈplúːtarkʰos]; c. AD 40 – 120s) was a Greek and later Roman Middle Platonist philosopher, historian, biographer, essayist, and priest at the Temple of Apollo in Delphi. He is known primarily for his Parallel Lives, a series of biographies of illustrious Greeks and Romans, and Moralia, a collection of essays and speeches. Upon becoming a Roman citizen, he was possibly named Lucius Mestrius Plutarchus (Λούκιος Μέστριος Πλούταρχος).
