Ancient Greek literature

Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. Modern science is typically divided into two – or three – major branches: the natural sciences, which study the physical world, and the social sciences, which study individuals and societies. While referred to as the formal sciences, the study of logic, mathematics, and theoretical computer science are typically regarded as separate because they rely on deductive reasoning instead of the scientific method as their main methodology. Meanwhile, applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine.

The history of science spans the majority of the historical record, with the earliest identifiable predecessors to modern science dating to the Bronze Age in Egypt and Mesopotamia (c. 3000–1200 BCE). Their contributions to mathematics, astronomy, and medicine entered and shaped the Greek natural philosophy of classical antiquity and later medieval scholarship, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes; while further advancements, including the introduction of the Hindu–Arabic numeral system, were made during the Golden Age of India and Islamic Golden Age. The recovery and assimilation of Greek works and Islamic inquiries into Western Europe during the Renaissance revived natural philosophy, which was later transformed by the Scientific Revolution that began in the 16th century as new ideas and discoveries departed from previous Greek conceptions and traditions. The scientific method soon played a greater role in the acquisition of knowledge, and in the 19th century, many of the institutional and professional features of science began to take shape, along with the changing of "natural philosophy" to "natural science".

The history of science covers the development of science from ancient times to the present. It encompasses all three major branches of science: natural, social, and formal. Protoscience, early sciences, and natural philosophies such as alchemy and astrology that existed during the Bronze Age, Iron Age, classical antiquity and the Middle Ages, declined during the early modern period after the establishment of formal disciplines of science in the Age of Enlightenment.

The earliest roots of scientific thinking and practice can be traced to Ancient Egypt and Mesopotamia during the 3rd and 2nd millennia BCE. These civilizations' contributions to mathematics, astronomy, and medicine influenced later Greek natural philosophy of classical antiquity, wherein formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Latin-speaking Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but continued to thrive in the Greek-speaking Byzantine Empire. Aided by translations of Greek texts, the Hellenistic worldview was preserved and absorbed into the Arabic-speaking Muslim world during the Islamic Golden Age. The recovery and assimilation of Greek works and Islamic inquiries into Western Europe from the 10th to 13th century revived the learning of natural philosophy in the West. Traditions of early science were also developed in ancient India and separately in ancient China, the Chinese model having influenced Vietnam, Korea and Japan before Western exploration. Among the Pre-Columbian peoples of Mesoamerica, the Zapotec civilization established their first known traditions of astronomy and mathematics for producing calendars, followed by other civilizations such as the Maya.

The Trojan War was a legendary conflict in Greek mythology that took place around the twelfth or thirteenth century BC. The war was waged by the Achaeans (Greeks) against the city of Troy after Paris of Troy took Helen from her husband Menelaus, king of Sparta. The war is one of the most important events in Greek mythology, and it has been narrated through many works of Greek literature, most notably Homer's Iliad. The core of the Iliad (Books II – XXIII) describes a period of four days and two nights in the tenth year of the decade-long siege of Troy; the Odyssey describes the journey home of Odysseus, one of the war's heroes. Other parts of the war are described in a cycle of epic poems, which have survived through fragments. Episodes from the war provided material for Greek tragedy and other works of Greek literature, and for Roman poets including Virgil and Ovid.

The ancient Greeks believed that Troy was located near the Dardanelles and that the Trojan War was a historical event of the twelfth or thirteenth century BC. By the mid-nineteenth century AD, both the war and the city were widely seen as non-historical, but in 1868, the German archaeologist Heinrich Schliemann met Frank Calvert, who convinced Schliemann that Troy was at what is now Hisarlık in modern-day Turkey. On the basis of excavations conducted by Schliemann and others, this claim is now accepted by most scholars.

Greek literature (Greek: Ελληνική Λογοτεχνία) dates back from the ancient Greek literature, beginning in 800 BC, to the modern Greek literature of today.

Ancient Greek literature was written in an Ancient Greek dialect, literature ranges from the oldest surviving written works until works from approximately the fifth century AD. This time period is divided into the Preclassical, Classical, Hellenistic, and Roman periods. Preclassical Greek literature primarily revolved around myths and include the works of Homer; the Iliad and the Odyssey. The Classical period saw the dawn of drama and history. Three philosophers are especially notable: Socrates, Plato, and Aristotle. During the Roman era, significant contributions were made in a variety of subjects, including history, philosophy, and the sciences.

The study of Roman sculpture is complicated by its relation to Greek sculpture. Many examples of even the most famous Greek sculptures, such as the Apollo Belvedere and Barberini Faun, are known only from Roman Imperial or Hellenistic "copies". At one time, this imitation was taken by art historians as indicating a narrowness of the Roman artistic imagination, but, in the late 20th century, Roman art began to be reevaluated on its own terms: some impressions of the nature of Greek sculpture may in fact be based on Roman artistry.

The strengths of Roman sculpture are in portraiture, where they were less concerned with the ideal than the Greeks or Ancient Egyptians, and produced very characterful works, and in narrative relief scenes. Examples of Roman sculpture are abundantly preserved, in total contrast to Roman painting, which was very widely practiced but has almost all been lost. Latin and some Greek authors, particularly Pliny the Elder in Book 34 of his Natural History, describe statues, and a few of these descriptions match extant works. While a great deal of Roman sculpture, especially in stone, survives more or less intact, it is often damaged or fragmentary; life-size bronze statues are much more rare as most have been recycled for their metal.

Ancient Greek funerary practices are attested widely in literature, the archaeological record, and in ancient Greek art. Finds associated with burials are an important source for ancient Greek culture, though Greek funerals are not as well documented as those of the ancient Romans.

Byzantine literature is the Greek literature of the Middle Ages, whether written in the Byzantine Empire or outside its borders. It was marked by a linguistic diglossy; two distinct forms of Byzantine Greek were used, a scholarly dialect based on Attic Greek, and a vernacular based on Koine Greek. Most scholars consider 'literature' to include all medieval Greek texts, but some define it with specific constraints. Byzantine literature is the successor to Ancient Greek literature and forms the basis of Modern Greek literature, although it overlaps with both periods.

The tradition saw the competing influences of Hellenism, Christianity, and earlier in the empire's history, Paganism. There was a general flourishing of gnomai, hagiography, sermons, and particularly historiography, which became less individual-focused. Poetry was often limited to musical hymnal forms, or the more niche epigram tradition, while ancient dramas and epics became obsolete. The influential romantic epic Digenes Akritas is a major exception.

Ancient Greek art is the visual and applied arts, as well as the architecture, produced by the Hellenes or Greek peoples from the start of the Iron Age to the Hellenistic period, ending with Roman conquest of Greece at the Battle of Corinth in 146 BCE. It stands out among that of other ancient cultures for its development of naturalistic but idealized depictions of the human body, in which largely nude male figures were generally the focus of innovation. The rate of stylistic development between about 750 and 300 BC was remarkable by ancient standards, and in surviving works is best seen in sculpture. There were important innovations in painting, which have to be essentially reconstructed due to the lack of original survivals of quality, other than the distinct field of painted pottery.

Greek architecture, technically very simple, established a harmonious style with numerous detailed conventions that were largely adopted by Roman architecture and are still followed in some modern buildings. It used a vocabulary of ornament that was shared with pottery, metalwork and other media, and had an enormous influence on Eurasian art, especially after Buddhism carried it beyond the expanded Greek world created by Alexander the Great. The social context of Greek art included radical political developments and a great increase in prosperity; the equally impressive Greek achievements in philosophy, literature and other fields are well known.
