Archaeological findings provide a principal source of detail about Greek mythology, with gods and heroes featured prominently in the decoration of many artifacts. Geometric designs on pottery of the eighth century BC depict scenes from the Trojan cycle as well as the adventures of Heracles. In the succeeding Archaic, Classical, and Hellenistic periods, Homeric and various other mythological scenes appear, supplementing the existing literary evidence. Greek mythology has had an extensive influence on the culture, arts, and literature of Western civilization and remains part of Western heritage and language. Poets and artists from ancient times to the present have derived inspiration from Greek mythology and have discovered contemporary significance and relevance in the themes
Mythical narration plays an important role in nearly every genre of Greek literature. Nevertheless, the only general mythographical handbook to survive from Greek antiquity was the Library of Pseudo-Apollodorus. This work attempts to reconcile the contradictory tales of the poets and provides a grand summary of traditional Greek mythology and heroic legends. Apollodorus of Athens lived from c. 180–125 BC and wrote on many of these topics. His writings may have formed the basis for the collection; however the "Library" discusses events that occurred long after his death, hence the name Pseudo-Apollodorus.
Among the earliest literary sources are Homer's two epic poems, the Iliad and the Odyssey. Other poets completed the "epic cycle", but these later and lesser poems now are lost almost entirely. Despite their traditional name, the "Homeric Hymns" have no direct connection with Homer. They are choral hymns from the earlier part of the so-called Lyric age. Hesiod, a possible contemporary with Homer, offers in his Theogony (Origin of the Gods) the fullest account of the earliest Greek myths, dealing with the creation of the world; the origin of the gods, Titans, and Giants; as well as elaborate genealogies, folktales, and etiological myths. Hesiod's Works and Days, a didactic poem about farming life, also includes the myths of Prometheus, Pandora, and the Five Ages. The poet gives advice on the best way to succeed in a dangerous world, rendered yet more dangerous by its gods.
Lyrical poets often took their subjects from myth, but their treatment became gradually less narrative and more allusive. Greek lyric poets including Pindar, Bacchylides, Simonides, and bucolic poets such as Theocritus and Bion, relate individual mythological incidents. Additionally, myth was central to classical Athenian drama. The tragic playwrights Aeschylus, Sophocles, and Euripides took most of their plots from myths of the age of heroes and the Trojan War. Many of the great tragic stories (e.g. Agamemnon and his children, Oedipus, Jason, Medea, etc.) took on their classic form in these tragedies. The comic playwright Aristophanes also used myths, in The Birds and The Frogs.
Historians Herodotus and Diodorus Siculus, and geographers Pausanias and Strabo, who traveled throughout the Greek world and noted the stories they heard, supplied numerous local myths and legends, often giving little-known alternative versions. Herodotus in particular, searched the various traditions presented him and found the historical or mythological roots in the confrontation between Greece and the East. Herodotus attempted to reconcile origins and the blending of differing cultural concepts.
