Greek mythology is the body of myths originally told by the ancient Greeks, and a genre of ancient Greek folklore, today absorbed alongside Roman mythology into the broader designation of classical mythology. These stories concern the ancient Greek religion's view of the origin and nature of the world; the lives and activities of deities, heroes, and mythological creatures; and the origins and significance of the ancient Greeks' cult and ritual practices. Modern scholars study the myths to shed light on the religious and political institutions of ancient Greece, and to better understand the nature of myth-making itself.

Prometheus (1868 by Gustave Moreau). The myth of Prometheus first was attested by Hesiod and then constituted the basis for a tragic trilogy of plays, possibly by Aeschylus, consisting of Prometheus Bound, Prometheus Unbound, and Prometheus Pyrphoros.
The Roman poet Virgil, here depicted in the fifth-century manuscript, the Vergilius Romanus, preserved details of Greek mythology in many of his writings.

Myth is a genre of folklore or theology consisting primarily of narratives that play a fundamental role in a society, such as foundational tales or origin myths. For scholars, this is very different from the vernacular usage of the term "myth" that simply refers to something that is not true. Instead, the truth value of a myth is not a defining criterion.
