In Greek mythology, the Nereids or Nereides are sea nymphs, the 50 daughters of the 'Old Man of the Sea' Nereus and the Oceanid Doris, sisters to their brother Nerites. They often accompany Poseidon, the god of the sea, and can be friendly and helpful to sailors.

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.
