Hesiod first tells Pandora’s creation story in the surviving ancient sources.
The story appears in two poems attributed to Hesiod: the Theogony and Works and Days. Hesiod was an early Greek poet traditionally dated to the late eighth or early seventh century BCE. His account presents Pandora as a punishment sent by Zeus after Prometheus deceived the gods and gave fire to humanity.
The Theogony gives a brief version, while Works and Days provides more narrative detail, including the divine gifts bestowed on Pandora and the opening of her storage vessel. The familiar English expression “Pandora’s box” reflects a later translation tradition; Hesiod’s Greek text describes a jar, not a box.
Hesiod is therefore the safest answer when asking who first records the myth in extant literature. Earlier oral stories may have circulated, but no earlier surviving written account of Pandora is known.
