Hesiod introduces Pandora by name in his poem Works and Days.
Works and Days is an ancient Greek didactic poem traditionally dated to the seventh century BCE. It combines practical advice about farming and justice with myths explaining the human condition, including the story of Pandora and the origin of troubles.
Hesiod also discusses Pandora in the Theogony, but Works and Days gives the fuller narrative surrounding her arrival among humans. In that account, Zeus uses Pandora in a punishment connected with Prometheus and fire. The poem describes divine contributions to her creation and her marriage to Epimetheus.
Readers often assume Homer must be the source because Homer is the best-known early Greek poet. However, the surviving Homeric epics do not provide the Pandora story in the form associated with Hesiod. The two poets belong to the same broad archaic Greek literary world, but Pandora’s central literary account is Hesiodic.
