Hesiod first gives the full creation story of Pandora in Works and Days. The poem, usually dated to the seventh century BCE, describes Pandora’s fashioning by the gods and her role in the spread of human suffering.
Hesiod is one of the earliest known Greek poets, alongside Homer, but the Pandora narrative is especially associated with his Works and Days. The poem combines advice about farming and justice with myths explaining the human condition, including the ages of humanity, Prometheus’s theft of fire, and Pandora’s arrival.
Pandora also appears in Hesiod’s Theogony, but that work gives a briefer account rather than the extended narrative found in Works and Days. This distinction makes Hesiod the strongest answer when asking where the complete story appears.
Later writers, artists, and filmmakers changed details, including the vessel’s shape and Pandora’s motivations. Those adaptations are influential, but the basic literary source for the creation episode is Hesiod’s archaic Greek poetry.
