Hesiod tells the Pandora story in Works and Days.
Works and Days is an ancient Greek didactic poem traditionally attributed to Hesiod, who probably lived around the late eighth or early seventh century BCE. The poem combines advice about farming, justice, labor, and proper conduct with myths explaining the human condition.
Its Pandora episode follows the story of Prometheus and the theft of fire. Zeus responds by having the gods create Pandora and by sending hardship to humanity. The poem describes her container and the evils that escape from it, making it the principal surviving source for the familiar myth.
Hesiod also mentions Pandora in the Theogony, but the fuller narrative appears in Works and Days. Homer is sometimes guessed because he is the best-known early Greek poet, yet the Pandora story is specifically associated with Hesiodic poetry.
