In which Hesiod poem is Pandora’s jar described as releasing evils into the human world?

Pandora’s jar is described as releasing evils into the human world in Hesiod’s Works and Days.

Works and Days is a didactic poem traditionally attributed to Hesiod and usually dated to the late eighth or early seventh century BCE. It combines advice about farming, justice, labor, seasons, and proper conduct with myths explaining why human life includes hardship.

Its Pandora passage says that the gods had kept troubles hidden from humans, but Pandora opened the container and allowed them to spread. Hope remained inside when she closed it. This is the source for the familiar narrative of evils escaping from Pandora’s vessel.

Hesiod also mentions Pandora in Theogony, where the emphasis is more directly on her creation and the divine order behind it. Because the two poems handle the character differently, naming the exact work matters. The modern phrase “Pandora’s box” summarizes material whose earliest surviving literary form is a jar story in Works and Days.
