Which ancient Greek poem describes Pandora’s creation and the release of human troubles?

Hesiod’s Works and Days describes Pandora’s creation and the release of human troubles.

Works and Days is a didactic poem attributed to Hesiod, usually dated to the late eighth or early seventh century BCE. It combines advice about farming and justice with myths explaining the human condition, including the stories of Prometheus, Pandora, and the successive Ages of Man.

The poem presents Pandora as part of Zeus’s punishment after Prometheus gave fire to humans. The gods contribute to her appearance and abilities, and Hermes leads her to Epimetheus. After she opens the sealed vessel, hardships spread among humans, while one remaining thing stays inside.

Theogony, another poem attributed to Hesiod, discusses the conflict involving Prometheus but does not provide the fuller Pandora-and-jar narrative. That is why Works and Days is the most specific ancient literary source for the familiar episode.
