Which ancient Greek poem tells the Pandora story in its fullest early form?

The ancient Greek poem that tells the Pandora story in its fullest early form is Works and Days. It is attributed to Hesiod and combines farming advice, moral instruction, myth, and reflections on justice.

The poem places Pandora within Hesiod’s account of the consequences of Prometheus’s theft of fire. Zeus has Pandora created and sends her to Epimetheus; after the jar is opened, troubles spread among human beings while hope remains inside. This version is the main ancient source behind the later “Pandora’s box” tradition.

Hesiod also mentions Pandora in the Theogony, but the two poems do not provide identical levels of detail. The Iliad and Odyssey, traditionally attributed to Homer, are major Greek epics but do not supply the canonical Pandora episode. The Argonautica is a much later epic associated with Apollonius Rhodius and is not the poem that established this story.
