Which ancient Greek poem gives the fullest surviving account of Pandora’s story?

Works and Days gives the fullest surviving account of Pandora’s story. The poem is traditionally attributed to Hesiod and combines farming advice, moral instruction, myths, and reflections on justice and human labor.

Its Pandora passage describes Zeus ordering Hephaestus to make a woman from earth. The gods then provide her with gifts, and Hermes takes her to Epimetheus. After Pandora opens the large storage jar, evils spread among humanity, while hope remains inside. This is the source of many details repeated in modern summaries.

Hesiod also mentions Pandora in Theogony, but that poem gives a shorter account connected with Prometheus and the punishment of human beings. Theogony is therefore an important related source, not the fullest narrative. Neither poem uses the modern English phrase “Pandora’s box”; the original story refers to a pithos, a large jar.
