In which ancient Greek poem does Hesiod give the fullest account of Pandora?

Hesiod gives the fullest account of Pandora in Works and Days.

The poem includes the story after its discussion of Prometheus and the theft of fire. Zeus orders the gods to create Pandora, she is equipped with divine gifts, and she is sent to Epimetheus. After the vessel is opened, suffering spreads among humans while hope remains inside.

Theogony, another poem attributed to Hesiod, also refers to Pandora but gives a much shorter account. Works and Days supplies the narrative detail most readers associate with the myth, including the warning connected with Prometheus and Epimetheus.

Works and Days is not solely a mythological poem. It is also a didactic work about farming, justice, labor, seafaring, and proper conduct. The Pandora episode supports its broader explanation of why human life involves toil and hardship.
