Hesiod also mentions Pandora in the Theogony.
The Theogony is a genealogical poem about the origins and generations of the Greek gods. Its Pandora passage is brief compared with the account in Works and Days, but it connects Pandora with the punishment imposed on humanity after Prometheus took fire for mortals.
This is why Hesiod is central to the earliest surviving literary tradition about Pandora. The two poems are different works, yet together they preserve related parts of the myth: the Theogony emphasizes divine conflict and punishment, while Works and Days gives more detail about Pandora’s creation and the vessel.
The poems are generally dated to the seventh century BCE. Although later authors expanded, altered, and illustrated the story, no surviving earlier Greek literary account has replaced Hesiod as the principal ancient source.
