Hesiod wrote both Works and Days and Theogony.
Hesiod is one of the two foundational Greek poets of the archaic period, alongside Homer. He is traditionally placed around the late eighth or early seventh century BCE. Works and Days contains the complete surviving account of Pandora opening the storage jar, while Theogony presents a genealogy and origin story of the gods and briefly includes Pandora.
The two poems have different purposes. Theogony organizes divine generations and explains the rise of Zeus, whereas Works and Days focuses on justice, labor, farming, and the hard conditions of human life. Their connection makes Hesiod central to the study of Pandora’s myth.
Little about Hesiod’s biography is certain beyond information suggested by the poems and later tradition. Scholars also debate details of authorship and composition, but the standard attribution of both works is to Hesiod. Homer is sometimes confused with him because both are early Greek poets.
