Hesiod is traditionally credited with composing both Works and Days and Theogony, the key early sources for Pandora.
Hesiod is one of the earliest Greek poets whose works survive substantially. He is usually placed alongside Homer in the early archaic period, although the dates and biographies attached to him are partly traditional. His poems are written in the epic dialect and use the same broader metrical tradition associated with Greek hexameter poetry.
Theogony presents a genealogy and history of the gods, while Works and Days offers practical and moral instruction framed by myths about human life. Pandora appears briefly in Theogony and receives a fuller narrative in Works and Days. The two accounts are related but not identical in emphasis or detail.
Ancient authorship is not proven in the modern documentary sense. “Hesiod” may represent an individual poet, a traditional name, or a body of poetry shaped through transmission. Even so, standard reference works identify Hesiod as the traditional author of both poems, making him the central ancient literary source for Pandora’s story.
