The title of Hesiod’s poem that also contains a shorter Pandora account is Theogony.
Theogony is a genealogical poem about the origins and generations of the Greek gods. It includes a brief account of the creation of woman and the consequences of Prometheus’s conflict with Zeus. The Pandora narrative is developed more extensively in Hesiod’s Works and Days, but Theogony is an important related source.
The title means “birth of the gods” or “generation of the gods.” It is not an epic adventure like Homer’s Iliad or Odyssey. Readers sometimes assume that every familiar detail of Pandora comes from one single ancient text; in fact, the surviving material is distributed across works and later traditions, with translations and adaptations adding further changes.
