The ancient Greek poem containing the shorter Pandora account alongside Works and Days is Theogony.
Theogony is traditionally attributed to Hesiod and presents a genealogy and history of the gods. Its Pandora passage is brief: it connects the creation of the first woman with Zeus’s punishment of Prometheus and humanity. Hesiod’s Works and Days gives the fuller narrative, including the preparation of Pandora, her arrival at Epimetheus’s home, and the opening of the container.
These two poems are the earliest surviving literary sources for the Pandora myth. They do not tell exactly the same story in equal detail, which is why later summaries can unintentionally merge material from both works. Theogony focuses more on divine conflict and the consequences of Prometheus’s theft, while Works and Days develops the moral and social implications for human life.
Theogony is not a later Roman retelling, and it is not one of Homer’s epics. Its attribution to Hesiod is traditional, although ancient authorship and dating are subjects of scholarly study. The work is generally placed in the early archaic period of Greek literature.
