Hesiod describes Pandora’s creation in both Theogony and Works and Days.
Hesiod was an early Greek poet generally dated to the late eighth or early seventh century BCE. His Theogony presents a genealogy and history of the gods, while Works and Days combines moral instruction, farming advice, myths, and reflections on justice.
The accounts differ in emphasis. Theogony briefly connects the creation of woman with Zeus’s punishment of humanity after Prometheus’s theft of fire. Works and Days gives the fuller narrative: the gods equip Pandora with gifts, and Zeus sends her to Epimetheus, whose acceptance leads to the opening of the jar.
Hesiod is the earliest surviving literary source for the Pandora story. That does not prove he invented every element; Greek myths circulated orally before being written down. The commonly used phrase “Pandora’s box” also reflects later translation and retelling rather than Hesiod’s original wording.
