Hesiod links Pandora’s jar with the origin of human suffering in ancient Greek poetry.
Hesiod tells the story in Works and Days, a poem that combines moral instruction with practical advice about farming, justice, labor, and social conduct. In his account, Pandora’s opening of the jar releases troubles into a world that had previously been free from them. The episode functions as a mythic explanation for why human life includes hardship.
Hesiod is also credited with Theogony, which organizes the origins and relationships of the Greek gods. His works are among the earliest surviving Greek literary texts, and they strongly influenced later interpretations of Greek mythology.
Homer is a common wrong answer because the Iliad and Odyssey are the other major names associated with early Greek epic. However, the standard Pandora narrative comes from Hesiod, especially Works and Days, rather than from Homeric epic.
