Pandora’s husband in the Greek myth is Epimetheus. He is the brother of Prometheus and receives Pandora after the gods send her to humanity. His name is commonly interpreted as “afterthought,” contrasting with Prometheus, whose name is associated with forethought.
That contrast helps explain Epimetheus’s role in the story. Prometheus warns him not to accept gifts from Zeus, but Epimetheus accepts Pandora anyway. When the jar is later opened, the consequences affect the whole human race rather than only the couple. Pandora and Epimetheus therefore function as mythic ancestors within a story about how suffering entered human life.
Epimetheus is less prominent in Greek mythology than Zeus or Prometheus, and modern summaries sometimes identify Pandora only as a woman created by the gods without naming her husband. Hesiod’s Works and Days does name Epimetheus in the surrounding narrative.
The name is not a synonym for Prometheus. They are brothers with deliberately contrasting names and traits, and confusing them changes the structure of the myth.
