In the Greek myth of Pandora's box, Epimetheus became Pandora's husband after receiving her from the gods.
Epimetheus was the Titan associated with hindsight and the brother of Prometheus, whose name is linked with foresight. Zeus sent Pandora to Epimetheus as part of the punishment imposed on humanity after Prometheus stole fire for mortals. Although Prometheus warned his brother not to accept gifts from Zeus, Epimetheus accepted Pandora.
Hesiod's Works and Days presents Pandora as entering Epimetheus's household, where she opened the large storage jar that released troubles into the world. The popular phrase “Pandora's box” is a later wording; the earliest Greek account describes a jar, not a box. Epimetheus is therefore distinct from Prometheus, who appears earlier in the story through his theft of fire and his warning about Zeus's gifts.
