In Hesiod’s Greek myth of Pandora, Prometheus’s brother Epimetheus became her husband. Epimetheus is described as Pandora’s companion after Zeus sent her to humanity, despite Prometheus warning him not to accept gifts from Zeus.
The names of the brothers help explain their contrasting roles. Prometheus is associated with foresight and is the protector who steals fire for humans. Epimetheus is associated with hindsight and accepts Pandora after she arrives. The myth therefore uses the brothers as a contrast between anticipating danger and recognizing it afterward.
Pandora’s arrival follows Prometheus’s theft of fire, so her marriage to Epimetheus forms part of the same chain of punishment. In the story, Pandora opens the container and releases troubles into the world; the surviving contents are treated separately in different interpretations.
Epimetheus is sometimes confused with Deucalion, who belongs to the later flood tradition and is associated with Pyrrha, Pandora’s daughter in later mythology. They are different figures.
