In Greek mythology, Epimetheus is described as Pandora’s husband in the tradition that connects them with Deucalion. Epimetheus is the brother of Prometheus, whose name is commonly interpreted as “afterthought,” contrasting with Prometheus, or “forethought.”
According to Hesiod, Prometheus warns Epimetheus not to accept gifts from Zeus. Epimetheus nevertheless accepts Pandora, who brings the sealed container whose opening releases troubles into the human world. The pairing reinforces the myth’s contrast between foresight and hindsight.
Later mythographic traditions connect Pandora and Epimetheus with a daughter named Pyrrha. Pyrrha marries Deucalion, and the pair survive a great flood before repopulating the world by casting stones behind them. This makes Pandora part of the broader ancestry story of later humanity.
Epimetheus is sometimes confused with Prometheus because the two are brothers and both belong to the same cycle of myths. The husband in the Pandora story is Epimetheus, not Prometheus or Deucalion.
