In the story of Pandora's box, Pandora married or joined Epimetheus.
Epimetheus was a Titan and the brother of Prometheus. His name is commonly interpreted as “afterthought,” contrasting with Prometheus, whose name is associated with foresight. In Hesiod's account, Prometheus warned Epimetheus not to accept a gift from Zeus, but Epimetheus accepted Pandora when she arrived.
Pandora's arrival places her inside the family story surrounding Prometheus's fire theft. After she came to Epimetheus, she opened the vessel and released the forces that had previously been confined. The myth thereby explains the arrival of suffering through a relationship arranged by the gods.
Modern versions often describe Pandora as Epimetheus's wife, although translations and retellings vary in wording. The stable point is that Epimetheus received her despite the warning associated with his brother. He is not the same figure as Prometheus, a frequent mix-up caused by their similar names.
