In Greek mythology, Pandora’s husband was called Epimetheus before the jar was opened.
Epimetheus is a Titan and the brother of Prometheus. His name is commonly understood as referring to “afterthought,” contrasting with Prometheus and his association with forethought. That contrast becomes a central piece of the story: Prometheus warns him not to accept a gift from Zeus, but Epimetheus takes Pandora into his home.
Pandora’s opening of the jar follows her arrival, and the released troubles become part of the myth’s explanation for human suffering. Epimetheus is therefore not merely a background character; his decision makes the story’s central event possible despite his brother’s warning.
Some retellings omit Epimetheus entirely and focus only on Pandora and the container. That simplification can make readers assume Prometheus was her partner. In the ancient account, however, the brothers have distinct roles: Prometheus is the fire-bringer and adviser, while Epimetheus is Pandora’s husband.
