In the Pandora myth, Epimetheus became Pandora's husband.
Epimetheus was a Titan and the brother of Prometheus. Zeus sent Pandora to him after her creation, and Epimetheus accepted her despite Prometheus's advice that he should reject gifts from Zeus. His decision places Pandora's arrival within the myth's wider story of divine punishment for the theft of fire.
The brothers' names create a deliberate contrast in Greek tradition. Prometheus is associated with forethought, while Epimetheus is associated with thinking afterward. That contrast makes Epimetheus's acceptance of Pandora especially significant: he acts first and understands the danger later.
Epimetheus is less prominent in popular culture than Pandora, but he appears in several myths involving the early history of humanity. In some traditions, he and Pandora are also connected with Pyrrha, who later survives the flood with Deucalion. Those stories belong to a broader Greek mythology of human origins.
