In Hesiod’s account, Epimetheus accepted Pandora despite his brother’s warning.
Epimetheus was a Titan and the brother of Prometheus. Hesiod’s Works and Days says Prometheus warned Epimetheus not to accept any gift from Zeus. Epimetheus nevertheless received Pandora, who had been sent as part of Zeus’s punishment for Prometheus’s theft of fire.
The story uses the brothers’ names symbolically. Prometheus is associated with forethought, while Epimetheus is associated with thought after the event. That contrast makes Epimetheus’s decision an example of acting first and understanding the consequences later.
Later retellings often describe Pandora as Epimetheus’s wife, but the earliest surviving accounts focus more strongly on the gift and its consequences than on a detailed marriage narrative. Epimetheus should also not be confused with Prometheus, who is the fire-bringer and the character who issues the warning.
