The Titan whose name means “afterthought” and reflects his role in Pandora’s myth is Epimetheus.
Epimetheus is the brother of Prometheus and the husband of Pandora in Hesiod’s tradition. His name is commonly explained through Greek elements meaning “after” and “thought,” contrasting with Prometheus, whose name is associated with forethought.
That contrast shapes the story. Prometheus warns Epimetheus not to accept a gift from Zeus, but Epimetheus accepts Pandora anyway. The name thus functions as a characterization: Epimetheus acts first and understands the consequences later.
Epimetheus is less prominent than Prometheus in later popular culture, but he has an important structural role in the Pandora narrative. The myth uses the brothers as opposites, making their names part of its moral and literary design rather than merely labels for two unrelated Titans.
