Which Greek god warns his brother Epimetheus not to accept Pandora?

Prometheus warns his brother Epimetheus not to accept Pandora in the Greek myth.

Prometheus is the Titan associated with stealing fire from the gods and giving it to humanity. Zeus responds by arranging Pandora’s creation and sending her to Epimetheus, whose name is commonly interpreted as “afterthought.” Prometheus’s warning reflects his foreknowledge: he understands that a gift from Zeus may conceal a punishment.

Epimetheus ignores the warning and accepts Pandora. The story then connects her arrival with the opening of the storage jar and the release of human troubles. This pairing of brothers is central to the myth’s structure: Prometheus represents foresight, while Epimetheus represents reflection after an event.

The warning is not included in every modern retelling with equal detail, and some versions focus only on Pandora’s opening of the vessel. Hesiod’s account gives the brothers’ relationship an important role in explaining why Zeus’s plan succeeds.
