In Hesiod’s story, Prometheus warned Epimetheus not to accept gifts from Zeus.
Prometheus is portrayed as a benefactor of humanity and as a figure associated with foresight. After his conflict with Zeus, he cautions his brother Epimetheus against accepting anything sent by the Olympian ruler. Epimetheus ignores the warning when Pandora arrives.
The contrast between the brothers is reinforced by their names. Prometheus is commonly interpreted as “forethought,” while Epimetheus suggests “afterthought.” That wordplay helps explain why the warning is remembered as a central part of the myth.
Prometheus is often incorrectly named as Pandora’s husband. In Hesiod’s narrative, he is her brother-in-law: Pandora marries Epimetheus. The warning also belongs to the myth’s larger cycle involving fire, sacrifice, divine authority, and the consequences of resisting Zeus.
