In Hesiod’s account, Prometheus warned his brother Epimetheus not to accept gifts from Zeus.
Prometheus understood that Zeus’s gift was dangerous because Zeus intended Pandora to bring consequences to humanity. He advised Epimetheus to reject gifts from the Olympian ruler. Epimetheus, whose name is often interpreted as “afterthought,” ignored the warning and accepted Pandora into his household.
This family relationship is central to the myth’s structure. Prometheus is the forward-thinking figure who anticipates danger, while Epimetheus acts only after events unfold. Pandora’s opening of the vessel then becomes connected to both divine punishment and human error.
Prometheus had already angered Zeus by stealing fire and giving it to mortals. In broader Greek mythology, Zeus punishes him by chaining him to a mountain while an eagle repeatedly eats his liver. Pandora’s story is another consequence of the conflict between Zeus and Prometheus.
