But when the gods completed this deception of sheer doom, against which there is no remedy,
Father Zeus sent the famed monster-killer (Hermes) to Epimetheus,
the swift messenger of the gods, bringing the gift. Nor did Epimetheus
take notice how Prometheus had told him never to accept a gift
from Zeus the Olympian, but to send it
right back, lest an evil thing happen to mortals.
But [Epimetheus] accepted it, and only then did he take note in his mind that he had an evil thing on his hands.
~ Hesiod, Works and Days
