In Hesiod’s Works and Days, which Titan’s son is Pandora’s husband?

In Hesiod’s Works and Days, Pandora’s husband is Epimetheus.

Epimetheus is a Titan associated with afterthought and hindsight. His name contrasts with that of his brother Prometheus, whose name is commonly understood as meaning forethought. Hesiod’s story says Prometheus warned Epimetheus not to accept a gift from Zeus, but Epimetheus accepted Pandora when she arrived among humans.

Pandora’s marriage to Epimetheus is part of the myth’s explanation for humanity’s troubles. Zeus sends her as a divinely fashioned woman after Prometheus’s conflict with him over fire and sacrifice. Epimetheus is sometimes confused with Prometheus because the brothers appear together in the same mythic sequence. They are separate figures: Prometheus is Pandora’s warning-giving brother, while Epimetheus receives her as his bride.
