Who was Pandora’s brother-in-law in the Greek myth of the jar?

Prometheus was Pandora’s brother-in-law in the Greek myth of the jar.

Prometheus and Epimetheus were brothers, and Pandora married Epimetheus. Prometheus is the Titan most closely associated with humanity’s acquisition of fire. In Hesiod’s mythology, he deceives Zeus during a sacrifice and later steals fire for humans, provoking Zeus to impose further punishment.

Pandora’s creation is presented as part of that punishment. Zeus sends her to Epimetheus despite Prometheus’s warning that gifts from Zeus should be rejected. This makes Prometheus’s role central to the myth even though he is not the person who opens the jar.

Modern summaries sometimes blend several Prometheus traditions together. Greek sources differ in emphasis, and later writers add details such as Prometheus’s long-term punishment on Mount Caucasus. The stable connection in the Pandora story is that Prometheus’s theft of fire precedes the creation and delivery of Pandora as a divine response.
