In Greek mythology, Epimetheus was the son of Iapetus and brother of Prometheus and Atlas; "Epimetheus" is Greek for "hindsight."

He was responsible for giving a positive trait to every animal, but when it was time to give man a positive trait, there was nothing left. His brother Prometheus then stole fire from Zeus and gave it to man. As punishment, Zeus created Pandora for Epimetheus, knowing that he would fall in love with her despite the warnings of his more intelligent brother, who told him never to accept a gift from the Olympian gods ("Prometheus" means "foresight").

Epimetheus and Pandora were married. Pandora had been given a box by Hermes and was instructed never to open it. However, Hermes also gave her curiosity, and she opened it anyway releasing all the misfortunes of mankind. She shut it in time to keep one thing in the box: foreboding. Thus mankind always has hope in times of evil.

The daughter of Epimetheus and Pandora was Pyrrha, who married Deucalion and was one of the two who survived the deluge.
