Pyrrha’s husband in the Greek flood story was Deucalion. He is the son of Prometheus in many ancient genealogies, while Pyrrha is the daughter of Epimetheus and Pandora. Their marriage links the flood story to the generation created around the Pandora myth.
When Zeus sends a great flood, Deucalion and Pyrrha survive in a chest or ark-like vessel. After the flood, they ask how humanity can be restored. An oracle tells them to throw the bones of their mother behind them. They understand “mother” as Earth and “bones” as stones.
The stones thrown by Deucalion become men, and those thrown by Pyrrha become women. This unusual creation episode is based on wordplay in Greek and provides a mythic explanation for the renewal of humankind.
Deucalion is not the man who accepts Pandora in Hesiod’s jar story. That man is his mythological predecessor Epimetheus, whose name is frequently confused with Deucalion’s because the stories overlap genealogically.
