In Greek mythology, Deucalion was Pandora’s son-in-law and the survivor of the great flood. He was the son of Prometheus and the husband of Pandora’s daughter, Pyrrha.
Greek flood traditions describe Zeus sending a catastrophic flood to destroy the Bronze Age or an earlier human generation. Deucalion and Pyrrha survive in a chest or boat, depending on the version, and later receive instructions from the goddess Themis about restoring humanity.
Their solution involves throwing stones behind them; the stones become people. Deucalion’s story resembles other ancient flood narratives, but its distinctive continuation explains the Greek mythological ancestry of later humans.
