Deucalion, son of Prometheus, who, with his wife Pyrrha, by means of an ark which he built, was saved from a flood which for nine days overwhelmed the land of Hellas. On the subsidence of the flood they consulted the oracle at Delphi as to re-peopling the land with inhabitants, when they were told by Themis, the Pythia at the time, to throw the bones of their mother over their heads behind them. For a time the meaning of the oracle was a puzzle, but the readier wit of the wife found it out; upon which they took stones and threw them over their heads, when the stones he threw were changed into men and those she threw were changed into women.
