Deucalion  (dū-kā´li-on ).—Son of Prometheus, king of Phthia, in Thessaly, and husband of Pyrrha. He and his wife were the only human survivors of a great deluge which Jupiter sent to destroy mankind. They were preserved during the nine days' flood in a ship which Deucalion built on the advice of his father. The ship finally rested on Mount Parnassus, in Phocis. On the direction of Themis, Deucalion and his wife threw “the bones of their mother,” i. e. the stones of the earth, behind them, those thrown by Deucalion becoming men, and those thrown by Pyrrha becoming women. In this way the earth was repeopled.
