When Zeus decided to end the Bronze Age with the great deluge, Deucalion and his wife, Pyrrha, were the only survivors. Even though he was imprisoned, Prometheus who could see the future and had foreseen the coming of this flood told his son, Deucalion, to build an ark and, thus, they survived. During the flood, they landed on Mount Parnassus, the only place spared by the flood.
