Named after the daughter of Epimetheus and Pandora {see planets  (1810) and  (55), respectively}. She married Deucalion, a son of Prometheus {see planet  (1809)}. Deucalion and Pyrrha were the only survivors of the deluge which Zeus {see planet  (5731)} sent to destroy mankind. The couple replaced the loss of mankind by throwing stones behind their backs — those Deucalion threw became men, those Pyrrha threw became women. (Z 226) _ _.
