The son of Achilles and Deidamea. The name of Pyrrhus is said to have been given to him by Lycomedes, because he had fair (πυρρός) hair, or because Achilles, while disguised as a girl, had borne the name of Pyrrha.1
The phrase a Pyrrhic victory is named for Pyrrhus and means "a victory won at such great cost to the victor that it is tantamount to a defeat."
