Phlegyas

Phlegyas, son of Ares and Chryse, King of the Lapiths in Greek mythology was father of Ixion and Coronis, one of Apollo's lovers. Pregnant with Asclepius, Coronis fell in love with Ischys, son of Elatus. A crow informed Apollo of the affair and he sent his sister, Artemis, to kill Coronis. Apollo rescued the baby though and gave it to the centaur Chiron to raise. Phlegyas was irate and torched the Apollonian temple at Delphi and Apollo killed him.

Phlegyas was the mythical ancestor of the Phlegyans[?].
