Pegasus

A winged horse.  When Perseus cut off the head of Medusa, Pegasus and Chrysaor sprang out.  Medusa had been pregnant with the two from her union with Poseidon, which was the reason she had become a gorgon in the first place.

The hero Bellepheron carried out his heroic tasks on the back of Pegasus.
