The Pegasus was the mount of the hero Bellephron. Together they destroyed the Chimera. This flying horse gave him great agility to dodge the many blows from the Chimera. Later Bellephron thought that he was as great as the gods and rode to heaven on the back of Pegasus.
Pegasus represented divine inspiration as well as god-like apotheosis. Anyone who rode him could become a great poet. Pegasus's crescent-moon-shaped hoof stamped the ground and dug the Hippocrene (Horse-Well), a spring of poetic inspiration on Mount Helicon, the home of the Muses. This was another kind of immortality: the rider of Pegasus could figuratively "fly through the air to reach the heavens." Art titled "Still Your Golden Boy" by DirtySunshine
