Pegasus was the mount of the hero Bellerophon. Together they destroyed the Chimera. Later Bellerophon, thinking that he was as great as the gods, rode up to Olympus. Zeus sent a gadfly to sting Pegasus who fell back to earth. Bellerophon landed in a thorn bush which left him blind and crippled for the rest of his life, which he spent as a hermit, whilst Zeus used Pegasus as a pack animal to carry his thunderbolts.
