Pegasus (character)

Pegasus (Πήγασος in Greek) is a winged horse. He was born when Perseus cut off the head of the monster Medusa.

History
In myths, Pegasus is the immortal son of the sea god Poseidon and Medusa. After Medusa was slain by the hero Perseus, Pegasus sprang up from her decapitated neck stump. Eventually, with the aid of Athena, the hero Bellerophon captured him. With his aid, Bellerophon was able to slay the Chimera. In time, Bellerphon's pride drove him to attempt to fly to the top of Olympus. Zeus punished him for his arrogance by sending a gadfly to sting Pegasus and buck off Bellerophon, crippling him. Pegasus completed the trip to Mount Olympus and took its place in Zeus' stables. It was often viewed as carrying Zeus' thunderbolts. In some stories, Zeus eventually placed it among the stars.

In some myths it is mentioned that Pegasus was a son of Demeter and Poseidon. Poseidon tried to flirt with Demeter, but she turned herself into a horse and ran away. But then Poseidon also turned into a horse followed her and Pegasus was born.
