Pegasus 
 
Winged horse of Bellerophon. Pegasus was the offspring of Poseidon and the Gorgon Medusa. The winged steed was born, when the blood fell into sea from Medusa's neck. Pegasus was born at the same time as Chrysaor.

Bellerophon was only able to tame the steed when Athena gave the hero a golden bridle. Bellerophon used Pegasus in all his adventure: killing the monster Chimaera, defeating the Solymi and Amazons.

When Bellerophon thought to fly Pegasus to Olympus, the home of the gods, they send a gadfly to sting Pegasus. Bellerophon was thrown off his horse; the hero became lame for his misdeed. After this, Pegasus lived in the stable in Olympus offering his service to Zeus, carrying his thunderbolts.
