Pegasus (PEG-uh-sus). Winged horse, born from the blood of the Gorgon Medusa when she was decapitated by Perseus. Pegasus was fond of drinking from the spring of Peirene at Corinth. It was here that the hero Bellerophon, in need of a mount on which to attack the Chimaera, found the steed and tamed it with a golden bridle given him by Athena.
