Pegasus Rainbow

A winged horse in Greek mythology, Pegasus was supposedly the offspring of the sea god Poseidon and the Gorgon Medusa. According to legend, Pegasus was born from the blood that spurted from Medusa's neck when the hero Perseus killed her. Pegasus served Perseus until his death and afterward went to the home of the Muses. The water that gave the Muses their inspiration had dried up, so Pegasus stamped his hoof and created a spring.
