Pegasus is one of the best known mythological creatures in Greek mythology. He is a winged divine stallion usually depicted as pure white in color. He was sired by Poseidon, in his role as horse-god, and foaled by the Gorgon Medusa. He was the brother of Chrysaor, born at a single birthing when his mother was decapitated by Perseus. Greco-Roman poets write about his ascent to heaven after his birth and his obeisance to Zeus, king of the gods, who instructed him to bring lightning and thunder from Olympus.
The winged horse Pegasos bursts forth in birth, from the decapitated neck of the Gorgon Medusa. The hero Perseus wings away with her head tucked inside his kibisis sack.
