(Ancient Greek: Πήγασος, Pégasos, Latin Pegasus) one of the best known mythological creatures in Greek mythology. He is a winged divine horse, usually depicted as white in colour. 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.
