Pegasus, in Greek mythology, winged horse that carries the thunderbolt of Zeus. He sprang full-grown from the neck of the dying Gorgon Medusa. With a slash of his hoof, he created the Hippocrene, a sacred spring of the Muses on Mt. Helicon. Hence, he has often been associated with the arts, especially poetry. Pegasus was captured by Bellerophon , who rode him through many adventures. His name indicates a pre-Greek origin.
