Answer: Pegasus, the Winged Horse
Explanation: Pegasus is one of the most popular creatures in Greek mythology. He is a mythical winged divine horse usually depicted as pure white. Pegasus is the offspring of the Olympian god Poseidon and was foaled by the Gorgon Medusa upon her death, when she was beheaded by Perseus.
According to Greek mythology, Pegasus had other special abilities apart from being able to fly which literally set him above all other horses. For one, he had free passage from the mortal realm to the immortal realm and could travel between both worlds at will. Also, it was said that wherever his hoof struck the Earth, he created beautiful springs with water which inspired artists.
