Centaurs are half-human, half-horse creatures in Greek mythology. They have the body of a horse and the torso, head and arms of a man. They were considered to be the children of Ixion, king of the Lapiths, and Nephele, a cloud made in the image of Hera.
Originally bred to run quarter mile races, the breed became known as the Quarter Horse. There is a possibility that an Arabian and quarter horse have been bred together to make a half bred quarter horse and a half bred Arabian. This is known in the horse industry as a Quarab and is considered a sport horse.
