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.
Today the vast majority of horse racing saddles are synthetic. The average training saddle may have a half tree or full tree.
