A centaur, occasionally hippocentaur, also called Ixionidae, is a creature from Greek mythology with the upper body of a human and the lower body and legs of a horse that was said to live in the mountains of Thessaly. In one version of the myth, the centaurs were named after Centaurus, and, through his brother Lapithes, were kin to the legendary tribe of the Lapiths.
