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.
CENTAUR: In Greek mythology, this was the name of a type of creature part human and part horse. They were depicted as being wild, lawless and inhospitable, having truly animalistic passions. However, two centaurs, Pholus (of the cave or den) and Chiron (surgeon), are said to have been good-natured centaurs.
