Centaurs

A centaur was a creature from Greek mythology, half man half horse. The head, arms and torso were human and were attached at the waist to the body and legs of a horse. These creatures represented barbarism and unbridled chaos, and were often depicted in Greek architectural sculpture and ceramic decoration. However, despite their bestial and lecherous reputation, not all centaurs received this unflattering portrayal, unless they had been drinking. So it may be that they were a warning metaphor for the dangers we face if we forget civility and lose control of our faculties.
