Centaur- Greek myth: a mans torso on the body of a horse in place of the head. They were either of a warrior class or teachers. Their behavior was so erratic because they were stuck between the animalistic world and human society.
Unicorns are not found in Greek mythology, but rather in natural history, as the Greeks were convinced the animals truly existed and said that their country of origin was India. During the Middle Ages and the Renaissance, unicorn horns were considered to have magical and medicinal properties, and hunting unicorns involved virgin maidens luring the animals with their innocence.
