Centaur

Centaurs are a hybrid monster of half-man, half- horse from Greek mythology. They are depicted with a wild, untamed, "horse-like" nature, with excessive sexual appetites. However there are also moral and wise Centaurs as well, such as Chiron the teacher. The most prevalent theory on the origin of Centaurs is that it is a misinterpretation of a riding culture by a those who are unfamiliar with horses. A man mounted on a horse would appear as one animal at a distance.

Faun

Fauns are woodland spirits, associated with the Greek God Pan. They are generally depicted with a human head and torso, horns, and goat's legs, and may also be shown with a goat's head. The difference between Fauns and Saytrs is the latter are shown with human feet and legs.

Fauns are usually shown as mischievous as apposed to evil, with a very "randy" disposition. Much of the imagery depicting Fauns in Greek statuary and vasework show them reveling with drink and women (and men.) In late antiquity and the middle ages Fauns were used symbolically to represent those with an aggressive sex drive.
