Centaurs - half man half horse.
Centaur
A centaur is a mythological creature with the body, arms, and head of a man, but the front legs, back legs, and body of a horse.
Centaurs are part man, part horse. Chiron had the legs/body of a horse, but the torso, head, and arms of a man. Therefore, he was a centaur.
They are centaurs.
The cast of The Fastest Man on No Legs - 2009 includes: Oscar Pistorius
Half man, half horse specifically the torso, head and arms of a man, attached where the neck of a horse would have been, and the four legs, body and tail of a horse.
With someone on their back, it means: Two front legs up - man died in battle. One leg up - Man died from wounds caused in battle. All legs down: Man died from natural causes. :)

Centaur is a mythical creature with head, arms and torso of a man and body and legs of a horse. In Latin it is called Tatem.
It is called a centaur. If the upper half is human with the lower half horse and the horse section has all four horse legs, it is indeed a centaur. If it has the upper half of a human with the lower half of a horse but only 2 legs like a satyr it is a Sileni. There are also horse-headed men but I can not find the names for them. There is also the deity Hayagriva in Hinduism and Buddhism that has a white horse's head and a human body and is pictured as seated on a lotus.
