Explanation:

Kinnaras, another half-man, half-horse mythical creature from Indian mythology, appeared in various ancient texts, arts, and sculptures from all around India. It is shown as a horse with the torso of a man where the horse's head would be, and is similar to a Greek centaur.

It comes from the ancient Greek word kentauros, which is sometimes considered to literally mean 'bull-killer.' According to the Greek mythology, there was a whole race of them, usually described as ferocious and with somewhat beastly and uncivilized appetites. Chiron was unique case: he was Cronus' son, wise and just, and had taught a lot of Greek heroes like Achilles and Jason.
