The Minotaur is human in shape but with the head of a bull. The god Poseidon sent a beautiful white bull to Minos, the king of Crete, to be sacrificed. When Minos refused to kill the animal, Poseidon forced his wife, Queen Pasiphae, to fall in love with the bull. And it was because of the union of those two, woman and bull, that Minotaur was born.
