The Minotaur is the monstrous son of a white bull, sent by Poseidon and Pasiphae, the wife of the Crete king, Minos. The child was born with the body of a man and the head of a bull, and was named Minotaur (Minos' Bull).
The Minotaur fed each year on seven boys and seven girls, who were sent as a tribute by the Athenians. To stop these sacrifices, the hero Thesus entered the Labyrinth where the Minotaur lived and killed it. Thesus was aided by Minos' daughter, Ariadne, who gave him a sword to slay the beast, and a ball of thread which he could unravel through the maze so he could find his way out.
