Minotaur : From Greek mythology, a man eating monster who was partly a bull and partly a man. It was conceived when Pasiphae mated with a bull. Each year, seven youths from Athens, including seven young men and seven young women, were fed to him as a form of ongoing tribute. Theseus, the Athenian hero, killed the Minotaur with assistance from King Minos's daughter the princess Ariadne.
