In Greek mythology, the Minotaur, also known as Asterion or Asterius, is a mythical creature portrayed during classical antiquity with the head and tail of a bull and the body of a man or, as described by Roman poet Ovid, a being "part man and part bull". He dwelt at the center of the Labyrinth, which was an elaborate maze-like construction designed by the architect Daedalus and his son Icarus, upon command of King Minos of Crete. According to tradition, every nine years the people of Athens were compelled by King Minos to choose fourteen young noble citizens to be offered as sacrificial victims to the Minotaur in retribution for the death of Minos's son Androgeos. The Minotaur was eventually slain by the Athenian hero Theseus, who managed to navigate the labyrinth with the help of a thread offered to him by the King's daughter, Ariadne.
