King of Minos

The King of Minos imprisoned the Minotaur in a labyrinth and sacrificed seven young men and seven young maidens to it each year until Hercules was sent to capture the creature as one of his Labours. (PROSE: Mythical Monsters)

Behind the scenes
In the real world, the keeper of the Minotaur was King Minos, King of Crete, rather than a nameless King "of Minos" as claimed in Mythical Monsters. A mythological figure named Minos, not identified as King or linked explicitly to the Minotaur, was mentioned in Deadly Reunion.
