Zeus's version of the Theseus myth is totally fabricated! Theseus went into the labyrinth all right, but the only thing he did in there was get lost. He never killed the Minotaur. Zeus made the whole thing up so everyone would think the Minotaur was gone for good. Hades, King of the Underworld, sets the record straight on the story of Theseus and the Minotaur.
