Daedalus fled to the island of Crete, where he began to work at the court of King Minos and Queen Pasiphae, in the magnificent palace of Knossos. When the Minotaur was born, Daedalus built the Labyrinth to contain the monstrous half-man, half-bull. For years Minos demanded a tribute of youths from Athens to feed the creature. Eventually, the hero Theseus came to Crete to attempt to slay the Minotaur. Ariadne, daughter of Minos and Pasiphae, fell in love with Theseus and asked Daedalus to help him. Daedalus gave her a flaxen thread for Theseus to tie to the door of the Labyrinth as he entered, and by which he could find his way out after killing the monster. Theseus succeeded, and escaped Crete with Ariadne. Minos, enraged at the loss of his daughter, not to mention the killing of the Minotaur, shut Daedalus and his son Icarus into the Labyrinth.
