The Clew of Ariadne
Ariadne, daughter of King Minos of Crete, gave Theseus a ball of thread known as a "clew" so that he could find his way out of the labyrinth where he would otherwise have been devoured by the dreaded Minotaur. Theseus later abandoned Ariadne on the island of Naxos, where she remarried the god Bacchus and bore many children.
