Ariadne

Ariadne, in Greek mythology, was the daughter of Minos, king of Crete, and Pasiphae. She gave to Theseus a clue and a ball of thread as help by which to escape out of the Minotaur's labyrinth. He unraveled the ball of thread given to him as he went in and used to trace his way out again after killing the Minotaur. Theseus had promised Ariadne to marry her after he had slain the Minotaur. He, therefore, took her with him to Naxos and left her there, where, according to one tradition, Artemis killed her, and according to another, Dionysos found her and married her, placing her at her death among the gods, and hanging her wedding wreath as a constellation in the sky.
