Theseus, the central figure of "Theseus and the Minotaur", volunteered to go to slay the Minotaur. He promised to his father, Aegeus, that he would put up a white sail on his journey back home if he was successful. Ariadne, Minos' daughter, fell in love with Theseus and helped him get out of the Labyrinth by giving him a ball of thread, allowing him to retrace his path. Theseus killed the Minotaur. Theseus took Ariadne with him but on the return trip abandoned her on the island of Naxos. He also failed to fly white sails on his return journey, thus causing his father to throw himself into the Aegean sea, which was since named after him.
