Theseus, king-founder of Athens.

Theseus volunteered to take the place of one of the youths and set off with a black sail, promising to his father, Aegeus, that if successful he would return with a white sail. Like the others, Theseus was stripped of his weapons when they sailed. On his arrival in Crete, Ariadne, King Minos’ daughter, fell in love with Theseus and, on the advice of Daedalus, gave him a ball of thread or clue, so he could find his way out of the Labyrinth.
