One day Zeus sent a bull to Queen Pasiphae. She then slept with the bull and became pregnant. She became pregnant with a minotaur.
king Minos did not want to kill the minotaur so he sent it to the labyrinth, a maze type building. King Minos's son was in the Panathenaic games and was killed by the bull that impregnated his mom. Because of that king Minos would have king Ageous send seven people every year to kill the minotaur.
On the third year, king Ageous's son went to go kill the minotaur. Theseus, King Ageous's son, fell in love with King Minos's daughter, Ariadne, and she told him to use string to show his way out of the labyrinth. Then Theseus went into the Labyrinth.
Theseus went into the Labyrinth and fought the minotaur. After the battle, Theseus ended up winning and killed the Minotaur. Theseus used Ariadne's string that he unraved on his way to the minotaur to lead him.
Theseus and everyone else there had a celebration, but Ariadne fell asleep at the shore and after the celebration, they left without her. Before Theseus left he told his father he would put white sails up if he lived and black sails up if he died. Theseus was so overwhelmed that he forgot to change the sails, so the sails stayed black.
Theseus's father was watching on a rock to see what color the sails were. He saw the sails were black so he jumped into the ocean and committed suicide. That is why the ocean he jumped into is called the Ageous sea.
