Queen Pasiphae slept with a bull sent by Zeus, and gave birth to Minotaur, a creature half man – half bull. King Minos was embarrassed, but did not want to kill the Minotaur, so he hid the monster in the Labyrinth constructed by Daedalus at the Minoan Palace of Knossos. According to the myth, Minos was imprisoning his enemies in the Labyrinth so that the Minotaur could eat them. The labyrinth was such a complicated construction that no one could ever find the way out alive.The third year, Theseus, son of Aegeus decided to be one of the seven young men that would go to Crete, in order to kill the Minotaur and end the human sacrifices to the monster. King Aegeus tried to make him change his mind but Theseus was determined to slay the Minotaur.Theseus promised his father that he would put up white sails coming back from Crete, allowing him to know in advance that he was coming back alive. The boat would return with the black sails if Theseus was killed.Theseus announced to King Minos that he was going to kill the Monster, but Minos knew that even if he did manage to kill the Minotaur, Theseus would never be able to exit the Labyrinth.

Theseus met Princess Ariadne, daughter of King Minos, who fell madly in love with him and decided to help Theseus. She gave him a thread and told him to unravel it as he would penetrate deeper and deeper into the Labyrinth, so that he knows the way out when he kills the monster. Theseus followed her suggestion and entered the labyrinth with the thread. Theseus managed to kill the Minotaur and save the Athenians, and with Ariadne’s thread he managed to retrace his way out. Theseus took Princess Ariadne with him and left Crete sailing happily back to Athens. In a tragic turn of events, Theseus sailed back to Athens forgetting in his elation to replace the black sails with white ones as a signal of victory. His father Aegean who was watching for the returning ships from the Sounio rock saw the black sail, and in despair for what he thought was a failed mission that resulted to the death of his son, ended his life by jumping into the sea. The sea henceforth is named Aegean sea in his memory.
