The Legend of the Cretian Minotaur

The King of Athens killed the son of Minos, King of Crete. In revenge, Minos conquered Athens and forced its King to send him seven youth and seven maidens every year as a tribute. These victims were then sent into a huge maze, or labyrinth on an island where they were devoured by a monster, half bull and half human, known as the Minotaur. A year came, and Theseus, son of the Athenian King bravely offered to form part of the doomed company. When he arrived in Crete, the daughter of Minos fell in love with him and gave him a sword and a piece of thread before he entered the maze. With the sword Theseus killed the Minotaur and with the thread he found his way back. The company was saved and the brave prince set sail to Greece.
Now Theseus had told his father, whose name was Aegeus that if he killed the Minotaur and found his way back he would hoist white sails as he came into port. But Theseus was so eager to arrive home that he forgot to do so. When Aegeus saw the black sails of the returning ships he thought his son was dead. In his grief the old King threw himself into the sea, which has ever since been called the Aegean Sea in memory of him.
