In the Myth of Aegeas the mythical king of Athens we learn that his son Theseus, traveled to Crete
with the mission to kill the famous beast named Minautaurus. His father asked him a favor, if he made it and survived from the Labyrinth, he had to change, on his return, the black sails of his ship "Argo", since Theseus sailed to Crete with black ones. The sign that he had killed the Minautaurus would be the white sails he would have put in this return. Aegeas, according to the Myth, waited on a high cliff in Sounio, so to watch from far his sons return from Crete.
But Theseus who eventhough had killed the wild beast,had forgotten to change the sails. So his father saw the ship coming with black sails and believed that his son had been killed by the Minautaurus, in the Labyrinth. He could not bear the pain of his beloved son's death and he did not wait for the ship to reach the coast but he fell from the cliff in the sea and drowned himself. Since then, this sea is still called Aegean sea due to Aegea's suicide in these waters. An act that will always symbolize the endless love a father has for his son, which is biggest than the most immense sea.
