How did the Greeks believe that the Aegean sea got its name?

The Greeks believed the Aegean Sea was named after King Aegeus of Athens. According to mythology, Aegeus, anxious about the fate of his son Theseus, who was fighting the Minotaur in Crete, mistakenly thought Theseus had died when he saw the ship's black sails returning. Heartbroken, Aegeus threw himself into the sea, which then took his name, becoming the Aegean Sea.
