Troezen was one of the children of Pelops and Hippodamia. He was the father of Anaphlystus and Sphettus. Evopis was also credited to be his daughter. Troezen and his brother Pittheus were said to have gone to King Aetius, son of Anthas, who reigned over the cities of Hyperea and Anthea. They became his co-rulers, and then successors. When Troezen died, Pittheus incorporated the two cities into one and named it Troezen after him.
