  Damaretus of Heraea , his son and his grandson, each won two victories at Olympia . Those of Damaretus were gained at the sixty-fifth Festival ¹ (at which the race in full armour was instituted) and also at the one succeeding. His statue shows him, not only carrying the shield that modern competitors have, but also wearing a helmet on his head and greaves on his legs. In course of time the helmet and greaves were taken from the armour of competitors by both the Eleans and the Greeks generally. Theopompus, son of Damaretus, won his victories in the pentathlum, and his son Theopompus the second, named after his father, won his in the wrestling-match.
