S. Shoemaker and E. M. Shoemaker at Palomar. Hippolyta was one of the greatest queens of the Amazons. She wore a beautiful golden girdle, a gift from her father Ares, the war-god, as a symbol of her Amazonian queenship. Heracles was sent by the Greeks to acquire the girdle, a battle took place, and beautiful Hippolyta died.
