Found in the Asklepieion at Epidauros. Asklepios is depicted at the left seated on an elaborate throne. His wife, Epione, stands next to him. In the middle, a youth wearing a chiton, chlamys, high shoes and a sword offers the god an object that resembles a model of a horse's head. He is probably Hippolytos, attended by a young groom.
