Metope from the temple E of Selinunt in Sicily - now in Palermo, Museo Nazionale Archeologico (middle of the fifth century B.C.) This relief slab shows on the left side Heracles wearing the lion cap. He attacks an Amazon by seizing her helmet with his left hand. This Amazon is defending herself with a battle axe. Apparently it represents the combat between Heracles and the Amazon queen Hippolyte.
