Raised metal rim of the Greek shield (Hom. Il. 6,118; 15,645; 18,479 and passim); also refers to a hoop-like railing or ledge of the Greek racing and war chariot (archaic vase paintings [1.524 fig. 44]), which could be used to hold on to when stepping in or out (Hom. Il. 5,728 f.; 16,406). Evidently made of wood (Hom. Il. 21,38). When the chariot was not in motion, one could wrap the reins around the antyx (Hom. Il. 5,262).
