Dupondius
Dupondius or DUPONDIUM, a coin of two asses, struck after the reduction of the weight of the as. [AS] It was in use under the empire, when it was the weight of half an ounce. (Varr. L. L. 5.169, 9.81; Cic. Quinct. 16, 53; Plin. Nat. 33.42; Gaius, 1.122; Schol. ad Pers. 2.59; Marquardt, Röm. Staatsverw. ii. pp. 8, 11.) As the Romans applied the uncial division of the as to the foot, dupondium also signified two feet (Col. 3.15.2).
