ARMS, ARMA, in a general sense, includes all kinds of weapons, whether for defence or offence. Arms of stone and of brass appear to have been used before those of iron and steel. Josephus assures us that the patriarch Joseph first taught the use of iron arms in Egypt, arming the troops of Pharaoh with a casque and buckler. What contributed most to render the Romans masters of the world was, that having successively warred against all nations, they constantly renounced their own methods, arms, &c. wherever they met with better. Thus Romulus, during his war with the Sabines, a bold and warlike nation, adopted their broad buckler, in lieu of the small Argian buckler, which he had used till that time.
