But let no innovation be established contrary to the precedents and principles of our ancestors.— I will not say, at this moment, that our ancestors in peace always obeyed usage, but in war were always guided by expediency, and always accommodated themselves with new plans to the new emergencies of the times. I will not say that two most important wars, the Punic war and the Spanish war, were put an end to by one general; that two most powerful cities, which threatened the greatest danger to this empire— Carthage and Numantia, were destroyed by the same Scipio. I will not remind you that it was but lately determined by you and by your ancestors, to rest all the hopes of the empire on Caius Marius, so that the same man conducted the war against Jugurtha, and against the Cimbri, and against the Teutones. But recollect, in the case of Cnaeus Pompeius himself, with reference to whom Catulus objects to having any new regulations introduced, how many new laws have been made with the most willing consent of Quintus Catulus.
