The political reputation of Servius rests upon his organization of society according to a fixed scale of rank and fortune. He originated the census, a measure of the highest utility to a state destined, as Rome was, to future preeminence; for by means of its public service, in peace as well as in war, could thence forward be regularly organized on the basis of property; every man's contribution could be in proportion to his means.
