From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
He belonged to the circle of the highest nobility, and was the possessor of a colossal fortune; in disposition too he was a genuine aristocrat--a man emphatically proud, who scorned to bedeck himself with the insignia of his offices, but declared on his death-bed that there would not soon arise a citizen like to him; a man with whom the beautiful saying, that nobility implies obligation, was and continued to be the rule of his life. With all the vehement earnestness of his temperament he had turned away from the frivolity and venality that marked the nobles of the common stamp; trustworthy and strict in morals, he was respected rather than properly beloved on the part of the common people, to whom his door and his purse were always open, and notwithstanding his youth, he was through the personal dignity of his character a man of weight in the senate as in the Forum.
Nor did he stand alone. Marcus Scaurus had the courage on occasion of his defence in the trial for extortion publicly to summon Drusus to undertake a reform of the judicial arrangements; he and the famous orator, Lucius Crassus, were in the senate the most zealous champions of his proposals, and were perhaps associated with him in originating them. But the mass of the governing aristocracy was by no means of the same mind with Drusus, Scaurus, and Crassus.
