ONE:After the revolution which destroyed the political power of the old aristocracy, there came a further revolution the effect of which was to diminish largely its social predominance. We learn from the bitter sarcasms of Horace and Juvenal that under the empire wealth took the place of birth, if not, as those satirists pretend, of merit, as a passport to distinction and respect. Merely to possess a certain amount of money procured admission to the equestrian and senatorial orders; while a smaller pecuniary qualification entitled any Roman citizen to rank among the Honestiores as opposed to the Humiliores, the latter only being liable, if found guilty of certain offences, to the more atrocious forms of capital punishment, such as death by the wild beasts or by fire.314 Even a reputation for learning was supposed to be a marketable commodity; and when supreme power was held by a philoso207pher, the vulgar rich could still hope to attract his favourable notice by filling their houses with books.315 We also know from Juvenal, what indeed the analogy of modern times would readily suggest, that large fortunes were often rapidly made, and made by the cultivation of very sordid arts. Thus members of the most ignorant and superstitious classes were constantly rising to positions where they could set the tone of public opinion, or at least help to determine its direction.
