This theory has misled and impeded my predecessors in different ways: some, considering that the writers bewail the unavoidable dissolution of Roman society at the very time when Rome was most powerful, most cultured, richest, have judged conventional, rhetorical, literary, these invectives against corruption, these praises of ancient simplicity, and therefore have held them of no value in the history of Rome. Such critics have not reflected that this conception is found, not only in the literature, but also in the politics and the legislation; that Roman history is full, not only of invectives in prose and verse, but of laws and administrative provisions against _luxuria, ambitio, avaritia_--a sign that these laments were not merely a foolishness of writers, or, as we say to-day, stuff for newspaper articles. Other critics, instead, taking account of these laws and administrative provisions, have accepted the ancient theory of Roman corruption without reckoning that they were describing as undone by an irreparable dissolution, a nation that not only had conquered, but was to govern for ages, an immense empire. In this conception of corruption there is a contradiction that conceals a great universal problem. Stimulated by this contradiction, and by the desire of solving it, to study more attentively the facts cited by the ancients as examples of corruption, I have looked about to see if in the contemporary world I could not find some things that resembled it, and so make myself understand it. The prospect seemed difficult, because modern men are persuaded that they are models of all the virtues. Who could think to find in them even traces of the famous Roman corruption? In the modern world to-day are the abominable orgies carried on for which the Rome of the Cæsars was notorious? Are there to-day Neros and Elagabaluses? He who studies the ancient sources, however, with but a little of the critical spirit, is easily convinced that we have made for ourselves out of the much-famed corruption and Roman luxury a notion highly romantic and exaggerated. We need not delude ourselves: Rome, even in the times of its greatest splendour, was poor in comparison with the modern world; even in the second century after Christ, when it stood as metropolis at the head of an immense empire, Rome was smaller, less wealthy, less imposing, than a great metropolis of Europe or of America. Some sumptuous public edifices, beautiful private houses--that is all the splendour of the metropolis of the empire. He who goes to the Palatine may to-day refigure for himself, from the so-called House of Livia, the house of a rich Roman family of the time of Augustus, and convince himself that a well-to-do middle-class family would hardly occupy such a house to-day.
