Satire was not only national in its intellectual and moral characteristics, but it played a part in public life at Rome. Even under the Empire, when free speech and comment on the government were no longer possible, the Roman satirists claimed to perform an office similar in spirit to that which the Republic in its best days had devolved on its most honourable magistracy. But the satire of the Republic, besides performing this magisterial office, played an active part in the politics of the day. It combined the freedom of a tribune with the severity of a censor. It held up to public criticism the delinquencies of leading politicians, and of the mass of the people in their elective divisions,-- Primores populi arripuit populumque tributim. Nor was it confined to aggressive criticism: it was used also as an instrument of political partisanship, to paint the virtues of Scipio as well as the vices of his antagonists. It thus performed something of the same kind of public office as the political pamphlet of an earlier time, and the newspaper of the present day. It endeavoured also, by acting on individual character, to effect objects which the Roman State strove to accomplish by direct legislation. The various sumptuary laws of that age, and the enactments made to repress the study of Greek rhetoric and philosophy, emanated from the same spirit which led Lucilius to denounce the increase of luxury and the affectation of Greek manners among his contemporaries. The strong Roman appetites and the novelty of new studies prevailed alike over the artificial restraints of legislative enactments, and over the contemptuous and the earnest teaching of satire. But the influence of satire could reach further than that of censors or sumptuary laws. While it could brand notorious offenders it was able also to unmask hypocritical pretences-- Detrahere et pellem, nitidus qua quisque per ora Cederet, introrsum turpis. It could stimulate to virtue as well as denounce flagrant offences. It wielded something of the power of the preacher to produce an inward change in the characters of men. By its close contact with real experience and its close adherence to the national standard of virtue, it might educate men for the duties of citizens more effectually than the teaching of Greek rhetoric or philosophy.
