Kleon acquired his first importance among the speakers against Periklês, so that he would thus obtain for himself, during his early political career, the countenance of the numerous and aristocratical anti-Perikleans. He is described by Thucydidês in general terms as a person of the most violent temper and character in Athens,—as being dishonest in his calumnies, and virulent in his invective and accusation.[406] Aristophanês, in his comedy of the Knights, reproduces these features, with others new and distinct, as well as with exaggerated details, comic, satirical, and contemptuous. His comedy depicts Kleon in the point of view in which he would appear to the knights of Athens,—a leather-dresser, smelling of the tan-yard,—a low-born brawler, terrifying opponents by the violence of his criminations, the loudness of his voice, the impudence of his gestures,—moreover, as venal in his politics, threatening men with accusations, and then receiving money to withdraw them; a robber of the public treasury, persecuting merit as well as rank, and courting the favor of the assembly by the basest and most guilty cajolery. The general attributes set forth by Thucydidês (apart from Aristophanês, who does not profess to write history), we may well accept; the powerful and violent invective of Kleon, often dishonest, together with his self-confidence and audacity in the public assembly. Men of the middling class, like Kleon and Hyperbolus, who persevered in addressing the public assembly and trying to take a leading part in it, against persons of greater family pretension than themselves, were pretty sure to be men of more than usual audacity. Had they not possessed this quality, they would never have surmounted the opposition made to them: we may well believe that they had it to a displeasing excess,—and even if they had not, the same measure of self-assumption which in Alkibiadês would be tolerated from his rank and station, would in them pass for insupportable impudence. Unhappily, we have no specimens to enable us to appreciate the invective of Kleon. We cannot determine whether it was more virulent than that of Demosthenês and Æschinês, seventy years afterwards,—each of those eminent orators imputing to the other the grossest impudence, calumny, perjury, corruption, loud voice, and revolting audacity of manner, in language which Kleon can hardly have surpassed in intensity of vituperation, though he doubtless fell immeasurably short of it in classical finish. Nor can we even tell in what degree Kleon’s denunciations of the veteran Periklês were fiercer than those memorable invectives against the old age of Sir Robert Walpole, with which Lord Chatham’s political career opened. The talent for invective possessed by Kleon, employed first against Periklês, would be counted as great impudence by the partisans of that illustrious statesman, as well as by impartial and judicious citizens; but among
