What we know of the political conduct of Cleon comes from measurably unreliable sources. Aristoph'anes, the chief of the comic poets, describes him as "a noisy brawler, loud in his criminations, violent in his gestures, corrupt and venal in his principles, a persecutor of rank and merit, and a base flatterer and sycophant of the people." Thucydides also calls him "a dishonest politician, a wrongful accuser of others, and the most violent of all the citizens." Both these writers, however, had personal grievances. Of course Cleon very naturally became a target for the invective of the poet. "The taking of Pylus," says GILLIES, "and the triumphant return of Cleon, a notorious coward transformed by caprice and accident into a brave and successful commander, were topics well suiting the comic vein of Aristophanes; and in the comedy first represented in the seventh year of the war--The Knights--he attacks him in the moment of victory, when fortune had rendered him the idol of a licentious multitude, when no comedian was so daring as to play his character, and no painter so bold as to design his mask." The poet himself, therefore, appeared on the stage, "only disguising his face, the better to represent the part of Cleon." As another writer has said, "Of all the productions of Aristophanes, so replete with comic genius throughout, The Knights is the most consummate and irresistible; and it presents a portrait of Cleon drawn in colors broad and glaring, most impressive to the imagination, and hardly effaceable from the memory." The following extract from the play will show the license indulged in on the stage in democratic Athens, the boldness of the poet's attacks, and will serve, also, as a sample of his style: Cleon the Demagogue. The chorus come upon the stage; and thus commence their attack upon Cleon: Chorus. Close around him, and confound him, the confounder of us all; Pelt him, pummel him, and maul him; rummage, ransack, overhaul him; Overbear him and outbawl him; bear him down, and bring him under. Bellow, like a burst of thunder, robber! harpy! sink of plunder! Rogue and villain! rogue and cheat! rogue and villain, I repeat! Oftener than I can repeat it has the rogue and villain cheated. Close around him, left and right; spit upon him, spurn and smite: Spit upon him as you see; spurn and spit at him like me. But beware, or he'll evade you! for he knows the private track Where En'crates was seen escaping with his mill-dust on his back. Cleon. Worthy veterans of the jury, you that, either right or wrong, With my threepenny provision I've maintained and cherished long, Come to my aid! I'm here waylaid--assassinated and betrayed"!
