The use of a series of contrasts.

Fundamental Device.— A SERIES OF CONTRASTS.
A. MODEL.
It is difficult to decide on the comparative merit of
him [Fox] and Mr. Pitt : the latter had not the vehe¬ment reasoning, or argumentative ridicule of Mr. Fox ;
but he had more splendor, more imagery, and much more method and discretion	
Mr. Fox had a captivating earnestness of tone and manner ; Mr. Pitt was more dignified than earnest : . . . . it was an observation of the reporters in the gal¬lery, that it required great exertion to follow Mr. Fox while he was speaking, none to remember what he had said ; that it was'easy and delightful to follow Mr. Pitt, not so easy to recollect what had delighted them.
—	CHARLES BUTLER, Reminiscences, Mr. Fox and Mr. Pitt.
A.	EXAMPLE FOR ANALYSIS. 
Cicero, after con¬trasting the splendid troops of the Roman state with the wretchedness of the followers of Catiline, the conspirator, goes on to compare the two causes for which he, as the representative of Rome, and Catiline, who is aiming at the overthrow of Rome, respectively stand. He says :
For on the one side is fighting modesty, on the other wantonness ; on the one chastity, on the other unclean¬ness; on the one honesty, on the other fraud ; on the one piety, on the other wickedness ; on the one firm¬ness, on the other madness ; on the one honor, on the other baseness ; on the one continence, on the other lust; in short, equity, temperance, fortitude, prudence, all the virtues, contend against iniquity, luxury, indo¬lence, rashness, all the vices.
—MARCUS TULLIUS CICERO,
Against Catiline, Oration II., Ch. XI.
