Now, in criticising this criticism we must of course take into consideration the plea that Horace may not have meant to give [Sidenote: _Its desultoriness_] a regular treatise even on Dramatic Poetry, but merely to throw out a few observations for the benefit of a friend. It is still more obvious that we must not saddle him with all the rubbish of corollary and comment with which he has been loaded (sometimes without his having in the least deserved or provoked it) by the “Classical” critics of the 16th-18th centuries. Yet not merely equitable but generous allowances of this kind will still leave the piece open to pretty severe comment. In the first place, its desultoriness is excessive, even extravagant. Much licence in this respect no doubt must be allowed to the “mixer of the useful and the pleasant” by means of verse-didactics. But no possible licence will cover Horace’s method, or absence of method. He begins with a sufficiently lively diatribe against inconsistency of design and want of harmony of parts, then slides to methods of composition, thence to vocabulary, thence to the technical divisions of prosody, thence to stock characters and the selection of subject, gives cautions as to the minor and more arbitrary proprieties of the stage, indulges in a little bit of literary history, returns to metres, insists on the importance of self- and other criticism. Then he shifts artfully to the contrast between Greek emulation and Roman shopkeeping covetousness, extols Orpheus and Amphion, Homer and Tyrtæus, excuses faults if they are not too many, but will not tolerate mere even mediocrity, cautions against flattering hearers, and ends with a description, half sarcastic, half rallying the sarcasm, of bad poets. If it were not for its vividness and its constellation of glittering phrases, nobody could see in such a thing aught but a mere congeries of desultory observations.
