The single cause for complaint that Fronto had against his pupil was that, as he advanced in life, he gradually withdrew from the study of literature to that of philosophy. To Fronto, literature was the one really important thing in the world; and in his perpetual recurrence to this theme, he finds occasion to lay down in much detail his own literary theories and his canons of style. The _Elocutio Novella_, which he considered it his great work in life to expound and to practise, was partly a return upon the style of the older Latin authors, partly a new growth based, as theirs had been, on the actual language of common life. The prose of Cato and the Gracchi had been, in vocabulary and structure, the living spoken language of the streets and farms, wrought into shape in the hands of men of powerful genius. To give fresh vitality to Latin, Fronto saw, and saw rightly, that the same process of literary genius working on living material must once more take place. His mistake was in fancying it possible to go back again to the second century before Christ, and make a fresh start from that point as though nothing had happened in the meantime. In our own age we have seen a somewhat similar fallacy committed by writers who, in their admiration of the richness and flexibility of Elizabethan English, have tried to write with the same copiousness of vocabulary and the same freedom of structure as the Elizabethans. Between these and their object lies an insuperable barrier, the formed and finished prose of the eighteenth and nineteenth centuries; between Fronto and his lay the whole mass of what, in the sustained and secure judgment of mankind, is the classical prose of the Latin language, from Cicero to Tacitus. In the simplicity which he pursued there was something ineradicably artificial, and even unnatural, and the fresh resources from which he attempted to enrich the literary language and to form his new Latin resembled, to use his own striking simile, the exhausted and unwilling population from which the legions could only now be recruited by the most drastic conscription. Yet if Fronto hardly succeeded in founding a new Latin, he was a powerful influence in the final collapse and disappearance of the old. His reversion to the style and language of pre-Ciceronian times was only a temporary fashion; but in the general decay of taste and learning it was sufficient to break the continuity of Latin literature. The bronze age of Ennius and Cato had been succeeded, in a broad and stately development, by the Golden and Silver periods. Under this fresh attack the Latin of the Silver Age breaks up and goes to pieces, and the failure of Fronto and his contemporaries to create a new language opens the age of the base metals. The collapse of the imperial system after the death of Marcus Aurelius is not more striking or more complete than the collapse of literature after that of his tutor.
