The phrase, verbis felicissime audax, used of Horace as a lyric poet by Quintilian, expresses, with something less than that fine critic's usual accuracy, another quality which goes far to make the merit of the Odes. Horace's use of words is, indeed, remarkably dexterous; but less so from happy daring than from the tact which perpetually poises and balances words, and counts no pains lost to find the word that is exactly right. His audacities—if one cares to call them so—in the use of epithet, in Greek constructions (which he uses rather more freely than any other Latin poet), and in allusive turns of phrase, are all carefully calculated and precisely measured. His unique power of compression is not that of the poet who suddenly flashes out in a golden phrase, but more akin to the art of the distiller who imprisons an essence, or the gem- engraver working by minute touches on a fragment of translucent stone. With very great resources of language at his disposal, he uses them with singular and scrupulous frugality; in his measured epithets, his curious fondness for a number of very simple and abstract words, and the studious simplicity of effect in his most elaborately designed lyrics, he reminds one of the method of Greek has-reliefs, or, still more (after allowing for all the difference made by religious feeling), of the sculptured work of Mino of Fiesole, with its pale colours and carefully ordered outlines. Phrases of ordinary prose, which he uses freely, do not, as in Virgil's hands, turn into poetry by his mere use of them; they give rather than receive dignity in his verses, and only in a few rare instances, like the stately Motum ex Metello consule civicum, are they completely fused into the structure of the poem. So, too, his vivid and clearly-cut descriptions of nature in single lines and phrases stand out by themselves like golden tesserae in a mosaic, each distinct in a glittering atmosphere—qua tumidus rigat arva Nilus; opacam porticus excipiebat Arcton; nec prata canis albicant pruinis—a hundred phrases like these, all exquisitely turned, and all with the same effect of detachment, which makes them akin to sculpture, rather than painting or music. Virgil, as we learn from an interesting fragment of biography, wrote his first drafts swiftly and copiously, and wrought them down by long labour into their final structure; with Horace we may rather imagine that words came to the surface slowly and one by one, and that the Odes grew like the deposit, cell by cell, of the honeycomb to which, in a later poem, he compares his own work. In some passages where the Odes flag, it seems as though material had failed him before the poem was finished, and he had filled in the gaps, not as he wished, but as he could, yet always with the same deliberate gravity of workmanship.
Horatii curiosa felicitas—this, one of the earliest criticisms made on the Odes, remains the phrase which most completely describes their value. Such minute elaboration, on so narrow a range of subject, and within such confined limits of thought and feeling, could only be redeemed from dulness by the perpetual felicity—something between luck and skill—that was Horace's secret. How far it was happy chance, how far deliberately aimed at and attained, is a question which brings us before one of the insoluble problems of art; we may remind ourselves that, in the words of the Greek dramatist Agathon, which Aristotle was so fond of quoting, skill and chance in all art cling close to one another. "Safe in his golden mediocrity," to use the words of his own counsel to Licinius, Horace has somehow or another taken deep hold of the mind, and even the imagination, of mankind. This very mediocrity, so fine, so chastened, so certain, is in truth as inimitable as any other great artistic quality; we must fall back on the word genius, and remember that genius does not confine itself within the borders of any theory, but works its own will.
With the publication of the three books of the Odes, and the first book of the Epistles, Horace's finest and maturest work was complete. In the twelve years of his life which were still to run he published but little, nor is there any reason to suppose that he wrote more than he published. In 17 B.C., he composed, by special command, an ode to be sung at the celebration of the Secular Games. The task was one in which he was much hampered by a stringent religious convention, and the result is interesting, but not very happy. We may admire the skill with which formularies of the national worship are moulded into the sapphic stanza, and prescribed language, hardly, if at all, removed from prose, is made to run in stately, though stiff and monotonous, verse; but our admiration is of the ingenuity, not of the poetry. The Jubilee Ode written by Lord Tennyson is curiously like the Carmen Seculare in its metrical ingenuities, and in the way in which the unmistakeable personal note of style sounds through its heavy and formal movement.
Four years later a fourth book of Odes was published, the greater part of which consists of poems less distinctly official than the Secular Hymn, but written with reference to public affairs by the direct command of the Emperor, some in celebration of the victories of Drusus and Tiberius on the north-eastern frontier, and others in more general praise of the peace and external prosperity established throughout Italy under the new government. Together with these official pieces he included some others: an early sketch for the Carmen Seculare, a curious fragment of literary criticism in the form of an ode addressed to one of the young aristocrats who followed the fashion of the Augustan age in studying and writing poetry, and eight pieces of the same kind as his earlier odes, written at various times within the ten years which had now passed since the publication of the first three books. An introductory poem, of graceful but half-ironical lamentation over the passing of youth, seems placed at the head of the little collection in studious depreciation of its importance. Had it not been for the necessity of publishing the official odes, it is probable enough that Horace would have left these few later lyrics ungathered. They show the same care and finish in workmanship as the rest, but there is a certain loss of brilliance; except one ode of mellow and refined beauty, the famous Diffugere nives, they hardly reach the old level. The creative impulse in Horace had never been very powerful or copious; with growing years he became less interested in the achievement of literary artifice, and turned more completely to his other great field, the criticism of life and literature. To the concluding years of his life belong the three delightful essays in verse which complete the list of his works. Two of these, which are placed together as a second book of Epistles, seem to have been published at about the same time as the fourth book of the Odes. The first, addressed to the Emperor, contains the most matured and complete expression of his views on Latin poetry, and is in great measure a vindication of the poetry of his own age against the school which, partly from literary and partly from political motives, persisted in giving a preference to that of the earlier Republic. In the second, inscribed to one of his younger friends belonging to the circle of Tiberius, he reviews his own life as one who was now done with literature and literary fame, and was giving himself up to the pursuit of wisdom. The melancholy of temperament and advancing age is subtly interwoven in his final words with the urbane humour and strong sense that had been his companions through life:—
Lusisti satis, edisti satis atque bibisti, Tempus abire tibi est, ne potum largius acquo Rideat et pulset lasciva decentius aetas.
A new generation, clever, audacious, and corrupt, had silently been growing up under the Empire. Ovid was thirty, and had published his Amores. The death of Virgil had left the field of serious poetry to little men. The younger race had learned only too well the lesson of minute care and formal polish so elaborately taught them by the earlier Augustan poets, and had caught the ear of the town with work of superficial but, for the time, captivating brilliance. Gloom was already beginning to gather round the Imperial household; the influence of Maecenas, the great support of letters for the last twenty years, was fast on the wane. In the words just quoted, with their half-sad and half- mocking echo of the famous passage of Lucretius,[8] Horace bids farewell to poetry.
But literary criticism, in which he had so fine a taste, and on which he was a recognised authority, continued to interest him; and the more seriously minded of the younger poets turned to him for advice, which he was always willing to give. The Epistle to the Pisos, known more generally under the name of the Art of Poetry, seems to have been composed at intervals during these later years, and was, perhaps, not published till after his death in the year 8 B.C. It is a discussion of dramatic poetry, largely based on Greek textbooks, but full of Horace's own experience and of his own good sense. Young aspirants to poetical fame regularly began with tragedies; and Horace, accepting this as an actual fact, discusses the rules of tragedy with as much gravity as if he were dealing with some really living and national form of poetry. This discursive and fragmentary essay was taken in later ages as an authoritative treatise; and the views expressed by Horace on a form of poetical art with which he had little practical acquaintance had, at the revival of literature, and even down to last century, an immense influence over the structure and development of the drama. Just as modern comedy based itself on imitation of Plautus and Terence, and as the earliest attempts at tragedy followed haltingly in the steps of Seneca, so as regards the theory of both, Horace, and not the Greeks, was the guiding influence.
Among the many amazing achievements of the Greek genius in the field of human thought were a lyrical poetry of unexampled beauty, a refined critical faculty, and, later than the great thinkers and outside of the strict schools, a temperate philosophy of life such as we see afterwards in the beautiful personality of Plutarch. In all these three Horace interpreted Greece to the world, while adding that peculiarly Roman urbanity—the spirit at once of the grown man as distinguished from children, of the man of the world, and of the gentleman—which up till now has been a dominant ideal over the thought and life of Europe.
