make us regret that the conditions of his art, as conceived by him, did not encourage him to blend something more of idyllic representation with the didactic and descriptive treatment of his subject. But the idyl which treats the incidents of human life in the form either of a continuous poem or of a tale in prose was unknown to the early art of Greece; and Roman imagination was incapable of inventing a perfectly new mould into which to cast its poetic fancies and feelings. Nor is it probable that a poem so truly representative of Italy in all its aspects could have been produced in the form of an idyl, of which the interest would have been concentrated on some family or group of personages.
II.
There was only one form of literary art known to the Greeks or Romans of the Augustan Age which was at all suitable for the treatment on a large scale of such a subject as that which now filled the mind of Virgil. Next after the epic poem of heroic action, the didactic epos was regarded at Rome as the most serious and elaborate form of poetic art. It was more suited than any other form to the Roman mind. It is the only form in which the genius of Rome has produced master-pieces superior not only to anything of the kind produced by Greece but to all similar attempts in modern times. As Roman invention, stimulated by the practical sense of utility, by the passion for vast and massive undertakings, and by the strong perception of order and unity of design, devised a new kind of architecture for the ordinary wants of life, so in accordance with the national bent to reduce all things to rule, to impose the will of a master on obedient subjects, to use the constructive and artistic faculties for some practical end, if it did not create, it gave ampler compass, more solid and massive workmanship, and the associations of great ideas to that form of poetic art which had been the most meagre and unsubstantial of all those invented by the genius of Greece.
Moreover, a new form, or rather a form of more ample capacity, was required to embody the new poetical feelings and experience which now moved the Roman and Italian [pg 181]mind. If less interest was felt at Rome in following the course of individual destiny, the interest felt in contemplating the outward aspect and secret movement of Nature was now stronger than it had been in the great ages of Greek literature. Though the vivid enjoyment of the outward world had unconsciously shaped the tales of the early Greek mythology, and though this enjoyment had entered directly, as a subordinate element, into the epic, lyric, and dramatic poetry of Greece, and, more prominently, into the later poetry of Alexandria, and although the phenomena and laws of Nature had aroused the speculative curiosity of the early Greek philosophers, no poet before Lucretius had treated of Nature, in the immensity of her range, in the primal elements and living forces of her constitution, and, at the same time, in her manifold aspects of beneficence and beauty, and of destructive energy, as the subject of a great poem. The forms adopted by the great masters of Greek poetry,—the epic, lyric, and dramatic writers,—whose essential business it was to represent the actions and passions of men, were inapplicable to the treatment of this new subject of man’s environment. Lucretius accordingly had to take the outline of his form from the early physiological writers, whom the Greeks scarcely ranked among their poets at all, and who, though animated by the speculative passion to penetrate to the secret of Nature, were not specially interested in her aspects of beauty or power, or in her relation to the life of man. If he cannot claim the title of an inventor in art, yet by adding volume and majesty to the rudimentary type of these early writers, he gave to the ancient world the unique specimen of a great philosophical poem.
So too Virgil, penetrated with the feeling of Nature in her relation to human wants and enjoyment, and desirous to give an adequate expression to this feeling, could derive no guidance from the nobler genius of Greece. To find a suitable vehicle, he had to turn to the earliest and latest periods of her literature. The didactic, as distinct from the philosophic or contemplative poem, was the invention of a time prior to the existence of [pg 182]prose composition. It seems to have arisen out of the impulse to convey instruction and advice on the management of life generally, and especially on the best means of securing a livelihood from the cultivation of the soil. The use of the language of poetry for a purpose essentially practical and prosaic was justified, in that primitive time, not only by the absence of any other organ of literary expression, but also by the fact that, in such a time, all literary effort was the result of animated feeling, and that the most common aspects of Nature, such as the changes of the seasons or of night and day, and what seem now the most familiar occupations of life, were apprehended by the lively mind of the Greek with a fresh sense of wonder, which use deadens in eras of more advanced civilisation. But while this sense of wonder imparts a poetical colouring to the language of early didactic poetry, and while sufficient harmony was secured for it by the training of the ear during centuries of epic song, the form and structure of this kind of art was, as compared with the other forms of Greek poetry, essentially rudimentary. The sole specimen which has reached our times appears in the form of a personal address, treating of a number of subjects not closely connected with one another, interspersed with various episodes, and producing the impression of a connected whole solely through the vivid personality of the writer. Didactic poetry was absolutely rejected in the maturity of Greek genius, after the rise of a prose literature had marked off clearly the separate provinces of prose and poetry, and after Greek taste had become more exacting in its demand of unity of impression and symmetry of form in every work of art. It was revived again in the Alexandrian epoch, when the creative impulse was lost, and life and its interests had become tamer, while at the same time knowledge had greatly increased, and a kind of literary dilettanteism was one of the chief elements in refined enjoyment. By the Alexandrine writers the irregular and desultory treatment of Hesiod was abandoned. The didactic poem was treated by them as one of the recognised branches of poetical art. It still retained the general character [pg 183]of a personal address, which accident may have first suggested to Hesiod, and which either his example or their own taste had imposed on the early philosophic poets. The Alexandrine type of poem differed from that of Hesiod by professing to convey systematic instruction on some definite branch of knowledge, instead of offering practical directions on the best method of carrying on some occupation, combined with a medley of precepts, moral, religious, and ceremonial. The change may be compared to that which the Roman satire underwent, from the inartistic medley of Ennius and Lucilius to the systematic treatment of some special subject in the satire of Persius and Juvenal. The primary aim of such writers as Aratus and Nicander was not to communicate ideas capable of affecting the imagination, but to satisfy intellectual curiosity by communicating interesting information. So soon as this information ceased to be interesting, the value of their work was gone. Thus although accident has handed down several specimens of the Alexandrine type of didactic poetry, their chief literary use is to enable us, by contrast, better to appreciate the genius which, by interfusing with the materials used by them other elements deeply affecting the heart, the imagination, and the moral sympathies, has given the world, instead of the temporary gift of a little useful information, the κτῆμα ἐς ἀεί which it possesses in the Georgics.
In that poem Virgil combines something of the spirit of the older or primitive type of didactic poetry with the systematic treatment of their subject employed by the Alexandrine Metaphrastae. He retains the old form of a personal address, not only in the dedication of the poem to Maecenas, but in the manner in which he inculcates his precepts on the husbandman, or indicates what he himself would do in particular circumstances[281]. Yet he bears more resemblance to the poets of Alexandria in his systematic treatment and arrangement of [pg 184]his materials. He aims, like them, at communicating a large body of unfamiliar knowledge, as well as conveying practical precepts founded on experience. By combining these two aims, but much more by making the aims of conveying precept and instruction altogether subsidiary to that of moving the imagination and the affections, Virgil, if he has not created a new type of didactic poetry, has at least produced almost the only specimen of it which the world cares to read. He is apparently conscious of the difficulty of imparting to a poem of this type a continuous poetical charm; as Lucretius, with more reason, is conscious of the difficulty of securing a sustained poetical interest for his argumentative processes and his investigations into the first principles of things. Virgil’s difficulty is to maintain his subject on the level of poetical feeling, while at the same time adhering to the necessities of practical instruction. And this difficulty attaches to every kind of didactic poetry. He had to associate with a poetic charm, not only the fair results of the husbandman’s labour, the ‘heavy harvests and the Massic juice of the vine,’ but the processes and mechanical appliances through which these fair results were obtained. Although his idea of his art did not demand an exhaustive treatment of all the operations of rural industry, such as was demanded of the prose writers on the subject, yet it did demand that, in making his selection, he should regard the importance of each topic in connexion with the work of the farm as well as its adaptation to poetic treatment. It cannot be denied that this necessary infusion of prosaic matter deprives even the most perfect specimen of didactic poetry of that purity of imaginative interest which pervades the masterpieces of epic, lyrical, and dramatic genius: but it is, on the other hand, a great triumph of art to have redeemed so much as Virgil has done from the homely realities of life into the more sacred ground of poetry, and that without sacrifice either of the truth of fact or of the dignity and sobriety of expression.
