it may be inferred that his first idea was to make the contemporaneous events the main subject of his epic, and to introduce the glories of the Trojan line as accessories. Under what influence he changed this purpose, making contemporary events subsidiary and the ancient legend the main argument of his poem, will be considered in the chapters devoted to the examination of the Aeneid.
IV.
As affecting the arrangement and illustration of their materials, there is this essential difference between the poems of Lucretius and Virgil, that the one is a great continuous argument, the development of speculative truths depending on one another; and its professed aim is purely contemplative,—the production of a certain state of mind and feeling. The other is the orderly exposition of a number of precepts, depending on experience and special knowledge; its professed aim is the mastery over a great practical occupation. Lucretius uses poetry as the vehicle of science, Virgil as the instrument of a useful art. In the first we expect, and we find, in so far as the poem was left completed, rigorous concentration of thought, and an exhaustive treatment of the subject. In the second we expect, and we find, an orderly and convenient arrangement, and such a selection of topics as, while producing the impression of a thorough mastery of the subject, leaves also much to be filled up by the imagination or experience of the reader. Still, that Virgil regarded Lucretius as his technical model may be inferred from the use which he makes of several of his formulae, such as ‘Principio,’ ‘Quod superest,’ ‘His animadversis,’ ‘Nunc age,’ ‘Praeterea,’ by which the framework of his argument is held together. Virgil uses these more sparingly, and with a more careful selection, so as, while producing the impression of continuity of thought, not to impede the pure flow of his poetry with the mechanism of logical connexion. He follows Lucretius also, who here observed the practice of the Greek didactic poets, in maintaining the liveliness of a personal address by the frequent use of such appeals as these, ‘Nonne vides,’ ‘Contemplator,’ ‘Forsitan et ... quaeras,’ ‘Vidi,’ ‘Ausim,’ etc.
In illustrating and giving novelty to his various topics Virgil has the example of Lucretius to justify him in catching up and dwelling on every aspect of beauty or imaginative interest which they are capable of presenting. And it is here that the [pg 230]more careful art of Virgil, and the fact that he attached more value to the perfection of his art than to the knowledge he imparts, give him that technical superiority over the older writer which, notwithstanding the tamer interest of his subject, and perhaps the tamer character of his own genius, has made the Georgics a poem much more familiar to the world than the ‘De Rerum Natura.’ Virgil, for one thing, enjoys greater freedom of omitting any set of topics,—any of those details on which Cato or Varro would have felt themselves bound to be specially explicit,—which would detract unduly from the beauty and general amenity of his exposition; or by a simple touch (such as the ‘Ne saturare fimo pingui,’ etc.) he can suggest the necessity of attending to such topics, while leaving their full realisation to the reader. He thus, by greater selection and elimination of his materials, avoids the monotony and the long prosaic interspaces between the grander bursts of poetry which his vast argument imposes on Lucretius. But, further, he avails himself of many more resources to give variety of interest and literary charm to the topics which he successively deals with. Each and all of these topics,—the processes of ploughing and sowing, the signs of the weather, the grafting of trees and the pruning of the vine, the qualities of horses and cattle, the tending of sheep and goats, the observation of the habits of bees,—bring him into immediate contact with the genial influences of the outward world. The vastness as well as the abstract character of his subject forces Lucretius to pass through many regions which seem equally removed from this genial presence and from all human associations. It is only the enthusiasm of discovery—the delight in purely intellectual processes—that bears him buoyantly through these dreary spaces; and it is only the knowledge that from time to time glimpses of illimitable power and wonder are opened up to him, and admiration for the energy and clear vision of his guide, that compel the flagging reader to accompany him. But Virgil leads his readers through scenes, tamer indeed and more familiar, yet always bright and smiling with some homely charm, or rich and glowing with the ‘pomp [pg 231]of cultivated nature,’ or fresh and picturesque with the charm of meadow, river-bank, or woodland pasture.
The secret of the power of Lucretius as an interpreter of Nature lies in his recognition of the sublimity of natural law in ordinary phenomena. The secret of Virgil’s power lies in the insight and long-practised meditation through which he abstracts the single element of beauty from common sights and the ordinary operations of industry. Thus, to take one or two instances of the way in which the charm of Nature is communicated to the drudgery of rural labour:—what a sense of refreshment to eye and ear is conveyed by the lines which describe the practical remedies by which the farmer mitigates the burning drought of summer:—
Et cum exustus ager morientibus aestuat herbis,
Ecce supercilio clivosi tramitis undam
Elicit; illa cadens raucum per levia murmur
Saxa ciet, scatebrisque arentia temperat arva[347].
