4. DIDACTIC POETRY.--The poems, which first established the reputation of Virgil as a poet, belong to didactic poetry. They are his Bucolics and Georgics. The Bucolics are pastoral idyls; the characters are Italian in all their sentiments and feelings, acting, however, the unreal and assumed part of Greek shepherds. The Italians never possessed the elements of pastoral life, and could not furnish the poet with originals and models from which to draw his portraits. When represented as Virgil represents them in his Bucolics, they are in masquerade, and the drama in which they form the characters is of an allegorical kind. Even the scenery is Sicilian, and does not truthfully describe the tame neighborhood of Mantua. In fact, these poems are imitations of Theocritus; but, divesting ourselves of the idea of the outward form which the poet has chosen to adopt, we are touched by the simple narrative of disappointed loves and childlike woes; we appreciate the delicately-veiled compliments paid by the poet to his patron; we enjoy the inventive genius and poetical power which they display, and we are elevated by the exalted sentiments which they sometimes breathe. The Georgics are poems on the labors and enjoyments of rural life, a subject for which Rome offered a favorable field. Though in this style Hesiod was the model of Virgil, his system is perfectly Italian, so much so, that many of his rules may be traced in modern Italian husbandry, just as the descriptions of implements in the Greek poet are frequently found to agree with those in use in modern Greece. The great merit of the Georgics consists in their varied digressions, interesting episodes, and in the sublime bursts of descriptive vigor which are interspersed throughout them. They have frequently been taken as models for imitation by the didactic poets of all nations, and more particularly of England. The "Seasons," for instance, is a thoroughly Virgilian poem. Lucretius (95-51 B.C.) belongs to the class of didactic poets. He might claim a place among philosophers as well as poets, for his poem marks an epoch both in poetry and philosophy. But his philosophy is a mere reflection from that of Greece, while his poetry is bright with the rays of original genius. His poem on "The Nature of Things" is in imitation of that of Empedocles. Its subject is philosophical and its purpose didactic; but its unity of design gives to it almost the rank of an epic. Its structure prevents it from being a complete and systematic survey of the whole Epicurean philosophy, but as far as the form of the poem permitted, it presents an accurate view of the philosophy which then enjoyed the highest popularity.
