The beauty of a didactic poem depends only partially on the just views and correct discrimination which it evinces, and principally on the beauty of the language, the picturesque force, and pleasing character of the descriptions, and the interest that is thrown into the episodes. In fact, the accessaries are the parts most admired, and extracts brought forward as specimens of this kind of poetry are invariably of this kind. Poetry naturally deals with the beauties and terrors of external nature—with the emotions and passions, whether of a tender or violent kind—the sober practical rules of life are scarcely within its sphere. True it is that when all literature was poetical, the precepts of moral and physical philosophy, and even the dry commands of laws and institutions, were embodied in a metrical form; but when literature divides itself into poetry and prose, the subjects appropriated to each other become spontaneously separate likewise. For this reason, the Georgics of Virgil especially display his ability as a poet, his correct taste the “limæ labor,” the pains which he took in polishing and correcting. In none of his poems can we form a better idea of the description which he gives of his patient toil, when he says, that “like the she-bear he brought his poetical offspring into shape by constantly licking them.”[564] The majesty of the language elevates the subject, and divests it of so much of the homeliness as would be inappropriate to poetry, and yet at the same time it is not too grand or elevated. The following criticism of Addison[565] is by no means too favourable:—“I shall conclude this poem to be the most complete, elaborate, and finished piece of all antiquity. The Æneis is of a nobler kind; but the Georgic is more perfect in its kind. The Æneis has a greater variety of beauties in it; but those of the Georgic are more exquisite. In short, the Georgic has all the perfection that can be expected in a poem written by the greatest poet, in the flower of his age, when his invention was ready, his imagination warm, his judgment settled, and all his faculties in their full vigour and maturity.”
