Generations, much as Nonnus has done with St. John, and yet often miss'd his Sence too, as Heinsius judges. But enough of Fable, and of those who would either reduce all Heroic Poetry unto it, or absolutely banish it thence. Next the Fable of Epics, the Poem is to be considered; which, after Bossu, is the other part of its general Nature, and shews the manner of handling it, comprehending Thoughts, Expressions and Verses; of which there need not much be said, since they are obvious to every Reader. The Thoughts must be clear and just, and noble, and the Diction or Expression suited to them. The chief Difficulty, as Rapin observes, is to keep up the Sublime, which Virgil has done admirably, even in the meanest Subjects; and which Aristotle thinks may be best done by the judicious use of Metaphors. There ought to meet, according to him, Proportion in the Design, Justness in the Thoughts, and Exactness in the Expression, to constitute an accomplish'd Heroic Poem; and the great Art of Thought and Expression lies in this, that they be natural and proper without Meanness, and sublime without a vitious Swelling and Affectation. The Matter is next in an Heroic Poem, which must be one important Action; it must be important, Res gestae Regumque Ducumque, with Horace. "It only speaks of Kings and Princes," says Rapin, by which he must mean that it chiefly and principally turns upon them: for both Virgil and Homer have occasion for Traitors, and Cryers, and Beggars, nay even Swineherds (in the Odysses), and yet still more, of whole Armies, which can't be all compos'd of Kings and Princes. However, the more there is of these lower Walks in the Plan of a Design, the less Heroic it must appear, even in the Hands of the greatest Genius in Nature. Such a Genius, I think, was Homer's, and yet the Truth of this Assertion will be plain to any who compares his Odysses with his Iliads; where he'll find, if 'tis not for want of Judgment, in the latter a very different Air from the former, in many places much more dead and languishing, and this which I have given, seems one probable Reason on't; not excluding that of Longinus, that Homer was then grown old, and besides too much of the Work was spent in Narration; to which may be added, that he here design'd a wise and prudent rather than a brave and fighting Hero, having wrought off most of the Edg and Fury of his Youthful Spirit and Fury in Achilles, as in Ulysses he express'd more of Age and Judgment.
