of arts, and the whole compass of nature, to supply his maxims and reflections; all the inward passions and affections of mankind, to furnish his characters: and all the outward forms and images of things for his descriptions: but wanting yet an ampler sphere to expatiate in, he opened a new and boundless walk for his imagination, and created a world for himself in the invention of fable. That which Aristotle calls "the soul of poetry," was first breathed into it by Homer, I shall begin with considering him in his part, as it is naturally the first; and I speak of it both as it means the design of a poem, and as it is taken for fiction. Fable may be divided into the probable, the allegorical, and the marvellous. The probable fable is the recital of such actions as, though they did not happen, yet might, in the common course of nature; or of such as, though they did, became fables by the additional episodes and manner of telling them. Of this sort is the main story of an epic poem, "The return of Ulysses, the settlement of the Trojans in Italy," or the like. That of the Iliad is the "anger of Achilles," the most short and single subject that ever was chosen by any poet. Yet this he has supplied with a vaster variety of incidents and events, and crowded with a greater number of councils, speeches, battles, and episodes of all kinds, than are to be found even in those poems whose schemes are of the utmost latitude and irregularity. The action is hurried on with the most vehement spirit, and its whole duration employs not so much as fifty days. Virgil, for want of so warm a genius, aided himself by taking in a more extensive subject, as well as a greater length of time, and contracting the design of both Homer's poems into one, which is yet but a fourth part as large as his. The other epic poets have used the same practice, but generally carried it so far as to superinduce a multiplicity of fables, destroy the unity of action, and lose their readers in an unreasonable
