In pompous introductions, These preparatory observations, concerning the laws of poetic composition at large, have been thought to glance more particularly at the epic poetry which was not improper: for, 1. the drama which he was about to criticise, had its rise and origin from the epos. Thus we are told by the great critic, that Homer was the first who invented dramatic imitations μόνοσ . 2. The several censures, here pointed at the epic, would bear still more directly against the tragic poem; it being more glaringly inconsistent with the genius of the drama to admit of foreign and digressive ornaments, than of the extended, episodical epopaeia. For both these reasons, it was altogether pertinent to the poet's purpose, in a criticism on the drama, to expose the vicious practice of the epic models. Though, to preserve the unity of his piece, and for a further reason (see note on v. 1), he hath artfully done this under the cover of general criticism. and such as promise a great deal, it generally happens that one or two verses of purple patch-work, that may make a great show, are tagged on; as when the grove and the altar of Diana and the meandering of a current hastening through pleasant fields, or the river Rhine, or the rainbow is described. But here there was no room for these [fine things]: perhaps, too, you know how to draw a cypress: Boughs of cypress were carried in funeral processions, and placed before the houses of the great, upon particular occasions of sorrow, Et non plebeios luctus testata cupressus. Lucan. From hence, perhaps, this tree was usually drawn in votive tablets; in pictures carried by beggars, to excite charity; and in those used by lawyers in courts of justice, to raise the compassion of the judges, by representing the distresses of their clients. A painter might, by frequent practice, excel in drawing a tree for which there was such demand; and he therefore absurdly determines to show his skill upon all occasions, even by painting it in the middle of the ocean, and making it overshadow the storm. The commentators understand this passage in a different manner. but what is that to the purpose, if he, who is painted for the given price, is [to be represented as] swimming hopeless out of a shipwreck? A large vase at first was designed: why, as the wheel revolves, turns out a little pitcher? In a word, be your subject what it will, let it be merely simple and uniform.
