He that succeeds a celebrated writer, has the same difficulties to encounter; he stands under the shade of exalted merit, and is hindered from rising to his natural height, by the interception of those beams which should invigorate and quicken him. He applies to that attention which is already engaged, and unwilling to be drawn off from certain satisfaction; or perhaps to an attention already wearied, and not to be recalled to the same object.
One of the old poets congratulates himself that he had the untrodden regions of Parnassus before him, and that his garland will be gathered from plantations which no writer had yet culled. But the imitator treads a beaten walk, and with all his diligence can only hope to find a few flowers or branches untouched by his predecessor, the refuse of contempt, or the omissions of negligence. The Macedonian conqueror, when he was once invited to hear a man that sung like a nightingale, replied with contempt, "that he had heard the nightingale herself;" and the same treatment must every man expect, whose praise is that he imitates another.
Yet, in the midst of these discouraging reflections, I am about to offer to my reader some observations upon "Paradise Lost," and hope, that, however I may fall below the illustrious writer who has so long dictated to the commonwealth of learning, my attempt may not be wholly useless. There are, in every age, new errours to be rectified, and new prejudices to be opposed. False taste is always busy to mislead those that are entering upon the regions of learning; and the traveller, uncertain of his way, and forsaken by the sun, will be pleased to see a fainter orb arise on the horizon, that may rescue him from total darkness, though with weak and borrowed lustre.
Addison, though he has considered this poem under most of the general topicks of criticism, has barely touched upon the versification; not probably because he thought the art of numbers unworthy of his notice, for he knew with what minute attention the ancient criticks considered the disposition of syllables, and had himself given hopes of some metrical observations upon the great Roman poet; but being the first who undertook to display the beauties, and point out the defects of Milton, he had many objects at once before him, and passed willingly over those which were most barren of ideas, and required labour, rather than genius.
Yet versification, or the art of modulating his numbers, is indispensably necessary to a poet. Every other power by which the understanding is enlightened, or the imagination enchanted, may be exercised in prose. But the poet has this peculiar superiority, that to all the powers which the perfection of every other composition can require, he adds the faculty of joining music with reason, and of acting at once upon the senses and the passions. I suppose there are few who do not feel themselves touched by poetical melody, and who will not confess that they are more or less moved by the same thoughts, as they are conveyed by different sounds, and more affected by the same words in one order than in another. The perception of harmony is indeed conferred upon men in degrees very unequal, but there are none who do not perceive it, or to whom a regular series of proportionate sounds cannot give delight.
In treating on the versification of Milton, I am desirous to be generally understood, and shall therefore studiously decline the dialect of grammarians; though, indeed, it is always difficult, and sometimes scarcely possible, to deliver the precepts of an art, without the terms by which the peculiar ideas of that art are expressed, and which had not been invented but because the language already in use was insufficient. If, therefore, I shall sometimes seem obscure, it may be imputed to this voluntary interdiction, and to a desire of avoiding that offence which is always given by unusual words.
The heroick measure of the English language may be properly considered as pure or mixed. It is pure when the accent rests upon every second syllable through the whole line.
