This fine induction can hardly have formed part of the original essay, which, Dryden tells us, was written in the country in 1665, since the naval battle, which was fought on June 3rd, 1665, is described as having taken place in 'the first summer of the late war.' One extraordinary passage must have been left uncorrected by oversight, at least we cannot well suppose that Dryden would have printed 'Blank verse is acknowledged to be too low for a poem' after the appearance of _Paradise Lost_, which was published on the day after the conclusion of the Peace of Breda, not then known in England. The essay has two objects not very compatible: to defend the English stage against the French, and to advocate the use of rhyme in tragedy, which necessarily gives the piece a French air, and makes it appear imitative, when it is in truth original. Dryden points out with considerable force the restrictions which French dramatists of the classical school impose upon themselves by servile adherence to the unities of time and place, and in a well-known passage which does honour to his taste sets Shakespeare above Ben Jonson. His criticism of _Troilus and Cressida_, in his essay on _The Grounds of Criticism in Tragedy_ (1679), is instructive as illustrating by force of contrast that enlarged view of Shakespeare for which we are indebted to Goethe and Coleridge. He justly censures _Troilus and Cressida_ as a play; it does not occur to him that Shakespeare may have intended a satire. All his essays, which consist principally of prefaces and dedications to his own works, are worth reading; none more so than his defence of Virgil in the dedication to his translation of his poems, and the remarks on Horace and Juvenal in his _Essay on Satire_. Everywhere we must admire his sanity, penetration, and massive common sense; his chief defects are conventional prejudice, negligence (as when he ascribes the invention of blank verse to Shakespeare), and the parade of second-hand learning. It may be said of his criticisms, as truly as of his poems or plays, that his merits are his own, his faults those of his age.
