enters into the lists like a new wrestler, to dispute the prize with the former champion. This sort of emulation, says Hesiod, is honourable, [Greek: Agathe d' eris esti Brotoisin]--when we combat for victory with a hero, and are not without glory even in our overthrow. Those great men, whom we propose to ourselves as patterns of our imitation, serve us as a torch, which is lifted up before us, to enlighten our passage, and often elevate our thoughts as high as the conception we have of our author's genius." I have been so tedious in three acts, that I shall contract myself in the two last. The beginning scenes of the fourth act are either added or changed wholly by me; the middle of it is Shakespeare altered, and mingled with my own; three or four of the last scenes are altogether new. And the whole fifth act, both the plot and the writing, are my own additions. But having written so much for imitation of what is excellent, in that part of the preface which related only to myself, methinks it would neither be unprofitable nor unpleasant to inquire how far we ought to imitate our own poets, Shakespeare and Fletcher, in their tragedies; and this will occasion another inquiry, how those two writers differ between themselves: but since neither of these questions can be solved, unless some measures be first taken, by which we may be enabled to judge truly of their writings, I shall endeavour, as briefly as I can, to discover the grounds and reason of all criticism, applying them in this place only to Tragedy. Aristotle with his interpreters, and Horace, and Longinus, are the authors to whom I owe my lights; and what part soever of my own plays, or of this, which no mending could make regular, shall fall under the condemnation of such judges, it would be impudence in me to defend. I think it no shame to retract my errors, and am well pleased to suffer in the cause, if the art may be improved at my expence: I therefore proceed to THE GROUNDS OF CRITICISM IN TRAGEDY.
