Dryden held a distinguished situation; for about 1675 he was, as we shall presently see, sufficiently in Sheffield’s confidence to correct and revise that nobleman’s poetry;[1] and in 1676 dedicated to him the tragedy of “Aureng-Zebe,” as one who enjoyed not only his favour, but his love and conversation.  Thus Dryden was obnoxious to Rochester, both as holding a station among the authors of the period, grievous to the vanity of one who aimed, by a levelling and dividing system, to be the tyrant, or at least the dictator, of wit; and also as the friend, and even the confidant, of Mulgrave, by whom the witty profligate had been baffled and humiliated.  Dryden was therefore to be lowered in the public opinion; and for this purpose, Rochester made use of Elkanah Settle, whom, though he gratified his malice by placing him in opposition to Dryden, he must, in his heart, have thoroughly despised.[2]

This playwright, whom the jealous spleen of a favourite courtier, and the misjudging taste of a promiscuous audience, placed for some time in so high a station, came into notice in 1671, on the representation of his first play, “Cambyses, King of Persia,” which was played six nights successively.  This run of public favour gave Rochester some pretence to bring Settle to the notice of the king; and, through the efforts of this mischievous wit, joined to the natural disposition of the people to be carried by show, rant, and tumult, Settle’s second play, “The Empress of Morocco,” was acted with unanimous and overpowering applause for a month together.  To add to Dryden’s mortification, Rochester had interest enough to have this tragedy of one whom he had elevated into the rank of his rival, first acted at Whitehall by the lords and ladies of the court; an honour which had never been paid to any of Dryden’s compositions, however more justly entitled to it, both from intrinsic merit, and by the author’s situation as poet-laureate.  Rochester contributed a prologue upon this brilliant occasion to add still more grace to Settle’s triumph; but what seems yet more extraordinary, and has, I think, been unnoticed in all accounts of the controversy, Mulgrave,[3] Rochester’s rival and the friend of Dryden, did the same homage to “The Empress of Morocco.”  From the king’s private theatre, “The Empress of Morocco” was transferred, in all its honours, to the public stage in Dorset Gardens, and received with applause corresponding to the expectation excited by its favour at Whitehall.  While the court and city were thus worshipping the idol which Rochester had set up, it could hardly be expected of poor Settle, that he should be first to discern his own want of desert.  On the contrary, he grew presumptuous on success; and when he printed his performance, the dedication to the Earl of Norwich was directly levelled against the poet-laureate who termed it the “most arrogant, calumniatory, ill-mannered, and senseless preface he ever saw."[4] And, to add gall to bitterness, the bookseller thought “The Empress of Morocco” worthy of being decorated with engravings, and sold at the advanced price of two shillings; being the first drama advanced to such honourable distinction.[5] Moreover, the play is ostentatiously stated in the title to be written by Elkanah Settle, Servant to His Majesty;[6] an addition which the laureate had assumed with greater propriety.
