Previous to 1678, Lord Mulgrave, our author's constant and probably effectual patron, had given him an opportunity of discoursing over his plan of an epic poem to the king and Duke of York; and in the preface to "Aureng-Zebe" in that year, the poet intimates an indirect complaint that the royal brothers had neglected his plan.[37] About two years afterwards, Mulgrave seems himself to have fallen into disgrace, and was considered as in opposition to the court.[38] Dryden was deprived of his intercession, and seems in some degree to have shared his disgrace. The "Essay on Satire" became public in November 1679, and being generally imputed to Dryden, it is said distinctly by one libeller, that his pension was for a time interrupted.[39] This does not seem likely; it is more probable, that Dryden shared the general fate of the household of Charles II., whose appointments were but irregularly paid; but perhaps his supposed delinquency made it more difficult for him than others to obtain redress. At this period broke out the pretended discovery of the Popish Plot, in which Dryden, even in "Absalom and Achitophel," evinces a partial belief.[40] Not encouraged, if not actually discountenanced, at court; sharing in some degree the discontent of his patron Mulgrave; above all, obliged by his situation to please the age in which he lived, Dryden did not probably hold the reverence of the Duke of York so sacred, as to prevent his making the ridicule of the Catholic religion the means of recommending his play to the passions of the audience. Neither was his situation at court in any danger from his closing on this occasion with the popular tide. Charles, during the heat of the Popish plot, was so far from being in a situation to incur odium by dismissing a laureate for having written a _Protestant play_, that he was obliged for a time to throw the reins of government into the hands of those very persons to whom the Papists were most obnoxious. The inference drawn from Dryden's performance was that he had deserted the court; and the Duke of York was so much displeased with the tenor of the play, that it was the only one of which, on acceding to the crown, he prohibited the representation. The "Spanish Friar" was often objected to the author by his opponents, after he had embraced the religion there satirised. Nor was the idea of his apostasy from the court an invention of his enemies after his conversion, for it prevailed at the commencement of the party-disputes; and the name of Dryden is, by a partisan of royalty, ranked with that of his bitter foe Shadwell, as followers of Shaftesbury in 1680.[41] But whatever cause of coolness or disgust our author had received from Charles or his brother, was removed, as usual, so soon as his services became necessary; and thus the supposed author of a libel on the king became the ablest defender of the cause of monarchy, and the author of the "Spanish Friar" the advocate and convert of the Catholic religion.
