The Relapse was the first Play our Author produced, but not the first he had written; for he had at that Time by him, all the Scenes of The Provok'd Wife; but being then doubtful whether he should ever trust it to the Stage, he flung it by, and thought no more of it: Why the last written Play was first acted, and for what Reason they were given to different Stages, what follows will explain.

Upon our Author's first Step into public Life, when he was but an Ensign in the Army, and had a Heart greatly above his Income, he happened somewhere at his Winter Quarters, upon a slender Acquaintance with Sir Thomas Skipwith, to receive a particular Obligation from him; and many Years afterwards, when Sir Thomas's Interest in a Theatrical Patent (which he had a large Share in, though he little concerned himself in the Conduct of it) was rising but very slowly, Sir John thought that to give it a lift by a new Comedy, might be the handsomest Return he could make to those his former Favours; accordingly he soon after finished The Relapse, or, Virtue in Danger, which was acted at the Theatre in Drury-Lane, in 1696, with universal Applause.

Upon the Success of The Relapse, the late Lord Hallifax, who was a favourer of Betterton's Company, having formerly heard some Scenes of The Provok'd Wife read to him, engaged Sir John Vanbrugh to revise it, and give it to that Company. This was a Request not to be refused to so eminent a Patron of the Muses as Lord Hallifax, who was equally a Friend and Admirer of Sir John himself; nor was Sir Thomas Skipwith in the least disobliged by so reasonable a Compliance. The Provok'd Wife was accordingly acted at the Theatre in Lincoln's Inn-Fields in 1697, with great Success.

Tho' this Play met with so favourable a Reception, yet it was not without its Enemies: People of the graver Sort blamed the looseness of the Scenes, and the unguarded freedom of the Dialect; and indeed Sir John himself appears to have been sensible of the immorality of his Scenes; for in the Year 1725, when this Play was revived, he thought proper to substitute a new Scene in the fourth Act, in place of another, in which, in the wantonness of his Wit, he had made a Rake talk like a Rake, in the Habit of a Clergyman; to avoid which Offence, he put the same Debauchee into the Undress of a Woman of Quality; by which means the Follies he exposed in the Petticoat, appeared to the Audience innocent and entertaining; which new Scene is now for the first Time printed at the End of the Play.

Soon after the Success of The Provok'd Wife, Sir John produced the Comedy of Esop, in two Parts, which was acted at the Theatre-Royal in Drury Lane, in 1697. This was originally written in French by Mr. Boursaut, about six Years before; but the Scenes of Sir Polydorus Hogstye, the Players, and the Beau, were added by our Author. This Play contains a great deal of general Satire, and useful Morality; notwithstanding which, it met with but a cold Reception from the Audience, and its run ended in about nine Days. This seemed the more surprizing, as the French Comedy was played to crowded Audiences for a Month together. The little Success this Piece met with on the English Stage, cannot be better accounted for than in the Words of Mr. Cibber, who, speaking of this Play, makes the following Observation: "The Character that delivers Precepts of Wisdom, is in some sort severe upon the Auditor, for shewing him one wiser than himself; but when Folly is his Object, he applauds himself for being wiser than the Coxcomb he laughs at; and who is not more pleased with an Occasion to commend, than to accuse himself?"

The next Play our Author wrote, was The False Friend, a Comedy, which was acted at the Theatre-Royal in Drury Lane, in 1702.

In 1703, Sir John formed a Project of building a stately Theatre in the Haymarket, for which he had interest enough to get a Subscription of thirty Persons of Quality, at one hundred Pounds each, in consideration whereof, every Subscriber was for his own Life to be admitted to whatever Entertainments should be publicly performed there, without any farther Payment for Entrance.

In 1706, when this House was finished, Mr. Betterton and his Co-partners, who then acted at the Theatre in Lincoln's Inn-Fields, dissolved their Agreement, and put themselves under the direction of Sir John Vanbrugh and Mr. Congreve, imagining, perhaps, that the Conduct of two such eminent Authors might give a more prosperous turn to their Affairs; that the Plays it would now be their interest to write for them, would soon recover the Town to a true Taste, and be an Advantage that no other Company could hope for; and that till such Plays could be written, the Grandeur of their House, as it was a new spectacle, might allure the Crowd to support them: But, if these were their Views, they soon found their Dependance upon them was too sanguine; for though Sir John was a very expeditious Writer, yet Mr. Congreve was too judicious to let any Thing come unfinished from his Pen. Besides, every proper Convenience of a good Theatre had been sacrificed to shew the Audience a vast triumphal Piece of Architecture, in which, by Means of the spaciousness of the Dome, plays could not be successfully represented, because the Actors could not be distinctly heard.

Not long before this Time, the Italian Opera began to steal into England, but in as rude a Disguise as possible: notwithstanding which, the new Monster pleased, though it had neither Grace, Melody, nor Action, to recommend it. To strike in therefore with the prevailing Fashion, Sir John and Mr. Congreve opened their New Theatre with a translated Opera, set to Italian Music, called The Triumph of Love; but it met with a very cool Reception, being performed only three Times—to thin Houses.
