Event Comment: The United Company. Tne date of the first performance is not known, but the Gentleman's Journal, March 1692 (licensed 9 March 1691@2), refers to its having already been produced. See also a letter concerning it dated 19 Jan. 1691@2. Probably the play was given in early February 1692. A song, How long must women wish in vain, the music by Robert King, is in Comes Amoris, The Fourth Book, 1693. Gentleman's Journal, March 1692: We have had lately a new Play, called, The Innocent Impostors. It hath been acted four times. Mr Shadwell Poet-Laureat, usher'd it into the Stage. It is said that the Author of it is not one of the Laity; therefore since he desires not to be known, I shall not presume to let you know his Name, tho the Play being Historical, and altogether of the Tragick kind, and withal treated with all the decency imaginable, can never be inglorious to its ingenious Author

Event Comment: Betterton's Company. The date of the premiere is not known, but Dryden, on 14 Dec. 1699, indicated that the run of the play had been completed by that day.

[In The Life of Mr John Dennis (London, 1734) the author states that Colonel Codrington prevailed on all his friends to take tickets for the dramatist's third night.] Preface, Edition of 1700: And from the first representations I expected all the success that I could reasonably desire.

But after three or four representations, several people, who during that time had wholly abandon'd themselves to the Impression which Nature had made on them, began to study how to be discontented by Art; and repented heartily at having been pleas'd with what Athens and Rome and Paris had been pleas'd before. A Comparison between the Two Stages (1702), p. 23: Critick: I must needs Complement him [Dennis] with the Success of his laborious Iphigenia: Ay, here's a Tragedy with a witness--show a more tragick Poet if you can--'twas a smart Epilogue. But I marvel a Man of Mr Dennis's Penetration wou'd suffer, nay beg his Friend to Burlesque him at that unreasonable rate: But the Author was conscious the Audience might mistake it for a Comedy, and so he gets Colonel C-(he was sure his Word wou'd be taken) to tell 'em it was not a Comedy but a Tragedy: The hint was good and necessary, for o' my word very few knew what to make of it before, tho' there were many Tremendous things in't.
