In Tragedy he was the most affecting Lover within my Memory. His Addresses had a resistless Recommendation from the very Tone of his Voice ... All this he particularly verify'd in that Scene of _Alexander_, where the Heroe throws himself at the Feet of _Statira_ for Pardon of his past Infidelities. There we saw the Great, the Tender, the Penitent, the Despairing, the Transported, and the Amiable, in the highest Perfection (_Apology_, pp. 74-75). Mountfort's third play was acted in January, 1690, although it may have been produced as early as December of the previous year. _The Successful Strangers_, a tragi-comedy, was based on a novel by Scarron, _The Rival Brothers_. In his Preface, Mountfort confesses, "_I am no Scholar, which renders me incapable of stealing from Greek and Latin Authors, as the better Learned have done_". The play was a success; its combination of comedy and tragedy appealed to the town, and it was revived several times in the early eighteenth century. As Borgman notes (p. 80), Mountfort's acting career peaked in the season of 1690-1691, when he acted nine new roles, eight of which were leads. He also prepared a comedy of his own, _Greenwich Park_, and assisted in the writing or preparation of three other plays. He assisted Settle with _Distress'd Innocence_, and his name is linked with two plays by John Bancroft, _Edward III_ and _Henry the Second_, although his contribution here, if any, is uncertain. The publishers of the collected plays of 1720 note that "we have annex'd, _King Edward the Third_, and _Henry the Second_; which tho' not wholly composed by him, it is presum'd he had, at least, a Share in fitting them for the Stage, otherwise it cannot be supposed he would have taken the Liberty of Writing Dedications to them." Borgman says of these plays that Mountfort "doubtless scanned the script with a critical eye and made such changes as would seem necessary to an experienced man of the theater" (p. 90).
