Event Comment: The Duke's Company. This performance is on the L. C. list, 5@141, p. 216. See also Nicoll, Restoration Drama, p. 348. There is considerable uncertainty as to when the first performance occurred, but it appears to have been acted first at court. See Boswell, Restoration Court Stage, pp. 131-34. The first Prologue, written by Lord Mulgrove, and the second, written by Lord Rochester, are in A Collection of Poems Written upon several Occasions by several Persons (1673). Roger North: And now we turne to the Publik theatres. It had bin strange if they had not observed this promiscuous tendency to musick, and not have taken it into their scenes and profited by it. The first proffer of theirs, as I take it, was in a play of the thick-sculd-poetaster Elkanah Settle, called The Empress of Morocco; which had a sort of masque poem of Orfeus and Euridice, set by Mr M. Lock, but scandalously performed. It begins The Groans of Ghosts, &c. and may be had in print (Roger North on Music, ed. John Wilson [London, 1959], p. 306)

Event Comment: The United Company. The date of the first performance is not known, but it very probably occurred not later than May 1691, as the play was advertised in the London Gazette, 4-8 June 1691. For discussions of it, see E. W. White, Early Performances of Purcell's Operas, Theatre Notebook, XIII (1958-59), 44-45, and R. E. Moore, Henry Purcell and the Restoration Theatre, Chapter III. Downes, Roscius Anglicanus, p. 42: King Arthur an Opera, wrote by Mr Dryden: it was Excellently Adorn'd with Scenes and Machines: The Musical Part set by Famous Mr Henry Purcel; and Dances made by Mr Jo. Priest: The Play and Musick pleas'd the Court and City, and being well perform'd, twas very Gainful to the Company. Roger North: I remember in Purcell's excellent opera of King Arthur, when Mrs Butler, in the person of Cupid, was to call up Genius, she had the liberty to turne her face to the scean, and ner back to the theater. She was in no concerne for her face, but sang a recitativo of calling towards the place where Genius was to rise, and performed it admirably, even beyond any thing I ever heard upon the English stage....And I could ascribe it to nothing so much as the liberty she had of concealing her face, which she could not endure should be so contorted as is necessary to sound well, before her gallants, or at least her envious sex. There was so much of admirable musick in that opera, that it's no wonder it's lost; for the English have no care of what's good, and therefore deserve it not (Roger North on Music, ed. John Wilson [London, 1959], p. 217-18)
