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 (
