Purcell’s fourth and last full-scale semi-opera, The Indian Queen, is often passed over in favour of its longer and more rounded predecessors, especially King Arthur and The Fairy Queen. The reasons are plentiful: Thomas Betterton, with whom Purcell collaborated, never finished his reworking of an early Restoration tragedy and even if he had torn himself away from his business interests in 1695, Purcell would not have been alive to set the remaining music for Act 5. As it happened, Henry’s brother Daniel set the masque from the final act after Betterton had hired an anonymous writer to finish his adaptation. No one can deny that neither verse nor music achieved the heights imagined in the original collaboration; given the quality of the masques in Purcell’s large ‘dramatick’ operas (including Dioclesian, of course), there is an undoubted sense of anticlimax.
