Kenilworth, A Masque of the Days of Queen Elizabeth (commonly referred to as "The Masque at Kenilworth"), is a cantata with music by Arthur Sullivan and words by Henry Fothergill Chorley (with an extended Shakespeare quotation) that premiered at the Birmingham Festival on 8 September 1864.
In 1575, Queen Elizabeth visited Robert Dudley at Kenilworth Castle, where he presented her with lavish entertainments over a period of 19 days in an attempt to persuade her to marry him. This piece attempts to recreate the sort of masque that might have been performed for the queen's pleasure. The text is based partly on the description of the queen's visit in the 1821 novel Kenilworth, by Sir Walter Scott and on other contemporary accounts and fiction.
