Patience; or, Bunthorne's Bride, is a comic opera in two acts with music by Arthur Sullivan and libretto by W. S. Gilbert. The opera is a satire on the aesthetic movement of the 1870s and '80s in England and, more broadly, on fads, superficiality, vanity, hypocrisy and pretentiousness; it also satirises romantic love, rural simplicity and military bluster.

First performed at the Opera Comique, London, on 23 April 1881, Patience moved to the 1,292-seat Savoy Theatre on 10 October 1881, where it was the first theatrical production in the world to be lit entirely by electric light. Henceforth, the Gilbert and Sullivan comic operas would be known as the Savoy Operas, and both fans and performers of Gilbert and Sullivan would come to be known as "Savoyards."

Patience was the sixth operatic collaboration of fourteen between Gilbert and Sullivan. It ran for a total of 578 performances, which was seven more than the authors' earlier work, H.M.S. Pinafore, and the second longest run of any work of musical theatre up to that time, after the operetta Les Cloches de Corneville.

The opera is a satire on the aesthetic movement of the 1870s and '80s in England, part of the 19th-century European movement that emphasised aesthetic values over moral or social themes in literature, fine art, the decorative arts, and interior design. Called "Art for Art's Sake", the movement valued its ideals of beauty above any pragmatic concerns. Although the output of poets, painters and designers was prolific, some argued that the movement's art, poetry and fashion was empty and self-indulgent. That the movement was so popular and also so easy to ridicule as a meaningless fad helped make Patience a big hit. The same factors made a hit out of The Colonel, a play by F. C. Burnand based partly on the satiric cartoons of George du Maurier in Punch magazine. The Colonel beat Patience to the stage by several weeks, but Patience outran Burnand's play. According to Burnand's 1904 memoir, Sullivan's friend the composer Frederic Clay leaked to Burnand the information that Gilbert and Sullivan were working on an "æsthetic subject", and so Burnand raced to produce The Colonel before Patience opened. Modern productions of Patience have sometimes updated the setting of the opera to an analogous era such as the hippie 1960s, making a flower-child poet the rival of a beat poet.

The two poets in the opera are given to reciting their own verses aloud, principally to the admiring chorus of rapturous maidens. The style of poetry Bunthorne declaims strongly contrasts with Grosvenor's. The former's, emphatic and obscure, bears a marked resemblance to Swinburne's poetry in its structure, style and heavy use of alliteration. The latter's "idyllic" poetry, simpler and pastoral, echoes elements of Coventry Patmore and William Morris. Gilbert scholar Andrew Crowther comments, "Bunthorne was the creature of Gilbert's brain, not just a caricature of particular Aesthetes, but an original character in his own right." The makeup and costume adopted by the first Bunthorne, George Grossmith, used Swinburne's velvet jacket, the painter James McNeill Whistler's hairstyle and monocle, and knee-breeches like those worn by Oscar Wilde and others.

According to Gilbert's biographer Edith Browne, the title character, Patience, was made up and costumed to resemble the subject of a Luke Fildes painting. Patience was not the first satire of the aesthetic movement played by Richard D'Oyly Carte's company at the Opera Comique. Grossmith himself had written a sketch in 1876 called Cups and Saucers that was revived as a companion piece to H.M.S. Pinafore in 1878, which was a satire of the blue pottery craze.

A popular misconception holds that the central character of Bunthorne, a "Fleshly Poet," was intended to satirise Oscar Wilde, but this identification is retrospective. According to some authorities, Bunthorne is inspired partly by the poets Algernon Charles Swinburne and Dante Gabriel Rossetti, who were considerably more famous than Wilde in early 1881 before Wilde published his first volume of poetry. Rossetti had been attacked for immorality by Robert Buchanan (under the pseudonym "Thomas Maitland") in an article called "The Fleshly School of Poetry", published in The Contemporary Review for October 1871, a decade before Patience. Nonetheless, Wilde's biographer Richard Ellmann suggests that Wilde is a partial model for both Bunthorne and his rival Grosvenor. Carte, the producer of Patience, was also Wilde's booking manager in 1881 as the poet's popularity took off. In 1882, after the New York production of Patience opened, Carte sent Wilde on a yearlong US lecture tour, with his knee breeches, long hair and other idiosyncratic styling, to discuss poetry and the English aesthetic movement, intending to help popularise the show's American touring productions.

Although a satire of the aesthetic movement is dated today, fads and hero-worship are evergreen, and "Gilbert's pen was rarely sharper than when he invented Reginald Bunthorne". Gilbert originally conceived Patience as a tale of rivalry between two curates and of the doting women who attended upon them. The plot and even some of the dialogue were lifted straight out of Gilbert's Bab Ballad "The Rival Curates". While writing the libretto, however, Gilbert took note of the criticism he had received for his very mild satire of a clergyman in The Sorcerer, and looked about for an alternative pair of rivals. Some remnants of the Bab Ballad version do survive in the final text of Patience. Lady Jane advises Bunthorne to tell Grosvenor: "Your style is much too sanctified – your cut is too canonical!" Later, Grosvenor agrees to change his lifestyle by saying, "I do it on compulsion!" – the very words used by the Reverend Hopley Porter in the Bab Ballad. Gilbert's selection of aesthetic poet rivals proved to be a fertile subject for topsy-turvy treatment. He both mocks and joins in Buchanan's criticism of what the latter calls the poetic "affectations" of the "fleshly school" – their use of archaic terminology, archaic rhymes, the refrain, and especially their "habit of accenting the last syllable in words which in ordinary speech are accented on the penultimate." All of these poetic devices or "mediaevalism's affectations", as Bunthorne calls them, are parodied in Patience. For example, accenting the last syllable of "lily" and rhyming it with "die" parodies two of these devices at once.
