The idyllic Cape Cod retreat of suffragists Verena Tarrant and Olive Chancellor in Henry James's The Bostonians (1886) is called Marmion, evoking what James considered the Quixotic idealism of such social reformers. In To the Lighthouse by Virginia Woolf, Mrs. Ramsey glances at her husband: Virginia Woolf, in a letter to Hugh Walpole on 12 September 1932, writes: John Cowper Powys described Walter Scott's romances as "by far the most powerful literary influence of my life". This can be seen particularly in his two historical novels, Porius: A Romance of the Dark Ages, set during the end of Roman rule in Britain, and Owen Glendower. In 1951, science-fiction author Isaac Asimov wrote Breeds There a Man...?, a short story with a title alluding vividly to Scott's The Lay of the Last Minstrel (1805). In Harper Lee's To Kill a Mockingbird (1960), the protagonist's brother is made to read Walter Scott's book Ivanhoe to the ailing Mrs. Henry Lafayette Dubose. In Mother Night (1961) by Kurt Vonnegut Jr., memoirist and playwright Howard W. Campbell Jr. prefaces his text with the six lines beginning "Breathes there the man..." In Knights of the Sea (2010) by Canadian author Paul Marlowe, there are several references to Marmion, as well as an inn named after Ivanhoe, and a fictitious Scott novel entitled The Beastmen of Glen Glammoch. The other arts Although Scott's own appreciation of music was basic, to say the least, he had a considerable influence on composers. Some 90 operas based to some extent on his poems and novels have been traced, the most celebrated being Rossini's La donna del lago (1819, based on The Lady of the Lake) and Donizetti's Lucia di Lammermoor (1835, based on The Bride of Lammermoor). Others include Donizetti's 1829 opera Il castello di Kenilworth based on Kenilworth, Georges Bizet's La jolie fille de Perth (1867, based on The Fair Maid of Perth), and Arthur Sullivan's Ivanhoe (1891). Many of Scott's songs were set to music by composers throughout the 19th century. Seven from The Lady of the Lake were set in German translations by Schubert, one of them being 'Ellens dritter Gesang' popularly known as 'Schubert's Ave Maria'''. Three lyrics, also in translation, appear from Beethoven in his Twenty-Five Scottish Songs, Op. 108. Other notable musical responses include three overtures: Waverley (1828) and Rob Roy (1831) by Berlioz, and The Land of the Mountain and the Flood
