"multiplies what he cannot unify ... It is his way of giving and vivifying". In the 1956 Buddy Holly single "Modern Don Juan", the singer gains a reputation for being like the libertine in his pursuit of a romantic relationship. Swedish film director Ingmar Bergman wrote and directed a comic sequel in 1960 titled The Devil's Eye in which Don Juan, accompanied by his servant, is sent from Hell to contemporary Sweden to seduce a young woman before her marriage. Anthony Powell in his 1960 novel Casanova's Chinese Restaurant contrasts Don Juan, who "merely liked power" and "obviously did not know what sensuality was", with Casanova, who "undoubtedly had his sensuous moments". Stefan Zweig observes the same difference between both characters in his biography of "Casanova". in 1970 Faroese author William heinesen released his short story , in which a character embodying Don Juan is washed up on the Faroe Islands in Torshavn and begins to seduce the women of that town. In the 1910 French novel The Phantom of the Opera by Gaston Leroux, the titular character (also known as Erik) had spent much of his life writing an opera, Don Juan Triumphant, refusing to play it for Christine Daaé and telling her that it was unlike any music she ever heard and that when it was complete, he would die with it, never sharing it with mankind. Following the unmasking scene, Erik refers to himself as Don Juan as he confronts Christine, verbally and physically abusing her as he uses her hands to gouge his face, exclaiming "When a woman has seen me – as you have – she becomes mine ... I'm a real Don Juan ... Look at me! I'm Don Juan Triumphant!" Don Juan is also a plot point in Susan Kay's novel Phantom, which expands on Gaston Leroux's novel The Phantom of the Opera. The titular character was referred to as "Don Juan" in his childhood, a nickname given to him by Javert, a man who exploited Erik as a child. Later in life, he began writing Don Juan Triumphant, spending decades on the piece, which Christine Daaé heard after hiding in her room after removing Erik's mask. In the 1986 Broadway musical adaptation of Gaston Leroux's 1910 The Phantom of the Opera, the character of the Phantom writes an opera based on the legend of Don Juan called Don Juan Triumphant.
