This book brings into dialogue two of the twentieth century's most famous artists: Marcel Duchamp (1887-1968), the father of conceptual art, and Salvador Dali (1904-1989), virtuoso painter of fabulous visions. Although at first glance they might appear polar opposites, the two men were united from their meeting in the 1930's by a firm friendship, rooted in a unique combination of originality, humor and scepticism. A fascinating series of texts and images explores their shared interest in science, optics, sex, and myth, their games with identity and their occasional collaborations, drawing on previously unpublished photographs, letters and ephemera as well as such masterpieces as 'The Bride Stripped Bare by Her Bachelors', 'Even', and 'Christ of St. John of the Cross.' Hardcover, 207 pages, Published by the Royal Academy of Arts and The Dali Museum, St. Petersburg, FL.
