texts by Jennifer Gough-Cooper and Jacques Caumont As the century draws to a close, it becomes increasingly clear how profoundly Marcel Duchamp influenced the trajectory of modem art. This remarkable book with its more than 1,300 illustrations covers 70 years of Duchamp's artistic production and traces his elusive personae across that same span. It documents his extraordinary achievements in painting and sculpture as well as his life-long involvement with chess, film, theater, and people - from intimate encounters to artistic liaisons. Marcel Duchampis designed as a double-faced publication: from one direction, entitled Works, it contains a catalogue reproducing Duchamp's paintings, sculptures, and miscellaneous objects (150 illustrated in color). From the other direction, entitled EphÉmÉrides, unfolds a day-by-day account of the artist's life, organized by astrological sign. The greater part of this detailed chronology relies upon unpublished materials. It is enriched by 1,200 documents and photographs, including a number of works by Duchamp that have never before been reproduced. Each section is printed on a different color paper. Sandwiched between these two sections is a concordance listing writings by and about Duchamp, a bibleography (letters sent by Duchamp), exhibition catalogues, a chronology of chess games, and a filmog­raphy. Pontus Hulten, Director of the Palazzo Grassi in Venice between 1985 and 1989, is the chief curator of the Duchamp exhibition in Venice. Jennifer Gough-Cooper and Jacques Caumont are Duchamp scholars who have devoted themselves exclusively to Duchamp studies for the past fifteen years.
