Today serial imagery dominates all forms of visual media, from advertising to conceptual sculpture. In this innovative project, the authors show that the phenomenon of repetition appears as a radical element in early modern painting, long before its embrace by twentieth-century high modernism.In works by Ingres, Delaroche, Gerome, Corot, Millet, Monet, Cezanne, Degas, and Matisse, the reader can compare closely-related versions of some of the most familiar imagery of the 19th and early 20th centuries. By making multiples of closely related subject matter in their paintings, the authors argue, these painters challenged an aesthetic based on the notion of an inimitable, unique masterpiece.Through beautiful illustrations and essays by leading scholars, this book ultimately shows how the nineteenth-century invention of photography and film - with their intrinsic attribute of repetition - did not diminish the traditional medium of painting but rather propelled it in new directions.
