In response to this skepticism, Max Ernst embraced automatism and developed a new technique, which he called frottage , in an attempt to satisfy Breton's call for automatic activity, and in 1926, a collection of thirty-four frottages was published under the title Histoire Naturelle. This thesis provides a comprehensive analysis of Histoire Naturelle by situating it in the theoretical context of Surrealist automatism and addresses the means by which Ernst incorporated found objects from the natural world into the semi-automatic production of his frottages. All previous scholarship on the subject is consolidated and critically examined, and the development of frottage is traced from its earliest manifestations to its long-lasting influences.en-USErnst, Max, 1891-1976 -- Criticism and interpretationSurrealism -- GermanyThesis
