This book focuses on avant-garde literature and art in Europe and America during the first quarter of the twentieth century. It examines five movements that shaped our response to the demands of the modern age and contributed to the creation of a modern sensibility: Cubism, Futurism, the Metaphysical School, Dada, and Surrealism. Each of these arose in response to recent scientific, technological, and/or philosophical developments that drastically affected modern civilization. In turn, each was responsible for a major paradigm shift that altered the way in which we view—and respond to—the world around us. The final chapter is comparative in nature and studies the role of the mannequin in literature and art during the same period.
