This book traces the artistic trajectories of Djuna Barnes and Jane Bowles, examining their literary representations of the nomadic ethic pervading the twentieth-century expatriate movements in and out of America. The book argues that these authors contribute to the nomadic aesthetic of American modernism: its pastoral ideographies, (post)colonial ecologies, as well as regional and transcultural varieties. Mapping the pastoral moment in different temporalities and spaces (Barnes representing the 1920s expatriation in Europe while Bowles comments on the 1940s exodus to Mexico and North Africa), this book suggests that Barnes and Bowles counter the critical trend associating American modernity primarily with urban spaces, and instead locate the nomadic thrust of their times in the (post)colonial history of the American frontier.
