This book explores the life and fiction of the French decadent writer Rachilde (pen name of Marguerite Eymery), using her as a case study to examine the impact late nineteenth-century theories about female hysteria, medical hypnotism, mediums, and spiritualism had on the female creative psyche. Rachilde was especially vulnerable as she suffered hysterical attacks, witnessed a hypnotism craze in France, and was the only child in a family of table-tapping spiritualists. After a biographical first section, chapters examine how hysteria, hypnotism, and spiritualism penetrated the sociocultural fabric of France in the period between 1870-1900, and how Rachilde’s novels represented, unconsciously absorbed, or at other times mocked those discourses. Because she was prosecuted for the 'obscenity' of her first major success, Monsieur Venus , this study also situates her writing comparatively within the production of other late-century pornographers. A final chapter analyzes how Rachilde’s work confronts the disabling doctrines of her time and how, out of them, she constructs a unique and productive writing stance.
