Contributing to the current lively discussion of collaboration in French letters, this collection raises fundamental questions about the limits and definition of authorship in the context of the nineteenth century's explosion of collaborative ventures. While the model of the stable single author that prevailed during the Romantic period dominates the beginning of the century, the authority of the speaking subject is increasingly in crisis through the century's political and social upheavals. Chapters consider the breakdown of authorial presence across different constructions of authorship, including the numerous cenacles of the Romantic period; collaborative ventures in poetry through the practice of the "Tombeaux" and as seen in the Album zutique; the interplay of text and image through illustrations for literary works; the collective ventures of literary journals; and multi-author prose works by authors such as the Goncourt brothers and Erckmann-Chatrian. Interdisciplinary in scope, these essays form a cohesive investigation of collaboration that extends beyond literature to include journalism and the relationships and tensions between literature and the arts. The volume will interest scholars of nineteenth-century French literature, and more generally, any scholar interested in what's at stake in redefining the role of the French author.
