The Familiar Enemy examines the linguistic, literary, and cultural identities of England and France during the Hundred Years War. It explores works by Deschamps, Charles d'Orléans, and Gower, as well as Chaucer who, the book argues, must be resituated within the context of the multilingual cultural geography of medieval Europe.
