In the period between the Second World War and the present, there has been an extraordinary rise in the production of medievalist fantasy literature and film. This has been accompanied by the revival, performance and invention of medieval music. In this enterprise modern fantasies of the Middle Ages have exercised great influence. Fantasies of music in nostalgic medievalism shows how music, medievalism and nostalgia have been woven together in the fantasies of writers and readers, musicians, musicologists, directors and listeners, film-makers and film-goers. This book studies the ways in which three fields of creative activity inspired by the medieval – musical performance, literature, cinema and their reception – have worked together to produce and sustain, for some, the fantasy of a long-lost, long-mourned paradisal home.
