This major reference work is the fourth volume in the series'Arthurian Literature in the Middle Ages'. Its intention is to update the French and Occitan chapters in R.S. Loomis''Arthurian Literature in the Middle Ages: A Collaborative History'(Oxford, 1959) and to provide a volume which will serve the needs of students and scholars of Arthurian literature. The principal focus is the production, dissemination and evolution of Arthurian material in French and Occitan from the twelfth to the fifteenth century. Beginning with a substantial overview of Arthurian manuscripts, the volume covers writing in both verse (Wace, the Tristan legend, Chretien de Troyes and the Grail Continuations, Marie de France and the anonymous lays, the lesser known romances) and prose (the Vulgate Cycle, the prose Tristan, the Post-Vulgate Roman du Graal, etc.).
