A Companion to Geoffrey of Monmouth brings together scholars from a range of disciplines to provide an updated scholarly introduction to all aspects of his work. Arguably the most influential secular writer of medieval Britain, Geoffrey (d. 1154) popularized Arthurian literature and left an indelible mark on European romance, history, and genealogy. Despite this outsized influence, Geoffrey's own life, background, and motivations are little understood. The volume situates his life and works within their immediate historical context, and frames them within current critical discussion across the humanities. By necessity, this volume concentrates primarily on Geoffrey's own life and times, with the reception of his works covered by a series of short encyclopaedic overviews, organized by language, that serve as guides to further reading. Contributors are Jean Blacker, Elizabeth Bryan, Thomas H. Crofts, Sian Echard, Fabrizio De Falco, Michael Faletra, Ben Guy, Santiago Gutierrez Garci a, Nahir I. Otano Gracia, Paloma Gracia, Georgia Henley, David F. Johnson, Owain Wyn Jones, Maud Burnett McInerney, Francoise Le Saux, Barry Lewis, Coral Lumbley, Simon Meecham-Jones, Paul Russell, Victoria Shirley, Joshua Byron Smith, Jaakko Tahkokallio, Helene Tetrel, Rebecca Thomas, Fiona Tolhurst.

Why would the sprawling thirteenth-century French prose Lancelot-Grail Cycle have been attributed to Walter Map, a twelfth-century writer from the Anglo-Welsh borderlands known for his stinging satire, religious skepticism, ghost stories, and irrepressible wit? And why, though the attribution is spurious, is it not, in some ways, implausible? Joshua Byron Smith sets out to answer these and other questions in the first English-language monograph on Walter Map—and in so doing, he offers a new explanation for how narratives about the pre-Saxon inhabitants of Britain, including King Arthur and his knights, first circulated in England. Smith contends that it was inventive clerics like Walter, and not traveling minstrels or professional translators, who popularized these stories. Smith examines Walter's only surviving work, the De nugis curialium, to demonstrate that it is not the disheveled text that scholars have imagined but rather five separate works in various stages of completion. This in turn provides new evidence to support his larger contention, that ecclesiastical networks of textual exchange played a major role in exporting Welsh literary material into England. Medieval readers incorrectly envisioned Walter withdrawing ancient Latin documents about the Holy Grail from a monastery and compiling them in order to compose the Lancelot-Grail Cycle. In this detail they were wrong, Smith acknowledges, but a model of literary transmission that is not vernacular and popular but Latinate and ecclesiastical demands our serious consideration.
