A Companion to Geoffrey of Monmouth introduces Geoffrey’s oeuvre to first-time readers and provides a synthesis of current scholarship, all while offer-ing new readings of his work. This volume also seeks to bring Celtic studiesand Galfridian studies into closer dialogue, especially given the importanceof Wales to Geoffrey and his work. To that end, many of the essays are writtenby specialists in Welsh history and literature, whose voices have at times beenhard to discern in the general din of Galfridian scholarship. We have also askedcontributors to focus on all of Geoffrey’s work, and not merely the Arthuriansections. Geoffrey has been well-served by Arthurian scholarship, and we haveno desire to replicate many of the excellent recent studies in that field.7 Instead,we hope a holistic approach to his work will reveal subtleties often overlookedin scholarship that concentrates primarily on the Arthurian portions.
