"This is an extremely well-researched and well-presented study that is informed by meticulous textual analysis from the manuscripts...Yet this book goes even further in that Larson asks the reader to consider the development of both theological and legal thought in the second half of the twelfth century...a splendid achievement, and Larson is to be both thanked and congratulated on such a stimulating book." -American Historical Review "By focusing on a rather neglected part of Gratian's masterwork, Master of Penance illuminates the fascinating world of twelfth-century intellectual life from an unexpected angle and is a real contribution to our knowledge of Gratian, penance, and the intellectual life of the long twelfth century in general." -The Catholic Historical Review "A significant contribution to Gratian studies. It will appeal to scholars of canonical history and sacramental theology. It also makes an important segment of Gratian's work accessible to canonists who do not have the opportunity to work through the Decretum on their own." - The Jurist "This exciting, tightly-packed volume explores a neglected dimension of Gratian's educational background and intellectual accomplishments...It will be important for those at the graduate level and above working in twelfth-century canon law and theology." - Religious Studies Review
