'Christof Rolker provides for the first time a truly comprehensive examination of the letters' [of Ivo of Chartres] transmission. This, however, is only one of this outstanding work's achievements. For Rolker also re-assesses the state of canon law and theology in northern France at the beginning of the twelfth century and Ivo's role in the creation of a distinct canonistic jurisprudence … I recommend this volume to any student of medieval life around 1100.'
