'Given the immense importance of those years between 1119 and 1124, Stroll's weighty survey of the achievements of the reign of Calixtus is to be welcomed... She has provided much food for further thought.' Constant J. Mews, BMR, 2006. The author deserves considerable thanks for the thoroughness of her research and for providing us with the first biography of Calixtus in more than a century. She demonstrates that this pontificate is not just merely interesting but essential to understand the problems confronting the papacy, not just in terms of church and state but also the fundamental divisions within the leadership of the church. Those who continue to study the reform papacy will certainly find this work useful. James M. Powell, Speculum
