For many years teachers and students of crusading in the thirteenth century had to subsist on a meagre diet of translated material. There was the invaluable Penguin coupling of Villehardouin and Joinville, and a useful selection of texts translated by Louise and Jonathan Riley-Smith. And there was a translation of Oliver of Paderborn, supplemented by a handful of other Fifth Crusade texts, by Edward Peters. But that was about all. In the last few years this famine has been transformed into a feast thanks to the diligent efforts of practising historians who acknowledge the value of teaching through study of the sources. Alfred Andrea translated the most important sources for the Fourth Crusade, Peter Jackson gave us an excellent collection of translated sources for Louis ix's crusade to Egypt, while Christoph Maier both edited and translated a group of model crusade sermons. Malcolm Barber and Keith Bate published useful translations of texts about the Templars, and assorted letters sent from the East. Now we possess this vastly expanded version of the Peters collection. This volume possesses the great virtues of being comprehensive in scope and scrupulously edited. It contains seventy-three texts, ranging from Gregory vii's bull Audita tremendi, his anguished response to the battle of Hattin in 1187, to Muslim accounts of the fall of Acre in 1291. So the full trajectory of the loss of the Holy Land is covered. The editors give space to all of the major expeditions to the East from the Fourth Crusade to Louis ix's ventures and the planning in the 1270s. In addition, there is coverage of Las Navas de Tolosa, the ‘popular’ crusades of the pueri (1212) and pastoureaux (1251), the crusades against the Mongols, and crusading against the Staufen and Aragonese. The icing on the cake is a small but revealing group of texts about the problems that were faced by individual crusaders. Naturally there is overlap and omission. But one has to admire the way in which difficult choices have been made, and the editing is first class, with scholarly but accessible commentary and clear bibliographic signposting. This collection is a really welcome contribution to the literature. It will greatly facilitate the teaching of the subject, illuminating not just the diversification, appeal and vitality of crusading in this period, but also the spectrum of tensions and problems which made it impossible for the West to retain its grip on the Holy Land.
