Medieval bishops' wills were complex and (sometimes) contested documents, caught between many competing interests. They had to conform to the different kinds of law under which bishops worked, they had to reflect the division between personal effects and the goods of the bishopric itself, and they had to respect the relations between bishops and their cathedral chapters, much of which was defined by local custom. In many cases wills could not be written as a matter of course, but depended on specific royal – and more rarely papal – licence, and were always menaced by the potential assertion of regalian right. The documents edited in this volume are therefore much more than just records of legacies; they are fundamental to any understanding of the legal and constitutional position of bishops in the Middle Ages, and especially their relationship to the rights claimed by kings. The volume is divided into three main parts. The first part is a substantial and comprehensive introduction which explains the legal and administrative framework within which wills were written and used, how wills were structured and written, and how probate and execution worked. It also points to the importance of these sources for political and legal history, and for understanding elite material culture. The second part is a catalogue of probate documentation from around 1200, when episcopal wills became more common, to 1413, from which point wills were copied into the Canterbury archiepiscopal registers. It is organised by diocese, and begins with a note of the specific circumstances and customs peculiar to each, such as the fees charged on the estates of bishops of St Asaph (p. 52), or claims that particular cathedral chapters might make on the goods of a deceased bishop. After that, each diocesan section is then split into subsections for each successive bishop, themselves divided into a classified list of texts or mentions of lost texts for licences to make wills, actual texts of wills, names of executors, the probate process and execution and, finally, other bequests. The third part consists of editions of those wills, codicils, correspondence about probate and execution, and inventories of goods which have not previously been edited, or which have not been edited fully. Beyond the three main sections, there is a glossary of words not contained in the usual dictionaries and wordlists – mostly terms denoting domestic items – and comprehensive indices of persons and places, of subjects and of books named in the texts. This is an important and useful volume in a number of ways. It makes available editions of texts which deserve wide use, provides an introduction which gives a rich context for reading them, and gives an overview of a range of documentation which has not hitherto been readily accessible as a coherent collection, for it survived dispersed among very many archives. It should be of great value in work on medieval bishops and on elite households in general.
