This volume publishes and describes 157 papal documents, mostly deriving from the archives of religious houses (above all Cistercian), which survive in the original in the Haupsstaatsarchiv in Dresden. As the editor explains in the introduction, it is inspired largely by two existing projects: the Regesta Pontificum Romanorum of Paul Kehr, which has the aim of publishing every papal document dating from before the pontificate of Innocent iii (1198), and the censimento of original papal documents of the years 1198–1417 proposed by Franco Bartoloni. However, unlike both these projects, it is printing all the documents in full. This volume is said to be the first of three concerning original documents in the Dresden archives, and these are in turn part of a series of at least nine volumes of papal documents concerning Saxony, covering also copies of papal documents, original papalia in other Saxon archives, papal documents concerning Saxony surviving outside the region (including in the Vatican Archives), and documents issued by cardinals and papal office-holders. It is to be hoped that editorial energies and institutional resources will be sufficient to bring this noble and amibitious programme to a successful conclusion. An admirable start has been made by Tom Graber, the editor of the first volume. In the transcriptions of the documents he seems to have attained the highest standards of accuracy, and he has shown considerable ingenuity in reconstructing documents now destroyed or in poor condition. The greatest care has been taken in describing the external features of the letters including the chancery marks (see, for instance, the long annotation concerning the appointment of judges delegate in the audientia litterarum contradictarum on the dorse of no. 129). Graber's commentary on the documents is detailed and well-informed, with comprehensive references to the secondary literature. He is able to address many subtle questions of diplomatic. On occasion the discussion is perhaps more detailed and discursive than is strictly necessary, but it is difficult to quibble when there are so many instructive asides; for example, on p. 13 n. 5 about the different methods of calculating the beginning of the year. The five appendices list the chancery marks which appear on the documents, the first and fourth of them giving the names and identifications of the scribes and proctors respectively. The volume concludes with eight indices. Among these there is a welcome innovation in the form of a Verzeichnis der Siegel, a classification of documents’ leaden bullae.
