For several years now, sigillography as an independent subject in the field of Byzantine studies, has received increasing attention from both Byzantine studies and related disciplines, because it is the only area still able to provide plenty of yet undiscovered material for research and study. The articles deal with all aspects of Byzantine sigillography: presentation of new finds, discussion of new methods, questions of the political and ecclesiastical administration of Byzantinum, prosopography, historical geography, and art historical and iconographical problems. In addition, the volumes contain a loosely arranged list of Byzantine seals, which have been published in essays and auction catalogues, thus enabling those from more obscure publications to be located and identified. Volume 9, currently in preparation, mainly contains lectures from the 8th International Symposium on Byzantine Sigillography held in October 2003, in Berlin. Besides the iconography of seals, much emphasis was placed on questions of Byzantine administration. Further, selected collections are presented, as well as a large number of new finds and new acquisitions.
