The series Sylloge diplomatico-palaeographica (as subseries of the "Veroffentlichungen zur Byzanzforschung") was founded as a result of the scientific focus on Byzantine diplomatics and paleography at the Institute of Byzantine Studies of the AAS. It is intended to centralize studies and research on Byzantine documents; hence palaeographica is added intentionally, because every research on documents has to investigate the primary sources, therewith the paleography (and codicology) of the text transmitters. The volume contains research of the thematic focus on the Patriarchate of Constantinople and documents in connection with the chancellery of the Patriarch (in this case the 12th century with Ioannes Xth Kamateros, the 13th century with Manuel Ist Sarantenos and the 14th century with professions of faith of the Registrum Patriarchatus Constantinopolitani) as well as a basic study on the cartulary B of the John Prodrom monastery at Serrhai illustrating problems of modern text editions. The first issue of the sylloge is completed by an analysis of epigrams (a further scientific main focus of the institute) which are related to documents. Two articles result from projects, supported by the FWF (project nr. P19818-G02, P 19135-G02). German text.
