The author, well-known as an outstanding Byzantine canonist, was Archbishop of Ohrid (approx. 1216-1236) and practically assumed the position of a Patriarch. The Corpus of the Pone-mata diaphora (personal and official letters, expert testimonies and verdicts and proceedings of the Ohrid Synodal Court) is his major work. It pro--vides complex source material of major importance in two ways: historically because of the detailed information on the political and ecclesiastical history of South-Eastern Europe at the time of radical change around 1204; legally because texts (let alone corpora) dealing with the practice of ecclesiastical jurisdiction in Byzantium are few and far between.
This new edition replaces the older, non-critical, edition by Cardinal Pitras from 1891.
