Towards 500 a Scythian monk, known as Dionysius Exiguus, who had come to Rome after the death of Pope Gelasius (496), and who was well skilled in both Latin and Greek, undertook to bring out a more exact translation of the canons of the Greek councils. In a second effort he collected papal decretals from Siricius (384-89) to Anastasius II (496-98), inclusive, anterior therefore, to Pope Symmachus (514-23). By order of Pope Hormisdas (514-23), Dionysius made a third collection, in which he included the original text of all the canons of the Greek councils, together with a Latin version of the same; but the preface alone has survived. Finally, he combined the first and second in one collection, which thus united the canons of the councils and the papal decretals; it is in this shape that the work of Dionysius has reached us. This collection opens with a table or list of titles, each of which is afterwards repeated before the respective canons; then come the first fifty canons of the Apostles, the canons of the Greek councils, the canons of Carthage (419), and the canons of preceding African synods under Aurelius, which had been read and inserted in the Council of Carthage. This first part of the collection is closed by a letter of Pope Boniface I, read at the same council, letters of Cyril of Alexandria and Atticus of Constantinople to the African Fathers, and a letter of Pope Celestine I. The second part of the collection opens likewise with a preface, in the shape of a letter to the priest Julian, and a table of titles; then follow one decretal of Siricius, twenty-one of Innocent I, one of Zozimus, four of Boniface I, three of Celestine I, seven of pope Leo I, one of Gelasius I and one of Anastasius II. The additions met with in Voel and Justel are taken from inferior manuscripts.
