 (De divinis Lectionibus, c. xxiii), though by birth a Scythian, he was in character a true Roman and thorough Catholic, most learned in both tongues; by which he meant Greek and Latin; and an accomplished Scripturist. He translated standard works from Greek into Latin, principally the "Life of St. Pachomius", the "Instruction of St. Proclus of Constantinople" for the Armenians, the "De opificio hominis" of St. Gregory of Nyssa, and the history of the discovery of the head of St. John the Baptist. The translation of St. Cyril of Alexandria's synodical letter against Nestorius, and some other works long attributed to Dionysius are now acknowledged to be earlier and are assigned to Marius Mercator.

Of great importance were the contributions of Dionysius to the science of canon law, the first beginnings of which in Western Christendom were due to him. His Collectio Dionysiana embraces (1) a collection of synodal decrees, of which he has left two editions: (a) Codex canonum Ecclesić Universć. This contains canons of Oriental synods and councils only in Greek and Latin, including those of the four ścumenical councils from Nicća (325) to Chalcedon (451). (b) Codex canonum ecclesiasticarum. This is in Latin only; its contents agree generally with the other, but the Council of Ephesus (431) is omitted, while the so-called "Canons of the Apostles" and those of Sardica are included, as well as 138 canons of the African Council of Carthage (419). (c) Of another bilingual version of Greek canons, undertaken at the instance of Pope Hormisdas, only the preface has been preserved. (2) A collection of papal Constitutions (Collectio decretorum Pontificum Romanorum) from Siricius to Anastasius II (384-498).

) because, as he explained to Petronius, he did not wish to continue the memory of a tyrant who persecuted Christians. The only reason he gave for beginning his new 95-year table with the year 532 was that six years were still left in the Cyrillian table after the year during which he wrote. For the latter year he only stated that it was 525 years after the Incarnation of Christ, without stating when the latter event occurred in any other calendar. He did not realize that the dates of the Alexandrian Easter repeated after 532 years, despite his apparent knowledge of the Victorian 532-year 'cycle', indicating only that Easter did not repeat after 95 years. He knew that Victorian Easters did not agree with Alexandrian Easters, thus he no doubt assumed that they had no bearing on any Alexandrian cycle. Furthermore, he obviously did not realize that simply multiplying 19 by 4 by 7 (decennovenal cycle x cycle of leap years x days in a week) fixed the Alexandrian cycle at 532 years, otherwise he would have stated such a simple fact.

No evidence exists that the Church of Rome accepted the Dionysian tables until the tenth century, although it is possible that they were accepted sometime during the sixth century. Most of the British Church accepted them after the Synod of Whitby

). Because the anniversary of the Incarnation was 25 March, which was near Easter, a year that was 525 years "since the Incarnation" implied that 525 whole years were completed near that Easter. Consequently one year since the Incarnation would have meant 25 March 1, meaning that Dionysius placed the Incarnation on 25 March 1 BC. Because the birth of Jesus was nine calendar months later, Dionysius implied, but never stated, that Jesus was born 25 December 1 BC. Only one scholar, Georges Declerq (Declerq, 2002), thinks that Dionysius placed the Incarnation and Nativity in AD 1, basing his conclusion on the structure of Dionysius's Easter tables. In either case, Dionysius ignored his predecessors, who usually placed the Nativity in the year we now label 2 BC. Kepler

 in 325 sanctioned his method of dating Easter, the surviving documents are ambiguous. A canon of the council implied that the Roman and Alexandrian methods were the same even though they were not, whereas a delegate from Alexandria stated in a letter to his brethren that their method was supported by the council. In either case, Dionysius' method had actually been used by the Church of Alexandria (but not by the Church of Rome) at least as early as 311, and probably began during the first decade of the fourth century, its dates naturally being given in the Alexandrian calendar. Thus Dionysius did not develop a new method of dating Easter. The most that he may have done was convert its arguments from the Alexandrian calendar into the Julian calendar
