"_Acta Sanctorum Martyrum orientalium et occidentalium editore Stephano Evodio Assemano, que textum Chaldaicum recensuit, notis vocalibus animavit, Latine vertit, et annotationibus illustravit_." It is to be observed, that the eastern and western martyrs mentioned in this place, are not the martyrs of the eastern of Greek church, and the martyrs of the Latin or western church, in which sense the words eastern and western are generally used by ecclesiastical writers. By the eastern martyrs, Assemani denotes the martyrs who suffered in the countries which extend from the eastern bank of the Euphrates, over Mesopotamia and Chaldea to the Tigris and the parts beyond it; by the western, he denotes the martyrs who suffered in Syria, Palestine, and Egypt. Stephen Assemani was the nephew of Joseph Assemani, whose Kalendaria will be mentioned in another place. Joseph was first praefect of the Vatican library; Stephen was archbishop of Apamea; both of them were Maronite monks, and sent into the east by pope Clement XII. to purchase manuscripts. IX. 3. It was the pious custom of the early Christians to celebrate yearly the memory of the martyrs, on the days on which they suffered. On that day the martyr was considered to be born to a life of glory and immortality, and, with respect to that second life, it was called the day of his birth. The different churches, therefore, were careful to preserve an exact account of the particular days on which the martyrs obtained the crown of martyrdom. The book which contained this account was called a _Calendar_. At first the calendar contained the mention of the martyrs only; but, in the course of time, the confessors, or those who, without arriving at the glory of martyrdom, had confessed their faith in Christ by their heroic virtues, were admitted to the same honor. The calendars were preserved in the churches; a calendar of the Church of Rome was published by Boucher; another by Leo Alatius; a third by Joannes Fronto, chancellor of Paris, and canon regular of the church of St. Genevieve at Paris. A most ancient calendar of the church of Carthage was published by Mabillon. But under this head no publication is more respectable than Joseph Assemani's _Kalendaria Ecclesiae universae notis illustrata._ {023}
