A useful document, especially for saints’ days, is a lectionary of the orthodox Syrians contained in the codex xix. of the Vatican Library. It was written in the monastery of Mar Mussa at Antioch in 1030, and contains in the first section the lections for the ecclesiastical year, in the second, those for saints’ days, beginning with the 1st September as New Year’s Day. In it are given the martyrs of the Iconoclastic controversy, several orthodox patriarchs of Constantinople, Nicephorus († 2nd June 828) being the last; then come many names from the old Testament, and many feasts of apostles, the Catenæ Petri on the 16th January being one of them, four feasts of St John the Baptist, and six of our Lady. There are no Roman or Western saints with the exception of St Lawrence. This document has been published by Count F. Miniscalchi-Errizzo under the title Evangeliarium Hierosolymitanum (2 vols. 4to, Verona, 1682).

In using documents of this kind for purposes of historical investigation, as for instance in order to determine the day on which a historical personage died, the appeal must always be to the local sources. In the case of saints belonging to the Western Church no importance must be attached to the fact that the Easterns may have transferred them to a different day, and vice versâ, as, for example, in the case of St Ignatius of Antioch. Where the day is given in some local source, otherwise deserving of credit, we can be then certain that it is correct. This must be done with regard to SS. Peter and Paul, for whom the local sources give invariably the 29th June, while foreign calendars give other dates, as we find is the case with Polemius, Silvius, and the Arian martyrology. The compilers of these calendars wished to celebrate the Princes of the Apostles, but, being ignorant of the actual day of their death, placed them on any day that seemed suitable. Finally, at a later date the correct date came to the knowledge of foreign churches, and found its way into their calendars.

9. The Kalendarium Marmoreum of Naples

In the ninth century, a time of great activity in matters relating to hagiography, the Church of Naples undertook a revision of its calendar, which exhibits noteworthy peculiarities.

First of all, nearly every day of the year is provided with the name of a saint, which indicates considerable care and study. This result was achieved by following the Eastern custom of admitting Old Testament personages, although not to the same extent. The grounds on which the selection was made cannot be discovered, for we have Abraham on the 9th October, Isaac on the 17th March, Eliseus on the 28th November, Daniel on the 17th December, Zacharias on the 13th May, while other important personages, such as Isaias, etc., are omitted. We are also reminded of eastern usage by the commemoration of the council of Ephesus on the 4th August, and other traces of eastern influence are noticeable in the admission of a few bishops of Constantinople, such as Metrophanes, and also of the names of Constantine (without Helena) on the 21st May, and Theodosius on the 10th November. With regard to Metrophanes, the compiler is guilty of a remarkable oversight; he has placed him once on the right day (the 4th June), without his title, and again on the 4th January with his title, “Patr. Const.” The confusion between the 4th of June and the 4th of January might easily escape a transcriber, and must have already existed in the source which the compiler used. In order not to omit any name the compiler preferred to enter the same name twice, once with, and once without, its proper title.

This reminds us that St Mark also occurs twice, on the 25th April and the 17th May. St Philip is united to St James on the 1st May (a trace of Roman influence), and is found again alone on the 14th November. St Silvester comes on the 31st December and a Depositio Silvestri P.P., on the 2nd January; a Jacobus Ap. and Mattheus on unusual dates, the 15th and 16th November, other Apostles are on more usual dates, e.g. St Jude is commemorated on the 21st May. St Bartholomew’s day (the 25th August) is given wrongly as Nat. Pass., being in reality the day of his translation. The names of Apostles and their disciples are very numerous.

With regard to the worship of the Holy Cross, both days occur (i.e. the 3rd May and 14th September), with the title now in use, although formerly, the feast of the 3rd May was alone observed in the West, and that of the 14th September in the East. The reason for this circumstance has been already given in this book. Bishops of Naples naturally appear frequently; e.g. Maro (15th June) belongs to the third century, others belong to the period from the sixth to the eighth century, such as Redux on the 27th March († 584), Agnellus on the 9th January († 691), Adeodatus on the 1st October († 671), Fortunatus on the 14th June († 600 circ.), Paulus the elder on the 3rd March († 760). The last to be named is probably Paul the younger on the 17th February († 820).[803] Paul III. of Constantinople cannot be intended here, for his day is the 30th August. We may add that the feast of All Saints had not yet been admitted, a circumstance which throws light on the probable date when this calendar was drawn up. Special importance attaches to this calendar on account of its intermediate position between the calendars of the Eastern and Western Churches.

It was discovered in 1742 in S. Giovanni Maggiore and edited incorrectly, according to Mai, by Marinius, correctly by Mazzochius (Naples, 1744). The most recent edition is by A. Mai himself.[804]
