Calendars

The calendars that I have used for this compilation come from the Patriarchates of Rome & Constantinople.

Rome

The Martyrology of Usuard = Jacques Dubois, ed., Le Martyrologe d'Usuard: Texte et Commentaire (Brussels: Bollandist Society, 1965). Usuard was a monk who produced a Martyrology during the 9th century. Dubois used the 9th century MS. "Bibliotheque Nationale de Paris, Manuscript Latin 13745" which is available online in a scanned copy here.
The Martyrology of Notker = Jacques Paul Migne, ed., Patrologia Latina, Volume 131 (1853). Just like Usuard, Notker "The Stammerer" was a monk who produced a Martyrology around the year 900. A single MS. copy of the Martyrology survives (St. Gallen, Stiftsbibliothek, Cod. Sang. 456), written around 900─950, and which Migne included in his monumental Patrologia Latina. The MS. can be found online in a scanned copy here.
The Martyrology of Ado = A MS. (St. Gallen, Stifrsbibliothek, Cod. Sang. 454) from 880─890 that is available in an online scanned copy here.
The Martyrology of Jerome = Marijana Vukovic, The Cult of Saints. This Martryology traditionally ascribed to Jerome are some of the oldest martyrologies that we have. The MSS. that I have used in this list are the following:

MS. BNF (Bibliotheque Nationale de France, Latine 10837) which is a MS. written by a scribe named Laurentius in the years 703─710 and is available in a scanned copy here.

MS. Bern (Burgerbibliothek, Bongars 289) which is a MS. written ca. 800 ─ ca. 866.

MS. Weissenburg (Herzog August Bibliothek, Weissenburg 81) which is a MS. written in the second half of the 8th century and available online in a scanned copy here.

Constantinople

The Typicon of the Great Church = Juan Mateos, ed. and tr., Le Typicon de la Grande Église, Volume 1 (Rome: 1962). The Typicon shows the church calendar used in the Hagia Sophia at the middle of the tenth century. It relies on two manuscripts:

Codex H (Holy Cross Monastery Codex 40) is dated by Mateos to the years 950-970, with 950-959 being the more probable. Venance Grumel however dates the ms. to the end of the tenth century, and believes it to be an edited copy of an earlier work. [Venance Grumel, 'Le Typicon de la Grande Église d'apres le Manuscrit de Sainte-Croix: Datation et Origine', Analecta Bollandia, 85 (1967), 45-57] Regardless the ms. certainly seems to be from the tenth century. This manuscript covers the entire year, with only a few days at the end of August absent.

Codex P (Patmos Codex 266) is dated from the second half of the ninth century to the first half of the tenth. This manuscript covers the entire year.

A Note on the Dating

The dates of the Patriarchs are taken from Venance Grumel, La Chronologie (Paris: 1958), pp. 430─433. Many of the early bishops are of indeterminable dates.
