Polemius Silvius
Polemius Silvius ("fl." 5th century) was the author of an annotated Julian calendar that attempted to integrate the traditional Roman festival cycle with the new Christian holy days. His calendar, also referred to as a laterculus or "fasti", dates to around 448–449. He was active in southeastern Gaul. Background. Polemius was among the Christian cultural elite working within the imperial bureaucracy in Gaul under Valentinian III. He was a friend of Hilarius of Arles. The "Gallic Chronicle of 452", year 438, calls him "mentally disturbed." Polemius was assigned to Eucherius, bishop of Lyon (ancient Lugdunum), and produced the  calendar for him. Because fixed Christian feasts were still few in number, Polemius faced the challenge of fulfilling the conventions of a traditional Roman calendar with named holidays while "disinfecting" it of the Imperial Roman and other festivals now regarded as "pagan." Although the Calendar of Filocalus in 354 had recorded the traditional religious holidays freely, by the time of Polemius the Christian state had begun to legislate against other religions and to divorce Rome's religious heritage from the culture and civic life of the Empire. Polemius, who had probably consulted the Calendar of Filocalus, filled gaps with meteorological  and seasonal markers, and the "Egyptian days," days considered unpropitious for new undertakings and for certain medical practices. Bede was among those who drew information from it. In Polemius's calendar, the word "ludi", "games" in classical Latin, means more specifically theatrical performances, while "circenses" is used for chariot races. His work provides significant examples of Gallo-Romance vocabulary, regional variations of the Latin language, and local survivals of Gaulish words. The calendar. The format used by Polemius for the most part followed the conventions of Roman calendars, with days arranged in parallel columns under the name of the month , and each day noted on a separate line. Column 1 numbers the days of the month. Column 2 identifies any special days, not only traditional Roman and Christian holidays, but also the birthdays of emperors, and days when consuls and praetors took office. Column 3 gives weather conditions; Columella's 1st-century treatise on agriculture may have influenced the inclusion of references to weather. Polemius also provided information from his own research, such as the birthdays of Cicero, Vergil, and a Faustina who was the divinized wife "(diva)" of an Antonine emperor. Because the Roman calendar had traditionally served a  didactic purpose, the "laterculus" of Polemius provided several other lists and tables under the month-by-month chronographic presentation: Lost portions are known only from the introductory synopsis. For each month, the calendar also presents the equivalent Hebrew, Egyptian, Athenian, and Greek names. List of Provinces. Polemius Silvius also wrote a list of Late Roman provinces, which Seeck appended to his edition of the Notitia Dignitatum. The list is famous because it names six provinces in Roman Britannia: the sixth is the dubious "Orcades provincia".
