Computus fragment, containing excerpts from the Calculus of Victorius of Acquitaine and some Argumenta attributed to Dionysius Exiguus on the determination of Easter. It has been suggested that it originally belonged with another fragment, now in Milan, Biblioteca Ambrosiana, MS L 22 sup (ff. 146-147), and a flyleaf in Nancy, Bibliothèque municipale, MS 317 (356).

Dionysius Exiguus composed the earliest known computistical formulary written in Latin in 525. However, this formulary has not survived in its original form. The editors of Dionysius’ computistical writings, Wilhelm Jan and Bruno Krusch, published a corpus of 16 argumenta from a single manuscript, namely MS Oxford, Bodleian Library, Digby 63 under Dionysius’ name, since this was the only manuscript known to them that preserved the original 525 dating. Some of these 16 argumenta, however, contain dating clauses as late as 675, which immediately cast doubt on their ascription to Dionysius. In fact, the 16 argumenta edited by Jan and Krusch should more precisely be defined as a computistical formulary of 675, to be termed the Computus Digbaeanus of 675, which includes the original Dionysiac argumenta. This article, then, reconstructs the original Dionysiac corpus on the basis of new manuscript evidence. Moreover, the different stages of interpolations and additions that eventually led to the composition of the Computus Digbaeanus are analyzed, and with this the development of computistical formularies written in Latin in the 150 years from 525 to 675.

The Earlier Latin Manuscripts Project is a database of manuscripts written in Latin before the year 800 based on the work of E. A. Lowe and his assistants published in Codices Latini Antiquiores. The work for this project was conducted in the Department of Classics and the Moore Institute of the National University of Ireland Galway. Funding for its completion was contributed by both the Moore Institute and the School of Languages, Literatures, and Cultures. [...] Data from the database can be accessed in 3 ways, each subject to the license above: # Via the web front-end, accessible using the menu above; # By downloading a .csv file containing some or all of the data. This option is presented at the top of the catalogue page where you can filter and refine the data you would like to download; # By accessing the data via a JSON API (Application Programming Interface). Documentation on accessing data using this method is provided in the Technical Overview Section.
