The fragment of Felix in the Bobbio Computus shows a recension independent from that known from the manuscripts Digby 63, 67r–v and 70v–71r, and Ambrosiana H 150 inf., 50v. It is inserted in the Etymologiae of Isidore (VI 17), but neither the arrangement of Isidore’s work nor the cycles in Etymologiae VI 17 resemble the standard edition. They may reflect the early organization of the work in fifteen books as arranged by Braulio, rather than the later division in twenty books attributed to Theodulf of Orléans.
The 95-year cycle also shows independent features. Though inserted in the Etymologiae and thus presumably Isidorian, it is quite unlike other known cycles from AD 627 to 721 (Ambrosiana L 99 sup., Digby 63). But there are also discrepancies between the contemporary cycles from 798 to 892 (Ambrosiana H 150 inf., 93v–98r) and those in the Felix/Isidore section of the same codex. Without further study we cannot determine when the texts of Isidore and Felix became known at Bobbio, but the evidence, such as it is, suggests that the Bobbio computist was not merely copying, but elaborating this material, and this fact may be indicative of a school of computistics at Bobbio in the seventh and eighth century.
Latin antiphonary. A contemporary colophon to the final hymn states that the manuscript was written at Bangor when Colmán was its abbot (680-691). The manuscript was brought to the continent and kept in the Bobbio library.

9th-century manuscript of Bobbio provenance containing a copy of the Ars Ambrosiana, which is a commentary on the second book of Donatus’ Ars maior. On f. 8r, there is an Old Irish gloss embedded within the text, which seems to have been copied from the exemplar of the manuscript.
