Vatican, Biblioteca Apostolica Vaticana, Vat. lat. 3791 is a late eleventh or early twelfth-century manuscript of 308 fols., plus eight later added folios (V^a-h), an extra ‘bis’ folio (CCXXXIII^bis) and eight folios beforehand (Ir-Vv), minus 37 removed (?) fols. (VII-XIII, XCII-CI, CXC-CXCIC, and CCXC-CCXCIX) in 1 col (252 x 165 mm (179 x 103 mm)). Its preliminary codicological composition reads as follows: 35-37 quires, (III + 2)⁸ + IV¹⁶ + 35 x IV³⁰⁸, quire signatures from I^V to XXXIIII³⁰², with quire signature II missing and quire 35 (XXXV) not numbered; the late medieval to early modern foliation numbering in Latin numerals is interpolated and difficult to interpret due to insertion and removal of quires. It was written by multiple (but unknown amount of) hands in late Caroline minuscule and proto-Gothic, probably in saec. XI-XII according to its catalogue or saec. XI^ex according to Kéry. The manuscript's origins can be traced to (northern) France according to Kéry and its catalogue. Its provenance, however, is unknown. The codex's former shelf-mark number, which reads 602 on fol. 1r, might be an indication of earlier storage or archival interest. Nothing else is known about the changes in whereabouts of this manuscript.

Contents

The manuscript is a large-sized codex with a bulky amount of folios and contains almost exclusively canonical material (including the Collectio XXX capitulorum (De ratione matrimonii)), which is dominated by Pseudoisidore's False Decretals. The manuscript also includes a very small unknown collection of canonical material. Other works included are (excerpts of) epistles by pope Gregory the Great and Pseudoisidore's Capitula Angilramni, and a few forged epistles of Isidore de Seville. Lastly, (excerpts of) works by Cassiodorus and Polemius, as well as the Notitia Galliarum have been included.

Fol. 306v of the manuscript, showing a few canons of the unknown short canonical collection

The manuscript seems to have enjoyed a particular early modern interest, as exemplified in the added picture of fol. CCCVIv. Especially in the marginalia of Pseudoisidore's works, many small early modern annotations, clarifications, and commentaries can be found. The unknown canonical collection, interestingly, seems to also have drawn some interest. This may have been due to its contents, which draws from the councils of Antioch, Nicaea, Laodicea, Chalcedon and the capitula of Martin of Braga, and decretals of popes Innocent I, Hilarius, Celestine and Leo I.

Concerning the codicology of the manuscript, it is a rather hard to trace compilation. Various folios seem to have been cut shorter at a later stage, but before the late medieval and early modern hands penned down the various marginal additions. Also note that fols. V^a-h are probably a 14th-century replacement of the original material, according to the catalogue. This makes reproducing its composition an arduous endeavour and it would benefit from more research.
