A total of forty-eight manuscripts were added this week to the online repository. Trends from recent weeks continue, though the Rossiani collection edged out Reg.lat to be the largest single fond for the week, work on digitizing Reg.lat continues. Manuscripts from Vat.lat fond in the 9000s continue to be added, many from the 18th C, including multiple volumes from Gian Maria Mazzuchelli an 18th C historian and Biographer. Due to his untimely death, many of the manuscript volumes at the Vatican are research or drafts for unpublished works. Rounding out the weeks additions are two volumes of polyphonic music, one by Palestrina, from the Cappella Giulia. Finally there is a volume from the Sire collection, Sire.L.5, containing the Bulla Ineffabilis in "Irish", decorated with neo-Gothic illuminations, which imitate Insular manuscripts such as the Book of Kells.

The page to the right is from Ross.529, a 13th C Italian commentary on the Psalms. The relevant catalogues identify it to the middle of the century, based on similar examples, however I disagree. The text is consistant with the date, and I see no reason to dispute its origins. The illuminations, such as the historiated "B" to start "Beatus" on f.2v to the right, feels entirely 19th C. I hope to access higher resolution images of the page to make a clearer determination, but from the digitization, my money is on an incomplete manuscript that was "completed" before it was acquired by Rossiani in the mid 19th C. It was certainly there by the time the collection was catalogued at the end of the 19th C, as that "B" is mentioned on p.129 of the Anschütz and Oberhammer Catalogue.

The bottom border is from an early 16th C Graduale from Italy, Ross.606. Folio 33v, where the image is found, has the start of the mass for St. Claire.
