This was a quiet week, with only twenty-nine manuscripts added to the online archives this week. Along with more Galletti volumes on the history of Romans are two bibles of interest. The first is Vat.lat.4195, a 13th Century volume containing the Vulgate text and an index of names. Although this is a common combination in what are termed "Parisian Pocket Bibles", this volume has been localized to Sicily or South Italy based on the decoration, which is similar to the Conradin Bible, Walters W.152. A piece of f.65v can been seen below as the border, though the decorations in this volume are heavily oxidized.
A far more complex biblical manuscript is Ross.497, see f.72r to the right. No catalogue information could be found on this volume on either the Vatican site or a cursory search of Google, but the volume appears to contain three sections, a concordance, ff.2-58, a highly-abbreviated Vulgate, ff.59-253, and a later introduction on f.1r. The Introduction page has a brief text to explain the complex numeric notation scheme used to relate the entried in the concordance with verses in the text. Though more research is needed, Ben Albritton pointed out a similarity with a Cistercian numeric system. One number and one Latin letter are used to reference each entry, in red. There is also a roman numeral chapter number, in black ink.
More puzzling than the number system is the text itself, which is highly abbreviated. Although it starts with Genesis 1 on f.59r: "In p[ri]ncipio c[re]auit d[eu]s celu[m] et t[er]ra[m]...", that page ends with Gen. 2:10 "Et fluvius egrediebatur de...", skipping chunks of the intermediate text. (eg. Gen 1:6 is entirely missing "Dixit quoque Deus: Fiat firmamentum in medio aquarum : et dividat aquas ab aquis."). Much more research is needed on all parts of the text.
