Is GA 2021 Part of the Same Manuscript as GA 1848?

Working on a footnote for the forthcoming Textual Commentary on the Tyndale House Greek NT, I was doing a little digging into the manuscript collection of Paul Pétau. Mill used three manuscripts from this collection for his edition of the Greek New Testament, which he labels as Pet. 1., Pet. 2., and Pet. 3. 

Pet. 1. seems fairly clearly to be the same as, Nederland Leiden Universitaire Bibliotheken Voss. gr. Q° 77, GA 328, Diktyon 38184. Pet. 3. also seems to be fairly clearly the same as Vaticano Città del Vaticano Biblioteca Apostolica Vaticana (BAV) Reg. gr. 179, GA 181 + GA 2819, Diktyon 66348, a manuscript used by Zacagni for his edition of the Euthalian apparatus. 

Unfortunately, Pet. 2., the manuscript I actually wanted to identify, has proved rather harder to track down. By Tischendorf’s day, it had already disappeared. In the prolegomena to Tischendorf’s edition, written by Gregory, it is noted that “hodie latet” (now missing). Despite this, Tischendorf seems to have cited this manuscript from Mill’s edition, using the numbers 39 for Acts and the Catholics, 45 for Paul, and 11 for Revelation. The reading of greatest interest is, of course, Revelation 13:18, where Mill notes that Pet. 2. reads χιϛ, or 616. Unfortunately, I was not able to track down any manuscript with this reading. 

However, it was this research that lead me to GA 1848. This manuscript, which was also once part of the Petau collection, has been divided into a large number of individual volumes, now divided between the BNF and the Vatican. BNF Grec 108, 109, 110, 111 and BAV Reg. gr. 76 are all known to be a part of this same manuscript, which was copied by Georgios Hermonymus in the late 15th century. 

BAV Reg. gr. 68] (GA 2021) has the same copyist, also comes from the Pétau collection (according to Xavier Rincel’s dissertation). On examining the images side by side, they also share a number of distinctive formatting features, including a rubricated running title, large gaps for initials (mostly not filled in), and general mise-en-page.

According to the Liste, GA 1848 is a copy of GA 467, also copied by Georgios, and which has a very similar layout. Since GA 467 contains Revelation, if GA 1848 is a copy, it seems reasonable to suppose that it also would have contained Revelation. Given that GA 2021, in addition to all the other features, has been bound into the same miniature volumes as the different portions of GA 1848, it is very likely part of the same manuscript. If this is confirmed by other researchers, the two should be linked together in the Liste. 

When I initially discovered this, I had hopes that GA 2021 would prove to be the missing Pet. 2. However, a quick cross-referencing of of the Sonder- and Singulär- lesarten in the TuT of GA 2021 with the readings of Pet. 2. in Mill’s apparatus, as well as a few checks of the readings of Mill in GA 2021 itself, did not reveal any significant correspondences, leaving Pet. 2. “hodie latet” in our day, as it was in Gregory’s.
