A fascinating start to Ephesians in GA 2772 (Ecclesiastical Historical and Archival Institute of the Patriarchate of Bulgaria, EHAI 236). In addition to the column layout switch after 1:2, the word Ἐφέσῳ is also conspicuously underlined. How I wish the top right of the page hadn't been torn out!

An excellent addition to the team (though we'll miss her back in Leuven)!

Well-deserved congratulations to @sofiemoors.bsky.social on a successful PhD defense! It was such a pleasure to meet you in person, see the fruit of your research, and celebrate with you and your colleagues. I look forward to seeing your future accomplishments and collaborating with you!
Afgelopen vrijdag mocht ik mijn proefschrift Codex en code verdedigen. Wat een dag was dat! Bedankt aan iedereen voor het enthousiasme. In het bijzonder veel dank aan mijn promotoren @mikekestemont.bsky.social, @remcosleiderink.bsky.social, Karina van Dalen-Oskam en de juryleden. Op naar meer!!

Just noticed a cool new update to the INTF Virtual Manuscript Room: when you index the biblical contents of a manuscript, the interface makes an initial guess on the content of a page!

A new version of teiphy (v0.1.27) is out! Thanks to contributions by Rob Turnbull, the process for converting TEI collations to various phylogenetic software input formats now makes better checks for malformed inputs. Check it out on github.com/jjmccollum/t... or get it with pip install teiphy

Something fun's going on in the bottom margin of GA 2675 (Holy Monastery Panagia Kato Xenia MS 14, 14th century) on this page of Ephesians, but I'm not quite sure what! I thought it might be a practice alphabet, but it doesn't look like the Greek alphabet to me. Any ideas?
The open-cbgm library (github.com/jjmccollum/o...) and open-cbgm-standalone utility (github.com/jjmccollum/o...) have both been updated to v2.1! In both cases, dependencies and build settings have received a needed update. (Thanks to Daniel Ridings for reporting build issues!) (1/2)

If you’re teaching #Greek, #palaeography, #manuscripts, #textcriticsm etc. this coming year, consider adding my website to your course assignments or resources. It’s free, I don’t collect/sell your info, and it’d be nearly impossible to cheat with AI. See 🧵 for details
My (free) website for learning to read from Greek manuscripts is available. Still some tweaks to be made but it’s ready with 12 lessons, tips and hints, downloadable reports if you use it for a class, and links to lots of resources. Please share and give feedback! xeirographa.com
It's good to see that the latest paper by @jbcamps.bsky.social and other members of the @lostma.bsky.social team is already making an impact!
How do we calculate loss of written works? A depressing but important new study notes that "the loss was far greater than scholars once thought. Researchers estimate that up to 60% of medieval literary works and more than 95% of the manuscripts that once carried them have disappeared over time." 📜🖋️
Requesting help from anyone out there with a good eye for Latin paleography! In the Latin side of GA 628 in Eph 3:1, there is a marginal note/correction and a supralinear correction, both pictured in the screenshot below. My questions about these two features follow in order.
Exciting work by a great team!
Freshly out in @pnasnexus.org: "On the transmission of texts: Written cultures as complex systems" The first major publication of project @lostma.bsky.social , where we lay down our methodology for studying the transmission, evolution or disparition of texts. /1 #science 🧪
I dunno if this is offensive to say because I seem to upset people when I say this, but humanities people should consider joining us, or at least join us in decoupling from Word and other MS products where we can... and @acollierastro.bsky.social says it more convincingly than I can!
We are excited to announce that our forthcoming book, Greek Prepositions in the New Testament: A Semantic Description, is officially listed for preorder.
Forthcoming: Greek Prepositions in the New Testament: A Semantic Description
We are excited to see that our forthcoming book, Greek Prepositions in the New Testament: A Semantic Description, is officially listed: Baker Publishing Group Amazon Logos Bible Software We are in the midst of the laborious process of reviewing galleys right now, but hope to see proofs in the coming months. Originally, the hope had been that the book would be available this fall in time for conferences, but we took some extra time this past January to add visual figures and image schemas for each preposition article with the hope of improving its usefulness for students.

More fun news: a paper I co-authored with Pasi Hyytiäinen and Tim Finney is now available as an advance article in Digital Scholarship in the Humanities: doi.org/10.1093/llc/.... We investigate the validity of the contested paradigm of text-types using a battery of computational approaches. (1/8)
An excellent read about an important manuscript and the scarred history that it and witnesses like GA 02 have in common.
Murder. Theft. Tischendorf. Codex Alexandrinus. GA 81. What brings those together? A journey to Alexandria, a trail of manuscripts, and a mystery with more twists than expected, hidden in the story of a grieving library: futureofthepastlab.com/2026/05/27/c...
Question for #Phylogenetics folks: SSE models are designed to address situations where character states influence speciation and extinction, but are there any models for influence in the opposite direction? I'm interested in scenarios where branches' mutation rates depend on birth/speciation rates.
Proofs have arrived. Looking forward to the end product in early July!
The slides for my talk at KU Leuven's upcoming GA 629 conference are coming together nicely! I made a few tweaks to the KU Leuven LaTeX presentation style at gitlab.kuleuven.be/campus-geel/... to match some more recent official PowerPoint templates better. Check out this title slide!

Some Greek NT scribes would expand common nomina sacra like υς (for υιος, "son") and πνς (for πνευματος, "spirit") to their full forms when they did not have a divine referent. But this might be the first time I've seen a nomen sacrum corrected to this end! Here's Eph 2:2 in GA 1956:
teiphy v0.1.26 is out with another requested feature! If your collation contains many correctors and you only want to fill in the extensive ones (presumably so you can drop out the rest as fragmentary), you can do so with the new --fill-correctors-threshold option. github.com/jjmccollum/t... (1/3)

A great introductory post on how the CBGM works and why it was developed for NT textual criticism, including a bibliography of helpful resources for further reading! (Thanks for the shout-out to my work on the open-cbgm library, @criticaltexts.bsky.social!)
For anyone who wants to understand the CBGM a bit better, here’s a post on what it is, what it isn’t, and why it matters for New Testament textual criticism and beyond. criticaltexts.com/the-one-with...
