I dissect calendars in Books of Hours and keep a close eye on the Vatican Library, sometimes in that order. https://www.cokldb.org/ https://www.wiglaf.org/vatican/

Ott.lat.1508 seems to be medicinal. I also saw Averroes and might have gotten confused between his medical and his philosophical works

@maklelan.bsky.social Have you done an episode on the very end of Genesis (Parshah Vayechi in the Jewish reckoning, chapters 47-50 or so)? The "blessings" are so weird and layered that it might make a good analysis topic

What do we know about the printing technology? Specifically my interest is in what the type was made of, if we know, and if it was mass produced.

I can try to work something out, but I store the dates as relatively unstructured data, so it could be "1525" or it could be "1525-1535" or it could be "16th C" or even "14th C, 15th C, 1275" for manuscripts of several parts

Thank you, the database has been updated. Is there any way to query PhiloBiblon via API, or the like? I'd love to get the list of Vatican MS into my DB so I can know when to cross-link the entries

Just a note of clarification, the Vatican has two different departments, the Archives and the Library. I only pay attention to the library (Biblioteca Apostolica Vaticana/BAV) which has manuscripts, not to the Archives (Archivio Apostolico Vaticano, formerly the Archivum Secretum Vaticanum).

That would be an interesting Dadaeaque project. Take hallucinated citations and force the genAI to create the paper. See if the fake papers cite each other in some sort of web of lies

This MS is extremely well studied, probably because it was published in Paleographie Musicale 14 in 1931. So not only was a printed facsimile out in the world, but PM indexes things, so it's easier to work with than many similar volumes

#HistorianSky and #MedievalSky I need advice. What is a good Mac-compatible word/text processor for writing articles? I've grown to hate MS Word, but I like the Zotero integration. I want an application, not an online thing (eg. not Google Docs).
