My degree is in Celtic Studies. This kind of discovery may be surprising to those not versed in it but not those who have studied these languages. Some of the best preserved Old Irish, for instance, is in St. Gallen in what is now Austria and Milan.
There is still an entire Medieval European world out there in the archives still waiting to be discovered. Sadly, there are not many of us who have the skills to do this and we are not paid very well or often not at all.
Oh that's interesting! In my mind we are now on the cusp of being able to scan all these archives and have them be read by LLMs (in a first pass). Do you agree with that assessment, or am I being naive here?
Even digitizing sources this old entails quite a lot of manual labor.
