I've been reading a fair bit recently about the late medieval/early Renaissance Balkans, particularly Bosnia over the course of early Ottoman rule and I'm on the lookout for primary sources from that period. I've come across Fra Matija Divkovic (forgive me my missing accents), but unfortunately, I don't speak Bosnian and sure as heck can't read Glagolitic or Cyrillic script.
I'm hoping someone in this sub might have some background with that material or even Croatian or Serbian early Renaissance texts in translation. English makes my life easiest, but I can get by with French and my very bad Latin if need be.
Self Update: if anyone else is curious, after some searching I turned up an article describing a Vatican copy of Divkovic's little Christian Doctrine in Italian. Citation below (it was hosted on Academic OneFile):
