The Croatian Glagolitic script:.
Which has some variants over time, like this one:
The text probably reads: BLIZ BJDI GSP??I which means bliže budi (GSP??I) be closer to (‘the lord is hinted to in the comments but the last couple of letters before the I can not be decyphered because they are outside of the frame of the picture)
I initially translated GSP??I to hospita (lady) but ‘lord’ may well be intended.
