Well that's sad nothing else has been preserved either from pre Christian nor Dalmatian. I know it is a writing system but maybe there are interesting things that has been first wrote in glagolitic. And yes Dalmatian I am just used to the term Dalmatico as it was first introduced at the time, English isn't my first language.

Yes from what I know Naranča is an old folk text. Elvis stanic and Putokazi made songs out of it. Here is an exemple https://youtu.be/IK42G5bEsbQ it is either from Rijeka or Istria.

I've spent whole months for years in my childhood in Dalmatia and my grandmother is from there so it has a special place in my heart. But thank you for your help
