Analysis of information sources in references of the Wikipedia article "Guduscani" in English language version.
Whether Borna was primarily the leader of a group called the Guduscani remains disputed. The passage from the ARF mentioning the meeting at the imperial court in 818 can be read in two different ways: that Borna was dux of the Guduscani or that he was dux Dalmatiae, attending the meeting at the imperial court together with the deputies of the Guduscani and the Timocani who had recently defected from the Bulgars to the Franks. The Vita Hludowici reproduces the same information but only mentions the deputies of the Guduscani and Timocani without naming Borna.
