What is "butaul"

Butaul (also spelled Buta-ul, with possible meaning "the son of Buta") is a name mentioned in an inscription contained in a treasure trove of gold artifacts found in 1799 in Groß Sankt Nikolaus (Romanian: Sânnicolau Mare) in northern Banat (then under administration of Habsburg Monarchy, today in Timiş County in western Romania). According to various interpretations of the inscription, Butaul was an župan, a sort of local chieftain.
