yeah the situation with the etymology of byzas is complicated because i can't locate the sources i need and as you said given the state of the evidence a definite answer may not be possible i want to find out the attestations of the name and its accepted variants byzas byzes etc and see whether the bhugo goat ram etymology has any evidence for it other etymologies i'm looking into is whether any sources have made a connection between the illyrian parthini and the persian parthians and partha was also another name for sanskrit arjuna whose name means bright did partha also mean bright i wonder because i've seen literature discussing whether the illyrian parthini and parthenon may not derive from a thracic or illyrian word for white or bright parth similar to albanian bardhe afghan name
