A tip o' my glass back at ya Sir! So it is called Khua by the Udeghe tribal people of North Eastern Russia and called Diable by some North American tribes. Again I must reference Drumming On The Edge Of Magic by Micky Hart wherin he lists dozens of tribes worldwide who use(d) the bullroarer & what they called it as well as denoting the spinning disk as "diable". Mr. Hart is currently working with the Smithsonian to catalog rhythms & rhythm instruments of tribal peoples worldwide; he is by any accord a master drummer.
Excuse me Turtle, but it's called Khua.
While it is arguable if the Apache descend from the Anastazi or Aborigine , they have a similar view of the bullroarer, i.e. in both Apache & Aborigine society the device is forbidden to women. One Aborigine tale I heard has the men losing a bullroarer when the string broke, and when a woman found it & took it home the men slaughtered the entire village when they discovered the finding.
I have a friend who has spent some time digging Anastasi ruins (within academia of course; strictly legal!) with an eye to clues about the use of mathematics. Next time I hear from them I'll try a little digging of my own in their mind.
