Hello Byrd
Thank you for the reply. and am very pleased you're a scientist.
Forget Rome this measure was around well before Rome Rollright Stones late neolithic.
I am not a scientist nor am I an Archaeologist. Did begin a course in Anthropology at Queensland Uni bur but way laid along the way and ended up as a pilot briefing officer for 20 years.
In fact that was where I became interested in measurement. Australian aviation has some crazy procedures for instance an aircraft inbound to and airport may be 20 nautical miles out and on descent from 5000 feet with a visibility of 500 meters in fog. Dealing with 3 separate measures here and one of my jobs when working at country airports was to make sure they didn't hit another aircraft which may be overflying or outbound.
I have been for some yeas a member of the EAA the European association of archaeology and in 2017 I submitted [
www.bing.com] to their scientific Committe for evaluation and it was accepted.
I presented the paper at their annual general meeting in Maastricht in 2017. .
Last 20 years been in private business.
Best
Jim
