Thanks for that link, Mr F.
I particularly liked the painted posts and their painted cows! v amusing and why not.
I came across this, which really relates to the other thread about rock art 'meanings' - http://www.britarch.ac.uk/BA/ba40/ba40feat.html
it's an article by Stan Beckensall about What It All Might Mean
.. the bit that caught my eye was the idea that the designs might have been painted on people, woven into clothes or even used as tattoos. I could quite go for that I think. Done boldly it would be excellent.
(Not that this was the main thrust of the article, which actually should appeal to those reading the other thread. this just struck me as a bit of a cross thread idea.)
