"Though I have great respect for our ancient circles perhaps it's also worthwhile looking at things from a different angle sometimes and not just accepting 'in vogue' ideas that stone circles were places of esoteric/religious/festive gathering but that some were just simple pens for livestock."
Very fair point, but extending the speculations to big showy places like Avebury is a step too far IMHO. If I didn't know you better I might think you had your tongue in your cheek and were enjoying stirring the pot! ;) Such effort, such aesthetics, such longevity - for a simple non-ritual function that could have been achieved by a wooden fence!
But small circles, yes, why not. Britain is plastered with stone animal pounds that have a similar feel to them. Wonder if anyone has analysed whether the entrances to those tend to be in a particular position? Away from the prevailing wind for instance? ;)
