Stone circles have nothing left in them
[thats why archeologists don't like them]
and when they do find stuff it's from a different age [romans liked leaving coins] to when the circle was built,
Stone circles have been show to have plenty "left in them " . Often the cirle is the last architectural event after depositions of human/animal remains .An obviious example is Stonehenge where the erection of the stones came long after the creation of a ditch and banked enclosed cremation cemetery .
It's pretty obvious many archaeologists actually do like them .Any quotes from any saying they don't ?
Stuff from all periods pre and post circle erection are routinely found .
Stonehenge is a shit example to use for so many reasons, in it's first phases it was more of a causewayed enclosure [they have lots of things left in them- beakers , animal bones], then like YOU said a cremation cemetery- so was probably never a normal stone circle, which have fuck all left in them from the original builders, people who have excavated them describe them as been almost routinely swept clean- maybe for dancing feet [of which there is some folklore]. I said Archaeologists don't like excavating them [because not a lot is going to be there] not that they don't like them in general.
Your bog standard stone circle is practically devoid of anything to make one believe that they were built for any particular reason, be it religious, ceremonial, funery, ritual, feasting or whatever, that is the mystery of them because there is no consistency. I suspect I'm no different to any of you guys but when I visit a circle for the first time I'm stoked up and thinking...'Maybe this will be the one that gives me the answer'...but it never is of course and you leave feeling just as confused as ever, so I can well imagine some archaeo's privately also feeling rather negative about them!
Dancing is one argument you can back up a little and therefore maybe music!!
The Rolling Stones? :-)
