Also, do you think all structures like this have got similar non-tomb intentions? So if you went to, say, St Lythans (only because that's somewhere I've been) that to me looks superficially similar, would you expect to find the same clues to support your Trevethy theories? That would help your argument would it not.
You'll have to excuse me for not knowing exactly what clues you're talking about because the other thread got a bit too muddy.
I think you mentioned some photos you'd taken of how the light fell on particular parts of the stone. And how the stones were aligned with..
Specifics, that's what'll convince people a bit more. And comparisons with other places?
This was suggested before but what is also important is to see if the same method provides the same results at an unrelated type of structure i.e. a control .Lanyon Quoit is ideal as it is exactly the same type of structure but has been rebuilt therefore any similar finds would have no relation to the original intention of the builders and could be a cause of the method of investigation i.e. look hard enough in your living room and you may well get the same results .
