Julian Cope presents Head Heritage

I think they must be the Longstones, well two of them anyway, because nothing else is shown along the 'trackway' in that section is it. And looking at them carefully I believe two appear to be set on one side and two on the other albeit with a stone missing between each one and the track maybe just shown wider by Stukeley to make it stand out more.
And the 'track' running straight up off the avenue I suppose could take the line of the modern-day road leading to Avebury Trusloe don't you think? Its position looks about right considering it bounds the field that houses the Longstones at the end of the short lane from the A361.
Well the possibility of a 'Sanctuary' at the end of the BA was pure speculation on my part fuelled by the presence of so many burial mounds around the Fox Covert area. It reminds me so much of the real Sanctuary area without the Ridgeway. And of course if there was one and it had been destroyed by the time S was in the area I don't suppose there was a need for him to pass comment.
One other thing. What do you make of the 'bump' to the far left of the drawing? Do you think that's meant to represent the bank of the Great Circle? Can't think what else it would be otherwise.
