I bought a book the other day from the Speaking Tree in Glastonbury (top bookshop, loads of megalith stuff nice and cheap).
I bought Burl's 'Great Stone Circles', 1999. It looks at a handful of circles in depth. Long Meg, Stanton Drew, a few others. Includes folklore, archeology, piccies, coffee table format, all for a tenner! Job's a good 'un!
I like Chapter four - 'A Cornish Quartet'. The four circles on Land's End. On page 77 there's an old etching by Rev W Cotton. It's one of the Tregeseal Cicles, now destroyed. Never seen this before. I know there were other circles
Come to think of it, I've seen very few pictures (drawings or otherwise) of stone circles that don't exist anymore. Winterbourne Basset springs to mind. . and of course the Sanctuary.
Are there any more I wonder?
