Fair enough - to hoist myself by my own petard, all things might be considered Folklore on a Designated Folk Forum, even those things which might not be considered Folklore by those actually involved with the study of them. But then again when the Daily Mail (and Fortean Times) are making connections to The Garden of Eden, maybe Folklore is exactly what we're dealing with here...

Do these mysterious stones mark the site of the Garden of Eden?

Whoever built it, we can be sure it wasn't horses...
