Julian Cope presents Head Heritage

But what about the artificial hollows in stone that aren't round? Are they still called cupmarks? Fresh cupmarks (round ones) on stones that have been under a barrow or cairn, undisturbed until recently, show the scratches made by the tools that made them. Looks like it was a bit of flint. The idea of them being inverted prayer wheels makes modern sense, as does magical properties being given to the powder that was eroded in the carving. Thom & Thom, in the third book, analyse the patterns mathmatically, but everyone pretends that their work doesn't exist! I showed a cupmarked portable stone to a world expert and the line of reasoning he was using to show the marks were naturally formed was the same argument I was using to prove they were artificial and human-made!
