Howburn Digger and Rhiannon,

I'm no expert on rock art, or owt for that matter, but here's my two-penneth:-

The carvings initially seem too deep, meaning a lot of effort in that type of rock. But then I consider the deep cup-marks in Cumbria, which have been carved out of hard rock. Then the shapes in the Brodick rocks don't seem to be clearly representing anything, even though I agree that they don't look completely natural. As a juror, I am still out.

Interesting all the same, especially since it's next to existing rock art. Difficult subject, rock art, as it's hard to prove if it's genuine, or how old it is.

Regards to you both,
TE.
