Mr Tiompan, am I right in thinking that Fyfield is the only one on sarsen though? It's a bugger to carve is sarsen, even with modern metal tools. I've tried, and have found it quickly blunts everything from carbonised steel to Pike'O'Stickle andesite.

The Fyfield stone is mostly cups, though there is a weird 'slug' shaped thing (blame Goffik, it was he who branded it a slug) which seemed artificial, so it would be a good thing to look at as comparison. The things on Stonehenge are metal-tool jobbies, so would be a bit misleading for comparison with your bog-standard rock art, which would of course, be pecked out with stone picks (allegedly). Mind you, Fyfield looks ground out rather than pecked, so maybe that line of thought is a red herring.

Most interesting stuff Slumpy :)

Hi Hob , it's the only one I'm aware of but sadly have yet to see it . If there are lots of natural holes maybe it's a case of enhancement .The bowls at Knowth and Newgrange are described as being granite and they have incredible workmanship and there is rock art on Aberdeenshire granite , dunno how sarsen and granite compare on the Moh's scale but like you say it needn't have been pecked .

We only need to look at stonehenge to know that sarsen can be worked with relative ease using stone tools. I would guess that it is the skill and experience of the mason which is the most important factor when looking at any worked stone.
Regarding Moh, as you know the scale is applied to minerals not rocks, I guess that there are too many variables, depending on the conditions of the deposition of the rock, to allow an absolute value.
