Is this a record for about 3/4 of a day? 230 posts and still counting plus those deleted by the Eds...most of which were off on a tangent? :-)

Being born and raised in Jersey this is the first time I'd heard about and eventually saw rock-art. It's in the passage grave at La Hougue Bie where we used to play as kids. Click on 'back' at the bottom of the page and you'll see a drawing of it. It was this at first sight that I thought might be a crude map indicating the various megalithic remains on the island and their importance but never really got too deeply into it.

That's 300 posts + the binned ones so time for my next question in my quest to learn more about rock art.

The rock art in Europe...does it follow in line with ours here with regard to style/quality/type? Is it possible or likely that the same 'hand' was responsible for some here and also over there? In other words, any evidence that a bloke who carved some there did the same here?

Now I'm coming late to the party here, and I've not read the zillions of other posts, so apologies if I'm contradicting or repeating info elsewhere in this thread.

Yes it is possible to age new carvings to some extent. It takes bloody ages, patiently wearing down all the peckmarks. Then leave it outside long enough for a coating of yoghurt to turn into moss then lichen, and it'll look not new.

And it can be possible to differentiate different periods of carving on the genuine article. Compare the newer motifs at Hunterhegh 1, where the newer carvings have a different kind of peck mark, and the old ones are very much more weathered, with Hunterheugh 2 a few yards away, and you can see old carvings that have been partially exposed to the elements, so the upper part of the panel looks worn, but lower parts of the same motif are fresh and show all the peck marks clearly.
