Thanks Fitz, I knew you'd come up with something good. I've seen the link, I look forward to the rest of the information! I'm also trying to establish links with earlier art with which I know there's a link!! Like the ochre used by those earlier humans, it was still used to paint objects and orthostats within passage graves afterwards. Let me know when Stan's book becomes a database (on the web I guess?).
Question: have any idols ever been found at the entrances of Irish passage graves or is there any evidence ? You know the ones, rough decorated stones that have a particularly human shape. They used to do that in ancient Japan too, even the early Romans kept little statues of their ancestors.
