No covering , no contemporary remains , it is a table after all . There does seem to be a shift away from viewing portal dolmens as "tombs" e.g. Bradley , Richards & Whittle . The fact that the capstone , in some cases , came from the site itself is interesting . Whittle described them as "stones tha float in the sky" .[/quote]

revising my fieldnotes on cromlechs round St.David, one thing I did notice, I think of it as the fat 'diamond' shaped capstone, with one of the points to the front, it happens on Coetan Arthur, Carn Llidi,(double chambered), White House and St.Elvis (double chambered) probably there are more, a local tradition of construction maybe. Daniels describes three of them as the 'earth fast' sub megalithic tradition, which is a sort of lazy way of raising capstones....
