I believe that these are just another way of trying to describe the special power of design and rendering that is present in the best of ethnographic weaving. I don't think so. Finally, and most subjective of all, is the issue of beauty. One might almost say that it is the degree to which an ethnographic rug has resisted the artistic stagnation which inevitably comes with market influences that is the measure of its aesthetic merit. They are beautiful nonetheless.
All distinctions are hard to maintain.
