The art and architecture of the past that we know is that which remains. The best is that which remains where it was painted, placed or built. Most of the art of the past that could be moved was taken by conquerors. Almost all recent art is conquered as soon as it's made, since it's first shown for sale and once sold is exhibited as foreign in the alien museums. The public has no idea of art other than that it is something portable that can be bought. There is no constructive effort; there is no cooperative effort. This situation is primitive in relation to a few earlier and better times.
