I think most modern art is an ever accelerating copy of the emperor's new clothes. No one in the art world dares tell the truth about it lest the whole house of cards of art, galleries and million dollar price tags falls apart.
A friend of mine’s young son once broke a lamp while I was at their house. I said “now it’s modern art.”
When we look at ancient artworks, we are more concerned with the age of the piece and the rarity of works from that area or some modern appreciation of some piece than following onto whatever was considered the best “in its day” by the artist’s peers or the public.
So much of the value and “appeciation” aplied to works comes from academics and journalists, not other artists or the public at large.
