It never really occurred to me before that the impression of art history one gets from books and tv documentaries is extremely distorted towards high quality. The popular books want to get people excited about classical sculpture (say), so they show the very best of the best, from the geographic heartland and historical apex of classical sculpture. But of course most art is not as good as the very best, and in fact the median is usually rather crappy.
I had the opportunity to gain some insight into this yesterday when visiting Avignon, which has a sculptural museum with a permanent exhibit of mostly the Franco-Roman oeuvre from the early imperial period.
