May I quote that?

It should be obvious that the demand for great artists, once the type was developed as an historical category, was enormous [...] Not surprisingly, quantities of great artists were now duly discovered and, in time, furnished with properly archetypal biographies by the burgeoning discipline of art history. [...] Inevitably some of the great artists inducted into this role fill out with less success than others. Even so, a fair or just good artist is still a servicable item in today's museum business.
