The convention by which the great events in biblical or secular history could be enacted only by magnificent physical specimens, handsome and well-groomed, went on for a long time - till the middle of the nineteenth century. Only a very few artists - perhaps only Rembrandt and Caravaggio in the first rank - were independent enough to stand against it. And I think that this convention, which was an element in the so-called grand manner, became a deadening influence on the European mind. It deadened our sense of truth, even our sense of moral responsibility.
