" Great British painters, one might say, imitate the proverbial behaviour of buses. None come along for a century or more, then two at the same time. In the decades after 1800 there were J. M. W. Turner and John Constable, then none of international consequence, except perhaps Walter Sickert, until Bacon and Freud after the Second World War. "
