'Peter Williams is a master of putting question marks where they belong. He is wise enough to admit that definite answers are rarely possible. Nevertheless, guided by the 1754 Obituary, he gives splendid food for thought with his penetrating insights and truly erudite suggestions.' Gustav Leonhardt
