In the generation preceding the development of modern methods of communication and the rise of photography, no one suspected how many undescribed treasures lay hidden in palaces, country-houses, and provincial museums. A new edition of Smith's "Catalogue" has long been needed. Opinions as to the genuineness of many pictures have
