The author has written a new introduction to his book. In it he defines the scope, high degree of skill and professional discipline coupled with increasing scientific methods utilized by today's art historian in order to establish criteria and to develop aesthetic perception. Instead of attempting to describe art history in terms of concepts and abstractions, the author gives the reader a set of case histories.
Mark Roskill was professor of art history at the University of Massachusetts, Amherst. He is author of The Interpretation of Pictures and coauthor with David Carrier of Truth and Falsehood in Visual Images.
