The chapters in this volume were delivered at lectures to students of the Royal Academy of Arts in January 1904 by George Clausen, who was at that time Professor of Painting. He approaches the subject a number of ways, including specific masters, styles, methods, techniques, contexts and composition. The book offers a balanced introduction to the subject, and to the modern reader, an insightful glimpse at an approach to this evergreen topic as delivered over 100 years ago.
