This book focuses on the proceedings of a meeting on the conservation of wall paintings held at the Courtauld Institute of Art in London in 1987. The papers, by an international group of experts, address both pre-conservation assessment techniques and methods of monitoring projects after conservation. The conservation of some well-known paintings, such as the Sistine Chapel, the Brancacci Chapel, and the Nefertari tomb are discussed. A definitive paper on the effect of salts on wall paintings is also included.
