lire le livre Condition : The Ageing Of Art

The paintings we see today in museums, galleries, churches and temples are often much altered by the centuries. Pictures can split, rot, be eaten by woodworm, warp, blister, crack, cup, flake, darken, blanch, discolour, become too translucent and disappear under a centuries-old varnish; and they can also suffer from the efforts of their owners to rectify these situations: they might be transferred, relined, ironed, abraded or repainted. Anyone considering a work of art needs to establish at the outset how much it has changed since it was first made. This act of understanding is far from easy. We need to develop a knowledge of the physical and chemical processes which have brought paintings to their current state, in the hope that we can imagine their reversal. And we have to look as much as we can at a wide variety of paintings, so we can learn to distinguish those in a worse or better state of preservation; we have to try to understand what it is about a picture that differentiates good and bad condition. Theories of art history have been built on works whose appearance is made up of little more than repaint and decay, and the beginner needs to be warned about the many pitfalls dug by time for the unwary. This book is meant both for that beginner and for the qualified practitioner who might have missed a step along the way. While there are many books on conservation and restoration, there is nothing which focuses specifically on condition. The plan here is to provide a hands-on introductory text, which can be used as a first orientation in the study of condition, and can remain as a basic reference work when the reader s studies have progressed further. It should appeal to anyone with an interest in art. Far too complex for their own good, European Old Master pictures by the likes of Cranach the Elder, Raphael, Leonardo, Poussin, Vermeer, Rembrandt, Canaletto, Gainsborough, Turner and Van Gogh rely for their delicate effects on layers of fragile materials, all of which are subject to change and decay. No-one can enjoy them to the full without an understanding of how and what they may have survived, suffered or lost in the journey through the years.
