Travers Newton I I 2 Condition and Conservation Report Cornelia Peres Foreword This CAHIER VINCENT examines two recent restoration projects involving works in the collection of the Van Gogh Museum (Vincent van Gogh Foundation): Gauguin's Portrait of Vincent van Gogh Painting Sunflowers, which has not been on display for several years because of the deterioration of its jute support, and Van Gogh's Aries triptych of orchards, consisting of The Pink Orchard, Peach Trees in Blossom and The White Orchard. These restorations, which were carried out on the eve of the 1990 Van Gogh centenary, brought a great deal of new information to light and gave us a deeper understanding of the artist's working method. The purpose of the CAHIERS VINCENT series is to make source material available to the international community ofVan Gogh scholars. This latest volume, which presents the results of restoration projects, departs from that aim to the extent that this time it is not documents that are the primary source, but some of the artist's own paintings, which have yielded a valuable insight into the way they were exe cuted. There is a growing realisation that the pictures in our care have undergone a considerable transformation since they were painted over a century ago. Leaving aside deliberate interventions during earlier conservation treatments, it has been time itself that has wrought the greatest changes. Many pigments, for example, have lost much of their original hue, which has occasionally brought about dramatic shifts in the balance between different passages within a painting. We have to be fully aware of these discolourations if we are to interpret the pres ent image correctly. With an artist like Van Gogh, who was intensely interested in colour theory, it is essential to supplement the evidence of one's own eyes with the knowledge obtained from specialists. The Van Gogh Museum's conservator, Cornelia Peres, was responsible for the general concept of this CAHIER, and for inviting the international group of contributors, comprising conservation specialists, scientists and art historians. Among these I would like to single out Paolo Cadorin, not least because Ms. Peres received her first training under his guidance. On behalf of the joint editors, Cornelia Peres and Louis van Tilborgh, I would like to express our debts of gratitude to all those who have been directly or indirectly involved in the conservation treatment of the works under discussion, and in particular to guest conservators Carol Stringari and H. Travers Newton, conservation assistant Mette Marie Bang, art historian Vojtech Jirat-Wasiutynski and, last but not least, to our colleagues at the Centraal Laboratorium in Amster dam. During the editorial stages this CAHIER benefited immensely from the expert advice of conservator IJsbrand Hummelen and translator Michael Hoyle. Rene Gerritsen carried out most of the technical photography in the Van Goghmuseum. As with the previous volumes in this series, we are grateful to the Vincent van Gogh Foundation for its financial support.
