THE GETTY CONSERVATION INSTITUTE The Getty Conservation Institute (Gel), an operating organization of the ]. Paul Getty Trust, was created in 1982 to enhance the quality of conservation practice in the world today. Based on the belief that the best approach to conservation is interdisciplinary, the Institute brings together the knowledge of conserva tors, scientists, and art historians. Through a combi nation of in-house activities and collaborative ventures with other organizations, the Institute plays a catalytic role that contributes substantially to the conservation of our cultural heritage. The Institute aims to further scientific research, increase conserva tion training opportunities, and strengthen com munication among specialists.

Organized by the director of the Institut Royal, Liliane Masschelein-Kleiner and cosponsored by the Getty Conservation Insti tute, the four-day seminar took place September 21-24, 1987, in Brussels-a location that offered an especially meaningful backdrop because of its historic role as a tapestry-weaving center. On-site visits to the IRPA textiles workshop, the private work shop Gaspard De Wit in Mechelen, the "Tissus d'Or" exhibition at the Royal Museums of Art and History (featuring the four works restored at the IRPA workshop), and the "Masterpieces of Bruges Tapestry" exhibition at the Gruuthuse Museum and the Memling Museum in Bruges bore testimony to the issues raised at the working sessions. The seminar was designed as a forum for participants to present their current research and treatments, address urgent issues that have not yet received sufficient attention from the profession, scrutinize new findings, and thoroughly discuss specific problems, innovations, methods, materials, and technologies that might be proposed in the course of the meetings. In other words, the seminar aimed at estab lishing the present state of knowledge in the field. Several of the participants had attended a previous textile study group held at the ]. Paul Getty Museum in 1984 at which specific issues for further research-support materials, surfactants, the in fluence of aging, the degradation of synthetic polymers, training and standards of practice, and methods of "slowing down" the degradation of large textiles-were iden tified. Participants in the Brussels seminar followed up on many of these issues. The fifteen papers published in this volume formed the armature for this creative exchange. They focus on treatments of western European tapestries and eccle siastical embroideries, mostly from the Renaissance period, although one work, a litur gical sandal, dates back to the twelfth century, while the pilaster panels from Broni originated as recently as the 1740s. Some of the papers present general concerns, such as the development of a comprehensive conservation program for textiles at the Metropolitan Museum of Art (Nobuko Kajitani) or the importance of compiling a Foreword ix thorough technical report (Stephen Cousens). Most offer recent treatments of impor tant historic textiles as case studies in the state of the art of textiles conservation. From this mixed palette of expertise, certain dominant tones stand out. Per haps above all, participants share a concern over the perils and rewards of wet clean ing versus dry cleaning. Simply stated, the procedure that may be necessary to preserve the object from further deterioration may also run the risk of altering it irre versibly. Not surprisingly, thoughts concerning cleaning technology and procedure weave a thematic pathway through many of these papers (Marie Schoefer and Eric Houpeaux, Nobuko Kajitani, Andre Brutillot, Loretta Do!cini, Bruce Hutchison, Ksy nia Marko, and Yvan Maes). Likewise, the pervasive problem of reintegrating large areas of loss in tapestries sparked common concern and innovative approaches, as found especially in the papers presented by Ksynia Marko and Yvan Maes. Interest in the issues of mounting, display, and storage form another thread of continuity among the papers. These issues are sometimes regarded as being outside of the radius of work of the individual textile conservator. Nonetheless, fragile tapestries and embroidered textiles, such as the reconstructed fragments of the twelfth-century liturgical sandal salvaged from a bishop's tomb (Marie SctIoefer and Denise Lestoquoit), require custom-designed backing, mounting, and showcases made of materials that offer optimum protection for their vulnerable displays. The conservator's interest in controlling environmental conditions extends beyond the exhibition rooms to include storage areas as well as works in transit. Attention to these conditions is a requisite of the field. Curators are becoming aware of the textile conservator's role in the continuing preservation of the object once it has been restored (Nobuko Kajitani). The nuances of individual interests expressed in these papers offer evidence of the broad range embraced by this topic. Karen Finch, for example, exposes some of the special problems caused by Victorian textile censors who rewove discrete portions of a tapestry depicting Cleopatra provocatively resting her leg in Anthony's lap. When the inferior nineteenth-century dyestuffs faded away, the naughty leg reap peared in a blushing shade of pink. Mechthild Flury-Lemberg traces clues to the origin and history of the Toulouse antependium in its uncommon depictions of scenes from the lives of Saint Francis and Saint Clare. Rotraud Bauer surveys certain historic embroidery techniques-needle painting and or nw?-as found on a set of fifteenth-century
