nerally used in conservation practice and the ethical problems of their removal were examined and discussed. At the wet treatment of the funeral coat-of-arms the floating of the painted layers from the paper could be expected. Such a binding agent was needed that penetrated into the pigments and fixed them to the paper, and that could be left on the surface. Accordingly, isinglass glue a binding agent similar to the original one was chosen. After having erased the paper and following the removal of the large number of fly-specks, wet cleaning was applied on a high-capacity sucking table with regard to the peeling and water-sensitive pigment layer. The peeling pigments were consolidated after the wet treatment of the object but before drying. Isinglass glue of 7-8 % was applied on the painted surfaces in two layers. The missing parts were replaced with manual leaf-casting on the right hand side of the paper on the sucking table. Still on the sucking-table, the paper was mounted on Japanese paper with the mixture of rice starch and methyl-cellulose. Finally, the object was covered with a non-woven polyester cloth and pressed until it was smooth and dry and the original stretching rods were reattached. The last step was the preparation of an envelope from acid-free paper, which protects the object from mechanical injuries and pollution during storing. The object was conserved within the frames of object conservator training conducted in the co-operation of the Hungarian University of Fine Arts and the Hungarian National Museum in the academic year of 2002/2003. Tamás Peiler was the supervisor of the diploma work. Conservation of a text-book from the 16th century Marianne Érdi Sebastiano Castellio’s textbook from the 16th century, titled Dialogorum sacrorum libri quatuor is preserved in the Old Prints Collection of the National Széchényi Library. This volume is the 24th edition of the textbook printed in Bautzen, Germany, in 1564. The book covered with wooden boards and bound in a dark brown singlepiece leather was prepared with dies and rollers and decorated with goffering. The wooden boards split into two, their edges were indented and one third of the binding leather was missing. The two clasps that had held together the body of the book got lost. The title page and several leaves were missing, and the paper material was spotty, torn and weakened at several places. Notes made by the original owners were found on the leaves of the book and on the multi-layered endpapers. The aim of the conservation was the complete conservation of the extremely poorly preserved binding and the leaves. The leaves of the book had to be restored into a condition that the pages can be turned and the book can be read, the binding protects the body of the book, while we had to preserve the specifics of the original production technology. The contemporary notes also had to be preserved, the fragments hiding on the boards had to be uncovered for research and every piece of information related to the history of the object had to be retained. The best conservation methods and materials were chosen according to the results of the analyses of the technology and the materials. After the dismantling of the book, the loosely adhered pollution was removed from the surfaces of the 259
