〔報告〕タジキスタン国立古代博物館が所蔵するフルブック都城址出土壁画断片の保存修復

Wall painting fragments excavated from the Khulbuk site located in southeastern Tajikistan have undergone conservation treatments. The painting is dated from the 11th to 12th century, the early Islamic period. Since only a limited number of wall paintings of this era have been found, this wall painting is very important from historical and art historical points of view. The painting,which used to be on the wall of a mud brick structure,was on the ground when it was discovered during excavation. After it was lifted from the ground,its earthen plaster was removed. Thus the painting now has a very thin structure. The painting was also extremely fragile and heavily damaged. The paint layers no longer had adhesive strength and some paint had become powdery. The surface was cracked and there were many loose pieces in the relatively larger fragments. These conditions restricted the painting from being shown to the public and it was even difficult to move the painting safely. In order to stabilize the painting fragments,conservation treatments described in this article were developed. First, pre-consolidation with funori-aqueous solution made it possible to carry out surface cleaning. Then,since small loose pieces needed to be joined and placed in right positions,they were fixed by light weight cellulose clay and joined with gypsum-based grout. After stabilization of the surface, the back of the fragments was also consolidated and a new backing of TWF (triaxil woven fabric)which can support the fragments well was given. Finally, an artificial render was applied on the back of the fragments to provide enough thickness to make the painting movable. All of these treatments were successfully done, and now the painting of Khulbuk is stable
