Tomb No. 44 of the Jjoksaem site is a wooden chamber tomb with a stone mound that belongs to the same period as Geumgwanchong Tomb, and the buried individual is presumed to be a royal woman (princess) of Silla around the age of 10. A number of leaf-shaped decorations using jewel beetle wings and hemispherical decorations with round pendants were excavated from the stone structure near the head of the deceased’s head. As decorations similar to these decorations have been excavated around a saddle at Imdang Tomb 5A in Gyeongsan, as a part of a black painted saddle was found in the center of this area, and based on the results of organic material analysis, it was established that these decorations originally adorned a saddle flab. By analyzing the fabric attached to decora-tions and the organic matter attached to the black lacquered frame, the following parts of the main body of the saddle flap were identified and restored: the lower plate of the black lacquered wood frame, plain hemp fabric, plain bamboo fabric, plain hemp fabric, plain silk fabric, red colored twilled silk fabric, and the upper plate of the black lacquered wood frame. The leaf shaped decorations and hemispherical decorations with round pendants were combined in a cross shape to form the main pattern, and their splendor was maximized by adding red purple colour and silk twill fabric. Nails were not used at all for this saddle flap; components were fixed with threads and knots. The decorations with round pendants protrude, making them easy to break. Therefore, the saddle flap is impossible to use when riding a horse, and the same applies to the decorations of the saddle breech. Such horse harnesses therefore appear to have been used for rituals, particularly for ancestral rites in the tomb. The restored saddle flap is the result of interdisciplinary and convergence research between archaeological experts and experts in organic matter, clothing, lacquer, and gilt-bronze. This case demonstrates the necessity of micro-archaeological research and the importance of interdisciplinary and convergence research, allowing research to go one step further beyond the analysis of archaeological objects done with the naked eye.
