20 奈良時代における左官工事の文献的研究

抄録

This treatise is written about of affairs of plasterer work in Nara Age (645AD-780AD), founded on Research of Temple Kofukuji, Hokkeji and Ishiyamatera by Dr. Toshio-Fukuyama (wrote 1943) and investigation of contemporary wall at Temple Horyuji by Member of Repair Office at the Temple. I think that the following fact was found from this treaties: material and execution of plasterer work in Nara Age have scarecely been changed compared with modern works except the use of different paste for limed plaster. Lath was braided small timber or bamboo and rope which knit it is made of stalk of rice-plant or tendril. Clay with stalk of rice-plant as hair was used for first and middle coating. White-soil or lime combined rifined fiber of hemp or paper was plastered for setting coat. It, however, is difference between the comtemporary age and the modern age that paste was made from essential juice of rice or glue. The reason why the cost of plasterer work in Nara Age was high in comprison with modern works is caused by the above fact. Craftman differed from each stage of execution, braiding lath and first coating, middle coating and setting coat. Braiding lath and first coating was acted by navvy, middle coating was by soil-men, and setting coat was plastered by artist of wall picture. Late plasterer originates with one of these proffesionalmen, soil-men, named tsuchi-no-takumi at contemporary Japan.
