Basic historical and scientific researches of "Shiju-hattai Butsu"

该项目的目的是对57尊被称为“Shiju-hattai Butsu”的镀金青铜佛教雕像进行基础和一般研究从雕塑历史和保护科学的角度来看，尽可能多地收集这些雕像以及其他同时代标本的客观数据。每年的研究工作大致如下，除了铸造工艺的科学检验和实验研究外，都达到了预期的目标。1.共同研究（基础史料整理）通过三年内的六次研究，获得了“十州八台菩萨”和光环的全部资料。2.科学检验我们计划通过X射线荧光和铅同位素比率分析小雕像和光环，以确定其金属成分和铜的来源。然而，我们不得不离开这两个研究不完整，因为在前一个情况下，机器的变化和困难，获得样本材料在后。但我们发现X射线荧光分析有助于镀金的研究.相关实物的研究（与“十四八台佛像”同时代的镀金青铜佛像的实地研究）我们在三年内研究了分布在日本各地的大量镀金青铜佛像，并在1987年的“镀金青铜佛像”特别展览目录中发表了部分结果。4.收集研究资料（照片和专著）在三年中，制作了1267张白色照片和289张彩色照片，并收集了336篇关于“十四八台佛教”的学术论文。连同有关的雕像，汇编可以说是令人满意的。

The aim of this project is to make basic and general research of 57 gilt bronze buddhist statuettes known as "Shiju-hattai Butsu" (48 Buddhas) and 39 halos attached to them formerly owned by the horyu-ji temple and now in the Tokyo National Museum collection from the stand points of sculptural history and conservation science, collect as much objective data as possible of those figurines as well as other contemporaneous specimens. The research was done similarly each year as follows, achieving all the goals but in the areas of scientific examinations and experimental study of casting process.1. Joint research (compilation of basic historical data) All the data of "Shiju-hattai Butsu" and halos have been obtained through the research done six times in the three years.2. Scientific examination We planned to analyze the statuettes and halos by x-ray fluorescence and lead isotope ratios to find out their metal composition and the provenance of the copper. However, we had to leave both researches incomplete because of the change of machinery in the former case and difficulties in obtaining sample materials in the latter. But we found X-ray Fluoronetry helpful for the study of gilding.3. Research of related objects (on-the-spot research of gilt bronze statues contemporaneous to "Shiju-hattai Butsu") We researched a considerable number of gilt bronze Buddhist statuettes distributed throughout Japan during the three years and published part of the results in the catalogue of the special exhibition "Gilt Bronze Buddhish Statues" in 1987.4. Collection of research materials (photographs and monographs) During the three years 1267 black and white photographic prints and 289 color prints were made and 336 scholary essays about "Shiju-hattai Butsu" were collected. Together with those of related statues, the compilation can be said satisfactory.
