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

本项目的目的是从雕塑史和保护科学的角度，对57座被称为“Shiju-hattai Butsu”（48尊佛像）的鎏金青铜佛像及其附属的39个光圈进行基础和一般研究，尽可能地收集这些雕像和其他同时代标本的客观数据。每年的研究都是类似的，完成了所有的目标，但在科学考试和铸造过程的实验研究领域。联合研究（基础史料汇编）通过3年6次的研究，获得了“shiji -hattai Butsu”和光环的全部资料。我们计划通过x射线荧光和铅同位素比值分析小雕像和光环，以找出它们的金属成分和铜的来源。然而，由于前一种情况下机器的变化和后一种情况下样品材料的获取困难，我们不得不离开这两个研究不完整。但我们发现x射线荧光法对镀金的研究有帮助。相关物品研究（《石柱-hattai Butsu》同期鎏金铜像现场研究）我们对三年间分布在日本各地的相当数量的鎏金铜像进行了研究，并将部分研究结果发表在1987.4年“鎏金铜像”特展目录中。研究资料（摄影、专著）三年间，共拍摄黑白相片1267张，彩色相片289张，收集“shijuhattai Butsu”学术论文336篇。与有关造像的汇编一起，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.
