Study on chief factors to compose ‘Hoshi-mandara' and on peculiarity of ‘Chu-son'-from artistic point of view which links religion to science-

从宗教和科学的角度分析《星曼陀罗》(《星曼陀罗》或《北斗七星曼陀罗》)的创作特点，找出决定其创作的主要因素。我研究了各种现有的‘Hoshi-mandaras’。理解“楚子”(居于曼陀罗中心的形象)的特殊性和其他元素的作用是阐明观点的前提，因此，拍摄个人形象是必不可少的。由于一些宗教限制不允许检查或拍摄几种官话和其他重要作品，因此浏览‘Hoshi-Mandara’省的信息量有限。然而，这项研究的相当大的成就之一是建立了原始的照片数据库，其中包括镰仓时期之前的一些星官照片，包括《楚孙》、《北斗七星》、《九个发光体》、《十二生肖》、《二十八宫》或基本元素的个人照片。因此，该数据库提供了大量的信息，每个元素出现在‘星-曼德拉’根据目前的分析，找到每一个形象的肖像特征，一定有某种形式的交流之间的星光教派和天台教派。继续对每一张照片资料进行进一步的分析，是为了了解构成‘Hoshi-Mandara’的主要因素。

To analyze distinctive features in composing ‘Hoshi-mandara'(‘Star mandara' or ‘Mandara of the Great Dipper') from religious and scientific point of view and find chief factor to decide its compose. I examined various existing ‘Hoshi-mandaras'. As understanding the peculiarity of ‘Chu-son'(the image which stays at the center of mandara) and roles of other elements is premise to make the point clear, taking photos of individual images was essential. Permission to examine or take photos of several mandaras and other important works being not given under some religious restrictions, the amount of information to look through the province of ‘Hoshi-mandara' was limited. Nevertheless, considerable achievement of this study, one of which is inserted in the report of study, is that the original photo-database was made up, which of some ‘Hoshi-mandaras' before Kamakura period, including individual photos of ‘Chu-son' ‘the Great Dipper' ‘the Nine Luminaries' ‘the Twelve Constellations of the Zodiac' ‘the Twenty-eight Stellar Mansions' or the basic elements. Thus the database gives a lot of information about each element which appears on ‘Hoshi-mandara' According to the analysis so far to find iconographic features of each image, there must be some kinds of interchange between Singon sect and Tendai sect. To continue further analysis of each photo datum is to shed light on understanding principal factors to compose ‘Hoshi-mandara'
