Abstract
In my previous paper, I classified about twenty Buddhist architecture to have been built as the eighth century in Japan into some types according to the relation of the inside or outer measurement near the column or the daito (capital) between the longer bay and the shorter bay. Then I have supposed the ancient module measurement is not far from a radius of column or one half of the length of daito in each architecture. So, I tried to formulate the relation (ICO type-division) on the above mentioned supposition. In this paper, I tried to calculate with the expression as to the distribution of bays of the five and three storied pagodas in ancient Japan, the Horyuji-Gojuto, the Hokkiji-Sanjuto, the Horinji-Sanjuto (by the document), the Toto (East pagoda) and the Saito (West pagoda) of the Taimadera-Temple, the Kairyuoji-Gojuto, Muroji-Gojuto, and the Daigoji-Gojuto. As the result of the research, the distribution of bays of each pagodas are composed of the multiple of the approximate measurement to the radius of column or one half of the length of daito in each of them, and at the first story, they are classified into four groups, 7+10+7, 6+8+6, 8+10+8, and 7+8+7, and the balance of the longer bay and the shorter bay is 1, 2, or 3 multiple of which I suppose the module or unit measurement.
