Abstract
Monyoki contains a lot of useful drawings of medieval architecture, and the original Sonen-dinnnoh version has long been treasured in Shoren-in. We classified these original drawings according to the name of building, the rituals performed there, and the date of the rituals, to put them to academic use. We also organized the database of linguistic expressions of architecture in the text. Furthermore, we performed the same kind of classification on another Shoren-in doctrinal, Kissui-zou Shougyou, to clarify the compilation process of Monyoki through comparison, which is needed for critical analysis of the drawings.
