Three Volume Book of Miscellaneous Drawings
The documents are a set of three volumes of “Miscellaneous Drawings”. Many of the drawings are related to Chinese rituals. The text is written in classical Chinese. The books were published in Nihonbashi in Edo by a Japanese publisher.
It could be a Chinese manual on rituals originally published and printed in China (Kanseki), but then was reprinted in Japan. These are called Wakoku-bon (books printed in Japan) as opposed to the Kanseki printed in China, but circulated in Japan.
On the other hand the Japanese also used Kanbun (classical Chinese which they rearranged slightly and read in Japanese order) in certain instances. For example there is a drawing on mausolea layouts. And the garment below is called “shenyi”, which is recorded in the classical Book of Rites advocated by the Confucian Zhu Xi of the Song Dynasty. Zhu Xi’s philosophy was very popular among Confucian scholars in Japan during the Edo period. The publisher, Tōtoshorin, furthermore appears to have specialized in such books from China. The stamps in these three volumes are dated 1774, 1786 etc.
