[An examination of the Cúnzhēn Huán Zhōng Tú]

A human dissection autopsy was performed in China in 1045, resulting in the production of the Oū Xī-fang Wū Zàng Tú. Subsequently, between 1102 and 1106, Yang Jie augmented this with the Cūn Zhén Tú. Both of these have not been preserved. The author has re-examined these on the basis of materials (preserved in Japan) left by the 16th century figure Gen'un. 1. The material used by Gen'un was the Cun Zhēn Huánzhōng Tú, and he did not cite directly from the Oū Xī-fang Wū Zàng Tú. 2. The drawing of internal viscera cited by Gen'un is the same as that cited in the Ton'ishō. 3. Cún Zhēn Huánzhōng Tú is comprised of two sections; the drawings and explanations in the Cún zhēn Tú deal with internal viscera, and those of the Huánzhōng Tú with meridians and acupoints. 4. The explanatory text in the Cún Zhēn Tú cited by Gen'un accords with the citation in the extant text of the Xīnkè Huá Tuó Nèizhao Tú. 5. Kōzō Watanabe has argued that the Ton'ishō cited the Cún Zhēn Huánzhōng Tú in its entirety, but this is incorrect. Rather, the citation is only a partial one.
