JapSin II, 27
Richan lizhi 日躔曆指.
By Luo Yagu 羅雅谷 (Giacomo Rho).
One juan. Bamboo paper in one volume, European style. No date or place of publication.
The cover bears a label with the title. There is a Latin inscription that reads: “Introductio ad Astro | nomiam | a p. Jac. Rho, S.J.”The verso of the title page mentions the collection (Xiyang xinfa lishu) and the section to which the text belongs: 西洋新法曆書，法原部，日躔, the chief compiler (Xu Guangqi): 明禮部尚書兼翰林院學士協理詹事府事加俸一級徐光啟督修, the author and reviser (Giacomo Rho and Adam Schall): 修政曆法極西耶穌會士羅雅谷撰，湯若望訂, and the proofreaders (Wu Mingzhu, Zhou Shichang, Chen Yingdeng, Zhu Guangxian, Chen Yujie, and Xu Huan): 門人鄔明著，周士昌，陳應登，朱光顯，陳于階，徐瑍受法.
There is a table of contents (three folios). The whole book consists of forty-two folios. Each half folio has nine columns, with twenty-two characters in the first column and twenty-one in the rest of the paragraph. Annotations are given in smaller type and in double lines. The title of the book and the number of the folio are given in the middle of each folio.
While consciously beholden to Copernicus and Galileo, Rho did not accept the heliocentric system, preferring to consider the assertions of these masters unproved. Possibly his hesitation was due to tactical consideration - not to disturb either the ideas held by the Chinese or the official doctrine of the Church.
