Jianpingyi shuo 簡平儀說
Transmitted orally by Xiong Sanba 熊三拔 (Sabatino de Ursis) and written down by Xu Guangqi 徐光啟. One juan. Bamboo paper in one ce with a paper case. No date or place of publication.
The cover bears a label with the title (only half of the character 說 is left) and a Latin inscription: “Modus inquirendi stellam | existentem in medio coeli | a p. Sabbathino de Ursis | S.J.”
There is a preface (four and one-half folios), dated 1611 (Wanli 39), by Xu Guangqi. Folio 1 bears the title of the book and the names of the authors: 泰西熊三拔譔說 : 吳淞徐光啟劄籍. Each half folio consists of ten columns with twenty-two characters in the first column of each paragraph and twenty-one in the rest of the paragraph. The title is given in the middle of each folio and the number of the folio below the fish-tail. On folio 1 under the number of the folio, the name of the block carver is given: 李再禎刻 (wooden blocks carved by Li Zaizhen). The main text consists of twenty-one folios.
In his preface Xu Guangqi tells that the jianpingyi (an instrument providing the orthographic projection of the sky, according to the Ptolemaic theory) was made by Sabatino de Ursis himself and presented to Matteo Ricci, who was pleased with it. Later Ricci explained it to Xu Guangqi, who took down the explanations. Xu then showed his notes to Sabatino, who thought the treatise a little short and therefore declined to have it published. But at the insistence of Xu he finally agreed. Xu considered this book as a fundamental work for calendar makers.
