Qinding xinli ceyan jilüe 欽定新曆測驗記略.
By Nan Huairen 南懷仁 (Ferdinand Verbiest).
One juan. White bamboo paper in one ce, forty-two folios (ff. 8–10 and 29–31 are missing).

The title page is xylographed in Latin from the handwriting of Verbiest with the date 1668, which engraving was done in Beijing: Astronomia Europaea | sub Imperatore Tartaro Sinico | Cam Hy appellato | Ex umbra in lucem revocata | A P. Ferdinando Verbiest | Flandro Belga Brugensi | E Societate Jesu | Academiae Astronomiae | in Regia Pekinensi | Praefecto | Anno Salutis M.DCLXVIII.”

On the twenty-first day of the eleventh month, the seventh year of the Kangxi reign, we had an unexpected visit from four Grand Secretaries sent by His Majesty, namely, His Excellency Wu Gesai 吳格塞, His Excellency Duo Nuo 多諾, His Excellency Zhuo Ling’an 卓令安, and His Excellency Fan Chengmo 范承謨, all of them now deceased. His Majesty wanted to know whether the calendars then issued were correct. My reply was that they were very erroneous and that I had solid argument for saying so. There and then I pointed out the errors of these calendars. His Excellency Duo referred my reply to the emperor. The following day (22nd) an imperial order summoned me, An Wensi 安文思 [Gabriel de Magalhães], and Li Leisi 利類思 [Lodovico Buglio] to present ourselves at the Donghua Gate. On that same day the officials of the Imperial Observatory, Ma You 馬祐, Yang Guangxian, and Wu Mingxuan, were also there. [There followed a disputation between Yang, Wu, and Verbiest]. It was proved that the calculation of the calendar was incorrect and by imperial order the Qizheng minli 七政民曆 was compiled in the eighth year of the Kangxi reign by Wu Mingxuan, then Vice president of the Imperial Observatory, to be examined carefully for definite errors . . .
