"Tianwen lüe 天問略 (Questions about Heaven) .... Dias’ work was devoted to descriptive cosmology rather than mathematical astronomy. [A Chinese Christian convert who collated this text was Xu Leshan 許樂善 (ca. 1544-1625/26; jinshi 1571, baptised as John in 1610).] Dias' Tianwen lüe 天問略 (Epitome of Questions on the Heavens, 1615) is best known for its appendix, in which Galileo Galilei’s (1564-1642) invention of the telescope and the new observations he made with it were reported; the details of the surface of the Moon, the phases of Venus, the four satellites of Jupiter, the objects of which Saturn’s rings are made, many stars in the Pleiades and the Milky Way. Information travelled fast from Europe to China: Galileo’s Siderius Nuncius had been published in 1610, and his observations confirmed by Jesuit astronomers of the Roman College the following year. The main body of the Tianwen lüe, however, was a description of Ptolomaic astronomy; Dias' preface pointed out that the universe described was the work of God." -- Cf. Standaert, N., Handbook of Christianity in China, pp. 404, 693, 695, 712-713.
