Tuiyan zhengdao lun 推驗正道論.
By Wang Yiyuan 王一元 (Alfonso Vagnone).
One juan. Chinese bamboo paper in one volume. No date or place of publication.

The cover bears the title in ink.

Folio 1r gives the title of the book, and the name and zi of the author. Each half folio contains ten columns with nineteen characters in each column. The upper middle of each folio gives the title Zhengdao lun 正道論; below the fish tail the number of the folio is given. The text consists of five and one-half folios.
This booklet deals with God’s creation of the universe and of man. Since man owes his being to God who loves all men He created, it follows that men should love one another. The explanation is based on the summary of the Decalogue: love God above all things and love our neighbor as we love ourselves.
The Latin catalogue has for this number: “Jo. Soerius: Verae religionis demonstratio.” This is obviously a mistake since Wang Yiyuan 王一元, the Chinese name of Vagnone, is given twice as the author.
