In the Russian collection of Tangut material there is a manuscript which describes a meeting between Confucius and an old sage. It is generally assumed that it is a translation of a Chinese work but attempts at identifying the source text have not been successful. The Tangut title survives on the last page and it has been translated as the $Altar\; Record\; of\; Confucius’s\; Conciliation$. This paper identifies the Chinese original among Ming-Qing religious scriptures of secret societies and suggests a new interpretation for the Tangut title. Connecting the title and the text with Chinese religious and intellectual traditions of the Song period also enables us to date the Chinese source text to the late eleventh or early twelfth century.
