This abridged 1810 edition of the Mandarin Chinese catechesis "Conversation of the Angels" by the Jesuit Francesco Brancati (1607-1671) was compiled by Fr Iakinf with chapter two taken from another Jesuit Andre-Jean Lubelli (1610-1683) published under various titles (1788, 1845), and edited to conform to Orthodox Christian teaching when Fr Iakinf was head of the ninth Russian Ecclesiastical Mission in China (1807-1821).
