On the last sheet there are imprints: "The type was published in Warsaw in the printing house of E.K.V. King Polsky and the Grand Duke of Lithuania. In the summer from the creation of the world 7293. With a translation printed in Moscow: in the summer of 7161 " . At the same time, "printing houses of E.K.V. King Polsky" are false outputs. In fact, the book is printed in the printing house of Peter Dufort.
Books for Russian Old Believers in Warsaw were printed by the merchant Mikhail Grigoryevich Solovyov. In 1784, he moved from Supraśl, where he kept an Old Believer printing house, together with his assistant A. Czerniawski, to Warsaw, where he concluded an agreement with the owner of one of the printing houses - the printer and bookseller Peter Dufourt (1730-1797), a native of Paris. The publication of Old Believer books in Warsaw was carried out until 1788 and was interrupted in connection with the departure to another printing house of A. Cherniavsky, who went to work in the Free Printing House of J. Potocki. From 1785 to 1788, six editions were published in Warsaw, the printing of which used ornaments brought by M.G. Solovyov from Supraśl, and a font cast by his order in Warsaw by the master P. Zawadski.
