The purpose of the article is to present the handwritten collection of the Irkutsk archpriest Fortunat Ivanovich Petukhov (1789–1872), formed in the middle of the 19th century. The author has made an attempt 1) to reconstruct the composition of the manuscripts and documents of the collection, 2) to trace the ways of its formation, 3) to identify the features of the selection of manuscripts and to trace the degree of influence on the fate of the collection of the first presentation in the work by Moscow scholar N. P. Bocharov. Textual analysis of a number of works mentioned in the list has made it possible for other authors to attribute some of the texts presented by N. P. Bocharov as manuscripts of his collection, and not as the author’s works of Fr Fortunatus. We are talking about the well-known work of the Irkutsk local historian N. V. Semivsky, used for the autobiographical notes by F. I. Petukhov and as an integral part of other works by the archpriest, as well as about the manuscript of a much lesser-known work by another Irkutsk priest, Fr Nikifor Parnyakov. This gives reason to assume the possibility of a similar attribution of other works indicated by N. P. Bocharov with the name of F. I. Petukhov. Several manuscripts from the collection of F. I. Petukhov were published by the biographer as part of his book. The location of the collection of Archpriest Fortunatus Petukhov has not been found; the article suggests directions for searching for a possible repository – materials from the archival funds of Moscow monasteries, connected with the life and activities of people from Siberia – Zlatoust, Sretensky, etc., as well as searches for the personal archives of Fr Fortunatus’ descendants.
