The article introduces to the scientists an unpublished poem of the middle of the nineteenth century dedicated to the enlightener of the Komi region Stephen of Perm (died in 1396), who had created a new writing - the Old Perm alphabet (script) - in the course of Christianization of the local Finno-Ugric population. The analysis of the lengthy poetic text (about 1000 lines), written by an amateur poet, obviously a student of the local spiritual institution, leads to the conclusion that not only widely used he the local folklore tradition (at the time of writing of the poem yet unstudied), but was also familiar with the written monuments (“Zhitie Stefana Permskogo (The Life of Stephen of Perm)” written by his colleague Epiphanius the Wise in the end of the 14th - early 15th century, and its later editions, for example, the “Tale of Stephen of Perm” of the 18th century). The fact that the author of the poem was familiar with the monuments reflecting the ancient Komi written language is of special interest. Those monuments are the inscriptions on two icons of the 14th - 15th centuries, one of which is now lost. In addition, the text of the poem of Stephen of Perm and the baptism of the Komi-Zyrians was obviously influenced by the Russian poetry of the first half of the 19th century - the tales of A.S. Pushkin “The Dead Princess and the Seven Knights” and the tale of P.P. Yershov “Konyok-Gorbunok (The Humpbacked Horse)”.
