The article analyzes the material of the draft manuscript of F. M. Dostoevsky's novel "Demons", specifically, the pages containing the scene of Karmazinov reading his work "Merci". The draft manuscript of the novel "Demons" is a syntactically coherent text containing a large number of author's edits between the lines and in the margins. The analysis of the manuscript made it possible to identify inaccuracies in its reading by publishers that negatively affect the interpretation of the text. In addition, this analysis helped to correct these errors and accompany them with the necessary textual commentary, affecting, in particular, such problems as the establishment of the text, the identification and analysis of new discrepancies (variants) between the sources of the text, as well as text omissions in print. The textual part of the work is continued by the historical-literary and real commentary proposed in the article based on the newly discovered information about the features of the creation of the artistic concept of "Demons," explaining the significance of literary and historical motifs that are associated with ancient culture and history for the novel plot. In the process of analyzing handwritten and printed sources, literary and historical allusions were established, which the specified episode of the novel "Demons" contains. In addition, the article examined the historical subtext and symbolism of ancient motifs that were reflected in the scene of literary reading in "Demons," as well as the content of some historical sources (works by ancient authors on the history of Ancient Rome; lectures by T. N. Granovsky, who became the prototype of the hero of the novel, Stepan Trofimovich Verkhovensky). New information revealed during the study of the draft manuscript of "Demons" indicates, on the one hand, that the ancient "trace" played an important role in the development of the idea of this novel, on the other hand, the complexity of the novel's narrative structure.
