The main task of the author of the historical novel is to adequately recreate the spirit of the epoch. In the reconstruction of historical truth, Dumas follows the basic principles of the aesthetics of the historical novel of Sir Walter Scott’s tradition. At the same time, the most important features of his individual writing style include a thorough knowledge of historical factography, extensive use of memoirs and systematic attention to the XVII century. Historical thinking serves as a kind of criterion for the selection and critical reproduction of numerous and sometimes contradictory sources. As a result, the writer manages to create a truly reliable picture of life, way of life and customs of the epoch described by him.
