Some of the characters in this novel are real-life historical figures, but one should not look for historical authenticity in every episode and on every page of this work. Historical personalities in this novel are largely protagonists created by the author’s pen, chosen and appreciated by him, whether it be Prince Pavel Dmitriyevich Tsitsianov or the young Persian prince and heir to the throne Abbas Mirza Qajar. The historical flavour of this novel is a reflection of the author’s own meditative and emotional response to the process of getting acquainted with real historical facts, so the historical figures explored here are also his own fictional characters, created by his rich imagination.
