Furthermore A. Yu. Mitrofanov also examines in detail the fragments of the work of Anna Komnena, which were dedicated to the phenomenon of so called Byzantine imposture. According to A. Yu. Mitrofanov, one of the first examples of Byzantine imposture arrived at the end of the reign of Emperor Leo III the Isaurian (717–741) with the appearance of the impostor Pseudo-Tiberius Pergamenus, who declared himself the surviving son of Emperor Justinian II Rhinotmetos (685–695, 705–711). The name of Justinian’s II son was Tiberius and he has been murdered as a child of eleven years old in 711 in front of his grandmother – Empress Anastasia. Drawing on the research of Paul Speck and others[9], A. Yu. Mitrofanov suggests that the hypothetical story of the “Life of Leo” (*Vita Leonis) about the murder of Tiberius, which had been reproduced in the “Chronography” of Theophanes the Confessor, probably has been interpolated during the rebellion of Pseudo-Tiberius Pergamenus to uncover him.

According to sources of the “dossier” of George Synkellos, one of them is, for example, a hypothetical “History of Leo and Constantine” (*HL), which had been followed by Theophanes the Confessor in the narrative of Byzantine history after the year 718, Pseudo-Tiberius Pergamenus received the support of the Umayyad Caliph Hisham Ibn Abdal-Malik (723–743)[10]. Such reliance on external enemies of the Byzantine Empire was characteristic of later Byzantine impostors, to whom Anna Komnena was contemporary. That is why Mitrofanov examines in detail the fragments of Anna Komnena on the impostors Pseudo-Michael and Pseudo-Diogenes I Furthermore the Author mentions out of the Russian Chronicles the rebellion of the impostor Pseudo-Diogenes II “Devgenevich” and the rebellion of his son, the Pseudo-Prince Vasilko Leonovich.

Pseudo-Michael was a protégé of the Normans and Robert Guiscard personally; Pseudo-Diogenes I relied on the help of the Cuman Khan Tugorkan, while Devgenevich and Pseudo-Prince Vasilko enjoyed the support and official recognition of the Grand Duke of Kiev Vladimir Monomakh (1113–1125).

Vladimir Monomakh even related himself to the impostor Devgenevich by marring his daughter Maritsa to him. Their son was the impostor Pseudo-Prince Vasilko. On the basis of these undeniable historical facts, proved by A. Yu. Mitrofanov, the phenomenon of Byzantine imposture, which had been largely documented and described by Anna Komnena and other Byzantine historians, mentioned by the Author, proves to be an old and well known strategy of impostors on the byzantine imperial throne. This phenomenon is repeated by Russian political culture. This circumstance manifested itself many centuries later during the Time of Troubles (1605-1613) and during the reign of Empress Catherine the Great (1762–1796), and then influenced the formation of the phenomenon of Soviet leaders and Soviet totalitarianism.
