To which the author attaches at the end of the work a list of literature, which in itself will be of interest to lovers of information in cases of witches and sorcerers. The cases of Yakov Yarov, Katerina and Irina Ivanov, chamberlain Saltykov, fortune telling in the bedroom of Elizaveta Petrovna, as well as the texts of conspiracies and apostasy letters are mentioned in historical books, including the notes of Catherine the Great, and in the studies of modern scientists. However, the conclusions from them are absolute arbitrariness of the author.
