The book “The Wonderful Life of Joseph Balsamo, Count Cagliostro” (1919) was supposed to become part of the series of historical monographs “The New Plutarch” conceived but not implemented by M. A. Kuzmin (1875–1936). It tells the story of the life and adventures of Count Cagliostro (1743–1791), an adventurer and hypnotist who posed as a wizard and magician. The text of the book was translated from the original language using an artificial intelligence program. For the most part, the translation of the text is of very high quality, but in some cases, due to the imperfection of the technology, there may be incorrect phrase translations in the text, as well as single words and expressions may not be translated.
