This small book for the first time fully tells the history of the famous Vatican copy of the Kazan Icon of the Mother of God. The author of the book, who was directly related to the return of this shrine to its homeland, examines different versions of the origin of the Vatican list of Russian icons, which mysteriously ended up in the West in the 40s of the twentieth century: first in London, then in San Francisco, later in Fatima, Portugal, finally in the 90s – in the personal chambers of the pope in the Vatican. The book contains unique documents, including correspondence with Patriarch Alexy II, shedding light on the long and fulfilled.
