Among the memorable names imprinted on the tablets of Russian history and literature, the name of Simeon Polotsky occupies a special place. One can be reprehensible to the grandeur of his poetry, to loyalty, which sometimes reaches pettiness, but one cannot take away from the hero of the documentary narrative Boris Kostin's devotion to serving the Word of God. Inspired sermons by Simeon Polotsky seem to connect the 17th century with the present time to this day with an invisible clutch. The enlightener and thinker, playwright and educator of the children of Tsar Alexei Mikhailovich - this is how Simeon Polotsky is presented on the pages of the book, who claimed that "Peace is a book."
