Among the memorable names imprinted on the tablets of Russian history and literature, the name of Simeon of Polotsk occupies a special place. One can be reprehensible about the grandiloquence of his poetry, about his loyalty, which sometimes reaches the point of pettiness, but one cannot take away from the hero of the documentary narration Boris Kostin his devotion to serving the Word of God. The inspired sermons of Simeon of Polotsk seem to connect the 17th century with the present as if by an invisible link. Enlightener and thinker, playwright and teacher of the children of Tsar Alexei Mikhailovich - this is how Simeon of Polotsk is presented on the pages of the book, who claimed that “The world is a book.”
