The book presents the diary of a person suffering from coronavirus infection and forced to spend 40 days in complete isolation. The author is a hieromonk of the Russian Orthodox Church, serving in a crowded parish in the very center of Moscow, an Italian by birth and a literary critic and historian by secular education. The book is a verbal portrait of him. It includes a variety of texts about faith, suffering and the meaning of existence, about Orthodoxy in the modern world and the Church in post-Soviet Russia, about historical disputes between Catholics and Orthodox Christians and collisions between Russia and the West. At the same time, the author talks a lot about Italian and Russian literature, cinema, art, world history and culture. In the book, the perspective and angle of observation of the author is very important: thanks to the uniqueness of the life path of the Italian Orthodox hieromonk and his erudition, we are presented with an extraordinary opportunity to look at Orthodoxy and Russia simultaneously from the outside and from the inside. The book will be of interest to a wide range of readers.
