The book was written to help teachers of the Fundamentals of Orthodox Culture. N. A. Yakovleva is a teacher with half a century of teaching experience at school and university, the author of dozens of books and articles on the history of Russian art and aesthetic education. Based on his spiritual and practical experience, the author not only talks about the fact that there is a Russian temple, an icon and an iconostasis as works of art, but tries to bring to the teacher's consciousness their sacred meaning as phenomena, the spiritual core of which is clothed in a special artistic form. The book is easy to read because it is written in a lively, understandable, emotionally colored language.
