The book by the famous Russian art historian Nikodim Pavlovich Kondakov (1844-1925) is a brilliant work on the artistic features of Russian icon painting. Thanks to the efforts of Kondakov and other scientists and artists, who in the first half of the 20th century revealed to the world the depths of icon painting, today the Russian icon is considered one of the unique types of art and the only one that can rightfully be called divinely inspired.
