The article reveals the ways of studying the features of the core concepts of Russian cultural identity representation in the Russian art of the 16-17th centuries, considered in its continuous dynamic and dialectical development at the key stages of formation and transformation. The relevance of the study stems from the fact that among a significant number of works on the problems of Russian art of the late Middle Ages and the beginning of the New Time, there are no special scientific works in which this topic would be considered as the main one. It is particularly important to define what the fundamental (archetypal) grounds of cultural identity is, how it is transformed at a turning point of history.

The problems of the study of this phenomenon should be attributed to the number of contemporary world challenges. In Russia a considerable academic interest of cultural identity comprehension was initiated by a systemic crisis that erupted in the country in the last quarter of the twentieth century. A radical destruction of the ideological paradigm and the choice of the "pro-Western" vector of development affected all aspects of life of society and personality, thus arousing the associations with the Europeanization in the time of Peter's
