The article is devoted to the research and restoration of the icon “The Apparition of the Holy First-Faithful Apostles Peter and Paul to the reverend Peter the Tsarevich of Horde” of the end of the XVII century from the collection of the State Rostov-Yaroslavl Architectural and Art Museum-Reserve. The article presents a brief history of the life of the monument as part of the iconostasis of the Dormition Cathedral of the Rostov Kremlin, including the period of its creation, location at different times, as well as a description of the rare iconography. Information is provided on various introductions into the structure of the monument (consequences of unprofessional reinforcement, renovation inserts in levkas losses, work with the base of the icon). Special attention is paid to the complex of physical and chemical research. The article reflects the process of selecting the optimal restoration techniques in case of the factors complicating the strengthening: bio-damage on the reverse and front sides of the icon, unstable condition of the base due to fluctuations in temperature and humidity conditions, destruction and weakening of wood, mold-affected levkas, numerous damaged areas of the levkas and paint layer. The work was carried out to eliminate the consequences of past unprofessional restoration interventions in the form of levkas overlaid on the paint layer, displaced and inverted fragments of the levkas with the paint layer, haphazardly glued without conforming to the pattern, pressed in and sunk into the levkas. A description of the restoration processes carried out, including the materials used, and the results of the restoration process are given.

Biological damage, conservation of the base of the icon, displaced fragments of levkas with a colorful layer, icon, previous restoration interventions, reinforcement, research, the Dormition Cathedral of the Rostov kremlin.
