Introduction In Russia previously only one art object has been dated dendrochronologically—it was a Dexiokratusa icon from Velikiy Dendrochronological dating is usually the only method of pre- Novgorod (Voronin et al., 2015). There are two main reasons for cisely dating unsigned art objects made on or of wood. Whereas this poor state of such research: (1) sparse dendrochronological numerous studies are dedicated to this topic in Europe (e.g., Bauch network mainly representing coniferous species (mainly pine and and Eckstein, 1970; Lavier and Lambert, 1996; Kuniholm, 2000; spruce) and (2) problems with getting permission for the analyses Wazny, 2002), there are quite few of them in Russia (here we take of art objects in museums and galleries. only the European part of the country). In Eastern Europe several The three icons—“Mother of God with the Child, Jerusalem type” works were carried out on radiocarbon dating (Kovalyukh et al., (MOG), “St. Nicholas of Myra in Lycia with scenes of his life” (NIC) 2001) and on dendrochronological dating (Krapiec˛ and Barniak, and “St. George and the Dragon miracle” (GEO) have been selected 2007) of icons painted between the 12th and 19th century. for the analysis because they are painted on coniferous panels, they Up to now, medieval Russian icons were mostly studied by represent one region—North-West (NW) of European Russia (ER), art historians and chemistry technologists, but they usually date which has a dense dendrochronological network (Fig. 1) and a con- these objects on the basis of an empirical relative chronology.
