Comprehensive study of 12th century wall painting fragments from the St. George Cathedral of the Yuryev Monastery in Veliky Novgorod (Russia) using complementary physico-chemical methods

Abstract

A total of 7 complementary methods have been applied to investigate unique pre-Mongolian 12th century wall paintings from the St. George Cathedral of the Yuriev Monastery in Veliky Novgorod, Russia. Both archaeological samples from the main space of the Cathedral and fragments in situ in the stairs tower of the Cathedral were studied. For the first time in Russia, sensitive neutron methods were used to study the elemental composition of pigments and plasters—neutron activation analysis and prompt gamma activation analysis. This research made it possible to determine elemental and mineral composition of the pigments and plasters used during creation of wall paintings; identify the technique of paintings; make assumptions about the different time of the paintings creation in the main space of the Cathedral and in its stairs tower; as well as reconstruct the presumable original view of the painting of the St. George figure. The discovery of the expensive lazurite pigment attested to the high status of the ktetor of the Cathedral’s murals. The obtained data were compared with Byzantine and Italian paintings of the same period churches.
