Iconography and Legacy
The Orthodox tradition records Gregory as a fellow-laborer of Saint Alypius of the Caves, who is recognized as the first icon painter of Kievan Rus and a disciple of Greek iconographers from Constantinople. Saint Alypius is commemorated on August 17.
According to the "Accounts of the Holy Iconographers," a text written in the early eighteenth century, Gregory "painted many wonderworking icons throughout the Russian Land," and his relics remained incorrupt.
One account suggests Gregory may have been among the iconographers from Constantinople who came to Kiev to decorate the Great Church of the Dormition of the Most Holy Theotokos, describing him as a Byzantine. The sources, however, provide no definitive basis for the claim that he was an associate of Saint Alypius, and the exact dates of his life remain unknown.
Gregory is honored in the Ninth Ode of the Canon of the Service of the Synaxis of the Holy Iconographers.
