This Christ Pantocrator icon, likely made in the workshop of the famous “Muscovite from Mster” V. O. Guryanov, is undoubtedly a masterpiece. Its revetment (O. F. Kurlyukov) is drawn for early Christian memorials, and is striking due to its surprising integrity and spiritual and emotional power. Fantastic folkloric birds — two-headed eagles or Sirin birds — are perched upon the enamel revetment of a small icon of Our Lady of Kazan. The festive Russian version of Art Nouveau is demonstrated by the revetment of the small icon of Our Lady of Czestochova, a rare depiction of the holy Polish personage officially recognized by the Russian Orthodox Church.
