Portrait of the Catholicos (Patriarch) of Georgia Anthony II Vladimir Borovikovsky (1757-1825)

The picture has something of this: cross, holy, god, Easter, church, saint, prayer, book, priest, Orthodox, gold, biblical, people, spirituality, religious, pope, belief, symbol.
Perhaps it’s a painting of a man with a beard wearing a white hat and holding a crucifix in one hand and a cross in the other hand.
