Portrait of Count Alexei Petrovich Bestuzhev-Ryumin in exile Артемий Николаевич Бутковский

The picture has something of this: people, portrait, facial hair, mustache, beard, man, leader, priest, elderly, monk, saint, lid, pope, veil.
Perhaps it’s a close up of a painting of a man with a long white beard and wearing a black coat with a white ruff on his left hand.
