Portrait of Nikifor Artemyevich Sezemov Dmitry Levitsky (Levitzky) (1735-1822)

The picture has something of this: people, facial hair, portrait, Renaissance, saint, man, mustache, elderly, leader, veil, cape, god.
Perhaps it’s a close up of a painting of a man with a beard wearing a robe and holding a paper in his right hand and a book in his left hand.
