Portrait of Abbe Esten Zinaida Serebryakova (1884-1967)

The picture has something of this: people, portrait, man, wear, outerwear, veil, facial hair, facial expression, reclining, music, jacket, pants, lid, leader, musician, furniture.
Perhaps it’s a painting of a man in a black shirt sitting in front of a chair with a white curtain behind him and a cross on the wall behind him.
