Kalmytskaya chapel. 1869-1870 Vasily Vereshchagin (1842-1904)

The picture has something of this: people, furniture, tapestry, group, temple, seat, reclining, monastery, position, indoors, room, throne, kneeling.
Perhaps it’s a painting of a group of people sitting in a room with rugs on the floor and paintings on the walls of the room.
