Roslin, Alexander – Portrait of Ivan Ivanovich Betsky in his dressing gown Hermitage ~ part 10

The picture has something of this: people, man, seat, furniture, two, elderly, portrait, woman, sit, room, wear, reclining, indoors, music.
Perhaps it’s a painting of a man sitting in a chair with his hand on his chin and his right hand resting his chin on his left side of the chair.
