Ukhtomsky, Konstantin Andreevich. Types of rooms of the New Hermitage. Voltaires library Hermitage ~ part 12

The picture has something of this: architecture, church, building, arch, cathedral, castle, indoors, monastery, religious, column, decoration, dome, turning point, library.
Perhaps it’s a painting of a room with bookshelves and a statue of a man standing in the middle of the room with a bookcase on either side.
