Lamps Johann (Sr.) – Portrait of Empress Catherine II with the allegorical figures of the Fortress and Truth. 1790-e 900 Classic russian paintings

The picture has something of this: people, woman, veil, portrait, Renaissance, wear, dress, seat, baroque, saint, opera, castle, baby, princess.
Perhaps it’s a painting of a woman in a blue and white dress standing in a room with red drapes and a statue of a man in the background.
