Lampi, Johann Baptist Elder – Portrait of Prince Grigory Alexandrovich Potemkin Tauride Hermitage ~ part 07

The picture has something of this: people, portrait, costume, woman, sword, fantasy, wear, helmet, armor, man, veil, warrior, wig, face, cape.
Perhaps it’s a close up of a painting of a man wearing a suit of armor and holding a helmet with a red sash around his neck and a red scarf.
