Portrait of Count Grigory Grigorievich Orlov in armor Fyodor Rokotov (1735-1808)

The picture has something of this: people, portrait, man, wear, cape, sword, sash, veil, Renaissance, lid, armor, costume, monarch, son.
Perhaps it’s a close up of a painting of a man in a suit with a red sash around his neck and a helmet on his left side of his head.
