Portrait of a knight of the order St John of Jerusalem Bernardo Strozzi (1581-1644)

The picture has something of this: people, wear, portrait, royalty, veil, man, sword, theater, outfit, woman, weapon, recreation, performance, lid, armor.
Perhaps it’s a close up of a painting of a man wearing a black and white outfit with a star on his chest and a cane in his left hand.
