Eriksen, Virgilius. Portrait of Caspar von Salderna Hermitage ~ part 13

The picture has something of this: people, portrait, wear, veil, leader, royalty, necklace, woman, lid, side view, facial expression, monarch, man, outerwear.
Perhaps it’s a painting of a man with white hair wearing a blue coat and a red and blue sash around his neck and a gold chain.
