Nicodemus Tessin d.y., (1654-1728) * Georg Desmarees (1697-1776)

The picture has something of this: people, Renaissance, saint, portrait, wear, man, cape, baroque, woman, veil, god, son, two, church, baby.
Perhaps it’s a painting of a man with white hair wearing a red and white outfit and holding his hands out to the side of his body, sitting in a chair.
