Unknown Artist – De apostel Paulus, 1600 - 1699 Rijksmuseum: part 1

The picture has something of this: people, portrait, elderly, man, facial hair, mustache, leader, beard, bald, priest, veil, saint, prayer, god.
Perhaps it’s a close up of a painting of a man with a long white beard holding a cane and looking off to the side with a serious look on his face.
