Moeyaert, Nicolaes – Mooy-Aal en haar aanbidders, 1630-1640 Rijksmuseum: part 1

The picture has something of this: people, group, wear, woman, lid, man, performance, portrait, son, music, veil, theater, outfit, theatre, musician, recreation.
Perhaps it’s a group of people standing next to each other in front of a painting of a man in a black hat and a woman in a white dress.
