Regters, Tibout – De Amsterdamse doopsgezinde familie Brak, 1752 Rijksmuseum: part 3

The picture has something of this: people, group, woman, wear, furniture, man, leader, seat, position, royalty, kneeling, many, monarch, sit.
Perhaps it’s a painting of a group of people posing for a picture in front of a table with a book on it and two children sitting on the floor.
