Pieneman, Jan Willem – Jacob Simonsz de Rijk bewerkstelligt bij de Spaanse gouverneur-generaal Requesens de vrijlating van Marnix van Sint Aldegonde, 1805-1808 Rijksmuseum: part 2

The picture has something of this: people, group, child, woman, wear, man, many, son, family, room, boy, five, group together, baby, motion, music.
Perhaps it’s a group of people standing next to each other in front of a painting of a man in a red suit and a woman in a white dress.
