Opzoomer, Simon – Het laatste gebed van Johan van Oldenbarneveldt, 1840 - 1878 Rijksmuseum: part 1

The picture has something of this: people, opera, group, wear, woman, performance, room, theatre, music, man, theater, furniture, stage, seat, portrait, dancing, two.
Perhaps it’s a painting of a man holding a cane in front of a group of men in a room with a checkerboard on the floor and a chair in the foreground.
