Unknown artist – Een ambassadeur op audiëntie bij sultan Ahmed III, 1737-1744 Rijksmuseum: part 3

The picture has something of this: people, home, room, furniture, group, seat, museum, indoors, wear, architecture, daylight, chair, veil, castle.
Perhaps it’s a painting of a group of people standing in front of a table in a room with red walls and a chandelier hanging from the ceiling.
