Vanmour, Jean Baptiste – Ambassadeur Cornelis Calkoen op audiëntie bij sultan Ahmed III, 14 september 1727, 1727-09-14-1737 Rijksmuseum: part 3

The picture has something of this: people, group, wear, many, veil, man, woman, sculpture, home, royalty, furniture, leader, museum, room, daylight, outfit.
Perhaps it’s a painting of a group of people dressed in medieval clothing standing in a room with a red wall and a large mirror in the middle of the room.
