Antoine Dieu – Marriage of Louis of France, Duke of Burgundy, and Marie-Adelaide of Savoy, 7 December 1697 Château de Versailles

The picture has something of this: people, group, woman, religious, church, god, many, saint, man, wear, priest, worship, Renaissance, monk, royalty.
Perhaps it’s a painting of a group of people standing in front of a man in a blue suit and a woman in a red dress and a white dress.
