The Meeting at Neuhaus in Bohemia, 24th May 1737 Louis de Silvestre (1675-1760)

The picture has something of this: people, group, church, saint, book, woman, veil, Mary, Renaissance, ceremony, virgin, priest, many, man, wear.
Perhaps it’s a painting of a large group of people in formal dress standing in front of a crowd of men and women, all looking at each other people.
