Meeting of the Betrothed Couple and the Departure of the Pilgrims detail Vittore Carpaccio (c.1465-1526)

The picture has something of this: people, saint, group, Renaissance, veil, cross, aura, Mary, god, church, man, cape, woman, book.
Perhaps it’s a painting of a man shaking hands with a woman in a red dress and a man in a green dress and a woman in a red dress.
