Portrait of Louis-Francoise de Bourbon (1673-1743), Mademoiselle de Nantes in Mourning Clothes Louis de Silvestre (1675-1760)

The picture has something of this: veil, people, woman, wear, dress, portrait, saint, god, Madonna, spirituality, church, cape, cross, man.
Perhaps it’s a painting of a woman in a white dress with a black and white cloak over her head.
