Marie-Laetitia Ramolino (1750-1836) Francois Pascal Simon Gerard (1770-1837)

The picture has something of this: people, veil, Renaissance, woman, god, saint, aura, wear, man, cape, prayer, two, royalty.
Perhaps it’s a painting of a woman in a white dress sitting in a chair in front of a busturine and a table with a cloth on it.
