Suzanne Necker (1739-1794) Joseph Siffred Duplessis (1725-1802)

The picture has something of this: people, portrait, woman, saint, queen, god, Madonna, gold, veil, Renaissance, interior, royalty, book, sculpture, jewelry.
Perhaps it’s a portrait of a woman in a white dress with a large hairdow in a gold frame with a red and gold trim around her neck.
