Portrait of a Marechal de France, probably Chretien-Louis de Montmorency-Luxembourg (1675-1746) Jean Marc Nattier

The picture has something of this: god, people, ancient, antique, sculpture, saint, Renaissance, armor, helmet, wear, spirituality, portrait, vintage, gold.
Perhaps it’s a close up of a painting of a person wearing a suit of armor and holding a piece of paper in one hand and a glove in the other hand.
