Fragonard, Jean-Honore (1732 Grasse - 1806 Paris) – Portrait of Diderot Part 1 Louvre

The picture has something of this: people, Renaissance, saint, portrait, god, man, elderly, wear, baroque, baby, facial hair, book, spirituality, royalty, prayer.
Perhaps it’s a painting of a man sitting at a table with a piece of paper in his hand.
