Attributed to Francesco Boschi – Portrait of Galileo Galilei, Astronomer Château de Versailles

The picture has something of this: people, mustache, elderly, portrait, facial hair, man, leader, scientist, poet, writer, beard, famous, eyeglasses, person.
Perhaps it’s a close up of a painting of a man with a long white beard and wearing a black shirt with a white collar and white ruffled collar.
