Portrait of John Locke (1632-1704) Sir Godfrey Kneller (1646-1723)

The picture has something of this: people, portrait, engraving, scientist, man, writer, cravat, leader, wear, poet, philosopher, facial hair, politician, outerwear.
Perhaps it’s a close up of a painting of a man in a black suit and white hair and wearing a black shawl and a white collared shirt.
