Portrait of a Man (fragment) Tintoretto (Jacopo Robusti) (1518-1594)

The picture has something of this: people, facial hair, portrait, mustache, man, leader, elderly, beard, side view, wear, writer, scientist, poet, philosopher.
Perhaps it’s a close up of a painting of a man with a beard and wearing a black suit with a white collar and a black shirt with a black collar.
