Tintoretto (Jacopo di Giovanni Battista Robusti), Italian (active Venice), 1519-1594 – Self-Portrait Philadelphia Museum of Art

The picture has something of this: people, portrait, man, facial hair, mustache, wear, side view, music, writer, beard, profile, poet, scientist, leader, musician, pensive.
Perhaps it’s a close up of a painting of a man with a beard wearing a black shirt and looking to his left with a serious look on his face.
