Portrait of Johan Amos Comenius Rembrandt Harmenszoon Van Rijn (1606-1669)

The picture has something of this: people, portrait, facial hair, man, wear, scientist, royalty, mustache, Renaissance, engraving, writer, monarch, music, cape.
Perhaps it’s a painting of a man with a beard and a long white beard sitting in a chair with his hands folded over his chest and looking off to the side.
