Pehr Axel Nyström (1793-1868) Erik Wahlbergson (1808-1865)

The picture has something of this: people, portrait, furniture, wear, seat, man, facial expression, leader, book bindings, indoors, chair, elderly, priest, writer, easel.
Perhaps it’s a painting of a man sitting at a desk with a book in his hand and a pen in his other hand.
