Portrait of Robert Arnauld d-Andilly Philippe De Champaigne (1602-1674)

The picture has something of this: people, portrait, elderly, leader, wear, man, writer, administration, music, facial expression, politician, side view, musician, chair, outfit, outerwear, menswear.
Perhaps it’s a close up of a painting of a man wearing a black coat and holding a cane in one hand and wearing a hat in the other hand.
