Frenhofer is the tragic hero of the story, and all the danger and glamour are on his side. He literally loves his painting, and he goes insane when he realizes he has lost her. “Gillette, Or the Unknown Masterpiece” is a subversive story, because at first it seems Frenhofer’s passion is enviable, even if he took it too far. But Didi-Huberman is right: most of us, painters and spectators, have ended up siding with Poussin. Professionalism is safe, because its passions can be calculated.
