Space and light are the twin hallmarks of Modern architecture. Space and light were always a part of the experience of buildings, but by eliminating ornament and modulated surfaces, Modern architects brought them to the fore. This is what Hopper captures in this luminous painting, one of his last, painted when he was 81. This particular room, which belonged to the painter, is empty—or recently vacated—yet it does not feel abandoned. Was it Hopper's bedroom? When asked what he was after in the painting, he answered, "I'm after ME."
