What we have, I think, is a wonderfully intricate array of circles, all of them organized around two different foci. Despite my contempt for PowerPoint and my aversion to slide shows, I would have drawn this configuration for you, but I am not up to that, and you'll have to imagine it, either visually or otherwise. First we have works of art, and other objects of appreciation, and around each of them is the intimate circle of those who care for these things. But the auditors themselves are foci, each of them in turn, and each of them belongs to the circles of many objects. So we would have to make both the works and the appreciators centers of circles, and these will be overlapping, some- times entirely within one another, sometimes completely separate from one another, and there will be lenses and lunes galore.
