I remember that the afternoon shadows against the wooden furniture -- cabinets and chests of drawers -- at my uptown grandmother's house were like nothing at home. She had patterned gauze curtains, which we didn't, and the patterns cast their light shadows against the slightly tempered sunlight on the peaceful wood surfaces. The curtains would sway just a little, which would make the shadows seem not so much to move as to modulate their lightness, make the lightness feel even more essential, made the wood seem there to be the perfect surface for these modulations. It wasn't quite hypnotic, but it did make the whole room, not only the "visual room" (as Wittgenstein calls it) but the room around me, the windows and curtains and walls and the courtyard outside and the buildings around the courtyard and the sky, seem a single, calm, unhurried afternoon space, as unhurried as the modulations of the shadows on the smooth, seasoned wood.
