From the French window I walked out under a kind of pergola covered in part by a climbing rose tree, in part by laths, one inch wide with half an inch of space between them. The sun was shining and the shadows of the laths made a zebra-like pattern on the ground and across the seat and back of a garden chair, which was standing at this end of the pergola. That chair -shall I ever forget it? Where the shadows fell on the canvas upholstery, stripes of a deep but glowing indigo alternated with stripes of incandescence so intensely bright that it was hard to believe that they could be made of anything but blue fire. For what seemed an immensely long time I gazed without knowing, even without wishing to know, what it was that confronted me. At any other time I would have seen a chair barred with alternate light and shade. Today the percept had swallowed up the concept. I was so completely absorbed in looking, so thunderstruck by what I actually saw, that I could not be aware of anything else. Garden furniture, laths, sunlight, shadow - these were no more than names and notions, mere verbalizations, for utilitarian or scientific purposes, after the event. The event was this succession of azure furnace doors separated by gulfs of unfathomable gentian. It was inexpressibly wonderful, wonderful to the point, almost, of being terrifying. And suddenly I had an inkling of what it must feel like to be mad. Schizophrenia has its heavens as well as its hells and purgatories. I remember what an old friend, dead these many years, told me about his mad wife. One day in the early stages of the disease, when she still had her lucid intervals he had gone to talk to her about their children. She listened for a time, and then cut him short. How could he bear to waste his time on a couple of absent children, when all that really mattered, here and now, was the unspeakable beauty of the patterns he made, in this brown tweed jacket, every time he moved his arms? Alas, this Paradise of cleansed perception, of pure one-sided contemplation, was not to endure. The blissful intermissions became rarer, became briefer, until finally there were no more of them; there was only horror.
