The second is an image. In three-quarter profile, carved massively out of light and shade, a face towers over the commuters who wait, stunted, beneath. It is only an advertising photograph pasted on a billboard in a railway station, but to my mind's eye it has the impassive grandeur of long-forgotten queens and deities carved into rock faces by ancient civilizations. To contemplate the exquisite arc of the eye; the broad, smooth sweep of the cheekbones; the impeccable line and proportions of the nose, is to marvel that the randomness of human variation can produce something so supernaturally perfect as this. Such bones, discovered by the archaeologists of the future, would seem an artifact, a product not of blunt-tooled nature but of the very peak of artistic endeavor.

As if this extravagant beauty were not enough, there are the eyes. Intensified by some photographic sleight of hand to an inhuman green, the green of glass in a church window, or of emeralds or of boiled sweets, they gaze out over the heads of the commuters with perfect inexpression. I can't say whether the other travelers that day felt the same way as I about the picture; they had read the books, so they may have had a different perspective on things. But for me, looking into the large green eyes, I could not help being reminded of that commonplace expression about the eyes being the gateway to the soul. This woman, I remember thinking, as I gazed at her green, unseeing eyes, does not have a soul.
