When through the water's thickness I see the tiled bottom of the pool, I do not see it despite the water and the reflections; I see it through them and because of them. If there were no distortions, no ripples of sunlight, if it were without that flesh that I saw the geometry of the tiles, then I would cease to see it as it is and where it is—which is to say, beyond any identical, specific place. I cannot say that the water itself—the aqueous power, the syrupy and shimmering element—is in space; all this is not somewhere else either, but it is not in the pool. It inhabits it, is materialized there, yet it is not contained there; and if I lift my eyes toward the screen of cypresses where the web of reflections plays, I must recognize that the water visits it as well, or at least sends out to it its active, living essence. This inner animation, this radiation of the visible, is what the painter seeks beneath, the words depth, space, and color.
