it was not as simple as that. On his near, relaxed side his fist was clenched and the hardness of his knuckles recalled thehard line of his ribs on the other side – like a cairn on the hills recalling the cliffs.
I now began to see the white surface of the paper, on which I was going to draw, in a different way. From being a clean flat page it became an empty space. Its whiteness became an area of limitless, opaque light, possible to move through but not to see through. I knew that when I drew a line on it – or
through
it – I should have to control the line, not like the driver of a car, on one plane: but like a pilot in the air; movement in all three dimensions being possible.
Yet, when I made a mark, somewhere beneath the near ribs, the nature of the page changed again. The area of opaque light suddenly ceased to be limitless. The whole page was changed by what I had drawn just as the water in a glass tank is changed immediately you put a fish in it. It is then only the fish that you look at. The water merely becomes the condition of its life and the area in which it can swim.
Then, when I crossed the body to mark the outline of the far shoulder, yet another change occurred. It was not simply like putting another fish into the tank. The second line altered the nature of the first. Whereas before the first line had been aimless, now its meaning was fixed and made certain by the second line. Together they held down the edges of the area between them, and the area, straining under the force which had once given the whole page the potentiality of depth, heaved itself up into a suggestion of solid form. The drawing had begun.
The third dimension, the solidity of the chair, the body, the tree, is, at least as far as our senses are concerned, the very proof of our existence. It constitutes the difference between the word and the world. As I looked at the model I marvelled at the simple fact that he
was
solid, that he occupied space, that he was more than the sum total of ten thousand visions of him from ten thousand different viewpoints. In my drawing, which was inevitably a vision from just one point of view, I hoped eventually to imply this limitless number of other facets. But now it was simply a question of building and refining forms until their tensions began to be like those I could see in the model. It would of course be easy by some mistaken over-emphasis to burst the whole thing like a balloon; or it might collapse like too-thin clay on a potter’s wheel; or it might become irrevocably misshapen and lose its centre of gravity. Nevertheless, the thing was there. The infinite, opaque possibilities of the blank page had been made particular and lucid. My task now was to coordinate and measure: not to measure by inches as one might measure an ounce of sultanas by counting them, but to measure by rhythm, mass and displacement: to gauge distances and angles as a bird flying through a trellis of branches; to visualize the ground plan like an architect; to feel the pressure of my lines and scribbles towards the uttermost surface ofthe paper, as a sailor feels the slackness or tautness of his sail in order to tack close or far from the surface of the wind.
I judged the height of the ear in relation to the eyes, the angles of the crooked triangle of the two nipples and the navel, the lateral lines of the shoulders and hips – sloping towards each other so that they would eventually meet, the relative position of the knuckles of the far hand directly above the toes of the far foot. I looked, however, not only for these linear proportions, the angles and lengths of these imaginary pieces of string stretched from one point to another, but also for the relationships of planes, of receding and advancing surfaces.
Just as looking over the haphazard roofs of an unplanned city you find identical angles of recession in the gables and dormer-windows of quite different houses – so that if you extended any particular plane
