explains to himself the effect of light upon a given object; but there is no such thing as a line in nature, where all things are rounded and full. It is only in modelling that we really draw, in other words, that we detach things from their surroundings and put them in their due relief. The proper distribution of light can alone reveal the whole body. For this reason I do not sharply define lineaments; I diffuse about their outline a haze of warm, light half-tints, so that I defy any one to place a finger on the exact spot where the parts join the groundwork of the picture. If seen near by this sort of work has a woolly effect, and is wanting in nicety and precision; but go a few steps off and the parts fall into place; they take their proper form and detach themselves, the body turns, the limbs stand out, we feel the air circulating around them.
"Nevertheless," he continued sadly, "I am not satisfied; there are moments when I have my doubts. Perhaps it would be better not to sketch a single line. I ask myself if I ought not to grasp the figure first by its highest lights, and then work down to the darker portions. Is not that the method of the sun, divine painter of the universe? O Nature, Nature! who has ever caught thee in thy flights? Alas! the heights of knowledge, like the depths of ignorance, lead to unbelief. I doubt my work."
