From
Leonard on Painting: "Of the ten function of the eye, all appertaining to painting
- Painting embraces all the ten functions of the eye; that is to say, darkness, light, body and colour, shape and location, distance and closeness, motions and rest. My little work will comprise an inter-weaving of these functions, reminding the painter of the rules and methods by which he may imitate with his art all these things — the works by which nature adorns the world."
