This, you see, is another example of what we have already said, that the artist does not paint what he knows to be facts, but the appearances, as he sees them from the point where his eyes are--his “point of sight.” You remember how in an earlier chapter that artist represented, or rather suggested the cows in the distance by a few dabs. That was how he saw them from his point of sight. I could not tell you then, but you will understand now, that he was obeying the law of perspective, and was representing the cows as they appeared in their own proper plane of the scene. Do you remember that when he drew in their horns and tails and other details, they looked like toy cows? We can now see why. They contradicted their surroundings; they no longer were at home in their own plane; their plane was a good way off, but they were represented as if close to our eyes; and, as we saw how small they were, they seemed to us like toy cows.
