If a painting of a tree was only the exact representation of the original, so that it looked just like the tree, there would be no reason for making it; we might as well look at the tree itself. But the painting, if it is of the right sort, gives something that neither a photograph nor a view of the tree conveys. It emphasizes something of character, quality, individuality. We are not lost in looking at thorns and defects; we catch a vision of the grandeur and beauty of a king of the forest.
And a beautiful world we live in, when it is possible, and when many other such things are possible, and not only possible, but done-- done, see you!-- under that sky there, every day.
