Let me tell you a little experience of my own. Though I am not an artist, I have often made drawings. One day I was enlarging a piece of ornament, in which there were scrolls of acanthus leaves; big cabbagy sort of leaves, with a curving spine and crinkly edges. The chief point was to get fine winding lines into the curves. For a long time I imitated the copy as well as I could, when suddenly I seemed to feel within me just how the curve should go. It was not a matter of seeing the copy, but of feeling the actual growth in my brain. And lo! a miracle, for one moment my hand was able to do what my brain prompted. That leaf actually grew under my hand. I could feel it growing. And of course that was the best bit of the whole drawing. The rest was mechanical; this bit really lived. Well, in my case that was a miracle and has never been repeated. But in that moment I learned two things--firstly, what must be the joy of an artist in the act of creation; and, secondly, that an artist’s line may be a living growth; and, in the case of really fine draughtsmen, always is.
