What does it show? This shows the three stages of the picture.

1. The first stage of the picture is that plan which, before bringing on the canvas, the artist had designed, the artist had planned;
2. and the other aspect is that action of producing that picture which went as changes, right and wrong and right and wrong, and so on it went;
3. and the third aspect is the completion of that plan, the completion of that picture which stood quite different from the plan first conceived.
