This is the drawing transparently laid over the painting. While there are inaccuracies in my drawing, I think you can still start to see how the foreground shifts between two readings. One as a ground plane that we are looking down on, the small rock augments that view. And the second as a plane shifting up and in front of the picture plane, the spotted drapery helping us along. The next two drawings should clarify the two views.(-> #6)
