As I wander about Ham House helping to repair the unrepairable I am always impressed by the way that the 17th c architect contrived to allow plenty of natural light to flood in. Even the below-ground cellar and kitchen area is lit by sunlight. This painting is on the main stairs and the window faces east.
If "Freefalling" reads this..........this picture comes from the head. There's nothing in it about the gut. Keep up the enquiry, you are getting closer.
