I’m thinking about the famous artist Henry Moore exploring positive and negative space.
In my imagination, might he have taken up a new kind of sculpting within the parameters required of dry stone walling? The shape and contours of his iconic human reclining figures would be defined by the spaces between the stones making up the main figure, and the surrounding recessed stones in the wall. It’s Moore or less a conversation between what’s there and what’s not.
Sometimes we learn a lot more about something if we stop saying "it is what it is", and realize that really, "it is what it isn't"!
