Art in a different language
Art can come to you in many different styles, capacity and understanding. We all see and understand it differently, which is a good thing. The freedom of looking and interpreting is a universal thing.
In this specific image, taken in Saint-Tropez, I see a posible ancient language, long gone and no one left that understands it. That is the beauty of imagination, it can be what ever you want, everything you make of it is your truth, within your world and your context.
Indeed, looks like an ancient kind a language.
