This is about art and about history, but it is not art history. Let's be foot loose and fancy free, and just follow our feet from one imaginary gallery to another, from one museum to another, to an astonishing building – a home here, a factory there. Without any boundaries of time or space, let's enjoy the work of creative people, one by one, asking ourselves how the font of human ingenuity is opened and nourished and fulfilled. The imagined galleries we visit will include those of Albrecht Dürer and Caspar David Friedrich, with others to be chosen as we go.
