Ponte Vecchio, Florence

Stacked windows shrinking along a bridge

1883, etching: the houses stacked on the Ponte Vecchio, their windows shrinking along the span at a constructed rate, the arches below, reflections in the Arno. The dividing-bays lesson at its most visible, and a window-as-void lesson repeated fifty times.
