“ For the machine meant the conquest of horizontal space. It also meant a sense of that space which few people had experienced before – the succession and superimposition of views, the unfolding of landscape in flickering surfaces as one was carried swiftly past it, and an exaggerated feeling of relative motion (the poplars nearby seeming to move faster than the church spire across the field) due to parallax. The view from the train was not the view from the horse. It compressed more motifs into the same time. Conversely, it left less time in which to dwell on any one thing. ”
