Perspective in Motion

For a marvelous example of the kind of scroll painting that Hockney described, take a look at this eighteenth-century rendering of "Along the River During the Qingming Festival," found in the National Palace Museum in Taipei, Taiwan.

At the museum's website you can find a description of the painting and its history along with an interactive view where you can zoom & scroll, while Wikipedia offers a full-size version of the same image. As the Wikipedia entry notes, the scroll is meant to be read  (or "travelled") from the right side to the left. It appears to my eye, as well, that most of the people in the painting are moving in that direction, too.

Take some time to make the journey--even on a little screen it's a remarkable experience.
