Motion, Duration, Illumination

The next part of the "Survey" section begins to talk about Motion, Duration and Illumination. They all work together and the most traditional of the visual art is static, meaning to capture a moment in time. Illumination is depended upon the light source within that art. Artists have studied this light and how it creates shadows the way it falls on objects. Shanken uses the example of "Ecstasy of St. Theresa" (1647-52) where rays of sun would shine through a window above an alter. Understanding light in a piece of work is crucial and can make a significant change in how art is perceived.
