Painting devotees and artist researcher's interested in poiesis - check out 'Mysteries of the Rectangle' by Siri Hustvedt.

"Hustvedt is concerned with the very act of looking and the limitless rewards to be gleaned from sustained, careful attention. Unlike film and books, which progress over time, “Painting is there all at once,” she writes, it is only with patience and repeated viewings that elusive meanings present themselves."
