Why drawing and painting is important:
"For Da Vinci, drawing was his prime means of analyzing the phenomena of the living world. Painting was the synthesis. Analyzing in the way I use it here, however, is not ‘taking apart’ something observed or experienced, nor is synthesis ‘putting parts back together.’ Da Vinci’s method of analysis was by analogy. Rather than pick apart a phenomenon, separating what he perceived as its components, he created in a drawing a parallel world, an analog to reality. Working with analogs, he could emphasize the features of phenomena he considered most important. Da Vinci’s blobs—drawn masses of turbulent water or stormy air—are prime examples of his analogical method of analysis."
