Visiting Artist Lecture: James Siena

I attended the Painting and Printmaking departments visiting artist lecture: James Siena
Siena's paintings deal with line, pattern, rule, breaking rule, natural math, color. His designs range from many different workings of choosing a "rule" or equation/pattern to follow in order to create his compostitions. One major rule of Siena's was that lines could never touch, yet periodically he will, for some reason unknown to him, break his own rule. Perhaps by breaking his own rule he is subconciously commenting on the nature of nature. Siena also likes to repaint paintings or do alterations to and create numerous paintings with the same "rules" yet he would create a different variation to the same idea. Siena mentioned a few times that he was "existentialist" in his beliefs and I couldn't help but see the mathematical equations repeated in each work, for example the fibonacci sequence and the nautulus spiral is all I can see when looking at the painting of the rectangles devided into 1/8ths, or even one painting becomes the honeycomb of beehives, and for me it all speaks very much so of the mathematical patterns found in nature such as DNA, etc. which also speaks to me of Existentialism, down to each paintings core.
