Drawn to symmetry
Why is architectural symmetry so satisfying? As Leonardo da Vinci’s famous drawing demonstrated, it reflects the human body, which has a right side and a left, a back and a front, the navel in the very center. Du Sautoy writes that the human mind seems constantly drawn to anything that embodies some aspect of symmetry. He observes that “[a]rtwork, architecture and music from ancient times to the present day play on the idea of things which mirror each other in interesting ways.” When we walk around a Baroque church, we experience many changing views, but when we walk down the main aisle—the line along which the mirror images of the left and right sides meet—we know that we are in a special relationship to our surroundings. And when we stand below the dome of the crossing, at the confluence of four symmetries, we know we have arrived.
