Eggs are said to have both positive charge and negative charges, the negative is in the yolk and the positive is in the white. While reflecting on this I was struck with, egg tempera uses only the negative aspect of the egg to paint divine image, hoping we might call the image positive. Together, the positive and negative make a “perfect” teaching. In quotes because I am only suggesting what we imagine could be perfect. More important is the symbolism represented in the idea. I love eggs and I love icons.
