Artists have used the GOLDEN SECTION or Golden Mean since the ancient Greeks discovered it. Painters have used it to provide harmony and perfection in their work since the Italian Renaissance. It is worked out using Fibonacci numbers. (i.e.: 2:3, 3:5, 5:8, 8:13, etc.) These ratios can be found in nature and in the body. Most artists hide the geometric structure underneath the paint. My use of it is explicit and it is an essential part of the painting. It provides a structure within which to experiment. In this particular case I explored cubism.
