One of the important concepts throughout art history has been that of the so-called golden rectangle or golden ratio, a set of proportions that has been found to be aesthetically pleasing and can be found on the human body itself. The golden ratio is 1:0.618, and essentially divides a composition into 1/3 and 2/3. The golden ratio was used extensively by classical architects in creating well-known buildings, such as the Parthenon in Athens, Greece. It was also used by painters such as Leonardo da Vinci, Seurat and Piet Mondarian in both figurative and abstract compositions.
