Another Example of using "3rd"s

I took this picture in Greece, in 1973. Notice how the man’s head takes up nearly two thirds of the frame and the two boys above him take up only one-third. Notice too that there are really only three objects in the picture for your eye to linger on.

Wikipedia gives a pretty cool description of this rule here, and they note the rule dates back to 1797, but I’ve also read it dates back to the ancient Greek mathematicians who developed a trigonometric formula that defined beauty (women like Jennifer Aniston with sharply defined triangular faces are considered to this day to be more beautiful than women with round faces).
