In addition to this being wonderful visually, this photograph also makes me wonder about the wisdom of putting a window in the rock wall so close to the well, where water gatherers might more easily be picked off by an enemy. But putting aside any practical conjecture on my part, I find this one to be nicely framed and perfectly exposed. My favorite part is the sheen of the rock on the interior of the window itself. Guessing by the angle of the shadows, this shot probably would have been impossible in another few minutes due to glare.
