"An eye for an eye, and a tooth for a tooth." Sounds very hard-nose doesn't it? It seems like an ancient recipe for harshness that modern society has long ago outgrown. Not so. Few passages in the Bible are as badly misunderstood as this one. The "eye for an eye" maxim is not about harshness; it's about proportional retribution.
	Light rays are focussed through the transparent cornea and lens upon the retina. The central point for image focus (the visual axis) in the human retina is the fovea. Here a maximally focussed image initiates resolution of the finest detail and direct transmission of that detail to the brain for the higher operations needed for perception.
	They say that the eyes are the window to the soul. Who are we to say otherwise. In ancient beliefs it was thought that the mandorla holds the geometric key to the crossing of two worlds, being the product of two overlapping circles (a triangle being made when you cross three).
