I have shown you what is wonderful. Come now and I will show you what is more wonderful. For I will show you these infinite spaces of the sky, and the glory of them, and the innumerable host of starry worlds, gathered up in a moment of time, within the tiny pupil of a human eye. It is wonderful that the heavens and the host of them should be so great; but that, being so great, they should be able to become so infinitely little,--this passes all wonder. The shepherd stretched upon the ground amid his sheep gazes up into the starry depths, and finds them wonderful; but never thinks how far more wonderful than the heavens which he beholds is himself beholding them. As he lies gazing, long lines of light, from planet and star and constellation, come stretching on through the infinite void spaces, to center on the lenses of his drowsy eye. Side by side, and all at once, yet never twisted or confused, these ten thousand rays of different light enter the little aperture in the center of the eye which we call the pupil. There they cross, in a point which has no dimensions, and separate again, and paint in microscopic miniature upon the little surface of the retina, behind the eyeball, the inverted facsimile of the visible heavens. There, in the ante-chamber of the brain, marches Orion, with his shining baldric and his jeweled sword; there glow Arcturus and Sirius, and the steadfast North Star; there pass the planets to and fro; and the far-off nebulæ are painted there with suffused and gentle radiance--all the heavens and the glory of them gathered in that slender filament of light, threaded through that tiny aperture, painted by their own rays upon that little patch of nervous network, apprehended, felt, known through and through by that finite human mind. How far stranger and sublimer a thing is this than the mere bulk of the worlds, or the mere chasms of void space in which they hang weltering!
