Light upon chaos, light, and yet more light; For--as I watched the planets--Venus, Mars, Appeared to wax and wane from month to month As though they moved, now near, now far, from earth. Earth could not be their centre. Was the sun Their sovran lord then, as Pythagoras held? Was this great earth, so 'stablished, so secure, A planet also? Did it also move Around the sun? If this were true, my friends, No revolution in this world's affairs, Not that blind maelstrom where imperial Rome Went down into the dark, could so engulf All that we thought we knew. We who believed In our own majesty, we who walked with gods As younger sons on this proud central stage, Round which the whole bright firmament revolved For our especial glory, must we creep Like ants upon our midget ball of dust Lost in immensity? I could not take That darkness lightly. I withheld my book For many a year, until I clearly saw, And Rome approved me--have they not brought it yet?-- That this tremendous music could not drown The still supernal music of the soul, Or quench the light that shone when Christ was born. For who, if one lost star could lead the kings To God's own Son, would shrink from following these To His eternal throne? This at the least We know, the soul of man can soar through heaven. It is our own wild wings that dwarf the world To nothingness beneath us. Let the soul Take courage, then. If its own thought be true, Not all the immensities of little minds Can ever quench its own celestial fire. No. This new night was needed, that the soul Might conquer its own kingdom and arise To its full stature. So, in face of death, I saw that I must speak the truth I knew.
