See! Their Verses Are Laid

See! Their verses are laid
as mosaic gold to gold
gold to lapis lazuli
white marble to porphyry
stone shouldering stone, the dice
polished alike, there is
no cement seen and no gap
between stones as the frieze strides
to the impending apse:
the rays of many glories
forced to its focus forming
a glory neither of stone
nor metal, neither of words
nor verses, but of the light
shining upon no substance;
a glory not made
for which all else was made.
