Through the loupe or peepstone it's there: a mini-

dot of air
and, when light shines through
the object, the gletz is visible, via microscope, x-ray scope.
It's a flaw, diminishing
an object: when light,
unimpeded,
passes through it,
the object's brilliance
is most brilliant. A gletz affects
clarity, affects merit.
It's best if no gletz can be found at all.
The gletz's place matters - higher up: bad news,
lower: less-bad news.
They indicate fragility,
these breathless, cell-sized cells
where two inmates are locked
and each has a knife.
