A Lecture On The Cube

You take a piece of stone,
chisel it with blood,
grind it with Homer's eye,
burnish it with beams
until the cube comes out perfect.
Next you endlessly kiss the cube
with your mouth, with others' mouths,
and, most important, with infanta's mouth. .
Then you take a hammer
and suddenly knock a corner off.
All, indeed absolutely all will say
what a perfect cube this would have been
if not for the broken corner
