Reconstruct that rainbow in your head
For myself I get to choose from among
The one that flew over Dublin streets
Or another at Clairmont Road leaving Decatur
Or the one that hovered faintly double
Over spongy south Florida
Others fictional or less vivid of recall
But equally and productively schematic

Now you can begin to work the changes
Starting with the apex around which
The opposèd and theoretic ends might wibble wobble
And enjoy the fleeting pleasure
In a point of no time
During which the arc stiffens
Into a perfect disposition a perfect line

Pursuant to other fleeting perfections
In an operation that requires
But scanty details such that
Now the options are limitless
As they have been all along

The Romanesque arch expanding into vault
The wealth of spheres cylinders and conic sections
The interwoven textures of braids knots
And serpentine involutions
Diagrammatic representations of salt crystals
Polymers and proteins
Matte landscapes and sensitive portraiture
And foam of solar systems galaxies and universes
