Cross Reference
For Euler discovered
early in the nineteenth century
That all patterns of universe
Can be resolved into three
Conceptual differentiations
lines, crossings, and areas–
Systems immediately divide universe
Into an outsideness
And an insideness
And a little bit of the universe
Which is the dividing system itself–
Which always consists
Of a constant relative abundance
Of the lines, crossings, and areas
In which
C + A = L + 2.
