NICHOLAS OF CUSA, SAILING HOME

     
       Never suppose an inventing mind as source
       Of this idea nor for that mind compose
       A voluminous master folded in his fire.

 
He was on board ship, sailing from Byzantium
when the moment of illumination came, a flash
of light that staggered him (as happened to Paul
on the Damascus road): when he understood
there can be no ratio, no means of comparison,
no middle term, between the finite and the infinite.
Thus, since God is infinite, we have no means
of knowing Him (invisible, incommensurate); so,
as Paul says, If any man thinks he knows anything,
he has not yet known as he ought to know.
It follows then, for Nicholas (De Docta Ignorantia)
our proper study is, to understand our ignorance.

 
I think of him in Constantinople, looking up
into that limpid sphere, that massive cupola,
Hagia Sophia: gazing back at those gigantic eyes:
Christos Pantokrator, hovering there, magnificent
in lapis lazuli, translucent marble.  He would 
have known that, even then, all-conquering armies
of the Pasha were encroaching on the city gates;
had swept away, already, the last flimsy shreds 
of once-almighty Christian Rome – history itself 
grown incompatible with that triumphant
image glaring down.
                     I cannot know You
as You are.  But when I think of you
I think of Bruegel panoramas: there’s Mankind
(a little, furry, muddy, peasant thing – yet
at home upon the earth – its caretaker – self-
conscious, quick – inventive builder, gardener –
blind governor – your tarnished mirror);
and, as he painted in The Road to Calvary,
you hide amongst us, suffering servant, near
the center of our troubles: buried in the crowd:
one of the roughs (disguised, in camouflage, 
unknown).
