....Sum pius Petrus. [Vergil, Aeneid]
The Salisbury classroom.
The stones sum 1s, and leaning 1s,
and pi, in massive stone, sublime
in the incomprehensible mathematics
of an earlier law of addition.
'Now,' the stones say, all together,
Glooming over their class
Of gawping humans, 'add it.
Be quick, or this flint knife will
Take away your beating heart
Is found not counting up
But counting in, towards the I-AM
The I, the I, the rough-squared M.
