[Unidentified]

His head is a little interior of grey mirrors.
Each gesture flees immediately down an alley
Of diminishing perspectives, and its significance
Drains like water out the hole at the far end.
He lives without privacy in a lidless room,
The bald slots of his eyes stiffened wide-open
On the incessant heat-lightning flicker of situations.

Nightlong, in the granite yard, invisible cats
Have been howling like women, or damaged instruments.
Already he can feel daylight, his white disease,
Creeping up with her hatful of trivial repetitions.
The city is a map of cheerful twitters now,
And everywhere people, eyes mica-silver and blank,
Are riding to work in rows, as if recently brainwashed.
