Awakened, He Turns to the Wall (Cento) 

Then, everything slept.
Where were you before the day?

You see here the influence of inference,
whereby things might be seen in another light,

as if the trees were not indifferent, as if
a hand had suddenly erased a huge

blackboard, only, I thought there was
something even if I call it nothing,

like the river stretching out on its
deathbed. No one jumps off.
