Vanishing Point

Which is the left-hand side of the word?
How does it move about in space?
Where does it throw its shadow
(and can a word cast shadow)?
How can it be observed from behind
or set against the recession of space?
I should like to render in poetry
the equivalent of perspective in painting.
To give a poem the depth of a rabbit
escaping through fields and make it
distant whilst already
it speeds away from the one who’s watching
and veers towards the frame
becoming smaller all the time
and never moving an inch.
The countryside observes
and disposes itself around the creature,
around a point that’s vanishing.
