What follows is called a blackout poem. A kind of found poem, it requires a text of some kind, not poetry, and a felt tip marker. Essentially, you carve an original poem out of this pre-existing text, highlighting your chosen words, phrases, sentences, and blacking out or otherwise obscuring the rest. It becomes both a visual thing and a poem.
I chose the concluding passage from Poe’s “The Fall of the House of Usher.” My blackout is not all that attractive to look at, but I think I ended up with an interesting little poem. This is what it looks like:
and this is how it reads:
The Shadows
As if a spell
threw back ponderous jaws
without doors,
she remained,
trembling, moaning.
I found myself wild
and I turned for
the shadows.
While I gazed,
a fierce breath
burst my brain.
I saw the mighty walls,
the voice of
a thousand waters,
deep and dank.

Cool. I’ve done found poetry with my students before, but I like this visual idea.
I did this one with my kids today. They seemed to have fun with it. And I got a poem out of the deal, too.
