Yestereven, erasure marked typographically, as with Carson and Schwerner, giving a feel of fidelity, though that’s often mock. Also, erasure as palimpsest, as in Bervin’s Nets, the source poem receding into the page but not altogether invisible.
The maybe most austere mode is just to leave the page untouched in its white or creamy presentness. That’s Ronald Johnson’s approach in Radi Os, his seminal erasure of Milton’s Paradise Lost —
If austere is one end of a spectrum, and illuminative the other, somewhere in the middle’s any practice that retains the erasure marks, making what art of them they propose. Can find a precursor to that in this page from Johnson’s draft copy of Paradise Lost —
It’s a question I’ve messed with some in Overject, erasures I’ve tried out of a minor Anglo-Saxon poem sequence variously called “Maxims” or “Gnomic Verses” or (by me) “Proverbs.” Here I work up the redaction marks to make some funny (and some not-so-funny) faces.
At the illuminative end of the spectrum (both ends and all middles presided over majestically by Wm. Blake) must for sure be Tom Phillips’s A Humument.
