Ronald Johnson's radi os (Flood Editions 2005, Sand Dollar Press 1977), an erasure of the first four books of Milton's Paradise Lost. Johnson explains, "It uses an 1892 edition in which I omit most of the text to create a Blakeian visual page and a new Orphic text of my own," here. 

About Johnson and the book-making process here. (I got the above altered page image from Johnson's copy of Paradise Lost here.) Some reviews here, here, here, and (if you have access to J-STOR) here.
