To create his 1970 novel A Humument, British artist Tom Phillips began with W.H. Mallock’s forgotten 1892 novel A Human Document and drew, painted, and collaged over the pages, leaving a few words showing to tell a new, hitherto unrevealed story. For instance, the title arises from Phillips’ deletion of two central syllables in Mallock’s title, and the protagonist, Bill Toge, can appear only when the word “together” or “altogether” arises in Mallock’s original text.

Even this new text is evolving. Phillips has published five editions of the book, in each of which he replaces certain pages; eventually he hopes to replace every page, creating an entirely new work (or an entirely new version of the same work).

“Can we call what Phillips is doing ‘writing’, or would some other term be better?” asked Adam Smyth in the London Review of Books. “What version of authorship or creativity is at work here? A Humument is a reminder that books are inevitably intertextual — they grow out of older texts — and that all writing involves selecting words from a finite pool: what appears to be a constraint, having to work within the walls of an existing novel, in fact dramatises a condition of literature.”

The full text of the 1970 edition is here.

Doctor [John] Gillies, the historian of Greece, and Mr. [Richard] Porson used now and then to meet. The consequence was certain to be a literary contest. Porson was much the deeper scholar of the two. Dr. Gillies was one day speaking to him of the Greek tragedies, and of Pindar’s odes. ‘We know nothing,’ said Dr. Gillies, emphatically, ‘of the Greek metres.’ Porson answered, ‘If, Doctor, you will put your observation in the singular number, I believe it will be very accurate.’

Edgar Allan Poe’s “The Murders in the Rue Morgue” is credited with being the first modern detective story — biographer Jeffrey Meyers says it “changed the history of world literature.” The story established the convention of the brilliant investigator who unveils a climactic revelation before explaining the reasoning that led him to it. The lead character, C. Auguste Dupin, served as a prototype for fictional detectives from Sherlock Holmes to Hercule Poirot.

But Poe himself thought the praise was overblown. “These tales of ratiocination owe most of their popularity to being something in a new key,” he wrote. “People think them more ingenious than they are — on account of their method and air of method. In the ‘Murders in the Rue Morgue,’ for instance, where is the ingenuity in unraveling a web which you yourself … have woven for the express purpose of unraveling?” The brilliance of a detective story is transparently contrived, he said: “The reader is made to confound the ingenuity of the suppositious Dupin with that of the writer of the story.”

I remember, many years ago, when my imagination was warm, and I happened to be in melancholy mood, it distressed me to think of going into a state of being in which Shakespeare’s poetry did not exist. A lady whom I then much admired, a very amiable woman, humored my fancy, and relieved me by saying, ‘The first thing you will meet in the other world will be an elegant copy of Shakespeare’s works presented to you.’ Dr. Johnson smiled benignantly at this, and did not appear to disapprove of the notion.

Thomas Carlyle required absolute silence to write, and silence was hard to come by in London’s Chelsea district, where he struggled to compose his biography of Frederick the Great. His wife, Jane, postponed her cleaning until Thomas was away and perpetually tried to quiet neighborhood dogs, roosters, and street vendors. But it wasn’t enough.

In 1853 Carlyle wrote to his sister: “At length, after deep deliberation, I have fairly decided to have a top story put upon the house, one big apartment, twenty feet square, with thin double walls, light from the top, etc., and artfully ventilated, into which no sound can come; and all the cocks in nature may crow round it without my hearing a whisper of them!”

Alas, the skylight wasn’t soundproof, and he was assailed by railway whistles, church bells, and steamer sirens from the Thames. Jane wrote, “The silent room is the noisiest room in the house, and Mr. Carlyle is very much out of sorts.” He finished the biography, finally, but he called it “the Nightmare … the Minotaur … the Unutterable book.”
