Abrafaia

Abulafia is Jacopo Belbo’s computer, a machine whose files preserve his writing and whose password becomes a miniature test of the novel’s competing ideas about knowledge. Its secret is not a hidden word that grants mastery: Belbo’s answer to the question of whether he has the password is “No,” a refusal that Casaubon ultimately reads alongside Belbo’s refusal to submit to the people who claim to have discovered the Plan.

The Computer and Its Files

Abulafia enters the story as the electronic setting for Belbo’s private writing. In Casaubon’s account, Belbo turns to it again after giving up the idea of writing, but does not have the heart to recover earlier lines and subject them to electronic humiliation. The machine thus stands at the junction of preservation and exposure: it can hold a record, yet bringing that record back into view also changes the relation between the writer and what he once wrote.

Belbo’s papers elsewhere in his life remain materially scattered. Casaubon later searches through the cupboard of juvenilia, finding school exercises and bundles of adolescent poems and prose, including a text whose layered handwriting may represent revisions made across many years. Abulafia is not simply a replacement for that cupboard; its electronic files belong to Belbo’s later attempt to write again, while the handwritten pages preserve the earlier memories he never fully discarded.

The Password and the Refusal of Mastery

At the end of the novel, Casaubon remembers Belbo’s first “no” as an answer to Abulafia and to anyone who would try to steal its secret. The question is whether Belbo has the password; the answer is “No.” For Casaubon, the response does not reveal a second, concealed password. The magic word does not exist, and, more radically, its absence is not something the questioners can claim to know with certainty. Admitting ignorance leaves room to learn; pretending that every secret has a key closes that room.

The answer reverses the usual promise of a password. A password ordinarily marks the boundary between outsiders and initiates, offering entry to those who possess the right token. Here, Belbo’s denial refuses the premise that access to knowledge depends on possession of a secret word. The computer’s hidden interior invites the same appetite for an ultimate explanation that animates the Plan, but the answer blocks that appetite without replacing it with another key.

Abulafia and the Plan

The novel’s earlier account of the Provins message shows how easily cryptographic procedure can be made to serve a prior theory. Colonel Ardenti presents a photocopy rather than risk further wear to the original, then argues that Ingolf’s transcription must be true because he sees no way the truth could be otherwise. He treats the copy as the original by force of conviction, not by independent verification. His method makes belief do the work that evidence should do.

Ardenti describes trying the first of Johannes Trithemius’s forty major systems, then taking the initial letters of each word. That sequence remains nonsense until he applies a second, minor system: a simple shift in which each coded letter is replaced by the following letter. The result is a French phrase announcing thirty-six invisibles divided into six groups. The steps produce a legible reading, but legibility alone cannot establish the message’s provenance or the historical story Ardenti builds around it.

Casaubon later offers a reverse explanation. The French phrase, he observes, uses wording associated with a seventeenth-century pamphlet from the Rosicrucian appearance in Paris; the Trithemius-style encoding therefore need not prove that Templars anticipated later Rosicrucian language. Ingolf could have found the message, recognized its suggestive numbers, and encoded a sentence of his own as a cryptographic exercise. The alternative does not prove that this is what happened, but it exposes the gap between decoding a text and proving the history attached to it. Abulafia’s password scene condenses the same caution: a demand for hidden certainty can turn a possible interpretation into an allegedly inviolable secret.

Belbo’s Two Noes

Casaubon distinguishes Belbo’s answer to the computer’s password question from his second “no,” spoken when the Plan’s followers offered him a way to save himself. Belbo could have invented or borrowed a map, but he refused to bow. Casaubon reasons that the group’s incorrectly hung Pendulum would not have led them to the true location, even if they had found the marked point; nevertheless, Belbo chose death rather than provide the submission they demanded.

The parallel gives Abulafia’s refusal its final weight. Belbo’s first “no” denies that knowledge can be reduced to a password; the second refuses to exchange truthfulness for survival under a delusion of certainty. Casaubon understands the two refusals as resistance not merely to power, but to nonmeaning: even in a fragile world, something matters more than the all-explaining Plan. Abulafia remains a computer, but its unanswered password becomes the emblem of a limit that the Plan’s logic cannot tolerate.
