As above, so below
Foucault's Pendulum“As above, so below” is the maxim that makes correspondence feel like a method of discovery: a pattern observed at one level of reality can be projected onto another. In the novel, that promise powers an occult account of ancient knowledge, the Plan’s construction, and the more dangerous conviction that connections prove themselves.## Cosmic Correspondence In the account of supposed Celtic knowledge, the maxim links the heavens to the earth. Megaliths are described as instruments in a global system: menhirs mark branching currents, leys trace their routes, dolmens accumulate energy, and cromlechs and Stonehenge serve as observatories. Their builders supposedly read the constellations to infer the pattern of terrestrial currents. The maxim thus supplies the premise that makes these diverse structures parts of one intelligible design.
This imagined system grows through successive transmissions. The speaker traces occult knowledge from the survivors of Atlantis to the Celts, and through Hermes Trismegistus and Moses to the Kabbalists, who supposedly grasped the higher truth encoded in the Pentateuch. The sweeping genealogy illustrates the maxim’s appeal: differences of place, age, and tradition become evidence of a single correspondence. The more traditions it encompasses, the more comprehensive—and less verifiable—the system appears.## From Correspondence to the Plan The same impulse organizes the characters’ treatment of the supposed Templar message. Casaubon first dismisses the familiar legend that Templars escaped France in an ox-drawn hay wain and carried their secrets to Scotland, where they entered a Masonic lodge. He recognizes that pamphlets repeat the tale without foundation. Later, however, he reads the message anew and treats Tomar as the Templars’ real first meeting place. The shift is consequential: he recalls that the task is not to discover the Templars’ secret but to construct it.
The characters’ own rules for constructing the Plan make the underlying logic explicit. Concepts connect by analogy; if the chain eventually returns to its starting point, it is accepted as coherent; and its links must already have been made by others. A chain can run from a potato through an apple, a snake, a doughnut, and a life preserver, eventually back to the potato. The maxim’s expansive promise has become a procedure in which resemblance supplies connections and circularity certifies them. What once appeared to reveal a design now helps manufacture one.## Interpretation and Counterargument Diotallevi’s interpretation of Christian history demonstrates the same method at its most extravagant. Repeated references and suggestive gaps become keys: he claims Jesus was not crucified, identifies him with the King of the World, makes Mary Magdalene his bride, and casts him as founder of the Rosicrucians and the French royal line. In this account, correspondence does not merely connect separate traditions; it fills what the texts do not say with an elaborate hidden narrative.
Lia’s criticism offers the novel’s clearest counterweight. She calls the Plan grotesque rather than poetic, distinguishing its murky promises and contradictions from the clarity of Homer. People, she argues, find in the manifestoes what they want to find; the characters have joined truths that do not belong together, and their incoherence can pass for mystery. Her eventual explanation is decisive: the Provins message is a laundry list, not evidence of Templar meetings or a historical Plan. The analogy-driven crossings made it seem meaningful, but the meaning belonged to the interpreters.
The maxim therefore holds two roles in the novel. It names the seductive hope that the world’s different levels mirror one another, and it exposes the interpretive habit by which that hope can turn resemblance into certainty. Correspondence can organize a genuine pattern, but without a way to distinguish strong links from arbitrary ones, the search for hidden order becomes a means of inventing it.
