Telluric currents

Telluric currents begin as an occult explanation for the forces supposedly running beneath the earth. In the Plan devised by Casaubon, Jacopo Belbo, and Diotallevi, they become the hidden infrastructure of history: a planetary network whose currents can be traced to a commanding center and controlled. The notion gives their invented Templar secret an elegant mechanism, but its growth also demonstrates the danger at the heart of the novel: when every resemblance is made to confirm every other, an acknowledged fiction can acquire the force of reality.

From subterranean currents to a planetary system

Salon presents underground currents as the reason plots must operate beneath the surface. In his account, dominion over the world means dominion over what lies under it. He connects this claim to Celtic sanctuaries and tunnels, sacred wells, menhirs, pyramids, and the supposed alignments of sacred places. The earth’s depths become not empty geology but a concealed system of power, legible to those who know how to interpret its signs.

His explanation draws on occult and mythic correspondences. Stones set into the ground are recast as probes or antennas inserted at the planet’s nodal points; below them, he imagines a central fusion nucleus, a sun-like core around which the telluric currents follow their courses. The idea links the subterranean to the cosmic and makes ancient monuments look like instruments in a planetary apparatus. Salon also invokes the alchemical maxim VITRIOL, turning descent into the earth’s interior into a route toward hidden knowledge. For Casaubon, however, the tunnel is an origin to leave behind, not a destination. The contrast matters: he is drawn into Salon’s system of associations even as he recognizes the need to emerge from it.

The secret the trio supplies

After Lia gives birth, Casaubon stays home with her and the baby. He reads the materials he has collected on telluric currents during this period, then brings his notes to Belbo and Diotallevi. They decide that the currents can supply the Templars with the secret their fabricated history requires: a compact explanation that makes its scattered pieces appear to fit.

The trio’s account constructs a lineage of hidden knowledge. The Celts supposedly learned about the currents from survivors of Atlantis, who had received the secret from ancestors crossing a primordial landmass. The story then extends to a concealed pole and an unreadable alphabet, placing the currents inside a chain of lost civilizations and inaccessible wisdom. These are not independent discoveries that corroborate one another; they are components the trio assembles into an increasingly comprehensive fiction.

Their theory gives the current system a precise objective. The earth is treated as a great magnet, affected by celestial forces, seasonal cycles, and the precession of the equinoxes. Because its pattern changes, the Templars would need not only a global map of the currents but also the critical point from which they could be directed: the Navel of the World, the source of command. The stages of alchemical work are then reinterpreted as metaphors for investigating and mastering this planetary rhythm. The supposed secret of alchemy and the Templars becomes the search for its wellspring.

The trio makes the stakes explicit by imagining what control would permit. A powerful valve at the Telluric Navel could, in their account, foretell weather and produce disasters on a vast scale. It would provide leverage over governments far beyond the destructive reach of a weapon that also harms its user. The fantasy turns a mystery about hidden currents into a political instrument: whoever finds the command point would hold the world’s rulers to ransom. The grandness of this imagined power is part of the theory’s appeal, not evidence that such a mechanism exists.

Expanding the Plan

The currents return when the trio expands its theory to absorb Nazi occultism and hollow-earth speculation. Casaubon proposes, as part of their increasingly extravagant construction, that Hitler might have acted like a living valve transmitting subterranean forces to crowds. The claim converts political influence into a fictional consequence of access to the currents, making a historical phenomenon another apparent confirmation of the Plan.

The hollow-earth theory lets the invented system join the upper and lower worlds. In the trio’s account, Hitler’s conquests become steps toward acquiring parts of the Plan and reaching its interpretive instruments. The theory even folds the Holocaust into its imagined search for a hidden clue to the point where the currents converge. This is a fictional and deeply disturbing distortion, not an explanation of the Holocaust: the conspiratorial frame appropriates an atrocity as evidence for its own imagined machinery. The same construction identifies the earth’s hidden center with the Mystic Pole and makes subterranean passages mirror the pattern of the stars. What began as underground currents has become a total scheme in which the sky, the earth, history, and political violence are made to signify one another.

Instruments, evidence, and manufactured belief

Later, as Casaubon reads machines in the museum through the Plan, ordinary mechanisms appear to be devices for registering or relaying telluric currents. Accumulators become instruments for collecting signals from distant places, while a sewing machine’s coil seems to announce its purpose on a label referring to currents induced from the terrestrial field. These readings show how the Plan absorbs objects that have explanations outside it: the objects are not proof of the conspiracy, but Casaubon’s interpretive habit makes them look like its traces.

The invention works because the trio has trained itself to connect everything. At first, they recognize that their associations are unwarranted and treat them as parody. Over time, however, collecting material for the game makes connection automatic, and Casaubon sees the danger in the resemblance between pretending to believe and learning to believe. The three men are affected differently, but the currents belong to the shared system that blurs metaphor and fact. Their conjecture that a secret society might spread the rumor of a universal plot captures the same self-reinforcing logic: the absence of a real plot can itself be explained as evidence of a concealed one.

The Plan’s invention eventually persuades its audience because people identify fragments of their own confused mythologies in the trio’s pattern of analogy and suspicion. Once those believers act on the nonexistent Plan and search for its map, the fiction acquires consequences in the world. Telluric currents therefore have a double role: within the Plan, they are the hidden force that promises command over the planet; in the novel’s account of belief, they are a demonstration of how a compelling explanatory system can manufacture the confirmations it claims merely to discover.
