The Deutsches Museum is a vast, interactive museum in Munich where Casaubon conducts research on reproductions and encounters Signer Salon in a life-size underground mine. Its displays make human invention tangible, but its dark tunnels also turn the museum into an uncanny stage: amid the machinery and reconstructed workings, Casaubon meets a familiar face that seems to have surfaced from another world.

Research and Setting

At Signor Garamond’s authorization, Casaubon spends several days at the Deutsches Museum examining card catalogs of reproductions. His afternoons are devoted to the archives; his evenings take him to the bars of Schwabing or to crowded beer halls where elderly men in lederhosen play music. The museum offers a strikingly different atmosphere from those nocturnal gatherings and from the more Gothic Conservatoire: it is a place of demonstrative, forward-looking technology, filled with unruly school groups being taught to admire engineers.

The exhibits invite visitors to operate them. A button brings oil-drilling dioramas to life; visitors can enter a real submarine, set planets revolving, and experiment with acids and chain reactions. The museum presents invention not as an abstract sequence of ideas but as a set of mechanisms that can be watched, entered, and handled. For Casaubon, this makes it a useful research environment and a concrete counterpoint to the occult systems and historical correspondences increasingly occupying his thoughts.

The Mine and Salon’s Appearance

The mining exhibit extends that material realism downward. Visitors descend a ladder into a reconstruction complete with tunnels, elevators for people and horses, and narrow passages where wax figures of exploited children crawl. The route continues through dark corridors and past bottomless pits; firedamp is evoked as part of an immersive, life-size environment. The museum’s engineering display thus becomes a passage through a world of labor, danger, and darkness rather than a simple gallery of machines.

While wandering in one of these tunnels, Casaubon sees a pale, white-haired man with a wrinkled, owlish face looking over a railing. He recognizes the face before he can reconcile it with its civilian clothes: he had known the man as Signer Salon, the taxidermist whose laboratory was next door to Casaubon’s office in a former factory building. They had sometimes passed one another on the stairs and nodded without being introduced. In the mine, Salon takes the initiative, greets Casaubon in Italian, and remarks on the strangeness of their meeting far from the corridor where they had long been neighbors.

Narrative Significance

The encounter turns the museum’s subterranean setting into more than an elaborate exhibit. A familiar acquaintance appears unexpectedly in a reconstructed underground world, where the ordinary social geography of the office corridor has been displaced by tunnels and railings. The effect is not that Salon becomes a supernatural figure, but that the museum’s immersive architecture briefly makes recognition itself feel uncanny.

The Deutsches Museum also sharpens the novel’s contrast between demonstrable mechanisms and speculative interpretation. Its buttons, drills, submarine, and mine offer visible operations, while Casaubon’s wider inquiry moves among coded texts, historical claims, and conjectures about hidden connections. The museum can stage both impulses at once: it reconstructs human invention with exacting material detail, yet its dark corridors provide the setting for an encounter that unsettles the boundary between the familiar and the strange.
