Bilimek, born in 1813 in Nový Jičín in Moravia, entered the Cistercian monastery of Neukloster in Wiener Neustadt and was ordained a priest in 1837. His pastoral duties left him ample opportunity for natural history: he climbed the mountains of Lower Austria more than a hundred times, collected plants and insects on the Adriatic coast, and surveyed the fauna and flora of Lake Balaton and the Bakony Mountains in Hungary. As a professor of natural history and theology at military educational institutions across the empire, he curated teaching collections and cultivated ties with Vienna’s learned societies and prominent geologists. These credentials, though never formalized by an academic degree, positioned him at the heart of an expanding imperial project to catalog the natural wealth of the Habsburg lands.

That project had a distinctly underground dimension. Beginning with the first description of a cave-dwelling insect, the beetle Leptodirus hochenwartii, in Postojna Cave in 1832, the karst region between Ljubljana and Trieste became a magnet for naturalists. The cave cricket Troglophilus cavicola and the blind ground beetle Anophthalmus schmidtii soon followed, and a lively commercial trade developed around these rarities. Caves came to symbolize regional identity within the monarchy, and imperial visits to sites such as the Moravian Karst and the Aggtelek Karst prompted improvements in paths and lighting that sometimes revealed unknown passages. In 1824, Postojna Cave received an official imperial-royal Cave Management with regular guided tours, turning it into what the study calls the archetype of an

The commercial dimension of this early cave science deserves particular attention, because it shaped both what was collected and how the resulting knowledge circulated. The trade in the olm, or Proteus anguinus, the pale aquatic salamander endemic to the Dinaric karst, had already established a template in the first half of the nineteenth century: live specimens were shipped to courts, cabinets, and menageries across Europe, and the animal became a diplomatic gift as much as a scientific object. Cave insects followed a similar trajectory, though on a smaller scale. Local guides and cave keepers knew where the eyeless beetles could be found under stones and in damp detritus, and their cooperation was essential for collectors like Bilimek, whose success in Koblarska jama depended on systematic searching of precisely those microhabitats. The capture of fourteen specimens of Anophthalmus schmidti at only the third known locality for the species illustrates how fieldwork, local knowledge, and the economics of rarity combined to produce new distribution records that fed directly into the descriptive literature of the period.

It is worth emphasizing how unusual this attention to cave animals was at the time. Before the 1830s, subterranean environments were generally regarded as biological voids, places where the absence of light was assumed to preclude life. The description of Leptodirus hochenwartii, a beetle so strange that it was initially placed in its own family, forced naturalists to confront the possibility that caves harbored organisms found nowhere else. Over the following two decades, each new discovery—the cave crickets, the blind beetles, the white crustaceans of karst springs—raised the same set of questions: were these animals relics of an ancient fauna that had taken refuge underground, or were they recently adapted descendants of surface ancestors? How did they navigate, feed, and reproduce in perpetual darkness? These questions could not be answered from specimens alone, and the era’s collectors, working before the consolidation of experimental methods, contributed primarily by accumulating the comparative material on which later synthesis would depend.

Bilimek’s comparative instinct, evident in his desire to match his Mexican cave observations against his Carniolan experience, anticipated the explicitly biogeographical framing that would later define biospeleology. When Emil Racoviță published his manifesto in 1907, he drew on decades of accumulated distribution data to argue that cave faunas were not random assemblages but structured communities shaped by isolation, climate history, and the peculiar selective regime of the underground. The specimens gathered by amateurs and semi-professionals in the mid-nineteenth century, often with little theoretical agenda beyond the thrill of rarity, became the empirical substrate for that argument. Bilimek’s Grutas de Cacahuamilpa, with its tropical cave fauna so different from the temperate European karst, offered exactly the kind of disjunct distributional evidence that made such comparisons intellectually productive.

The Grutas de Cacahuamilpa themselves merit description, since they were among the most celebrated caverns in nineteenth-century Mexico. Located in the mountains of Guerrero state, not far from Taxco de Alarcón, the caverns had long been known to local communities before European naturalists described them. Their enormous chambers, some among the largest known in the world at the time, attracted visitors during the French intervention period, and their fauna—unlike the specialized troglobites of the Slovenian karst—included many species that were only partially adapted to subterranean life. This distinction, between troglobites confined to caves and troglophiles that move between surface and underground, would only be formalized much later, but collectors like Bilimek were already implicitly grappling with it as they sorted their captures into those that seemed cave-bound and those that appeared to be strays from the surface world.

The institutional context in Mexico City also shaped what Bilimek could accomplish. The Imperial Mexican Museum at Chapultepec Castle, which he directed as curator, was conceived as a counterpart to the Vienna Imperial Collections, and Maximilian’s broader cultural program—including the founding of the Mexican Academy of Sciences and Literature—deliberately transplanted Austrian institutional models to Mexican soil. For a naturalist like Bilimek, this meant that collecting in Mexico was not simply a private passion but a state-sanctioned activity embedded in an apparatus of display, cataloging, and imperial representation. The museum’s collections were intended to showcase the natural and antiquarian wealth of the new empire, and caves, as repositories of both unusual fauna and pre-Columbian artifacts, occupied a double position within that program: they were scientific sites and heritage sites simultaneously.

This duality helps explain the critical reassessment that Bilimek’s Mexican activities have undergone in recent scholarship. The removal of pre-Columbian artifacts from culturally significant caves, such as those near Orizaba in Veracruz, and their transport to Europe as part of the imperial collections, is now understood as part of a broader pattern of extraction during the intervention period. Postcolonial and museological studies have documented how such collections were assembled under conditions of unequal power, and how their subsequent display at Miramare Castle and transfer to Viennese museums fixed them in European institutions far from their contexts of origin. For historians of science, this raises the question of how to weigh the scientific value of the specimens and observations Bilimek made against the political circumstances under which they were acquired—a question that applies to much nineteenth-century natural history but is particularly acute for material taken from sites of cultural and religious significance.

The fate of the collections after 1867 also illustrates the fragility of scientific enterprises built on imperial patronage. When Maximilian was captured and executed by the restored republican forces, the museum project at Chapultepec collapsed, and Bilimek’s priority shifted from acquisition to salvage. That he managed to arrange the transport of the extensive collections to Europe at all was a considerable logistical achievement, involving shipping, negotiation, and the protection of fragile specimens during a period of political upheaval. His subsequent career as curator at Miramare Castle, where the Mexican collections were exhibited near Trieste, kept him connected to the material for another decade, and his later collecting journeys to North Africa and Palestine show how the habits of a scientific collector persisted even after the imperial framework that had enabled them had dissolved.

For the history of subterranean zoology specifically, the study’s emphasis on networks rather than lone genius carries an important methodological implication. The discovery of cave fauna in Carniola is often narrated through the names of a few naturalists—the count who financed the exploration of Postojna Cave, the entomologists who described its beetles—but behind them stood a much larger cast: cave keepers who noticed unusual animals, local priests who corresponded with Vienna, merchants who shipped specimens, and teachers like Bilimek who trained cadets in natural history and passed on the collecting ethos. The military educational institutions where Bilimek taught were themselves significant nodes in this network, since they dispersed scientifically literate officers across the empire’s territories, some of whom would encounter caves and karst in their postings and report their observations back to the learned societies of the capital.

The period following the revolutions of 1848 and 1849 added a further layer of urgency to these scientific activities. The Habsburg monarchy, shaken by internal rebellion and external pressure, invested in geoscientific, biological, and archaeological surveys that were meant to demonstrate the coherence of its territories as a natural and cultural unit. Mapping the empire’s caves, cataloging their unique species, and connecting them to a shared imperial narrative of exploration served political ends as much as scientific ones. That Bilimek, a monk from Moravia teaching in military academies, could move from the karst of Lower Austria and Hungary to the caverns of central Mexico within a single career shows how thoroughly the infrastructure of empire—its schools, museums, railways, shipping lines, and patronage networks—had become the medium through which knowledge of the underground world was produced.

In this light, the emergence of subterranean zoology as a distinct field appears less as an inevitable progression of disciplinary specialization and more as the contingent outcome of particular historical circumstances: a karst landscape crossed by imperial routes of trade and tourism, a court interested in natural history as an instrument of legitimacy, and a generation of collectors whose curiosity was matched by their mobility. The systematization that Racoviță and René Jeannel would achieve in the early twentieth century gave the field its name and its theoretical foundations, but the raw material on which that synthesis rested had been gathered, specimen by specimen, by figures like Bilimek working in the shadow of empires.
