Collecting empires: Dominik Bilimek and early subterranean zoology between politics and field research

The Moravian Cistercian monk and collector Dominik Bilimek (1813–1884) is considered one of the earliest European naturalists to conduct zoological research on subterranean fauna in Latin America. During the second French invasion of Mexico, from 1861 to 1867, he accompanied Maximilian of Habsburg, the newly enthroned emperor of Mexico, to the region. There, he explored the Grutas de Cacahuamilpa near Taxco de Alarcón, comparing its fauna to his earlier discoveries in Postojnska jama in Carniola (Slovenia). After the victory of the Mexican republican forces and Maximilian’s execution, Bilimek retained his role as curator of the emperor’s collections, which he took back with him to Europe and exhibited at Miramare Castle near Trieste. Prior to his Mexican venture, Bilimek had embraced the imperial goals and intellectual agendas of the Viennese central administration while teaching at the monarchy’s military institutes. Following the revolutions of 1848/49, extensive research undertakings—including geoscientific, biological, and archaeological surveys—were initiated to preserve the Habsburg monarchy as a supranational entity amidst internal and external crises, and to legitimize its territorial framework as both a natural and cultural unit. These developments coincided with the initial surge of zoological interest in Carniolan caves, which spurred efforts to gather similar findings in other karst regions of the monarchy. Drawing on historical sources, this article explores the intersection of political concepts and fieldwork practices in the early study of cave biology. Special attention is given to the sites, networks, and modes of collecting during this transformative period.
