Abstract

This paper examines cave environments as unique spaces of knowledge production and shows how visualizations of natural cavities in maps came to be powerful tools in scientific reasoning. Faced with the challenge of limited vision, mapmakers combined empiricism and imagination in an experimental setting and developed specific translation strategies to deal with the uncertain origin of underground objects and the shifting boundaries between the known and the unknown. By deconstructing this type of cartographic representation, which has barely been studied, this paper furnishes surprising insights into the scholarly practices and tools used to deal with this considerable epistemic uncertainty and to signal credibility and trust to potential users. The array of maps used for this study includes both archival and published sources, depicting caves in Europe, America and Siberia.

28 Although Athanasius Kircher's two-volume Mundus subterraneus contains numerous visualizations of subterranean space, none of these images depicts a specific cave. In the first edition, Kircher discusses caves in Chapter 20 (‘About caves, cracks, and innumerable passages of earth’) at the end of ‘Liber secundus’, but quotes mainly ancient authors. In the third edition, a letter by Cornelius Magni from Parma is reproduced at the end of the chapter with an account of his visit of Antiparos Cave in 1673. Kircher himself only refers to having visited the Monte Serana Cave near Trevi (Umbria). See Stephan Kempe, Gottfried Naumann and Boris Dunsch, ‘Athanasius Kircher's chapter XX “About caves, fractures and the innumerable passages of the earth” and the Grotto of Antiparos from “Mundus subterraneus”, 1678, translated from Latin’, in Michal Filippi and Pavel Bosák (eds.), Proceedings 16th International Congress of Speleology, Brno, 2013, vol. 1, Prague: Czech Speleological Society, 2013, pp. 59–64.

34 The underground's perceived exclusionary character was supported by the fact that early cave maps often omitted above-ground topographies. Likewise, overground maps frequently did not show cave entrances, thus denying the existence of a subterranean topography. The first topographical map to use uniform cartographic symbols for the designation of cave entrances was probably a hydrological map of Slovenia published in Belsazar Hacquet's Oryctographia Carniolica (1778–89). See Belsazar Hacquet, Oryctographia Carniolica, vol. 1, Leipzig: Breitkopf, 1778. A section of the Sveta Jama cave (Slovenia) is depicted on the cover of the first volume.

43 The symbolic representation of Jesus’ birthplace – and also of Mary's womb – as a cave originated in the Eastern Catholic Church and is exemplified by the grotto of the Church of the Nativity in Bethlehem. This representation spread through Europe during the Middle Ages, entrenching the sense of underground cavities as feminine, fertile sites.

52 Early cave explorers were accustomed to see their own bodies as measuring tools, striding out the length of a cave's galleries. The hours or footsteps incurred during a given tour underground counted as evidence of the length of the cave. Like Theseus in the mythological labyrinth of the Minotaur, Dumas and his companions used a cord to orient themselves inside the cave.

60 For example, the Prussian military doctor Johannes Hain, who in 1672 had published a richly illustrated treatise on supposed ‘dragon bones’ found in Carpathian caves, commissioned the priest of a Piarist high school and a nobleman from Liptov (Slovakia) to map the local ice caves.

62 Other motifs, some of which relate to the labyrinth mythos, reflect an understanding of the subterranean world as counterpart of mountains or cities. These motifs came to have a degree of influence on early modern representations of mines and mining towns.

70 Epicartographic elements are map symbols that are not subject to graphic generalization or projection.

71 Providing a three-dimensional view of an object, cave maps of Geldloch and Taubenloch (Austria), drawn by the architect and painter Franz Rosenstingl (1702–85), met the visual expectations of the map users by enabling them to scan the entire cave by eye. See Joseph A. Nagel, ‘Beschreibung des auf allerhöchsten Befehl … untersuchten Oetscherberges’, 1747 (Austrian National Library, Ms. 7920), Tab. III, IV. Leibniz, for example, argued for a perspective map projection: ‘Hence, it would be necessary to draw a scenographic or perspective map of the mine, as if the eye were floating in the air and the mountain were transparent’.
