The catalog of the mineralogical collection of the Emperor Leopold II (1747–1792): collecting and learning in eighteenth-century Europe

The Collectio Mineralium (1765) currently preserved at the Historical Archive of the Natural History Museum of the University of Firenze, is the unpublished catalog of the mineralogical collection that belonged to Emperor Leopold II (1747–1792). The catalog is a 110-page register, with the golden emblem of the House of Habsburg at the center of the binding, containing information about 242 mineralogical samples. Each specimen is carefully described (i.e., habit, metal content, product value) and its locality given. The interpretation of the text has also returned information on most of the mining deposits in the Austro-Hungarian territories in the eighteenth century. Therefore, the interpretation of this catalog—that on the basis of the literature appears to be the first catalog of a collection belonged to a Habsburg emperor—represents an important step toward enhancing our understanding of Habsburg natural history collections and reflected the transition from wonder-rooms to commodity collecting. Leopold’s private collection was no longer an ‘instrument of wonder’ but it became representative of scientific collecting characterized by the establishment of systematic mineralogy, and by a careful economic evaluation of the mineralogical samples collected as a symbol of the power of the Austro-Hungarian Empire.
