Geological & Mining

The systematic study of geology emerged as a discipline in the late eighteenth century, and the antique prints and maps associated with its development record one of the great intellectual revolutions in the history of science. William Smith’s 1815 geological map of England — the first true geological map of a country — transformed the way human beings understood the deep structure of the earth beneath their feet, and opened the door to an entirely new way of reading landscape. The prints and maps in this collection trace that transformation from its origins to its maturity in the great geological surveys of the nineteenth century.

Geological illustration presented illustrators with challenges unlike those of any other natural history subject. The objects of study were often invisible — hidden beneath overburden, exposed only in cliff sections, quarry faces or mine workings — and their three-dimensional structure could be suggested but not shown directly on the flat surface of a print. The cross-section became the central convention of geological illustration: a diagrammatic slice through the earth showing the relationship of strata, faults and intrusions in a way that integrated field observation with theoretical interpretation. The finest examples of this genre are intellectually demanding and visually elegant in equal measure.

Fossil illustration developed alongside geological mapping as the two disciplines reinforced one another. The recognition that different strata contained different characteristic fossils — Smith’s key insight — gave fossil specimens a new scientific importance as markers of geological time, and illustrators were called upon to document them with the same precision applied to living natural history. The great fossil monographs of the nineteenth century — covering ammonites, belemnites, trilobites, plant fossils and the increasingly spectacular vertebrate remains being recovered from British, European and American formations — produced some of the finest scientific illustration of the era.

Mining views occupy a different register: documentary rather than analytical, they record the physical reality of extractive industry at a moment of rapid technological change. The coal mines of northern England, the tin and copper mines of Cornwall, the gold diggings of California and Victoria, the silver mines of Mexico and Peru — all attracted artists who recognised that the industrial landscape was as worthy of record as the natural landscape it replaced or disrupted. Australian mining scenes are of particular interest, recording the goldfields that transformed the colonies from the 1850s onwards and the later mining booms in silver, copper and other minerals.

Geological maps form a distinct and specialised collecting area. The great national and colonial surveys of the nineteenth century — the Geological Survey of Great Britain, the surveys of the various Australian colonies, the United States Geological Survey — produced maps of exceptional technical quality that also function as handsome objects. Coloured by hand or by later chromolithographic processes to indicate different geological formations, they are visually striking in a way that topographic maps rarely achieve, and their scientific importance as records of knowledge at a particular moment is considerable.

For collectors with interests spanning the history of science, industrial history or the social history of mining communities, this is material of unusual breadth. It connects the abstract world of geological theory with the concrete realities of extractive industry, and documents both in forms of considerable visual and intellectual interest.
