Prehistoric man — Reading Notes

The Copper Mines of Lake Superior

Wilson devotes considerable attention to the ancient copper mines of the Keweenaw Peninsula, where modern miners in the 1840s and 1870s uncovered extensive prehistoric workings. At the Minnesota Mine site, trenches eighteen to thirty feet deep were found, partially filled and overgrown, containing massive masses of native copper. One detached mass weighed upwards of six tons, resting on an artificial cradle of black oak preserved by water. Alongside it lay copper tools and stone mauls, abandoned as if work ceased suddenly.

The detail is precise: the mass measured ten feet long, three feet wide, and nearly two feet thick, with every projecting piece removed to leave a smooth surface. Wilson notes that the absence of copper tools in some trenches suggests 'the final desertion of the mine, from some unknown cause, at the very time when its resources were most available.' He contrasts the primitive metallurgist's limitations—no harder material than native rock and ductile copper—with the modern miner's ability to reach deeper veins.

These observations are not mere description; they serve Wilson's broader argument that prehistoric peoples achieved sophisticated engineering without metal tools, and that their abandonment of such rich sites remains unexplained.

Analogous Civilizations, Independent Origins

Wilson's central thesis is that the civilizations of the Old and New Worlds developed independently, yet followed parallel paths. He argues that the recognition of this analogy is 'of value as an aid to the realisation of the necessary conditions through which man passed in reaching the stage at which he is found at the dawn of history.' This is not a claim of diffusion or contact, but of inherent human capacities unfolding under similar pressures.

The evidence for this comes from archaeological remains—tools, monuments, mining operations—rather than written records. Wilson coined the term 'prehistoric' precisely to denote 'the whole period disclosed to us by means of archaeological evidence, as distinguished from what is known through written records.' He notes that the term was quickly adopted by European archaeologists, but that its meaning has been narrowed by later subdivisions.

In the New World, he finds 'many respects strikingly analogous' to the Old, from the use of copper to the construction of earthworks. Yet he is careful not to overstate: the excerpts show him grounding his claims in specific artifacts and sites, not in sweeping generalizations.

The Abrupt Abandonment of Ancient Works

A recurring pattern in Wilson's account is the sudden desertion of sophisticated mining operations. At the Cliff Mine, a heart-shaped mass of nearly pure copper weighing between two and three tons was recovered in 1874 from an ancient trench, alongside smaller pieces broken off by the original workers. Stone mauls and hammers lay scattered, but no copper tools—suggesting the miners left abruptly, perhaps due to some unknown catastrophe or social disruption.

Wilson reports that the ancient trenches were 'partially filled up, and so overgrown in the long interval between their first excavation and their observation by recent explorers, that they scarcely attract attention.' Yet modern miners eagerly follow these traces as clues to rich deposits. The contrast between the ancient and modern approaches is stark: the former worked with stone and copper, the latter with advanced machinery; the former left behind enigmatic abandonments, the latter systematically erase the evidence.

These details—the six-ton mass on its oak cradle, the smooth surface of the detached block, the scattered tools—give the reader a vivid sense of interrupted labor. Wilson does not speculate on the cause, but the pattern itself becomes a kind of evidence for the fragility of prehistoric societies.

Wilson's Prehistoric Man rewards readers who attend to its concrete descriptions of artifacts and sites. The copper mines of Lake Superior, with their abandoned masses and scattered tools, offer a tangible entry point into his argument for independent, parallel development. Rather than seeking a single narrative, the book presents a series of detailed case studies that together build a case for the inherent creativity of prehistoric peoples. Readers may find it useful to compare the New World evidence with Wilson's earlier work on Scotland, noting how his comparative method operates across continents.

Reading about those abruptly abandoned copper mines, I thought of the crannogs—homes built on water, left mid-life. There’s a melancholy in unfinished work we don’t understand.
