Unveiling the Sources of Ancient Egyptian Copper

Scientists have applied chemical characterization techniques and lead isotope analyses to copper artifacts from ancient Egyptian burial sites (ca. 4400-2130 BCE) housed in museums in Germany and Belgium. The methods involve linking chemical and isotopic ‘fingerprints’ in the artifacts with those of copper ores in potential mining sites in the region. Inscriptions carved on rocks and archaeological sites around known sources of copper ore led archaeologists to theorize that ancient Egyptians obtained the copper they used to make items such as vessels, utensils, and weapons from the Sinai Peninsula and the Eastern Desert, or from as far away as Israel, Jordan, the Arabian Peninsula, and Anatolia.

Without scientific analyses, however, they had no way of pinpointing Egypt’s sources of copper and changes in their exploitation over time. While the discovery that early Egyptian copper came from local sources is not a surprise to the researchers, “it is a very important step in the scientific process to validate this analytically, as it allows us to deepen our understanding of how metallurgical technology evolved in Egypt,” says archaeological scientist Frederik Rademakers from Belgium’s Katholieke Universiteit Leuven.

Mining Practices and Trade Routes

The studies found that mining practices changed over time. Copper from items in the tomb of King Khasekhemwy, who ruled during the Early Dynastic Period and was buried in Abydos, about 170 kilometers north of Luxor, came from many sources in the Eastern Desert and the Sinai, for example. Copper artefacts from the later Old Kingdom tombs at Giza in northern Egypt were made only from Eastern Desert ores.

Lead isotope analyses of a copper vessel found in a First Dynasty (ca. 3000-2890 BCE) tomb from Abusir, just south of Giza, indicate that the vessel was similar to material in Anatolia. This is the earliest evidence of Anatolian-Egyptian copper trade that can be accurately dated. Ancient Egyptians may have desired the Anatolian metal because its combination of copper, arsenic and nickel gave it a unique [more whitish] colour, explains Egyptologist Martin Odler of Charles University in the Czech Republic. He expects the metal was part of the interregional trade in the late 4th and early 3rd millennia BCE.

Both studies examined copper artefacts housed in European museums due to difficulties in accessing archaeological samples in Egypt. Rademakers recognizes that his study’s findings might not reflect the full spectrum of copper objects in use in Ancient Egypt. This research is part of a bigger movement to understand the often-neglected subject of ancient metal working, says Nils Anfinset of Norway’s University of Bergen, who was not involved in the two studies. “The findings from these papers suggest that the Egyptians used a wide range of sources, painting a much more varied picture than was previously thought,” he says. The studies improve our understanding of how Egyptian civilization developed, he adds.

These findings highlight the importance of understanding ancient metalworking practices and the sources of metals used in ancient civilizations. The ability to identify the origins of copper artifacts provides valuable insights into trade routes, technological advancements, and the interactions between different cultures.

The Mystery of Michigan Copper

Recent scientific literature has come to the conclusion that the major source of the copper that swept through the European Bronze Age after 2500 BC is unknown. However, these studies claim that the 10 tons of copper oxhide ingots recovered from the late Bronze Age (1300 BC) Uluburun shipwreck off the coast of Turkey was “extraordinarily pure” (more than 99.5% pure), and that it was not the product of smelting from ore.

It is estimated that half a billion pounds (Ref.1) of copper were mined in tens of thousands of pits on Isle Royale and the Keweenaw Peninsula of Michigan by ancient miners over a period of a thousand years. Carbon dating of wood timbers in the pits has dated the mining to start about 2450 BC and end abruptly at 1200 BC. Officially, no one knows where the Michigan copper went. All the “ancient copper culture” tools that have been found could have been manufactured from just one of the large boulders.

A placard in London’s British Museum Bronze Age axe exhibit says: “from about 2500 BC, the use of copper, formerly limited to parts of Southern Europe, suddenly swept through the rest of the Continent”. Indian legends tell the mining was done by fair-haired “marine men”. Along with wooden tools, and stone hammers, a walrus-skin bag has been found (Ref.1). A huge copper boulder was found in the bottom of a deep pit raised up on solid oak timbers, still preserved in the anaerobic conditions for more than 3,000 years.

The mining appears to have ended overnight, as though they had left for the day, and never came back. During this thousand-year period of mining, some of the miners must have explored the continent to the west, as evidenced by strangely large skeletons in a lot of places, such as the red-haired giants who came by boat to Lovelock Cave on Lake Lahontan (Nevada), that were found in 1924 with fishnets and duck decoys (Ref.77). There is “biological tracer” evidence for foot traffic back and forth across the continent, more that three thousand years before the Lewis and Clark Expedition.

Pieces of the “native” Michigan copper sometimes have crystals of silver inclusions, mechanically enclosed but not alloyed; this is called “halfbreed copper”. The presence of silver nodules in “Old Copper Culture” tools shows they were made by hammering, called “cold working”. These hammered weapons and tools found in Hopewell mounds sometimes “show specks of silver, found only in copper of Lake Superior” (Ref. 69). Apparently, one instance of identification by silver inclusion has occurred overseas: In this letter of December 1st, 1995, Palden Jenkins, a historian from Glastonbury, writes, “I met the farmer who owns the land on which a megalithic stone circle is, called Merry Maidens, in far west Cornwall. While clearing hedges, he discovered an arrowhead, which was sent to the British Museum for identification.

Rapp and others (Ref.8,53) report that using trace element “fingerprints”, using mostly Lake Superior copper samples, probable geographic/geologic source identification can be done. The work of Hancock et al. (Ref.47) showed again that native copper, including Michigan copper, showed lower levels of tin, arsenic, gold, and especially cobalt, than “European copper” manufactured artifacts. The British Museum reported “generally low trace element content [in] our Egyptian artifacts” (Ref.2).

The cedar hull was badly damaged by a collision with the shore, but some of the wood was preserved by the corrosion products of the copper ingots. These ingots are all now in the Museum of Underwater Archaeology, in Bodrum, Turkey, with the ingots also found in the later date Cape Gelidonya shipwreck. These are more ingots than the total in all other museums and private collections put together.

Egyptian New Kingdom tomb paintings and temple reliefs depict a great number of copper ingots, but only one has been found in Egypt, as they were consumed there. For many years, the archaeological community has thought that lead isotope studies by an Oxford group, Gale et.al.(Ref.23,35,44,56) have proved that the ingots all came from Cyprus.

The Hauptman study concludes that “from a chemical point of view, the purity of the ingots is extraordinary in comparison with other sorts of copper from Wadi Arabah (high lead), from the Caucasus (high arsenic), from Oman (high arsenic and nickel). The ingots are made of pure copper, and all the ingots show a homogeneous composition. From our metallographic investigations, we are able to exclude a conscious purification or even a refining process to produce the ingots.

The 1989 (Ref.35) Gale report concludes that the Aghia Triadha ingots on Crete “are certainly not made of Cypriot copper”, and the copper source could not be identified. Dickinson, author of the Aegean Bronze Age (Ref.21) “From outside the Aegean came …oxhide ingots.

Between seven and ten thousand years ago, our early ancestors discovered that copper is malleable, holds a sharp edge, and could be fashioned into tools, ornaments, and weapons more easily than stone, a discovery that would change humanity forever. Gold is believed to have been used earlier than copper, though its softness and scarcity made it impractical for widespread use, whereas copper is harder and found in pure form (“native copper”) in many parts of the world.

The Sumerians and the Chaldeans living in ancient Mesopotamia are believed to be the first people to make wide use of copper, and their copper crafting knowledge was introduced to the ancient Egyptians. The Egyptians mined copper from Sinai and used it to make agricultural tools such as hoes and sickles, as well as cookware, dishes, and artisans’ tools such as saws, chisels, and knives. By comparing the purity of copper artifacts from both Mesopotamia and Egypt, scientists have determined that the Egyptians improved upon the smelting methods of their northern neighbors in Mesopotamia.

Ancient Mining in the Keweenaw Peninsula

Ancient mine pits, thousands of them, extending from the Porcupine Mountains north along the Keweenaw Peninsula and on Isle Royale proved it, he said. The extent of the work meant that tens of thousands of people must have been involved over the course of millennia, but they left no structures. No skeletal remains.

Throughout the remainder of the 1800’s and the 1900’s, dozens of professional and amateur archaeologists scoured the region, finding more and more evidence of the ancient miners of the Keweenaw.

The area nearby has one of the greatest concentrations of ancient mine pits, and Ruutila, an amateur archaeologist who has lived all but a few of his years as a resident of Ontonagon, has agreed to take me deeper into the world that holds my fascination. What enabled ancients to mine and use copper here is that the metal exists in a nearly pure, or native, state. Even North America’s earliest people figured out how to break off a chunk, pound the soft metal with a rock and come up with a spear point, no smelting required. The area has the largest concentration of native copper in the world.

The smallest stones are the size of softballs, the largest like loaves of bread. If you were to see one on the beach you wouldn’t look twice. But look more closely and you’d see a shallow band, about an inch wide, etched around the middle. These are the rocks, called hammerstones, that the ancients used to pound away at basalt to get at copper deposits. For some reason, seeing the hammerstones brings the ancients more into focus than did the finished copper artifacts. Perhaps because it’s easy to picture a man working, swinging the rock, his job, day in, day out.

Early American miners quickly learned to trust the ancients’ judgment. “They looked for the depressions and said, ‘okay, we’ll just dig here,’” Whiteman says. It’s copper metal-blue-green because of oxidation-oozing from the rock 99 percent pure, and it’s what made the Keweenaw famous, even among the ancients, apparently. Just pry it loose and pound it into a knife, a bead, a breast plate.

Lined with leaves and dirt and branches, the pits look like natural dips in the earth. “See how the edge is rounded, not angular,” Ruutila says. “That’s one way to tell if it’s a white man’s mine or an ancient mine.” Dynamite, he explains, blasts the rock out in sharp, angular chunks. “The aborigines pounded the rock out in little pieces, leaving a much smoother look to the mine pits,” he says.

The mines “are, for the most part, merely irregular depressions in the soil, trenches, pits, and cavities; sometimes not exceeding one foot in depth, and a few feet in diameter.

The layers of rock at one time laid like this,” Ruutila says, placing his one hand over the other like a sandwich. “Then they tilted,” he says, and tilts his hands. What we are standing on now is the edge of one of the tilted layers. When the land tilted, it opened cracks deep in the earth that allowed super-heated steam to rise, and when it did, it carried minute quantities of dissolved copper.

Lamsa wonders what they mean. Are they art? Are they some sort of communication? Lamsa pauses and looks around. “They say there are 5,000 mine pits between here and Copper Harbor,” he says. “But I’d say there’s 5,000 right around here.”

So I had stood where the ancients had stood. I had hefted their hammerstones, held their spear tips. But al...
