Archaeologists in Poland have uncovered a remarkable collection of Iron Age jewelry and artifacts made from meteorites, marking one of the highest concentrations of meteoric iron objects ever found. A study, led by Dr. Albert Jambon and published in the Journal of Archaeological Science: Reports, examined items from two Early Iron Age cemeteries in southern Poland, revealing that ancient metalworkers crafted bracelets and a pin from space-derived metal.
The discovery challenges previous assumptions about early metallurgy, suggesting that meteoric iron was actively collected and used alongside smelted iron. The artifacts offer a rare insight into how Iron Age craftsmen incorporated extraterrestrial materials into their work, expanding the understanding of early iron production.
Tracing the Origins of Iron Smelting
For centuries, archaeologists have debated when and how iron smelting began. Did it evolve gradually, or was it independently discovered in different regions? Answering this question requires distinguishing meteoric iron from smelted iron in ancient artifacts, a process that involves precise chemical analysis.
“The goal of my research is to determine who, when, and where iron smelting was discovered,” explained Dr. Jambon. “To achieve this, we analyze archaeological iron objects to establish whether they are of meteoritic or smelted origin.”
The Polish artifacts were recovered from two cemeteries associated with the Lusatian Culture, dating from 750 to 600 BCE. Excavations at the Częstochowa-Raków and Częstochowa-Mirów sites yielded 26 iron objects, including bracelets, ankle rings, knives, spearheads, and necklaces. Advanced scientific techniques such as portable X-ray fluorescence (p-XRF), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), and X-ray microtomography identified four items as containing meteoric iron.
Meteorite Connection: Evidence of a Witnessed Fall?
One of the most intriguing aspects of the discovery is that the meteoric iron appears to have come from a single source—an ataxite meteorite, a rare, nickel-rich type of space rock. Due to its high nickel content, ataxite is difficult to work with, raising questions about how Iron Age metalworkers acquired and shaped the material.
Dr. Jambon suggests that the presence of multiple meteoric iron artifacts in one location indicates the iron was obtained from a witnessed meteorite fall rather than a random discovery. “There is a high likelihood that people observed the meteorite fall rather than stumbling upon it by chance,” he stated. “Iron meteorites can be large, sometimes hundreds of kilograms, but large pieces are not easily workable. Small fragments, under one kilogram, are needed, and these are difficult to separate with Iron Age tools.”
He compared this to historical meteorite falls, such as a 600-kilogram iron meteorite found in France in 1830. Despite efforts to extract usable pieces, the metal proved too hard, and the attempt was abandoned. In the case of the Polish artifacts, the presence of small, workable fragments suggests the meteorite was collected soon after impact, before natural elements buried it.
Meteoric Iron: A Common Material, Not a Luxury
Surprisingly, the study found that meteoric iron did not hold special prestige in Iron Age society. Unlike gold or silver, which were reserved for the elite, meteoric iron objects were discovered in the graves of men, women, and children alike. None of the burials contained gold, silver, gemstones, or imported goods, suggesting meteoric iron was valued similarly to regular iron.
“During the Bronze Age, iron was about ten times more expensive than gold,” noted Dr. Jambon. “But by the early Iron Age, its value dropped drastically to below that of copper.”
This decline in value likely resulted from the increasing availability of smelted iron, which by 750 BCE had become the primary metal for tools and weapons. While iron had been rare and valuable during the Bronze Age, Iron Age societies transitioned to large-scale production, reducing reliance on meteoric sources.
The findings provide new insights into how ancient civilizations adapted to technological advancements and resource availability. They also highlight the ingenuity of early metalworkers, who skillfully utilized both terrestrial and extraterrestrial materials to craft everyday objects.
