A 4,000-year-old copper dagger has been unearthed in the forests near Korzenica, southeastern Poland. It is the oldest metal dagger discovered in the Subcarpathian Voivodeship.

The dagger, measuring 10.5 cm in length, was found by Piotr Gorlach of the Historical and Exploration ᴀssociation Grupa Jarosław during a routine metal detector survey in Jarosław Forest.

Initially searching for military artifacts from World War I or II, Gorlach stumbled upon the ancient weapon as he was about to conclude his expedition. “I had already finished my search for the day. When I returned to the car, I left the detector on out of habit. At some point, there was a signal. When I was digging up the forest floor, I saw a flat metal object covered with a green patina. I quickly realized that I was dealing with something much older than the military items from World War I and II that I was looking for in this area,” Gorlach recounted.

The significance of the find prompted Gorlach to contact the authorities, leading to collaboration with the Podkarpacie conservator of monuments in Przemyśl and the Orsetti House Museum. Archaeologists quickly identified the artifact as an exceptionally rare 4,000-year-old dagger, marking a significant milestone in the region’s history.

Dr. Elżbieta Sieradzka-Burghardt from the Museum in Jarosław elaborated on the importance of the discovery, stating, “In the 3rd millennium BC, objects made of copper were extremely rare in these areas.” This rarity underscores the high social status of the dagger’s owner, as copper items were exclusive to elites during this period.

Further analysis suggests that the dagger may have originated from the Carpathian Basin or Ukrainian steppe, predating the widespread use of bronze metallurgy in the region. Dr. Marcin Burghardt, also from the Jarosław museum, contextualized the find within the broader transition from stone to metal tools, marking the dawn of the Bronze Age. “Instead of flint tools commonly used in the Stone Age, more and more metal products appear, heralding the transition to the next period – the Bronze Age,” noted Dr. Burghardt.

While daggers were ubiquitous among warriors during this era, the use of copper for such a weapon highlights its owner’s status. Dr. Sieradzka-Burghardt emphasized the rarity of copper objects during this period, suggesting that the dagger’s origins lay beyond the local region. “There is rather no doubt that the dagger is not a local product,” she remarked.

The discovery adds a significant piece to the puzzle of early metalworking in Central Europe. Plans are underway to display the dagger at the Orsetti House Museum.
