Łukasz Jabłoński was scouring a field in Poland with his metal detector when he made an unusual discovery.
About eight inches underground, Jabłoński found a trove of 13 bronze artifacts, according to a June 16 news release from Science in Poland, a subset of the national news agency.
Experts identified the artifacts as dating back about 2,500 years to the Lusatian culture, specifically toward the end of the period between 550 B.C. and 400 B.C. Previously, archaeologists had only found a few individual artifacts from the time period, so Jabłoński’s find marks the first time a whole set of items has been discovered.
Among the finds, archaeologists identified two pins that are approximately six inches long, a decorative shield to attach to clothing, two circular pieces of leg armor and six bracelets, according to Science in Poland.
Jabłoński told Science in Poland the discoveries are of “great cognitive, scientific and conservation importance for archaeologists, in the context of analyzing the settlement of this culture in this region, as well as in the entire Lublin region.”
Experts said they kept the discovery a secret until now to ensure they could protect the field — which is in Czerniaczyn Poduchowny — from illegal excavations. The bronze artifacts are at the Museum of the Biłgoraj Land for further preservation and analysis.
Czerniaczyn Poduchowny is about 145 miles southeast of Warsaw.
