Jan Bartek – AncientPages.com – In a brand new examine, researchers investigated as many as 48 Nuragic collectible figurines (so-called bronzetti) and three copper bun ingots. These objects originate from three distinguished Sardinian sanctuaries and one unidentified website, courting to the late Nuragic interval of the early first millennium BCE.

Every of those locations is thought for producing bronzetti, normally depicting warriors, gods, and animals, Attention-grabbing is that the steel used at these websites was remarkably related. This discovering suggests a standardized method to the manufacturing of those objects throughout the island, which implies that the traditional communities shared approach or supply of supplies.
The Nuraghe tradition thrived in Sardinia in the course of the Bronze Age. It’s characterised by its distinctive tower-like stone constructions generally known as nuraghes.
The tradition’s bronzetti collectible figurines have lengthy captivated scientists, however the exact origin of their steel composition nonetheless stays unidentified.
The warior bronzetti from Abini, central Sardinia. Most bronzetti are proven with a weapon set consisting of differnet mixtures. This bronzetti is a part of the archer group and contains a sword, bow, arrows, and parts of physique armour, together with the standard horned helmet. These horned helmets are worn by warrior statuettes. Picture credit score: Heide W. Nørgaard with permission of the Museo Archaeologica Nazionale di Caglairi.
To find out the origin of the copper in these figures, the analysis workforce employed used a multi-proxy method, a way includes a mix of assorted chemical analyses. This system enabled them to match isotopes of copper, tin, lead, and a much less frequent isotope, osmium, to realize a clearer understanding of the metals’ sources. This technique has efficiently addressed a longstanding thriller that has lengthy challenged researchers.
In response to Daniel Berger, the primary writer from the Curt-Engelhorn Heart for Archaeometry who developed this new technique, the findings point out that bronzetti have been primarily crafted utilizing copper sourced from Sardinia. Often, this was mixed with copper from the Iberian Peninsula, which incorporates present-day Spain and Portugal. The examine additional revealed that copper from the Levant—areas akin to Timna in Israel and Faynan in Jordan—was not utilized in Sardinia.
This conclusion was reached by an evaluation of osmium isotopes.
“Archaeological strategies set up a robust basis that the most recent scientific strategies can refine and clarify. This may convey the previous discussions to a detailed. In our case, the newest geochemical information signifies the origin of the steel in particular geographical areas and sure mines. It’s also potential in a number of circumstances to hint a strategic mixture of copper with completely different origins. Presumably to realize sure results such because the product’s color and power,” says Professor Helle Vandkilde from Aarhus College.
A bronzetti picturing one other type of warrior discovered within the sanctuary of Santa Vittoria di Serri in central Sardinia. This warrior sort is simply proven with a dagger and has an extended, vast cloak. The fingers of this bronzetti are damaged; nonetheless, primarily based on related bronzetti, it might need proven the open hand gesture. Picture credit score: Heide W. Nørgaard with permission of the Museo Archaeologica Nazionale di Caglairi.
It’s fascinating that regardless of Sardinia’s native sources of tin and lead, these sources weren’t employed within the manufacturing of the collectible figurines. The tin required for bronze manufacturing was possible imported, presumably from the Iberian Peninsula. This conclusion is supported by the isotope signatures present in bronzetti and the chemical composition patterns noticed in Sardinian tin objects.

Analyzing the well-known bronze figures from Sardinia is essential for understanding the island’s position within the Bronze Age steel commerce. Their design suits the interval’s materials tradition, but it additionally options stylistic parts acquainted to southern Scandinavia.
The Viksø helmets and the depictions of warriors on petroglyphs sporting horn-adorned helmets provide helpful insights into the Scandinavian historical past. Latest discoveries concerning the origin of the steel are serving to researchers hint connections between Sardinia and Scandinavia, in line with Affiliate Professor Heide Wrobel Nørgaard.
