The Bronze Age Levels of the Eremita Cave in Piedmont (Italy): First Chronological and Cultural Data

Abstract

This article presents the first results of the planned archaeological excavations led by Prof. Marie Besse, head of the Laboratory of prehistoric archaeology and anthropology of the Department F.-A. Forel for environmental and aquatic sciences of the University of Geneva, at the Eremita Cave site between 2012 and 2015. The Eremita Cave is located in the North Italian region of Piedmont, in the heart the calcareous massif of Monte Fenera, near Borgosesia (Vercelli). The Monte Fenera is already well known for its numerous caves, many of which contain archaeological remains chronologically spanning from the Palaeolithic to the Middle Ages. This particular situation can be explained by two elements: the uniqueness of the massif from a geological perspective when compared to the rest of the area, and its strategic localisation on the southern alpine foothills, that made it a possible stopover for the people transitioning the Alps. The interest of the researchers of the Laboratory of prehistoric archaeology and anthropology was sparked by the mention of the discovery of a bone button attributed to the “età del Rame” (Copper Age) in the Eremita Cave in the late 1980s by the Gruppo Archeologico e Speleologico di Borgosesia (GASB). The first test trenches confirmed the importance of this archaeological site with the uncovering of a pin and spiralled pearls in bronze in the middle of the cave. Further excavations began in 2013. They allowed the team to point out to two important levels. The first one being US 10, a thin silty level that contains numerous lumps of coal. The second is US 19, a level identified around 40 cm below US 10. It delivered a great amount of animal remains, mostly burned, in association with potsherds and stone blocks, and most importantly bronze finery. Four charcoal samples were sent for radiocarbon dating to Zurich (ETH), one belonging to US 10, one to US 19 in the back of the cave, and two to US 19 around the place of discovery of the pin and pearls. The results showed that US 10 is dated to the Late Bronze Age (ETH-64659, 1013-850 cal BC), and US 19 to the earliest stages of Middle Bronze Age (ETH-64657, 1767-1627 cal BC). They also confirmed that the stratigraphy of the cave was undisturbed. Culturally speaking, the shape of the pin shows affinities with the North of the Alps, while the pottery shapes display similarities with the common cultural ground of the alpine region, mostly Valais and Piedmont. Excavations are being carried on by the University of Geneva. The researchers are aiming at determining the function of the cave, mainly by studying the location of the archaeological structures and remains but also by linking the spatial distribution of potsherds to the reassembled pottery. The typological and technological analysis of the pottery assemblage should allow us to establish the cultural affiliations of the site.
