Owing to its well‐preserved and long‐lasting archaeological record, the necropolis of Petit‐Chasseur in the Upper Rhône Valley (3100–1600 BC) showcases the economic, social, and ideological changes of 3rd and 2nd millennium BC Europe excellently. An in‐depth investigation of pottery artifacts was carried out using multiple spectroscopic and microscopic techniques. Nine types of ceramic fabrics were identified based on the variety of temper and natural inclusions; however, the mineralogy and phase chemistry of the ceramic matrix showed the paste to be primarily illitic or muscovitic, irrespective of the inclusion type. Muscovitic clays were likely procured from the fluvioglacial, glaciolacustrine, colluvial, and till sediment abundantly available at higher altitudes of the Upper Rhône Valley, whereas illitic clays were acquired from pedogenized loess horizons or the Rhône River alluvium. Different raw material choices and paste preparation practices suggest distinct ceramic traditions that likely existed in the valley during the 3rd and 2nd millennia BC. This, along with the hypothesized provenance of the raw material, is likely in favor of various prehistoric communities gathering at the megalithic necropolis from close and distant parts of the valley using the Petit‐Chasseur site as a place of assembly.
The Petit-Chasseur megalithic necropolis is a key archaeological context for analyzing the social and ideological changes at the end of the Neolithic in the Alpine region of Central Europe. The link between the funerary monuments and settlement sites was established by means of ceramic archaeometric analysis. Domestic pottery from settlement sites were thoroughly characterized using multiple spectroscopic and microscopic techniques. Twelve ceramic fabrics were identified along with three types of clay substrate: illitic, muscovitic, and kaolinitic. Reconstructed paste preparation recipes largely involved the tempering of the raw clays with crushed rocks or coarse sediments. Types of raw material were not picked up randomly but were selected or avoided due to their particular compositional properties and attest to the exploitation of glacial, gravitational, eolian, and fluvial deposits. Compositional correspondence between ceramic grave goods and domestic pottery allowed identification of a link between the megalithic tombs and settlement sites, thus providing new data contributing to the investigation of the social dimension of monumental burials. Ceramic grave goods were revealed to be intertwined with the social instability affecting the 3rd millennium BC communities of the Upper Rhône Valley.
Through the analyses of recovered pottery, this study explores the social dimension of an ancestor cult developed at the Petit-Chasseur megalithic necropolis (Upper Rhône Valley, Switzerland) during the Early Bronze Age (2200–1600 BC). The jar votive offerings and domestic pottery from settlement sites were characterized using a range of spectroscopic and microscopic techniques. Acquired archaeometric data allowed identification of six ceramic fabrics and two types of clay substrate—illite- and muscovite-based—which were used in pottery production. The present article discusses the pottery composition in the light of natural resources available in the region, thus shedding light on raw material choices and paste preparation recipes. The Early Bronze Age people that lived in the Upper Rhône Valley seem to have shared a common ceramic tradition, partly inherited from the previous Bell Beaker populations. The compositional correspondence between the jar offerings and domestic pottery revealed that the majority of the known Early Bronze Age groups partook in cultic activities at the Petit-Chasseur megalithic necropolis.
