Bronze is the defining metal of the European Bronze Age and has been at the center of archaeological and science-based research for well over a century. Archaeometallurgical studies have largely focused on determining the geological origin of the constituent metals, copper and tin, and their movement from producer to consumer sites. More recently, the effects of recycling, both temporal and spatial, on the composition of the circulating metal stock have received much attention. Also, discussions of the value and perception of bronze, both as individual objects and as hoarded material, continue to be the focus of scholarly debate. Here, we bring together the sometimes-diverging views of several research groups on these topics in an attempt to find common ground and set out the major directions of the debate, for the benefit of future research. The paper discusses how to determine and interpret the geological provenance of new metal entering the system; the circulation of extant metal across time and space, and how this is seen in changing compositional signatures; and some economic aspects of metal production. These include the role of metal-producing communities within larger economic settings, quantifying the amount of metal present at any one time within a society, and aspects of hoarding, a distinctive European phenomenon that is less prevalent in the Middle Eastern and Asian Bronze Age societies.

ZusammenfassungIst es möglich, die Bronzezeit im Sinne der soziologisch definierten Begrifflichkeit “Globalisierung” zu fassen? Der Beitrag folgt dieser Fragestellung auf analytischem Wege, aber auch in der Diskussion ihrer Merkmale auf Basis moderner und zeitgenössischer Geschichtsschreibung. Sichtbar wird, dass die Bronzezeit als einzigartiges Beispiel der Verschränkung eines kontinentübergreifenden afrikanisch-eurasischen Großraumes anzusehen ist, der sich um etwa 2000 v. Chr. herausbildete und um ca. 1200 v. Chr. wieder verschwand. Um die Bronzezeit als ein entsprechend globalisiertes Phänomen betrachten zu können, wurde der Begriff “bronzization” eingeführt, der die Bronze als entscheidende Ressource eines historischen Wandels über den Zeitraum von 800 Jahren fasst und in den Mittelpunkt der Forschung stellt.

The breakthrough of the Nordic Bronze Age (NBA) c. 1600 BC as a koiné within Bronze Age Europe can be historically linked to the Carpathian Basin. Nordic distinctiveness entailed an entanglement of cosmology and warriorhood, albeit represented through different media in the hotspot zone (bronze) and in the northern zone (rock). In a Carpathian crossroad between the Eurasian Steppes, the Aegean world and temperate Europe during this time, a transcultural assemblage coalesced, fusing both tangible and intangible innovations from various different places. Superior warriorhood was coupled to beliefs in a tripartite cosmology, including a watery access to the netherworld while also exhibiting new fighting technologies and modes of social conduct. This transculture became creatively translated in a range of hot societies at the onset of the Middle Bronze Age. In southern Scandinavia, weaponry radiated momentous creativity that drew upon Carpathian originals, contacts and a pool of Carpathian ideas, but ultimately drawing on emergent Mycenaean hegemonies in the Aegean. This provided the incentive for a cosmology-rooted resource from which the NBA could take its starting point.

The rich and long-lasting Nordic Bronze Age was dependent throughout on incoming flows of copper and tin. The crucial turning point for the development of the NBA can be pinpointed as the second phase of the Late Neolithic (LN II, c. 2000–1700 BC) precisely because the availability and use of metal increased markedly at this time. But the precise provenance of copper reaching Scandinavia in the early second millennium is still unclear and our knowledge about the driving force leading to the establishment of the Bronze Age in southern Scandinavia is fragmentary and incomplete. This study, drawing on a large data set of 210 samples representing almost 50% of all existing metal objects known from this period in Denmark, uses trace element (EDXRF) and isotope analyses (MC-ICP-MS) of copper-based artifacts in combination with substantial typological knowledge to profoundly illuminate the contact directions, networks and routes of the earliest metal supplies. It also presents the first investigation of local recycling or mixing of metals originating from different ore regions. Both continuity and change emerge clearly in the metal-trading networks of the Late Neolithic to the first Bronze Age period. Artifacts in LN II consist mainly of high-impurity copper (so-called fahlore type copper), with the clear exception of British imports. Targeted reuse of foreign artifacts in local production is demonstrated by the presence of British metal in local-style axes. The much smaller range of lead isotope ratios among locally crafted compared to imported artifacts is also likely due to mixing. In the latter half of Nordic LN II (1800–1700 BC), the first signs emerge of a new and distinct type of copper with low impurity levels, which gains enormously in importance later in NBA IA.
