Reconstructing prehistoric metallurgical knowledge: the northern Italian Copper and Bronze Ages

Abstract

The paper attempts to integrate the results of chemical analyses, which are seriously underused in archaeological discourse, with other classes of information in order to try to interpret ancient metal working behaviour and knowledge within a semiotic framework, adopting the modernist premise that ancient metalworking was both rational and deliberate. A number of case studies from northern Italy is discussed. In the first it is noted that in the Copper Age Remedello culture arsenical copper was used for halberds and daggers while purer copper was used for flat axes; it is suggested that this distinction reflects deliberate choice and explanations are offered for it. The second case study regards the interpretation of the Pieve Albignola early Bronze Age axe hoard; evidence for the workshop practices of ancient bronzesmiths and for the use of axe preforms as ingots is discussed. The third case study concerns the swords and daggers of the middle and recent Bronze Age; finds context (tombs and wetlands) are discussed and it is suggested that metal analyses may indicate that sometimes these artefacts are not primarily functional.
