The Cross & the Crucible: The Production of Carolingian Disc Brooches as Objects of Religious Exchange?

Abstract

In this article, aspects of the production and exchange of Carolingian/Ottonian disc brooches are examined through an analysis of 281 brooches selected from collections across The Netherlands. The composition of the brooches was measured with a Hand Held-XRF device and the results showed a sharp deviation from the alloys seen in brooches from earlier periods. The results across all geographic areas consisted of a mixture of copper, zinc and lead, but no tin. If recycling practices were present in the making of these brooches, then you might expect an element of tin to enter the mixture, as bronze items entered the alloy-recycling stream. But this appears not to be the case. This consistency rules out production by travelling merchants, or at domestic households and primitive workshops. The results suggest that production was more likely organised on a regional or even super regional scale. An analysis of production at royal estates, emporia and the great abbeys found the latter to be the most likely source of these objects. Furthermore, the Christian nature of these brooches, if produced within monastic centres, may have imbued them with religious meaning, allow for a fresh interpretation of their methods of exchange.
