Baubles, Bangles and Beads: Commodity Exchange between the Indian Ocean Region and Interior Southern Africa during 8th–15th Centuries CE

When material objects are recovered in a place different from their presumed place of origin, archaeologists usually fix attention on those objects and places themselves. Material objects do not, in themselves, however, have intrinsic value, and underlying the material variables of objects and their loci of origin and deposition is a more fundamental actuality of their translocation, the regimes of value in which things were assessed and in which they moved. Fundamental to this is that things have exchange value as well as consumption value and may also have spiritual value in specific circumstances. I argue that these are particularly important considerations when material objects are translocated from a distinct socio-geographic region, with its internal regime of values, to another quite different region, with probably diverse local regimes of value, as is the case when Early–Middle Iron-Age (300–1300 CE) sumptuary goods, mainly glass beads, moved from the East African Indian Ocean sphere to interior southern Africa, which had its own distinct regimes of value. In this article, I present data for this movement and premises regarding regimes of value, to address the trajectory of such beads into the southern region. I suggest that marine gastropod shells, cowrie and conus, are equally significant markers of interior–coastal associations, and their presence at 7th–11th-century southern sites with no glass beads suggests that different regimes of value were held by southern African peoples. This offers clues to bead and shell distributions. Several concrete instances demonstrate the point.
