Technology, Ideology and Environment : The Social Dynamics of Iron Metallurgy in Great Zimbabwe, AD 900 to the Present
Abstract: This thesis provides insights into the nature and organization of iron technology associated with past and present communities of Great Zimbabwe in southern Africa. Written accounts, ethnographic enquiries and, results of archaeological field surveys and excavations are combined to provide the first detailed account of Great Zimbabwe’s iron production technologies. The existence of a considerable iron industry in Great Zimbabwe with complex and innovative designs and processes of iron smelting is established. Evidence includes tap slags, natural draft furnaces, one with a unique rectangular morphology, and the exploitation of manganese-rich iron ores or fluxes. Moderate to low levels of iron oxide in slag samples point to large-scale production of good quality iron for an extensive market at some time in the past of Great Zimbabwe. Iron slags, possible bloom pieces and broken tuyeres are examined using standard archaeometallurgical laboratory techniques to establish the decisions and choices underlying technology and pyro-metallurgical processes in and between sites. The results are explained using theoretical concepts of social practice and agency to address the worldviews, social values and beliefs of iron related practices in Great Zimbabwe over time.The study provides an alternative angle for approaching the social complexity of Great Zimbabwe (with its peak in the 12th–16th centuries AD), previously understood from the perspective of its spectacular architecture. Evidence of primary and secondary production activities in domestic and specialized settings outside settlements suggests a greater spatiotemporal complexity and ambiguity of the organization of technology than previously thought. Iron production in domestic contexts provided an inclusive space, creating the possibility for transformation of not just materials, but also women and children into social agents of technology, adding an alternative and more socially embedded perspective of technology in Africa.
