Humankind is believed to have existed in Africa for over 6 million years, based on the dating of excavated fossils. Transformations took place over time in response to severe climate changes and the Modern Human, believed to be the first to spread beyond Africa evolved only about 2 million years ago and did not move to other parts of the world until about 200,000 years ago. What is now known about ancient human history came from several sources: paleontologists excavate and evaluate human and article fossils dating back 2-3 million years; archaeologists excavate ancient sites and study recovered articles, mostly dating back 40-60,000 years; historians study oral and recorded history but the scope is limited to about 3,000 years when writing was invented. Archaeometallurgy evolved in the second half of the last century and has become a major tool for the study of ancient metals, metalworking structures, tools, waste products and finished artifacts, using techniques from the physical sciences. While this does not in anyway distract from the traditional approach of other archaeoscientists, it is a very valuable complement, since it provides in-depth information about ore and slag composition, furnace design, macro and micro analysis of objects, all of which give vital information about the probable production techniques. Materials have played a central role throughout human history, starting with stone, flint, wood, straw, and transitioning to metals around ten to twelve thousand years ago. In fact the major stages of historical evolution are delineated by the materials that were in prominent use: Stone Age; Bronze Age; Iron Age, etc. If Africa is indeed the cradle of humankind, then it should have a very rich archaeohistory but most of the discoveries so far have been accidental. This book presents the results of a comprehensive study of the rich early archeometallurgical history of Nigeria which dates back to around 800 BC, in the context of early world metallurgy. Issues treated include probable socio/ethno cultural settings, practices in the context of early world metal cultures, provenance of technologies, and local technological innovations.
