Acknowledged authenticity. Or did the origin of rock matter in the Mesolithic?

Abstract This article explores the concept of authenticity of rock, place and stone tools in the Mesolithic. It uses results from a recent pXRF analysis on a selection of greenstone adzes predominantly originating from a delimited area on the western coast of south Norway as its point of departure. The results show that, although the majority of the 80 analysed adzes were made of greenstone from one specific source, eight clearly stemmed from local outcrops away from this one source area. The quantitative geochemical data are not presented in detail. Instead, the focus is on the social significance of these stone objects and their sources as indicated by the results. I argue that the anomalies demonstrate an acknowledged social value placed on stone from a dedicated source area; they represent deliberate attempts to manipulate perception and thus replicate a specific social affinity. Emphasizing perception and appearance, I consider adzes of green stone as assemblages of knowledge, skill, place and social memory – as desirable objects that enhanced a feeling of belonging and social identity – and I question whether this means that people in the Mesolithic recognized and acknowledged something as authentic.
