Ethnoarchaeological research combined with morphological analysis of modern and ancient grinding stones was completed in 2013 and 2014 as part of the Eastern Tigrai Archaeological Project (ETAP), based in the Gulo Makeda region of northern Ethiopia. Research focused on investigating the cultural context of grinding, grinding stone morphology, and use-surface area employing low power use-wear analysis of grinding surfaces. In the Gulo Makeda region today, men manufacture grinding stones and women use them in food processing for many hours per day. While grinding, relationships are formed and maintained with other women, and archaeological evidence suggests that women were grinding together in the past. It was discovered through interviews that distinctive grinding surfaces are preferred for processing different cereals based on grain size. Rough surfaces are used to process larger grains such as imported Near Eastern barley (Hordeum vulgare), wheat (Triticum spp.), maize (Zea mays), and the African domesticate sorghum (Sorghum bicolor), while fine/smooth surfaces are used for smaller, locally domesticated African grains including finger millet (Eleusine coracana) and t’ef (Eragrostis tef). Comparing ethnoarchaeological data with evidence of different use-surfaces on ancient Mezber grinding stones suggests that both locally domesticated and imported grains have been processed in the region for thousands of years. Interpretations are made about the use of grinding stones in the past through analogy, supported by evidence of ancient stone tool morphology and surface wear. The archaeological record at the pre-Aksumite site of Mezber indicates that grinding stone sizes have changed through time, with larger grinding surface areas likely reflecting the need for the production of greater amounts of flour.  相似文献
