Abstract:
Interpersonal violence in the past is studied from different perspectives, one of which is experimentation. Using analogues to the human skeleton it is possible to replicate fractures found in the archaeological record and understand how they were produced. The main objective of this paper is to describe and differentiate sharp-blunt force cranial trauma caused by stone axes and adzes, to test previous interpretations of an archaeological case. This will create a comparative frame of reference for future studies. In the present experiment, seven Synbone polyurethane spheres were used as analogues to the human skull. These were covered with rubber skin, filled with ballistic gelatin, and fixed in a way that allowed some mobility when struck. This system creates a skin-skull-brain-neck model. A replica of a stone axe and adze were used as weapon-tools, simulating a face-to-face attack. The results of the experiment showed that there are a series of characteristics that differentiate the fracture pattern associated with each one, confirming previous bioarchaeological interpretations. The differentiation between both weapon-tools through the resulting cranial trauma allows conclusions about the direction of the blow and the position of the attacker with respect to the victim. This provides a better reconstruction of the most likely scenario surrounding the confrontation and the possible cause of death of the individuals, which is especially important during the Neolithic period, when this type of cranial trauma is very common.
