Injuries on a skull from the Ancient Bronze Age (Ballabio, Lecco, Italy): a natural or an anthropic origin?

This paper discusses the results of the analysis of a female skull from a collective burial dated to the Ancient Bronze Age in Italy (Ballabio, LC). A virtual restoration and 3D reconstruction was also produced from the digitalized skull to complete the damaged parts and to recreate the facial appearance of this young adult female from the Bronze Age. The skull shows clear evidence of post-mortem modifications, as some series of scraping marks on the external cranial vault cross the parietal bones longitudinally. The contemporaneous presence of taphonomic linear marks on the skull and periostitis on the frontal bone, as well as the provenance of the specimen from a secondary burial (a typical funerary habit documented in Italy during the Copper Age and Ancient Bronze Age), makes it difficult to interpret the case (scalping, surgery, or ritual practice linked to secondary burial). The advanced methods used to analyse the skull surface allowed us to discriminate intentional marks from modifications due to other taphonomic processes and to determine the timing of their formation (peri- or post-mortem). The possibility that the scraping marks are related to a ritual practice, conducted during the individual's life (with specific symbolic or social value) or after death or at the moment of secondary burial, is discussed.

► The biological profile of an individual from the Italian Bronze Age is presented.
► The significance of the injuries on the skull is discussed.
►  Stereo-microscopy and SEM were used to analyse the skull.
► Intentional scraping marks were distinguished from those of non-human origin.
►  Lesions may be due to ritual practice during the individual's life or after death.
