The metal alloy of a life-size Roman statue was determined using high-energy Proton Induced X-ray Emission (PIXE). In addition to the non-destructive PIXE measurements, it was also possible to take samples from inside the statue, which were analysed using atomic absorption spectroscopy (AAS). The results of the high-energy PIXE measurements are presented and compared to the AAS results. The reasons for differences and the difficulties obtaining accurate compositions of antique objects are discussed.
