This paper reports on the investigation of metal finds from the wreck of a Punic ship, using techniques such as portable X-ray fluorescence and Raman spectroscopy to identify their composition. The degradation of these finds in the underwater environment was also explained through the analysis of micro-samples using X-ray diffractometry, polarised optical microscopy, and scanning electron microscopy.
The wreck of the Punic ship exhibited at the Archaeological Park of Lilybaeum (Marsala, Italy) is a unique example in the world. In this paper, the investigation of some metal finds (30 nails and 3 fragments of sheathings) belonging to the wreck of the Punic ship is reported. Portable X-ray fluorescence and Raman spectroscopy allowed us to identify the elements and compounds constituting them and make some deductions about their composition. X-ray diffractometry, polarised optical microscopy and scanning electron microscopy of the collected micro-samples allowed us to explain the degradation that occurred in the underwater environment.
