description Pulsed infrared thermography was applied to the analysis of the Capitoline She Wolf bronze statue, in the collection of the Musei Capitolini in Rome. We show how it can be used to study the bronze alloy properties and several subsurface and structural features of the statue such as casting faults and repairs providing information useful to recover the steps of the manufacturing process. In particular, the thermal diffusivity of the alloy was determined and quantitative evaluations were carried out concerning the thickness of the bronze in various parts of the statue, the depth of cavities originating from air bubbles in the casting melt and the profile of the contact area of some patches applied to mend gaps left after the casting process. Finally the obtained thermal diffusivity value was discussed in relation to the actual bronze composition of the She Wolf statue and it was shown to be consistent with the trend of values expected for different copper alloy compositions.
