A second stage of RTI recording was carried out in order to establish the depth of the suspected pock-marks. Figure 15 illustrates the results from this stage of analysis.
By now it is possible to see that the marks appear definitely to be a network of cavities. Moreover they are quite crudely punched and are of differing depths. In addition to this they appear predominantly to be angled upwards as though a mason was deliberately striking them onto the surface of the effigy from below. This begins to indicate that the effigy was already in situ when the marks were made rather than created in a studio, and this in turn could suggest that they were a secondary treatment.
