CT Scans in Art Work Appraisal
C. CT: a flattened view of the dog’s body, following the movement of the curved arrow, which confirms the juxtaposition of different terracotta slabs.
D. CT: inclined 3D views of the inner wall of the dog’s body. It shows that the terracotta has been scraped out to ensure that the weight of the finished sculpture is comparable with that of an antique piece. There are also dribbles of cement (arrows) on the inner curves of a trapdoor cut in the animal’s back. Indeed, although the inside of the head and the neck could be reached through the open mouth, a temporary trapdoor had to be cut out so that a scraper could be inserted into the dog’s belly.
