It is well known that neutron imaging is a powerful nondestructive technique in archaeological studies, especially for visualization of organic contents or low-density parts inside antiques. In Thailand, the neutron imaging system has been developed to perform neutron tomography (NT) for archeological studies since 2015. A compact NT system, which is composed of a CCD camera coupled with a LiF/ZnS fluorescence screen and an in-house developed rotation stage, was used to investigate the internal structure of an object. The experiment was set up at Thai Research Reactor (TRR-1/M1) of Thailand Institute of Nuclear Technology (Public Organization) with the power of 1.2 MWth. The neutron intensity at the radiographic position was about 10 6 n.cm -2 s -1 . In this work, an ancient sample of interest, namely, the 15 th -18 th century terracotta doll was investigated to perform the developed NT system. The resulting 2D neutron image showed a crack at the neck and a small gravel inside the body. Then, the projections were reconstructed by means of the Octopus Imaging software. Even with the compact NT system (L/D: 50), the 3D neutron image of the ancient doll was successfully reconstructed. The image revealed some hidden organic materials coated on the neck of the doll. Moreover, the elemental composition of the terracotta doll was analyzed by using X-ray fluorescence technique. The result could further inform the historical records of the ancient doll.
In 2021 the Chau Chak Wing Museum, University of Sydney, received a new donation of an Egyptian shabti in a model coffin. It was given to the donor’s grandfather by the Sixth Earl of Carnarvon in gratitude for the safe return of artifacts accidentally left in an item of furniture sold through a London auction house in the mid-1920s. The shabti was originally discovered by the Earl’s father during his excavations of the Theban Valley, in the tomb of Tetiky, an important administrator of the early New Kingdom. This paper presents the curatorial investigation of the artifact’s provenance, contextualizes the artifact as part of an assemblage that is dispersed globally in museum collections, and determines how it came to be hidden in a cupboard. This paper hopes to serve as a case study in recontextualizing archaeological artifacts as part of dispersed assemblages in multiple collections through detailed interconnected provenance studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
