Seeing is believing – The application of Three-Dimensional modelling technologies to reconstruct the final hours in the life of an ancient Egyptian Crocodile

Abstract

The application of non-invasive radiography (X-ray and CT) to an ancient Egyptian crocodile mummy demonstrated a high level of corporeal preservation achieved through artificial embalming. Analysis revealed numerous anomalies within the abdomen of the crocodile which merited further investigation using digital three-dimensional modelling technologies. Improving the clarity of the CT scan data enabled the authors to identify the anomalies which included a metal fish hook and a small fish. Segmentation of the CT scan data enabled the virtual extraction of the hook from within the confines of the mummy and its replication, firstly in plastic and then in its original material, bronze.Through the scientific analysis of the mummy, the authors reconstruct the biological biography and life history attributes of the animal, and consider the human-animal relationships and religious beliefs behind its post-mortem preservation. The study explores the application of the 3D technologies applied to archaeological materials and the novel implementation of experimental techniques to reproduce the anomaly. The investigation provided the ability to enhance the study, interpretation and display of the mummy; a matter of particular relevance in the case of mummified remains where anomalies are not directly visible. The authors consider the improved accessibility to cultural artefacts made possible through the application of enhanced visualisation techniques in the heritage sector.
