We present the Mummy Project of the Hellenic Institute of Egyptology (HIE), in close collaboration with the National Archaeological Museum of Athens (NAM) and the Athens Medical Centre (AMC), as a characteristic case of interdisciplinary study and interaction, not only between Smart Informatics (SI)-and to a lesser extent Artificial Intelligence (AI) and (Archaeo-)Medicine, but also with Egyptology and (Archaeo-)Forensics. We discuss some intriguing results of the CT-Scanning for five out of the nine mummies of the Project and emphasize the Informatics used for Computed Tomography (CT) that opens new ways in the study of the conditions, causes of death and other interesting information connected with humans who died in ancient Egypt at least 2,100 years ago, during the Ptolemaic Era. We show clearly that this consists of a characteristic paradigm of interdisciplinary SI application in Medicine and the health of ancient individuals (based on Smart Computing), providing new insights into the egyptological and archaeological consideration of their theocratic society.
