A Multidisciplinary Study of Egyptian Mummies from the Pushkin State Museum of Fine Arts (Methodical Aspects)

We present the results of a multidisciplinary study (the fi rst one in Russia) of nine Egyptian mummies owned by the Pushkin State Museum of Fine Arts (Moscow), carried out at the Kurchatov Institute. A detailed description of the methods is provided. X-ray computed tomography is shown to be a highly informative non-destructive technique for studying the 3D structures of mummies. On the basis of the results, plus the conclusions of forensic experts, a detailed anthropological analysis was conducted. Mummifi cation techniques, sex, and age of all individuals were assessed. In three cases, the sex differed from that indicated in the museum inventory. Morphologically, all crania represent varieties of the Mediterranean type. One individual, however, has typically sub-Saharan features. Pathological changes concern mostly the spine and are both age-related and traumatic. In two individuals, spinal pathologies might have caused death.

Investigation of the archeological remains using ultrahigh resolution mass spectrometry

Investigation of the archeological material at the molecular level can reveal the composition of ancient paint, balsamic material, reveal cooking recipes, etc. High-resolution mass spectrometry is a powerful technique with underestimated potential for archeology. Here, we present the investigation of the 3000-year-old archeological remains, identified as parts of internal organs of an Egyptian mummy, using high-resolution Orbitrap mass spectrometry. We observed a diverse number of oxidized classes of compounds: O, O₂, O₃, O₄, O₅, N, NO, NO₂, NO₃, NO₄, NO₅, N₂O, N₂O₂. Such chemical composition is unusual and we never observed it in our previous studies of petroleum, humic substances, products of wood pyrolysis or other natural complex mixtures. It is possible that such compounds are formed via biodegradation of lipids and other organic material used for funeral rites. We did not observe evidence of the presence of mineral bitumen, although there are many historical records of the use of mineral bitumen for mummification.
