In accordance with ancient Egyptian beliefs, the preservation of the body after death was an important prerequisite for the continued existence of the deceased in the afterlife. This involved application of various physical interventions and magical rituals to the corpse. Computed tomography (CT), as the gold-standard technology in the field of paleoradiology, enables deeper insights into details of artificial body preservation. Therefore, CT was applied to investigate age at death, sex, mummification techniques, and the state of soft tissue preservation in 21 child mummies. The specimens are housed in European museums and were found in various archaeological sites. This sample included 12 males, 7 females, and two specimens of unknown sex, all between the ages of one and 14 years. Time periods were determined by radiocarbon dating, and time-related indicators of funerary equipment and decoration. Most of the mummies date from the Late Period to the Roman Period (664 BC-395 AD). Differences were identified concerning techniques of wrapping and embalming and removal of brain and internal organs, depending on age at death, social status and the archaeological site of the individuals. The variety and multifaceted nature of mummification and soft tissue preservation was analyzed in an integrated approach including a large number of specimens. The study highlights the significance of subadult remains as valuable bioarcheological archives to investigate burial customs and religious concepts in past societies., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Zesch et al.

Resins have been used as remedies since ancient times and various embalming resins have been identified in recent years. In Europe, Mumia vera aegyptiaca, a resinous substance from ancient Egyptian mummies, was even sold in pharmacies as a tonic until the early 20th century. It is difficult to examine the composition of these archeological samples in detail as the well-established analytical techniques, that is, gas chromatography-mass spectrometry or liquid chromatography coupled with tandem mass spectrometry, are destructive and therefore do not allow the analysis of valuable archeological samples. Hence, there is an urgent need for alternative, nondestructive methods for the identification of resin residues. This study aims to explore and compare the use of five spectroscopic methods as an alternative to established analytical procedures. For that, 15 resin samples of known origin and three samples from an Egyptian market were studied. While laser induced-breakdown spectroscopy and terahertz time-domain spectroscopy provide only limited information for resin classification, nuclear magnetic resonance spectroscopy and Fourier-transform infrared spectroscopy can be used to classify the resin samples more accurately. Furthermore, photoluminescence/photoluminescence excitation spectroscopy shows a promising potential in combination with its general advantages, such as cost-efficiency, nondestructive nature, and fast data acquisition., (© 2024 The Author(s).
