Histology is a technique that has any number of diagnostic uses in modern hospital laboratories. However, as a scientific method employed in the study of ancient and mummified remains, it appears to have lost its popularity.This project explores the advantages and limitations of histology as a technique for such studies. In order to do so, soft tissue and bone samples from ten early Roman Period mummies (30 BCE – 250 CE) from the Kellis 1 cemetery in the Dakhleh Oasis have been histologically examined.While this project focuses on the scientific technique of histology, and its application for the study of ancient remains, it also aims to be cross-disciplinary by incorporating scientific results from the ten mummies with the historical data and archaeological remains uncovered during excavations of the Kellis site. By bringing the results of science and Egyptology/archaeology together, it hoped that a better understanding of ancient Egyptian society could be achieved.

Devant les processus de décomposition, les sociétés humaines réagissent en pratiquant interventions culturelles de 'thanato-métamorphose' sur les cadavres, comme la momification. En Sicile nous trouvons une pratique de momification toute originelle (XVIe ÷ XIXe siècles), pratiquée par les moines des congrégations religieuses, qui se développe selon une série de variations locales. Elle est le fruit d’une longue et non définitive expérimentation, consistant dans une méthode empirique de dessiccation des dépouilles mortelles. Le procédé de conservation se déroulait dans les chambres souterraines annexées aux églises, pourvues des égouttoirs.  La momification reflétait des fonctions et idéologies précises, vivement lié aux possibilités économiques des individus, nécessaires pour maintenir le status économique et social d’appartenance. La lente disparition de la pratique de momification des corps remonte au l’édit de Saint-Cloud du 1804, qui marque l’interdiction législative d’inhumation des cadavres dans les églises et l’apparition des premiers cimetières extra moenia. Cependant, beaucoup d'éléments de la séculaire pratique de la momification survécurent. Les données recueillies nous poussent à penser que la momification fût une pratique bien enracinée dans le monde sicilien, et qu’après et malgré les décrets législatifs du 1804, elle ait 'survécu', en influençant l'enterrement et la relation avec la Mort jusqu'à nos jours. / Having to do with the processes of decomposition, the human societies react by practicing cultural interventions of 'thanato-metamorphosis' on bodies, as the mummification. In Sicily we find a practice of mummification really original (XVI th ÷ XIX th centuries), practiced by the monks of the religious congregations, which develops according to a series of local variations. This practice is the fruit of long and not definitive experimentation, consisting in an empirical method of dehydration of human remains. The process of conservation of bodies took place in the subterranean rooms annexed to churches, provided with colanders. The mummification reflected particulars functions and ideologies, deeply tied to the economic possibilities of the individuals, necessaries to maintain the economic and social status of belonging. The slow disappearance of the mummification’s practice goes up to the edict of Saint-Cloud of the 1804, which marks the legislative interdiction of burial’s bodies in churches and the appearance of first cemeteries extra moenia. However, many elements of secular practice of mummification have survived. By the informations gathered on mummification’s practice we think that the practice was well rooted in the sicilian world, after the legislative decree of the 1804, and that it has survived, by influencing to bury and the relation with the Death until our days.

Forensic anthropology, forensic taphonomy and forensic entomology are specialties that greatly contribute to judicial investigations and the identification of a decomposing corpse. This research examines the effect of calcium oxide (CaO), known as “quicklime”, on the decomposition process of human remains in a tropical climate. Quicklime has been used since the Early Iron Age, in wars, mass graves and today by criminals, as there is a belief or social myth that it can speed up the process of decomposition of bodies. However, there are no studies on the effect of this chemical on decomposing bodies in a tropical climate. Puerto Rico, in addition to having this climate, has a high crime rate related to drug trafficking. This study uses a series (n=10) of pig (Sus scrofa) burials as a model for human corpses, which were documented through photographs and state of decomposition, as well as climatic conditions, soil pH, odor of decomposition, and the lost mass. The author hypothesizes that the tropical climate contributes to the rapid decomposition of bodies by altering their appearance and morphology; since it is warmer, bacteria multiply more quickly and the entomofauna is more active, in comparison with studies already carried out in temperate climates. In addition, quicklime helps soft tissue decomposition proceed faster and reduces decomposition odor. Among the results, it was observed that there was no acceleration in the decomposition process due to the application of calcium oxide, and this chemical does not have the qualities attributed to it by social myths regarding the complete destruction of human remains, which could be considered an advantage for investigators in cases where there is a buried corpse covered in quicklime. However, it was possible to show that among other effects of quicklime, it subjectively reduces the odor of decomposition, inhibits and/or reduces the activity of the entomofauna, maintains a soil with an alkaline pH and therefore caused the mummification of the body. It can be suggested that the tropical climate helps in an effective decomposition due to the high temperatures, the humidity, and the activity of the entomofauna. Therefore, in both temperate and tropical climates, quicklime does not accelerate the decomposition process, but in a tropical climate it can inhibit the activity of entomofauna and the odor of decomposition. Statistically, results show that the Total Body Score (TBS) did not vary significantly, but the percentage of Mass Loss (ML) had a statistical difference due to the adhesion of the compacted quicklime to the experimental carcasses which increased the overall mass and not because a difference in the actual tissue loss was measured. This is since the decay process almost stopped after 77 days of burial and the mass loss nearly ceased, because with more days of rain and humidity, the more chemical reaction quicklime does (turning it into hydrated lime), causing solidification and mummification in the experimental pig carcasses. The quicklime also maintained an alkaline pH in the pig carcasses compared to the acidic pH of the controls after the decomposition. Therefore, quicklime causes a very sudden dehydration, and, in this sense, it prevents the proliferation of bacteria and, therefore, putrefaction, causing a mummification process. In addition, with the results obtained in this investigation and in other future ones, it will be possible to add scientific, anthropological, and forensic data on the analysis of the effects of quicklime in the stages of decomposition of human remain and in different deposition environments, to establish the time elapsed between death and the moment in which the body has been buried (exposed or not to quicklime) and contribute to criminal cases.

No / Extant literature contains a number of specific case studies on differential decomposition involving adipocere formation or desiccation, but few describe the co-occurrence of these features within a temperate climate. The case of a 65-year-old male, partially buried in a shallow grave for 7 months, is presented in which the soft tissues of the body were outwardly well preserved. The right leg was desiccated, some parts of the body were covered with adipocere (head, neck, right shoulder, upper torso and left leg) and other parts could be classified as in the early stages of decomposition. In this study the taphonomic variables resulting in differential decomposition with desiccation and adipocere formation are discussed.

A dietary reconstruction was performed in order to understand changing prehistoric subsistence patterns in the Central Andean geographical area of the Argentine Cuyo that includes the provinces of San Juan and Mendoza. Archaeologically, the Cuyo is also known as a boundary between Andean agriculturalists and the foragers of Patagonia. One hypothesis being tested is whether this area was one of the last South American cultural groups to convert to maize cultivation, probably around 2000 BP. The process of stable isotope analysis is used to reconstruct the diets of individuals, as it reveals the relative proportions of C3 and C4 plants and the contribution of aquatic resources to otherwise terrestrial diets, as well as variations in trophic level of the foods consumed. In this study the bones, teeth, hair, and flesh from 45 individuals were tested to address specifically total and protein diets, as well as seasonal variation and changes between childhood and adulthood. This process, when used in combination with previous analyses, such as midden or faunal analysis, allows researchers to evaluate the results of those previous studies, and thus compose a more thorough reconstruction of the lifestyles of a prehistoric culture. Information garnered from this study indicates that the times of dietary transition were variable, with seasonal patterns becoming more stable over long periods. Furthermore, some members of the study population demonstrate the existence of nutritional stress indicators, such as dental caries, that can be viewed in relation to the dietary shifts that may have been a cultural adaptation to the environment of the Cuyo. Overall, this study shows the early adoption of maize agriculture in central western Argentina and recommends future studies that analyze the relationships between agriculture, diet, and nutrition in the New World.

Cette étude retrace l’évolution de certains traitements réservés aux cadavres et aux restes humains en Égypte en se concentrant sur l’époque prédynastique et les six premières dynasties. Les cimetières contemporains de cette période de formation et d’affirmation des principaux éléments constitutifs de la civilisation pharaonique témoignent de la coexistence de pratiques funéraires associées à l’émergence de la momification artificielle et de pratiques mortuaires intervenant sur des corps partiellement ou totalement décomposés. L’objectif est de réévaluer par une approche archéothanatologique la documentation relative à ces deux catégories de traitements du corps, afin d’appréhender la diversité des pratiques de cette période. Cette étude vise donc à replacer le corps du défunt au centre de la discussion sur les pratiques mortuaires égyptiennes en prenant en compte deux ères chronologiques souvent considérées séparément. La relecture des publications archéologiques et de certaines archives de fouilles dans cette perspective a permis de proposer une sélection hétérogène de sépultures et de dépôts de restes humains provenant de 27 cimetières de la vallée égyptienne du Nil. Cette sélection d’inhumations offre une vision d’ensemble de la manière dont pouvaient être traités les défunts, ce qui permet de discuter de la continuité entre les pratiques prédynastiques et dynastiques et de confronter les données recueillies aux différentes interprétations possibles des gestes identifiés. / This study examines the evolution of practices pertaining to the treatment of human bodies and remains in Egypt from the Predynastic era through the first six dynasties. Burial grounds contemporaneous with the formation and affirmation of the principal constituents of the pharaonic civilization indicate the coexistence of funerary practices related to the emergence of artificial mummification, and mortuary practices involving partially or fully decomposed bodies. The purpose is to reevaluate, through the lens of archaeothanatology, the existing documentation regarding these two body treatment categories to better understand the diversity of practices over this period. The study aims to see the body of the deceased as the focal point of the discussion on Egyptian mortuary practices by taking into consideration two chronological eras often examined separately. Studying archaeological publications and archival documents of past excavations from this perspective provides a heterogeneous set of human sepultures and deposits found in 27 cemeteries throughout the Egyptian Nile valley. The cases chosen for the purpose of this study offer a comprehensive outlook into how the deceased were treated, which gives the grounds for discussing the continuity between predynastic and dynastic practices and for confronting the collected materials with diverse possible interpretations of these treatments.

Natural mummification occurs on every continent and in various environments. While the oldest preserved human being was discovered in the Swiss Alps, the high altitude mountains of Peru and Chile have also produced almost perfectly preserved human remains as well as a myriad of cultural artifacts. The bogs in Europe have also provided hundreds of preserved humans who appear to have fallen victim to ancient sacrificial ceremonies or capital punishment. The arid desert environments of Egypt and parts of Asia have also preserved the remains of individuals in their graves, buried in brightly colored clothing and given personal artifacts to be taken with them into the afterlife. Because the corpses and the cultural artifacts are so well preserved, natural mummies have yielded an enormous amount of previously unknown information. The purpose of this study is to provide a biocultural analysis of naturally mummified individuals and associated evidence to illustrate the lives of the people including information about status, health, diet, wealth, age, and sex of those individuals. To accomplish this objective, this study will focus on the environments responsible for preservation as well as numerous mummies and artifacts that have been found in them.

No / Despite an increasing literature on the decomposition of buried and exposed human remains it is important to recognise that specific microenviron-ments will either trigger, or delay the rate of decomposition. Recent casework in arid regions of the world has indicated a need for a more detailed understanding of the effects of burial over relatively short timescales. The decomposition of buried human remains in the coastal desert of Peru was investigated using pig cadavers (Sus scrofa) as body analogues. The project aims were to specifically examine the early phases of natural mummification and contrast the effects of direct burial in ground with burial in a tomb structure (i.e. with an air void). Temperature was logged at hourly intervals from both the surface, grave fill and core body throughout the experiment. In addition, air temperature and humidity were measured within the air void of the tomb. After two years all three pig graves were excavated, the temperature and humidity data downloaded and the pig carcasses dissected on site to evaluate condition. The results demonstrate that: (1) there were distinct differences in the nature/rate of decomposition according to burial mode; (2) after two years burial the carcasses had been subject to considerable desiccation of the outer tissues while remaining moist in the core; (3) the body had undergone putrefactive change and collapsed leading to slumping of soil within the grave fill following the curvature of the pig's back, although this was not evident from the surface; (4) there was a specific plume of body decomposition products that wicked both horizontally and also vertically from the head wounds in the sandy desert soil. These observations have widespread application for prospection techniques, investigation of clandestine burial, time since deposition and in understanding changes within the burial microenvironment under arid conditions.

Yes / Vast numbers of votive mummies were produced in Egypt during the Late Pharaonic, Ptolemaic, and Roman periods. Although millions remain in situ, many were removed and have ultimately entered museum collections around the world. There they have often languished as uncomfortable reminders of antiquarian practices with little information available to enhance their value as artefacts worthy of conservation or display. A multi-disciplinary research project, based at the University of Manchester, is currently redressing these issues. One recent aspect of this work has been the characterization of natural products employed in the mummification of votive bundles. Using gas chromatography–mass spectrometry and the well-established biomarker approach, analysis of 24 samples from 17 mummy bundles has demonstrated the presence of oils/fats, natural waxes, petroleum products, resinous exudates, and essential oils. These results confirm the range of organic materials employed in embalming and augment our understanding of the treatment of votives. In this first systematic initiative of its kind, initial findings point to possible trends in body treatment practices in relation to chronology, geography, and changes in ideology which will be investigated as the study progresses. Detailed knowledge of the substances used on individual bundles has also served to enhance their value as display items and aid in their conservation. / RCB is supported by a PhD studentship from the Art and Humanities Research Council (43019R00209).
