Roman Period fetal skeletons from the East Cemetery (Kellis 2) of Kellis,Egypt

Much can be learned about the religious ideology and mortuary patterns as well as the demographic and health profiles of a population from archaeological human fetal skeletons. Fetal skeletons are rare, however, largely due to poor preservation and recovery, misidentification, or non‐inclusion in general burial populations. We present an analysis of 82 fetal/perinatal skeletons recovered from Kellis 2, a Roman Period cemetery dated to the third and fourth centuries AD, located in the Dakhleh Oasis, Egypt. Most of the fetal remains were individually wrapped in linen and all were buried among the general cemetery population in a supine, east–west orientation with the head facing to the west. Gestational age estimates are calculated from diaphysis lengths using published regression and Bayesian methods. The overall similarity between the fetal age distributions calculated from the regression and Bayesian methods suggests that the correlation between diaphysis length and gestational age is typically strong enough to avoid the ‘regression’ problem of having the age structure of reference samples adversely affecting the age distribution of target samples. The inherent bias of the regression methods, however, is primarily reflected in the gestational age categories between 36 and 42 weeks corresponding with the expected increase in growth variation during the late third trimester. The results suggest that the fetal age distribution at Kellis 2 does not differ from the natural expected mortality distribution. Therefore, practices such as infanticide can be ruled out as having a significant effect on the observed mortality distribution. Moreover, the Kellis 2 sample is well represented in each gestational age category, suggesting that all premature stillbirths and neonatal deaths received similar burial rites. The age distribution of the Kellis 2 fetal remains suggests that emerging Christian concepts, such as the ‘soul’ and the ‘afterlife’, were being applied to everyone including fetuses of all gestational ages.

Confocal laser scanning microscopy: a flexible tool for simultaneous polarization and three-dimensional fluorescence imaging of archaeological compact bone

Wide-field polarized light and epifluorescence microscopy have been used to enhance analysis of archaeological bone tissue, providing information on bone formation, modeling, pathology, preservation, age estimation, and biomechanics. Though valuable, these techniques are limited by their inability to remove out-of-focus light and view multiple levels of a sample, restricting our understanding of the three-dimensional (3-D) microarchitecture of compact bone. Modern technological advances, such as microscopic computerized tomography, allow increasing resolution in 3-D bone imaging, but do not allow fluorescence labeling or polarized-light analysis. Confocal laser scanning microscopy (CLSM) is a valuable tool for 3-D histology. However, its application to the study of compact bone is lacking, especially in archaeological and forensic sciences. The current study investigated CLSM as a tool for fluorescence and polarized-light microscopy of archaeological compact bone in order to demonstrate its advantages. Standard techniques and CLSM are compared in their suitability for imaging well preserved archaeological bones from the Dakhleh Oasis, Egypt. CLSM's high resolution, multi-channel, two- and three-dimensional capabilities augment the flexibility and creativity of compact bone imaging and have the potential to increase the accuracy of quantitative medical and anthropological histomorphometric techniques. CLSM is specifically suggested as a useful tool for the investigation of ancient bone fluorescence caused by the presence of tetracycline and/or other fluorochromes.     

Evidence of amputation as medical treatment in ancient Egypt

The use of surgical techniques in ancient Egyptian medicine has only been suggested indirectly through ancient medical texts and iconography, and there is no evidence of amputation as a means of therapeutic medical treatment. This paper presents four cases of amputation from the archaeological site of Dayr al‐Barshā, Egypt. Two of the cases (dated to the First Intermediate and Middle Kingdom periods, respectively) are from individuals that display bilateral amputations of the feet, one through the metatarso‐phalangeal joints, the other a transmetatarsal amputation. The exact reason for the amputation, perhaps from trauma or disease, is unknown. The particular healing patterns of the distal ends of the amputations suggest these individuals used foot binding or prosthetic devices. Another case represents a healed amputation of the left ulna near the elbow, dated to the Old Kingdom. The final case represents a perimortem amputation of the distal end of the right humerus. The exact date of this individual is unknown, but most likely pertains to the Old Kingdom or First Intermediate period. This individual seems to have suffered a traumatic incident shortly before death, sustaining many fractures, including a butterfly fracture on the right humerus. Several cut marks were identified on top of the butterfly fracture, indicating amputation of the arm at this point. All four cases support the hypothesis that the ancient Egyptians did use amputation as a therapeutic medical treatment for particular diseases or trauma. Copyright © 2009 John Wiley & Sons, Ltd.
