The Chehr Abad "Salt men" and the isotopic ecology of humans in ancient Iran

We have carried out isotopic analysis (δ(13)C and δ(15)N) on five salt-preserved bodies from the salt mine at Chehr Abad, Iran, dating from the 4th C. BC through to the 4th C. AD. In an attempt to identify the geographical origins of these people, we have analyzed over a hundred archeological bone samples from various archeological sites in Iran. From the faunal remains, we observe that the entire ecosystem appears to be enriched in (15)N, which we suggest is due to the semi-arid nature of the region. We have also observed a number of cattle remains from one site (Nargas Tepe) which have a significant C(4) component to their diet from the 4th millennium BC. By combining our data with those published by [Bocherens et al.: Environ Archaeol 5 (2000) 1-19; Bocherens et al.: J Arch Sci 33 (2006) 253-264], we suggest that two of the "mummies" may have come from the Tehran/Qazvin Plain region (i.e., relatively local to the salt mine), and a further two appear on isotopic grounds to have come from the northeast of Iran or the Turkmenistan steppes. The fifth (no. 4), the best preserved, appears to have come from further afield. Collectively, these mummies and their contexts augment our knowledge of social mobility and technical innovation in Iran during the Achaemenid period.     

The Dead Sea — an economic resource for 10 000 years

The archaeological and historical record of the Dead Sea as an economic resource is longer than that of any other hypersaline lake. Although it is completely devoid of life, except for a few bacteria and algae, the climatic and geological conditions in the Dead Sea basin have produced circumstances which made this lake important for the economy of the area. The salt which was produced by evaporation of the water, or by quarrying from the salt diapir of Mt. Sodom, on the Dead Sea coast, is referred to in the Bible and in the Talmud. It was harvested until the 1930's. Potash has been extracted from the brine, by solar processes, since 1931 and today the Dead Sea is a major source of potash and bromine. The asphalt, which is found in seepages along the shores and in large blocks, occasionally found floating on the lake, has been used by the inhabitants of the area for waterproofing baskets and for decorative purpose, since the Pre-ceramic Neolithic Period, 10 000 years ago. Later, the asphalt became a major export item to Egypt. During the Early Bronze age, 4000 years ago, it was used mostly to glue flint implements to wooden handles and in the Graeco-Roman period it was used as one of the components in the embalming of Egyptian mummies. The area around the Dead Sea was the only source of balsam, perhaps the most important incense and medication of the Ancient World. Remains of a 7th century B.C. perfume factory, were found in Ein Gedi. During later periods, until the Arab conquest in the 7th century A.D., the growing of balsam was an imperial monopoly. The area of the Dead Sea was famous, for over 2000 years, for its dates and sugar. The therapeutical and medicinal properties of Dead Sea water and the hypersaline hot springs on its shore, were famous throughout the Ancient World. For example, King Herod the Great, 2000 years ago, used to visit the area to cure his many diseases. This practice continues today, and the lakes has become a major center for treatment of psoriasis. There is pictorial, archaeological and historical evidence to support the Dead Sea's importance as a trade artery for over 2300 years.     

A note on the presence of blood groups A and B in pre-Columbian South America

The results of ABO typing in Chilean mummies, a review of published South American paleoserological studies and a systematic discrepancy of admixture estimates based on ABO and Gm genes support the hypothesis that Andean pre-Columbian populations possessed the A (and perhaps the B) gene in small frequencies.     

Tissue identification and histologic study of six lung specimens from Egyptian mummies

Twenty-eight specimens obtained either from organ bundles in the body cavities of intact mummies, from damaged mummies, or from isolated canopic jars were examined for tissue identification and histopathologic study. The methods of rehydration and fixation were optimized by application to 40 dehydrated modern samples before studies of mummified tissue were undertaken. The tissue of origin could be definitely identified in 24 of the 28 specimens. Even small fragments obtained from isolated canopic jars proved suitable for histologic study. Six lung specimens were selected for more detailed study. All six showed focal deposition of anthracotic pigment. Electron diffraction and electron microprobe analysis of one of the small, polarizable crystals associated with the anthracosis indicated a mineral content of silica, aluminum, and iron. Two specimens showed focal areas of calcification consistent with old mycobacterial disease. Other histopathologic findings included evidence of pulmonary edema, emphysema, and pneumonia.     

Instruments for transnasal brain removal during embalming by the ancient Egyptians

From the Mook—Collection in Munich 81 skulls and 7 complete heads of mummies found around Thebes and Abydos and dating from 1500–1000 BC were examined by fiberendoscope and operation microscope. Especially the nasal cavities and the ethmoidal perforations were studied through which the ancient moidal perforations were studied through which the ancient Egyptian embalmers removed the brain in the process of mummification. In many skulls these ethmoidal perforations had been nicely and meticulously prepared and we called in question whether this could be achieved merely by means of a metal hook as been described by Herodotus. We saw four different sites of the artificial foramina in the ethmoid. 22 perforations were symmetrically located in the ethmoid, 12 predominantly in the right ethmoid, 49 prediminantly in the left ethmoid and 5 perforations in the sphenoid. We present a new concept about the transnasal approach to the cranium, based on experiments in fresh cadavers in which we were able to remove the brain through the nostril by means of a simple rod of bamboo partially wrapped with moistened linen bandages. This technique of brain removal could during the process of mummification.     

Studies on protozoa in ancient remains - A Review

Paleoparasitological research has made important contributions to the understanding of parasite evolution and ecology. Although parasitic protozoa exhibit a worldwide distribution, recovering these organisms from an archaeological context is still exceptional and relies on the availability and distribution of evidence, the ecology of infectious diseases and adequate detection techniques. Here, we present a review of the findings related to protozoa in ancient remains, with an emphasis on their geographical distribution in the past and the methodologies used for their retrieval. The development of more sensitive detection methods has increased the number of identified parasitic species, promising interesting insights from research in the future.     

Blood-group determination in ancient Peruvian material

The problem of blood-grouping Peruvian mummies involves the theories on the origin of ABO polymorphism and current hypotheses concerning the peopling of the New World.Some attempts to perform these determinations were made by several research-workers. Owing to different results, especially for what concerns the presence or absence of A and B antigens, some of the results seemed neither reproductive nor reliable and suggested the hypothesis for the presence of contaminating substances.Since a purification method suitable for mummified material had been set-up in our laboratory and applied with successful results to Egyptian specimens, we thought it worthwhile to try its application to ancient Peruvian material.A sample of cancellous bone was ground-up, washed with pure melted phenol and with ethanol and extracted by 5% E.D.T.A. The extract was filtered through Sephadex G 25 columns and tested with H.I. reaction using anti-A and anti-B human sera and anti-H lectin prepared, purified and controlled for its specificity in our Laboratory.Grouping with this technique 33 Inca or pre-Inca Peruvian specimens, mostly coming from Ancon and Cuzco, 28 group O were found, while 5 samples were not diagnosed.     

The pubic scars of gestation and parturition in a group of pre-Columbian and colonial Peruvian mummies

The pubic scars of pregnancy and parturition as reported in the anthropological literature are a variant of the recognized clinical entity, osteitis pubis. The os pubis from 86 pre-Columbian and colonial Peruvian mummies were examined for this entity. Osteitis pubis was found in 13 pre-Columbian females (72.3%) and 19 colonial Indians (57.6%). Four of the colonial women were buried with newborn children and one had a four-month-old fetus in utero. This type of study has application in paleopathology and forensic medicine to show possible frequency of pregnancy in a population, but must be refined and quantitated to achieve any more than this. This study is of further interest as it demonstrates that racial groups have apparently a wide difference in frequency of this particular lesion of the pubic symphysis, a matter for further investigation.     

Attempts to revive Mycobacterium tuberculosis from 300-year-old human mummies

Environmental persistence of Mycobacterium tuberculosis is subject to speculation. However, the reality that infected postmortem tissues can be a danger to pathologists and embalmers has worrisome implications. A few experimental studies have demonstrated the organism's ability to withstand exposure to embalming fluid and formalin. Recently, a failure was reported in an attempt to resuscitate an original isolate of Robert Koch to determine the lifetime of the tubercle bacillus. The present study also considers a historical approach to determine persistence under favorable environmental conditions. It asks whether acid-fast forms observed in tissues of 300-year-old Hungarian mummies can be resuscitated. Finding organisms before the advent of antibiotics and pasteurization may yield valuable genetic information. Using various media modifications, as well as guinea pig inoculation, an attempt was made to culture these tissues for M. tuberculosis. In addition, a resuscitation-promoting factor, known to increase colony counts in high G+C bacteria, was applied to the cultures. Although an occasional PCR-positive sample was detected, no colonies of M. tuberculosis were obtained. Our results may indicate that the life span of the tubercle bacillus is less than a few hundred years, even though in the short run it can survive harsh chemical treatment.
