Investigation of Organic Materials From the ‘Royal’ Burials of Xiongnu (Noin‐Ula,Mongolia) by Srxrf and XAFS Methods

The burials of famous Xiongnu people are a unique source of information about Xiongnu culture, due to the variety of organic findings. SRXRF analysis of hair, clay, bones, teeth and woollen cloth was carried out. An anomalously high copper content was observed in all hair samples, whereas the levels of copper in bone and clay were low. To define the hair morphology and the elemental distribution in the hair cross‐section, high‐resolution X‐ray computed tomography (HRXCT) and energy‐dispersive spectroscopy (EDS) with scanning electron microscopy (SEM) were used. The X‐ray absorption fine‐structure method (XAFS) was applied to determine the local copper environment. The majority of the copper species in the hair and enamel samples are present as Cu²⁺ cations in a distorted octahedral (4 + 2) coordination, surrounded by light ligands (oxygen/nitrogen). A similar distorted octahedral coordination is typical for both inorganic mixed oxide/hydroxide Cu nanosystems and metal–organic Cu complexes (with oxygen/nitrogen).     

Hydrogen isotope systematics of hair: archeological and forensic applications

The hydrogen isotope systematics of hair have been explored and several applications demonstrate the type of information that can be recovered from archeological and forensic hair samples. Experiment with modern hair demonstrate that sources of protein-based hydrogen in keratin are food and water. On the basis of a deuterium-enriched drinking study, it was found that 31% of hydrogen in human hair is derived from ingested water. At least 9% of total hydrogen in human hair is isotopically exchangeable with water or water vapor at 25 °C. Nearly complete exchange occurs in a matter of hours. The δD value of body water is approximately 17±10‰ (n=7) more negative than human hair, although there is much scatter in data for modern hair, which is clearly related to variability of the isotopic composition of ingested food and water. Archeological hair samples were analyzed from (i) a 370 year old Incan mummy sacrificed at 5300 m altitude in Argentina (Geoarchaeology 14 (1999) 27) and (ii) from a Woolly Mammoth from Siberia. High spatial resolution data along the length of hair from the mummy indicate seasonal variations in carbon, nitrogen and hydrogen isotope ratios. No hydrogen isotope anomalies are seen in the youngest hair at the base of the scalp, indicating that the individual probably lived at 1600 m, and spent less than a week at high altitudes before death. The mammoth also preserves a seasonal signal, suggesting hair growth rates of 33 cm/year, faster than human hair, but slower than horse tail hair. The limited isotopic range across seasons for the mammoth is consistent with a north-south migration on the order of 1000 km.     

CHANGES IN THE METAL CONTENT OF HUMAN HAIR DURING DIAGENESIS FROM 500 YEARS,EXPOSURE TO GLACIAL AND AQUEOUS ENVIRONMENTS

Scanning electron microscopy, inductively coupled plasma mass spectroscopy and time‐of‐flight secondary ion mass spectrometry have been used to examine the extent and possible mechanisms by which the metal content of human hair is altered by exposure to aqueous environments. The results, using both modern hair and samples from 500‐year‐old hair associated with glacier‐entombed remains, show that the metal content has been altered sufficiently so that the interpretation of the metal signature in terms of diet or disease is problematic. While endogenous information is difficult to glean from these data, interesting observations have been made of possible early stages of mineral authigenic deposition. The chemistry of the outer hair surface was found to be consistent with deposition of Fe and Al silicates, as well as other mineral phases. The ancient hair was analysed at the root region and included a comparison of the internal versus external composition to assist in identifying the diagenetic processes.     

Seasonality and paleodiet in the Chiribaya polity of southern Peru

In the Andes, the complex Chiribaya polity, or señorío, was composed of economically specialized groups. Previous carbon and nitrogen isotope analyses of archaeological human bone from Chiribaya-affiliated sites have effectively demonstrated socioeconomic specialization and variability in paleodiet among different Chiribaya-affiliated sites. The present study complements earlier paleodietary analyses of Chiribaya populations by supplementing them with carbon and nitrogen isotope analyses of archaeological human hair from the two Chiribaya-affiliated sites of Chiribaya Alta and El Yaral. These new data demonstrate that seasonal variability in the consumption of marine products and C₄ plants such as maize was quite high for some individuals buried at Chiribaya-affiliated sites. In addition to elucidating the complex patterns of Chiribaya seasonality, this study contributes to the growing body of knowledge of archaeological analyses of human hair for paleodiet.     

Isotopic Determination of Seasonality in Diet and Death from Nubian Mummy Hair

Sections of human hair from naturally desiccated Sudanese Nubian mummies representing X-Group (AD 350-550) and Christian (AD 550-1300) periods in the Wadi Halfa area have been analysed for their isotope ratios. Because the carbon in hair represents food intake over the growth period of this tissue, analysis comparing segments taken next to the scalp with those further along the shaft can indicate diet just prior to death as well as any recent shift in food consumption. Modern populations in this area practise seasonal crop scheduling which involves the cultivation of C₃ plants (wheat, barley and most fruits and vegetables) in the winter and the hardier C₄ plants (sorghum and millet) in the summer. Shifting isotopic values along the length of hair strands of the ancient inhabitants of this area demonstrate that this practice has its roots at least as far back as the Initial Phase of Intensive Agriculture. The most common season of death appears to have been summer, the time of greatest climatic, nutritional and physiological stress for both ancient and modern inhabitants.     

Ancient Egyptian hair gel: new insight into ancient Egyptian mummification procedures through chemical analysis

Artificial mummification in ancient Egypt involved the application of chemicals to the body mostly for the purpose of preservation; others were applied for ritual aspects. Unguents were used also in everyday toilette. Here we report a type of material which was applied specifically to the hair, a fatty material used as a ‘hair gel’. Personal appearance was important to the ancient Egyptians so much so that in cases where the hair was styled the embalming process was adapted to preserve the hair style. This further ensured that the deceased’s individuality was retained in death, as it had been in life, and emphasises the importance of the hair in ancient Egyptian society.     

Seasonal fluctuations in diet and death during the late horizon: a stable isotopic analysis of hair and nail from the central coast of Peru

The goal of the isotopic analysis of hair and nail from Puruchuco-Huaquerones is to reconstruct short term paleodiet using the stable isotopes of carbon and nitrogen in one centimetre increments of hair and two discrete points (distal and proximal) on the nail. This sampling method allows for the reconstruction of diet on a monthly basis (hair) and also diet at two periods (nail): four months and two weeks antemortem. The analysis of these two tissues demonstrates that diet varied from month to month and that food was not stored in any significant quantity. The patterning of the isotope data appears to be closely tied to the agricultural cycle, although a vertical economy cannot be rejected as an alternative explanation. Isotope data for both short (e.g., hair and nail) and long term diet (e.g., bone) are similar; this is interpreted as evidence for the continuity of the settlement in this area. There are no significant differences in the season of death between males or females or between the winter and summer months. The slightly higher mortality rate in the summer may be due to crop failure and subsequent food shortages.     

Hair in the Disraeli Papers: A Victorian Harvest

The Hughenden Collection of Disraeli Papers at the Bodleian Library in Oxford comprises over 50,000 items relating to the life and work of Benjamin Disraeli and his family. This article tracks hair through the Hughenden Collection in order to explore the collecting habits of Mary Anne Disraeli. It argues that reading Mary Anne Disraeli's story through hair – both hair as object, held in an archive and hair as represented in archival text – reveals aspects of that story occluded by reading only those archival texts with self-evident documentary value. It thus makes the case for a holistic reading of the Disraeli archive, and Victorian collections of personal papers more generally, by taking Mary Anne Disraeli as its central case study. In so doing it also illuminates her story, and points to the necessity of reading the stories of forgotten women through archival silences and absences. Section I reviews recent scholarship on hair in nineteenth-century Britain in order to contextualize Mary Anne Disraeli's case. Section II anatomizes the Hughenden hair collection in order to illuminate Mary Anne's history, her impulses as a collector, and the extent to which her activities complicate scholarly narratives about the sentimental commodification of Victorian hair. Section III gestures towards recent work on the archive and material culture to tease out the consequences of her example for our reading of the archive and our understanding of the texture of Victorian ‘thing culture’ more generally.     

Was He Murdered or Was He Not?—Part II: Multi‐Elemental Analyses of Hair and Bone Samples from Tycho Brahe and Histopathology of His Bones

Hair and bone samples procured from the remains of Tycho Brahe were analysed by several analytical techniques. In segmented hair samples, concentrations of Fe, As, Ag and Au at the tips exceeded values for the contemporary population; however, they decreased towards the hair bulbs, similarly to Hg, indicating that recent exposure that was discontinued ~2 months prior to Brahe's death. Several other elements did not follow this pattern. Analyses of bones revealed signs of long‐term exposure to Au, while many other elements were within expected ranges. Histopathological examination of bone sections yielded no signs of severe bone metabolic disorders.     

Nicotine in the hair of mummies from San Pedro de Atacama (Northern Chile)

The consumption of plant-derived hallucinogenic substances through smoking and snuffing is a long-standing tradition in the south-central Andes. Chemical and archaeobotanical evidence point to the consumption of nicotine and tryptamine alkaloids in Northwestern Argentina and of tryptamine alkaloids in San Pedro de Atacama (SPA), in prehispanic times. In this paper, results are reported of gas chromatography–mass spectrometry (GC/MS) analyses aimed at identifying nicotine and tryptamine alkaloids in the hair of mummies from different cultural periods of SPA. Fifty-six samples were examined. While tryptamines were not found in any of the samples, nicotine was found in 35 samples, assigned to the Late Formative (1 of 1 sample from this period), Late Formative or Middle (1 of 2 samples from either of these periods), Middle (4 of 6 samples from this period) and Late Intermediate periods (8 of 12 samples from this period), or without assignment to period due to lack of contextual information (21 of 35 samples unassigned to a period). These results show a continuous consumption of nicotine from the Late Formative to the Late Intermediate periods of SPA (ca. 100 B.C.–1450 A.D.). No associations were found between presence of nicotine in the hair of mummies and presence of snuffing trays or of other snuffing paraphernalia in the corresponding tomb; furthermore, neither the diversity of the funerary context, measured in terms of the number of types of objects, nor the presence of gemstone necklaces differed between tombs with mummies with or without nicotine in their hair. Overall, these results suggest that consumption of nicotine was performed by members of the society at large, irrespective of their social and wealth status.     

Isotopic Comparison of Hair,Nail and Bone: Modern Analyses

This paper presents a comprison of the isotopic values of eight pairings of hair keratin and bone collagen and 12 pairings of hair keratin and nail keratin taken from living humans resident in the U.K., with the aim of examining whether modern human isotopic data can be directly compared to archaeological isotopic data.Results showed that bone collagen was enriched relative to hair keratin from the same individual by +1·4‰ in δ¹³C and +0·86‰ in δ¹⁵N, with some small degree of variability. Isotopic comparison of hair keratin and nail keratin from the same individual showed that there is no significant difference between hair and nail keratin in δ¹³C, but that nail keratin is on average +0·65‰ more enriched in δ¹⁵N than hair.Differences in amino acid composition between hair keratin and bone collagen may account for the carbon isotopic differences between the two proteins, and there is no significant overall carbon isotopic difference between hair and nail. However there are significant isotopic differences for nitrogen in the two pairings, that differences in amino acid composition and turnover times cannot explain. We suggest that these results indicate that constancy of isotopic values between tissues, even for similar proteins, cannot be taken for granted.     

Ultramicroscopic investigation of the preservation status of hair collected from a full‐term,intrauterine baby mummy of the Joseon Dynasty,Korea

Our previous studies on the ultramicroscopic structure of mummy hair from Joseon Dynasty (1392–1910) tombs sealed with a lime‐soil mixture barrier (LSMB) have provided initial, basic information on their preservation status. Numerous additional cases of various conditions are required in order to provide data sufficient for establishing Korean mummy preservation patterns on a firm basis, however, and so we performed electron microscopic studies on hair taken from a full‐term, intrauterine baby mummy found in Paju, Korea. The baby mummy was found within the uterus of a 16th‐century mummified woman aged 20–30 years old. Since the labour and delivery stage for this case was 2, and the uterus was found to be ruptured, the cause of death of both the mother and the baby was likely to have been hypovolemic shock occurring during labour. In scanning electron microscopic (SEM) and transmission electron microscopic (TEM) studies, we found that the surface of the hair of the baby mummy was coated with crystalline substances, mainly on the side facing the vaginal orifice. We also observed well‐preserved cuticle, cortex and medullar layers, completely preserved cuticle‐layer scales, as well as macrofibrils and melanin granules evenly spread within the cuticle and cortex layers. Because studies on infant or subadult mummies are very few, and since they have focused mainly on the palaeopathological aspects of those mummies, the preservation pattern of the hair of a full‐term baby mummy could contribute significantly to our knowledge of mummies from around the world.

Archaeological human hair in a burial context: Microscopical evaluation of samples from Iași,Romania (18th–19th centuries)

Owing to its resistance to degradation, hair is an important bio-sample with unique properties used to study post mortem decompositional changes. The present paper is a microscopical approach to preserved human scalp hair discovered at the 18th–19th-century archaeological site of Iași, Romania. The hair fibre alterations were assessed using optical microscopy, scanning electron microscopy, image analysis and hair histological scores. External alterations showed a statistically significant heterogeneous degradation. Image analysis results of the internal degradation of hairs were correlated to external lesions. The results consider the implication of intrinsic biological factors in the post mortem degradation of human hair preserved in graves with comparable environmental conditions.     

Structural stability of hair over three thousand years

Ten hair samples of Copts from the 8th–10th century AD obtained during the 1963–1964 excavation campaign in the district of Sayala, and 11 hair samples of Egyptian mummies dated to the 18th–25th dynasty were examined for their structural properties compared with recent hair samples. Structural comparison was performed using X-ray diffraction and infra-red spectroscopy. Using the attenuated total reflection technique, which allows multiple reflection infra-red spectroscopy on native hair, we were able to reveal the structural integrity of the ancient hair samples. X-ray diffraction studies using Cr-alpha radiation confirmed the infra-red results. Signs of dehydration could be observed but no conformational changes, indicating the structural stability of hair protein over thousands of years.     

Hair surface and mechanical properties of Copt mummies from Antinopolis

In the late nineteenth century, excavations were conducted in the necropolis of the site of Antinopolis, a city founded in 130 CE. Over sixty Copt mummies, out of the thousands of graves excavated, were brought to France in the early twentieth century. Unlike mummies of the Pharaonic era, no specific study has been conducted on the mummies of the Christian era. To identify these techniques of mummification and their state of preservation, the Louvre museum has conducted a multidisciplinary study on thirty-nine mummies located throughout France.In this work, we studied the surface topography and the mechanical properties of the hair from eleven mummies.To qualify the hair wear, 3D topography of their surface has been measured with an interferometer of vertical resolution 2 nm and an analysed surface of 20 × 84 μm. The results show that, for most of the hair samples, the cuticle has completely disappeared and the cortex appears very porous. However, for a few of the hair samples, the scales are perfectly regular like those of healthy hair, which is probably due to the mummification techniques used.The mechanical properties of the hair were determined using a three-point bending mechanical test.The results show that the mechanical hair properties are not correlated with the surface morphology of the cuticle.     

Studies on amerindian dogs, 1: Carbon isotopes in relation to maize in the diet of domestic dogs from early Peru and Ecuador

Work initiated purely as a dating project in support of a craniometric and morphological investigation of domestic dogs from early Peru has proved to have much wider implications. The stable carbon isotoperatios (¹³C/¹²C) of hair samples from ten dogs show that maize formed a significant part of their diet. Radiocarbon dates for these remains have confirmed that they belong to the period well after the cultivation of maize was first established. Stable carbon isotope measurements can thus be used to test for the presence of maize as a dietary constituent at earlier sites even where there is otherwise only indirect evidence for its cultivation. Collagen from animal or human bone is a suitable alternative to hair for this purpose and the method has been successfully applied to collagen dating to c. 3000 BC from the Valdivia culture site of Real Alto, Ecuador, as well as to a series of early Peruvian dogs.     

胡人发型:中古“剪头胡雏”艺术形象试解

古人发型是文化界长期关注的一个重要现象。发型不仅是时代的特征与时尚的符号,也是各个族群的辨识标志。从北朝到隋唐的中古社会,"剪头胡雏"的文物图像屡屡出现,一般来说,此类胡人形象是剪发而不是束发,在当时以"高髻为尚"的社会习俗中,"剪头胡雏"发型是有着"阶级感"的存在,是有关底层胡人的直观艺术产物。也说明当时入华胡人还没有彻底"汉化",仍然保留着本族群的发型特征。该发式是胡人与汉人的区别,也是其身份归属的象征。     

SKIN, AND WOOL-TEXTILE REMAINS FROM HALLSTATT, AUSTRIA

Summary. A study was made of wool cloth remains comprising 56 yarns and of 33 samples of haired animal skin from the Kilbwerk salt-mine site at Hallstatt, Austria dated 6th to 8th century BC. Most of the wool in the cloth was primitive hairy-medium or generalised-medium type and over half the samples had natural coloration, the predominant colour being grey. One yarn was of medium wool type and four were of semi-fine fleece type, neither of these having been previously reported before the Roman period. The skins were much hairier, only one-third having fleece types found in the cloth, and only two of these were of the finer generalised medium variety. Most of the skins with the coarsest hair were probably from goats, and those with less coarse hair from true hairy sheep, a fleece type that is thought to have developed during the Iron Age. The staining reaction of the skin indicated rawhide or oil tanning. The presence of inactive hair follicles within the skin showed that over half had ceased to live during the autumn-winter period.     

Technologies of Appearance: Hair Behaviour in Early Medieval Europe

Personal appearance in general—and the grooming of hair in particular—has long held a position of interest in historical, art-historical, and literary scholarship. The same cannot be said of archaeology, and the material aspects of personal grooming in the construction and communication of identity have not been fully synthesized. As a result, little attempt has been made to understand the social role of hair in less well documented societies, such as those of early medieval northern and western Europe. This paper considers archaeological, iconographic and documentary evidence for the significance of, and physical engagement with hair in early medieval northern and western Europe, and offers a model for the interpretation of grooming as a social phenomenon. It is argued that grooming was a socially meaningful practice, and that it played a key role in the construction of early medieval identities, as well as in the maintenance and manipulation of boundaries and distinctions between individuals and groups.
