Stable carbon- and nitrogen-isotope ratios and electron spin resonance (ESR) g-values of charred bones: changes with heating and a critical evaluation of the utility of g-values for reconstructing thermal history and original isotope ratios

Changes in the stable carbon and nitrogen isotope ratios of modern bone samples heated to a variety of times and temperatures were used to determine the effect of heating on isotope ratios and the retention of organic matter in charred bones. For organic extracts produced by slow demineralization in weak acid, δ¹³C values were unchanged, while δ¹⁵N values increased by up to 5‰ and were primarily determined by heating temperature. Changes in the electron spin resonance (ESR) g-value of whole bone and organic extracts were also measured. For organic extracts from charred bones, the g-value was well-correlated with δ¹⁵N and temperature, suggesting that g-values could be used to estimate the charring temperature and original δ¹⁵N values of charred bones. Thus, g-values from demineralized extracts could be very useful in forensic investigations where it would important to reconstruct the thermal history of burned bones. Isotope ratios and g-values of demineralized extracts from four prehistoric components at three sites that produced cremated human bone were used to test whether the same approach can be applied to archaeological materials. While carbon isotope ratios of the prehistoric samples were similar to those of uncharred specimens, nitrogen isotope ratios were increased and the g-value corrections for nitrogen isotope ratios were not effective.     

Ashes to ashes. Fuelwood selection in Roman cremation rituals in northern Gaul

To analyse fuelwood collection strategies in Roman funerary rituals in northern Gaul, a large number of charcoal fragments from Roman cremation graves has been identified. The wide variety of taxa found suggests that no particular taxa have been avoided. Also no significant differences have been found between the charcoal assemblages of different types of graves and between graves belonging to different types of settlements. On the other hand, comparison with the charcoal assemblages from Roman refuse deposits, reflecting domestic fuel use, shows an overrepresentation of Quercus sp., Alnus sp. and Fagus sylvatica, and a much lower taxonomic variety in the cremation graves. This is believed to be the consequence of functional rather than ritually or symbolically oriented fuelwood selection strategies.     

北京地区的火葬墓及相关问题研究

北京地区发现的火葬墓属于辽、金、元、明、清等时期,这些火葬墓在构筑材料、形制、葬具等方面均不尽相同,墓主有汉人,也有契丹、女真、蒙古、满族等少数民族。辽金元时期北京地区火葬墓较为盛行,明朝时期有所减少,至清朝时又有所增加。火葬习俗的变化与不同民族的丧葬习俗、宗教信仰和统治者对火葬的态度及政策有关。     

Material evidence for the use of Attic white-ground lekythoi ceramics in cremation burials

White-ground lekythoi ceramics offer important evidence for funeral practices in Ancient Greece (5th century BC). The images painted-on these oil containers provide the best visual narrative for the events surrounding death, including indications that the vessels themselves were used as part of the funerary rites. However, until now, their specific function and treatment within the funeral ceremony was not well understood. We present here material evidence that the vessels were ritually burned, together with the body of the deceased, during cremation, as evidenced by a diffuse purplish-red discolouration found on many white-ground lekythoi. Through EPMA and μXAS studies, we show that: (1) this characteristic purplish-red discolouration is due to the presence of metallic copper nano-particles embedded in a glassy layer; (2) this metal-glass matrix formed as the result of a high temperature reaction between painted-on Cu-based pigments (e.g., Egyptian blue) and the white-ground ceramic slip; and (3) the reaction occurred under a reducing environment. Given the mortuary context for these vessels, we propose the reduction firing to which the vessels were exposed was that associated with the cremation of the body. The observation of discontinuous formation of the purplish-red discolouration along adjoining fragments supports the hypothesis that the vessels were broken prior to being burned. The majority of lekythoi in museum collections lack information on their original archaeological context, and our data suggest the presence of this purplish-red discolouration may serve as a visual marker for cremation. As such, it is expected our findings will provide a new basis for interpreting how this important class of ceramic, and associated iconographic imagery, relates to Athenian funerary practices and the ancient Greek notion of death.     

Implications of heat-induced changes in bone on the interpretation of funerary behaviour and practice

Bones submitted to heat experience structural and chromatic modifications. In particular, heat-induced bone warping and thumbnail fractures have been linked to the burning of fleshed and green bones – where the soft tissues have been removed from the bones soon after death – in contrast to dry bones. Those have been suggested as indicators of the state of the individual before being burned thus allowing inferences about the funerary behaviour of archaeological populations. A large sample of 61 skeletons submitted to cremation has been examined for the presence of both of these heat-induced features. Although uncommon, bone warping and thumbnail fractures were present in some of the skeletons demonstrating that its presence is not restricted to the burning of non-dried bones as generally believed. Rather than being an indicator of the presence of bones with soft tissues, bone warping seems to be more of an indicator of the preservation of collagen–apatite links which can be maintained on dry bones with low collagen deterioration. In addition, our results also do not confirm thumbnail fractures as an exclusive sign of the burning of bones with soft tissues. As a result, these heat-induced changes should be used with caution when trying to infer about the pre-burning state of an individual.     

Hydatidosis of a Pregnant Woman of the 3rd Century bc,Greece

Analyses of cremains of three individuals from a 3rd‐century‐bc hydria revealed a calcified hydatid cyst among commingled bones of a man, woman and fetus. The free cyst likely belonged to the pregnant woman who may have died of hydatidosis, a disease known in Greece since the 5th century bc . Hydatid cyst finds are rare in the literature. This is the first cyst found with cremains and in Greece. Copyright © 2015 John Wiley & Sons, Ltd.     

The case of the disorderly graves: Contemporary deathscapes in Guangzhou

The first part of this paper describes three agendas that are shaping contemporary deathscapes in Guangzhou: the modernist planning agenda; the market economy; and the Chinese Communist Party ideology and resistance to it. The second part interprets three significant aspects of these deathscapes: first, the survival of an old tradition ( fengshui ); second, the appearance of a new spatial practice (storage of ashes in landscaped cemeteries); and, third, the contemporary reinterpretation of the grave as a symbol of individual rather than lineage status. Finally, these deathscapes are analysed as 'deathspace', a symbolic system that represents a stage in an ongoing process of conflict and compromise involving the traditional and the modern, the personal and the political, and the sacred and the secular.     

Identification of the first reported Lapita cremation in the Pacific Islands using archaeological,forensic and contemporary burning evidence

Burnt human remains excavated from a scoop feature from a cemetery at Teouma, Vanuatu in the western Pacific (∼2850 BP) were examined to assess the nature of the deposit. Possible scenarios explaining the reason the bone was burnt and interred were assessed using osteological signatures taken from archaeological, experimental, and forensic studies. The methodology of the study included recording color change, types of bone distortion, and element representation in conjunction with archaeological evidence. The burnt and fragmented human bone (n = 430, fragments weighing 620 g) represents a single adult individual. Macroscopic evidence from the bone indicates the body had been fleshed or fresh at the time of burning and element representation follows a similar pattern to other burials excavated from the site. Excluding burning, there was no evidence of human modification to the bone such as cut marks, percussion pits or peri mortem trauma suggestive of cannibalism. The archaeological evidence from the site indicates that the body had not been burnt in the place the remains were subsequently discovered. The combined macroscopic and archaeological evidence strongly suggests that the human bone was burnt as a result of a deliberate cremation of an individual. If a conclusion of deliberate cremation is accepted, this research represents the first case of a Lapita period cremation and demonstrates how a combination of methods can explain the nature of an archaeological deposit of burnt human bone when the cause is not otherwise apparent.
