Interpretation of bulk nitrogen and carbon isotopes in archaeological foodcrusts on potsherds.

RATIONALE: Foodcrust, the charred deposit adhering to the surface of containers, is a possible source of information on the function of ancient vessels and the subsistence of prehistoric humans. While the carbon isotope ratios in those materials are useful in detecting the usage of C4 plants, the reliability of nitrogen isotopic signatures has not been fully investigated. METHODS: The validity of bulk nitrogen isotope ratios has previously been investigated in coastal or riverine environments, where multiple resources from terrestrial and aquatic ecosystems were available, but not in terrestrial settings which provide a simpler mixing of terrestrial animals and plants. Hence, we conducted an exhaustive study on charred deposits on potsherds at two inland archaeological sites belonging to prehistoric Jomon hunter-gathers in central Japan, focusing on δ15 N values and atomic N/C ratios determined using an isotope ratio mass spectrometer and an elemental analyzer, respectively. RESULTS: For both sites, the δ15 N values showed significant correlations with the N/C ratios among samples from the inner surface, suggesting that these have recorded animal contribution. Furthermore, previous studies of Neolithic pottery from North Europe and Far East Russia bearing strong marine signatures had shown reasonably higher δ15 N values and N/C ratios in comparison with our data from terrestrial settings. On the other hand, some charred materials probably originating from plant starch showed lower values with both parameters. Samples from the outer surface produced less meaningful isotopic and elemental ratios altered by a thermal effect and/or contamination from soot. CONCLUSIONS: When the samples of foodcrusts were selected carefully from the inner surface, bulk nitrogen isotopes and N/C ratios reflect the composition of what was cooked or processed in containers. This will provide useful information for understanding the human adaptation from the Late Pleistocene to the Holocene in conjunction with residual lipid analyses.

Beginning of viniculture in France.

Chemical analyses of ancient organic compounds absorbed into the pottery fabrics of imported Etruscan amphoras (ca. 500-475 B.C.) and into a limestone pressing platform (ca. 425-400 B.C.) at the ancient coastal port site of Lattara in southern France provide the earliest biomolecular archaeological evidence for grape wine and viniculture from this country, which is crucial to the later history of wine in Europe and the rest of the world. The data support the hypothesis that export of wine by ship from Etruria in central Italy to southern Mediterranean France fueled an ever-growing market and interest in wine there, which, in turn, as evidenced by the winepress, led to transplantation of the Eurasian grapevine and the beginning of a Celtic industry in France. Herbal and pine resin additives to the Etruscan wine point to the medicinal role of wine in antiquity, as well as a means of preserving it during marine transport.

Ritual Black Drink consumption at Cahokia.

Chemical analyses of organic residues in fragments of pottery from the large site of Cahokia and surrounding smaller sites in Illinois reveal theobromine, caffeine, and ursolic acid, biomarkers for species of Ilex (holly) used to prepare the ritually important Black Drink. As recorded during the historic period, men consumed Black Drink in portions of the American Southeast for ritual purification. This first demonstrated discovery of biomarkers for Ilex occurs in beaker vessels dating between A.D. 1050 and 1250 from Cahokia, located far north of the known range of the holly species used to prepare Black Drink during historic times. The association of Ilex and beaker vessels indicates a sustained ritual consumption of a caffeine-laced drink made from the leaves of plants grown in the southern United States.

Early pottery at 20,000 years ago in Xianrendong Cave, China.

The invention of pottery introduced fundamental shifts in human subsistence practices and sociosymbolic behaviors. Here, we describe the dating of the early pottery from Xianrendong Cave, Jiangxi Province, China, and the micromorphology of the stratigraphic contexts of the pottery sherds and radiocarbon samples. The radiocarbon ages of the archaeological contexts of the earliest sherds are 20,000 to 19,000 calendar years before the present, 2000 to 3000 years older than other pottery found in East Asia and elsewhere. The occupations in the cave demonstrate that pottery was produced by mobile foragers who hunted and gathered during the Late Glacial Maximum. These vessels may have served as cooking devices. The early date shows that pottery was first made and used 10 millennia or more before the emergence of agriculture.

Sensing design and workmanship: the haptic skills of shoppers in eighteenth-century London.

This article explores how eighteenth-century shoppers understood the material world around them. It argues that retail experiences exposed shoppers to different objects, which subsequently shaped their understanding of this world. This article builds on recent research that highlights the importance of shop environments and browsing in consumer choice. More particularly, it differentiates itself by examining the practice of handling goods in shops and arguing that sensory interaction with multiple goods was one of the key means by which shoppers comprehended concepts of design and workmanship. In doing so, it affirms the importance of sensory research to design history. The article focuses on consumer purchases of ceramic objects and examines a variety of sources to demonstrate the role of haptic skills in this act. It shows how different literary sources described browsing for goods in gendered and satirical terms and then contrasts these readings against visual evidence to illustrate how handling goods was also represented as a positive act. It reads browsing as a valued practice requiring competence, patience and haptic skills. Through an examination of diary sources, letters and objects this article asks what information shoppers gained from touching various objects. It concludes by demonstrating how repetitive handling in search of quality meant that shoppers acquired their own conception of what constituted workmanship and design.

Investigating early modern Ottoman consumer culture in the light of Bursa probate inventories.

This study investigates the development of early modern Ottoman consumer culture. In particular, the democratization of consumption, which is a significant indicator of the development of western consumer cultures, is examined in relation to Ottoman society. Sixteenth- and seventeenth-century probate inventories of the town of Bursa combined with literary and official sources are used in order to identify democratization of consumption and the macro conditions shaping this development. Findings demonstrate that commercialization, international trade, urbanization which created a fluid social structure, and the ability of the state to negotiate with guilds were possible contextual specificities which encouraged the democratization of consumption in the Bursa context.

Interpolity exchange of basalt tools facilitated via elite control in Hawaiian archaic states.

Ethnohistoric accounts of late precontact Hawaiian archaic states emphasize the independence of chiefly controlled territories (ahupua'a) based on an agricultural, staple economy. However, elite control of unevenly distributed resources, such as high-quality volcanic rock for adze production, may have provided an alternative source of economic power. To test this hypothesis we used nondestructive energy-dispersive X-ray fluorescence (ED-XRF) analysis of 328 lithic artifacts from 36 archaeological features in the Kahikinui district, Maui Island, to geochemically characterize the source groups. This process was followed by a limited sampling using destructive wavelength-dispersive X-ray fluorescence (WD-XRF) analysis to more precisely characterize certain nonlocal source groups. Seventeen geochemical groups were defined, eight of which represent extra-Maui Island sources. Although the majority of stone tools were derived from Maui Island sources (71%), a significant quantity (27%) of tools derived from extraisland sources, including the large Mauna Kea quarry on Hawai'i Island as well as quarries on O'ahu, Moloka'i, and Lana'i islands. Importantly, tools quarried from extralocal sources are found in the highest frequency in elite residential features and in ritual contexts. These results suggest a significant role for a wealth economy based on the control and distribution of nonagricultural goods and resources during the rise of the Hawaiian archaic states.

Terahertz tomographic imaging of XVIIIth Dynasty Egyptian sealed pottery.

A monochromatic millimeter-wave imaging system coupled with an infrared temperature sensor has been used to investigate historic objects preserved at the Museum of Aquitaine (France). In particular, two-dimensional and three-dimensional analyses have been performed in order to reveal the internal structure of nearly 3500-year-old sealed Egyptian jars.

Crazy for bargains: inventing the irrational female shopper in modernizing English Canada.

Between the 1890s and 1930s, anglophone politicians, journalists, novelists, and other commentators living in western, central, and eastern Canada drew upon established connections among greed, luxury, hysteria, and femininity to describe women who went shopping as irrational. Their motivations for doing so included their desires to assuage feelings of guilt about increased abundance; articulate anger caused by spousal conflicts over money; assert the legitimacy of male authority; and assign blame for the decline of small communities' sustainability, the degradation of labour standards, and the erosion of independent shopkeeping. By calling upon stock stereotypes of femininity, and by repositioning them to fit the current capitalist moment, English-Canadian commentators constructed disempowering representations of women to alleviate their anxieties about what they perceived as the ills of modernization.

American style or Turkish chair: the triumph of bodily comfort.

This article investigates the reciprocal influence of Ottoman Turkish and American interiors in the development of seating furniture. Seating furniture is unique because it involves a direct and physical interaction between the piece of furniture and the body, while at the same time it is part of a public space where social interactions occur. I will argue that the interactions between the Ottoman Turks and Americans are reflected in the way these traditions modified their seating furniture as they sought to mediate cultural, political and social differences between them. The concept of bodily comfort will serve as a common thread in understanding the origin of the expression "American style" (Amerikan stili or Amerikan tarzi) in modern Turkish language, the "Turkish chairs" in Victorian America in the late nineteenth century and the English language use of words such as sofa, ottoman and divan.

A "theatre of rule?" Domestic service in aristocratic households under the Third Republic.

E. P. Thompson developed the notion of "cultural hegemony" to analyse the power of the ruling class over the working class in eighteenth-century England. This article examines the aristocracy's endeavour to maintain its cultural hegemony in the France of the Third Republic. Drawing on the private archives of noble families, it documents servants' roles in supporting the "conspicuous consumption" of their employers, the hierarchy and wages of male and female servants and the language and gestures used in employer-servant interaction. It then looks at working-class responses to nobles' hegemonic ritual of hunting and concludes with discussion of the post-war socio-economic climate in which the distinctive features of domestic service in aristocratic households were gradually abandoned.

Science on a salad plate?: Thinking about the representation of natural history in the Canadian Historic Dinner Service project.

The Women's Art Association of Canada marked the 400th anniversary of John Cabot's "discovery" of Canada (celebrated in 1897) through the production of the "Canadian Historic Dinner Service." The high-profile project, which resulted in a set of hand-painted porcelain dinnerware, was a celebration not only of nation-building, but also of the natural history of the country. Visual reference material provided to the women selected to create the individual pieces included photographs, natural history texts, and illustrations that W.H. Bartlett produced for Canadian Scenery earlier in the century. This article explores this visual reinterpretation of Canada's natural history in order to raise questions about how a recontextualization of scientific material shapes narratives of nation and nature in the 'New World'.

Gas chromatographic, mass spectrometric and stable carbon isotopic investigations of organic residues of plant oils and animal fats employed as illuminants in archaeological lamps from Egypt.

Man's use of illuminants in lamps or as torches to extend the working day and range of environments accessible to him would have been a major technological advance in human civilisation. The most obvious evidence for this in the archaeological record comes from pottery and stone vessels showing sooting due to the use of a wick in conjunction with a lipid-based fuel or illuminant. A wide range of potential fuels would have been exploited depending upon availability and burning requirements. Reported herein are the results of chemical investigations of a number of lamps recovered from excavations of the site of Qasr Ibrim, Egypt. Gas chromatographic, mass spectrometric and stable carbon isotopic analyses of both free (solvent extractable) and 'bound'(released from solvent extracted pottery by base treatment) lipids have revealed a wide range of saturated fatty acids, hydroxy fatty acids and alpha, omega-dicarboxylic acids. Examination of the distributions of compounds and comparisons with the fatty acid compositions of modern plant oils have allowed a range of fats and oils to be recognised. Specific illuminants identified include Brassicaceae (Cruciferae) seed oil (most likely radish oil, Raphanus sativus), castor oil (from Ricinus communis), animal fat, with less diagnostic distributions and delta(13)C values being consistent with low stearic acid plant oils, such as linseed (Linum usitatissimum) or sesame (Sesamum indicum) oils. The identifications of the various oils and fats are supported by parallel investigations of illuminant residues produced by burning various oils in replica pottery lamps. The findings are entirely consistent with the classical writers including Strabo, Pliny and Theophrastrus.
