Obsidian provenance studies in Colombia and Ecuador: obsidian sources revisited

The field occurrences, elemental compositions and formation ages of Colombian and Ecuadorian obsidians are revisited. It is shown that the regional sources of this raw material are linked to two major volcanic structures: the Chacana and the Paletara calderas, localised on the eastern cordillera of Ecuador and on the central Andean cordillera of south Colombia respectively. Seventy-two samples were analysed by inductively coupled plasma-atomic emission spectroscopy (ICP-AES), inductively coupled plasma-mass spectrometry (ICP-MS) and/or particle induced X-ray emission (PIXE). The same 10 types of elemental compositions were identified independently from ICP and PIXE. Four of these types were previously unknown. The formation ages of these obsidians previously determined by fission tracks dating are in the range 0.17–1.58 Ma at Chacana and 3.46–4.27 Ma at Paletara. Most Colombian and Ecuadorian pre-Hispanic artefacts present elemental compositions compatible with a Chacana- or Paletara-derived origin of the raw material. However, some of them present fission track ages discordant with the present-day known obsidian occurrences, which implies that the regional source inventory is not yet exhaustive.     

Culture <Emphasis Type="Italic">Versus</Emphasis> Civilisation la Genèse D’une Opposition

Closely linked to the concept of history, the notion of culture becomes a collective singular during the last third of the xviii ^th century. The German idea of culture did not immediately come into opposition with the notion of civilization and both terms were for a long time almost identical in meaning. What does the polemical orientation of the German notion of culture reveal from 1880–1890? First, the crumbling of the idealistic neo-kantian pattern of self-determined cultivated person as an end in itself (the so-called Selbstbildung); second, the growing moral condemnation of the empty spirit of the time. This double process reaches its apogee full of hatred during World War I.     

La fabrique de la perpétuité

TheTrésor des chartes is probably one of the best preserved single collection of archives of the ancient French monarchy. Paradoxically, however, it was never part of a central record office in the modern sense. This large and confused mass of documentation slowly emerged as a records collection during the XIII^th century. Although it seemed to follow the construction of a State administration, it was already inactive by the middle of the XIV^th century. Its records and charters, prestigious and inaccessible, were kept in the Sainte-Chapelle of Paris, close to the relics of the Passion bought by Louis the Ninth. As a record of the past it played a crucial role in the social construction of a notion of «perpetuity» suitable to the domanial and dynastic ideals of the monarchy. The ambiguities of this medieval heritage became obvious in the early modern period. Although there were a large number of inventories and classifications of theTrésor des chartes, it was never able to incorporate the other State records. The Republic inherited a majestic sanctuary which can certainly be described as a piece of shared memory, but which is unable to summarize the genesis of the Nation.     

A Father's Perspective on Bridewealth in the Making of the Transnational Papua New Guinean Household

That people value ‘people’ over ‘things’ is argued often by anthropologists, but how people value specific forms and qualities of relations as they do in the example of bridewealth is less so. I explore the perspective of Papua New Guinean-born fathers in Australia as they advocate innovations in bridewealth traditions and thereby enable daughters to marry for love, cultivate a companionate marriage, and create a Papua New Guinean household. Past generations gauged the worth of traditional bridewealth by the quantity and distribution of items given and the number of exogamous clan connections forged as an index of past and future relations between clans. The current generation judges the value of even alternate forms of bridewealth for making new possibilities for those who share in it. If bridewealth enables the transnational household to emerge as the unit of decision making that replaces the clan, then innovations in bridewealth support, rather than undermine, a new normativity of companionate marriage that empowers that much wider net of kin. Drawing on a theory of value as the importance of social action towards the goal of the new normativity of the transnational household, I show how choosing a spouse is cultivated by women's fathers who refuse bridewealth, as often as it is by their husbands who provide new forms of wealth at marriage.     

Sexing cattle horn‐cores: problems and progress

It has long been recognised that cattle horn‐cores are sexually dimorphic, and many methods have been developed using archaeological material for differentiating between specimens belonging to cows, bulls and oxen. Whilst these techniques have been adopted widely by zooarchaeologists, in particular those studying medieval and post‐medieval tannery and horn‐working assemblages, they are highly subjective and their reliability has never been tested using material from cattle of known sex. This paper seeks to redress the balance. It presents the results of a study of 19th and 20th century cattle horn‐cores, from animals of known age, sex and breed, which were examined and measured in order to test the validity of traditional horn‐core sexing techniques. Previously claimed traits of sexual variation are here refuted, and a new metrical threshold for separating the males and females of ‘medium‐horned’ and ‘long‐horned’ types are presented.

Pre-Columbian congenital syphilis from the late antiquity in France

Today, exactly 500 years after the discovery of America, there is still a lot of controversy about the history of syphilis in Europe, especially about the Columbian and pre-Columbian hypotheses. This paper presents evidence for the presence of venereal treponematosis in the late Antiquity in France. The case that we examined comes from the necropolis of Costebelle (3rd-5th centuries AD; Hyères, Var, France). Grave no. 1 contained the well-preserved skeleton of a relatively old woman with the skeletal remains of an approximately 7-month-old fetus in her pelvic cavity. The osseous lesions of the fetal remains can be described in four groups: periosteal appositions on the skull vault (frontal and parietal); signs of periostitis on the long bones (bilateral cortical irregularities, predominantly on the left side, which affect first of all tibiae, femora, fibulae, radii and humeri, particularly in the metaphyseal region); some infraperiosteal detachment reminiscent of an infraperiosteal haematoma surrounding the distal extremity of the left forearm and the left hand; and finally, the irregular lesions of the humeral distal and proximal tibial metaphyses reminded us radiologically of Wimberger's signs. The most probable diagnosis of all the lesions mentioned above is that of a precocious congenital syphilis. This case consists of an argument against the epidemiological theories about the migration of Treponema pallidum from the New World back to the Old World starting at the end of the 15th century.     

The Origin of African Sheep: Archaeological and Genetic Perspectives

Indigenous African sheep genetic resources have been classified into two main groups, fat-tailed and thin-tailed sheep. The fat-tailed sheep are the most widely distributed, being found in a large part of North Africa (from Egypt to Algeria) and in Eastern and Southern Africa (from Eritrea to South Africa). The thin-tailed sheep are present mainly in Morocco, Sudan and in West Africa. African sheep were domesticated outside Africa. They share a common ancestry with European and Asian sheep. Archaeological information supports separate introductions and dispersion histories for the African thin-tailed and fat-tailed sheep. The first sheep entered Africa via the Isthmus of Suez and/or the southern Sinai Peninsula, between 7500 and 7000 BP. They were likely of the thin-tailed type. Fat-tailed sheep entered Africa through its northeastern part and the Horn of Africa. Mitochondrial DNA analysis supports a common maternal ancestral origin for all African sheep, while autosomal and Y chromosome DNA analysis indicates a distinct genetic history for African thin-tailed and sub-Saharan fat-tailed sheep. The main ancestral population of southern African fat-tailed sheep likely originated in East Africa. Further work is needed to assess the possible dispersion of sheep from western Africa to the southern African regions.     

Domesticating Animals in Africa: Implications of Genetic and Archaeological Findings

Domestication is an ongoing co-evolutionary process rather than an event or invention. Recent zooarchaeological and animal genetics research has prompted a thorough revision of our perspectives on the history of domestic animals in Africa. Genetic analyses of domestic animal species have revealed that domestic donkeys are descended from African ancestors, opened a debate over the contribution of indigenous aurochs to African domestic cattle, revealed an earlier and possibly exogenous origin of the domestic cat, and reframed our vision of African dogs. Genetic diversity studies and mapping of unique traits in African cattle, sheep, goats, pigs and chickens indicate adaptations to regional environmental challenges and suggest hitherto unknown and complex patterns of interactions both among Africans and with Southwest Asia and other Asian regions on the Indian Ocean. This article argues against the static perspective on domestication as invention and for viewing it as a dynamic, locally based and continuing process.
