Migration and Viking Dublin: paleomobility and paleodiet through isotopic analyses

During the early medieval period in Ireland, Dublin was established as the largest Viking settlement on the island in the ninth century AD. A previous biodistance study has suggested that the population of the town consisted of a polyethnic amalgam of immigrant and indigenous. In this study, we use biogeochemistry to investigate paleomobility and paleodiet in archeological human remains from the ninth to eleventh century levels at the sites at Fishamble Street II (National Museum of Ireland excavation number E172), Fishamble Street III (E190) and John’s Lane (E173), as well as twelfth-century remains from Wood Quay (E132). Through radiogenic strontium isotope, stable oxygen, carbon, and nitrogen isotope, and elemental concentration analyses, we investigate the origins of the individuals who lived and died in early and late Viking Dublin. Mean archaeological human enamel and bone isotope values from Dublin are ⁸⁷Sr/⁸⁶Sr = 0.70975 ± 0.00139 (2σ, n = 22), δ¹³C_{carbonate(V-PDB)} = −14.8‰ ± 0.8‰ (1σ, n = 12), and δ¹⁸O_{carbonate(V-PDB)} = −7.2‰ ± 1.0‰ (1σ, n = 12). Archaeological human bone samples exhibit mean δ¹³C_{collagen(V-PDB)} = −20.8‰ ± 0.5‰ (1σ, n = 12) and mean δ¹⁵N_{collagen(AIR)} = +10.0‰ ± 1.7‰ (1σ, n = 12). Comparing these data with archaeological faunal data from Dublin and published data from northern Europe, we argue that there are no clear immigrants from other parts of the North Atlantic, although there is one clear outlier in both origins and diet. Overall, the relative homogeneity in both paleomobility and paleodiet may support models of acculturation in Viking Dublin, rather than a high number of first-generation immigrants or continued migration from Scandinavia.     

Domestic slave trading in St. Croix, 1764–1848

This article deals with domestic slave trading in the Danish (-Norwegian) West Indian colony of St. Croix, focusing on enslaved labourers sold as chattel. It examines the volume and price developments, building upon data on thousands of sales. Crucian slaveholders were willing participants in the domestic slave market, especially during the market’s peak period, c. 1767–1823. Some of them did make a profit from speculation, although evidence of large-scale, professional entrepreneurs is absent. The closing of the transatlantic slave trade did not lead to rising slave prices in the short term, but in the long run it was an important factor in the decline of the market. Finally, the article discusses the impact of the market on enslaved Crucians and their masters, as well as their respective strategies for dealing with it.     

Source of ore fluids at the Kalahari Goldridge deposit, Kraaipan greenstone belt, South Africa: evidence from Sr, C and O isotope signatures in carbonates

The Kalahari Goldridge deposit is located in the Archaean Kraaipan greenstone belt in the north-west province of South Africa. Gold mineralization in this deposit is hosted within banded iron formation which is flanked by a mafic schist in the footwall and clastic metasedimentary units in the hanging wall. Data from carbonate minerals from mineralized veins and bulk rock from the A and D zone ore bodies have helped to define the ultimate origin of the ore-forming fluids and their migration history. Carbon isotope ratios of carbonates from both the A and D zone ore bodies have tight clustering from −7.6 to −5.3‰ that indicates a unique origin for the ore-forming fluids associated with the mineralization at Kalahari Goldridge. The δ¹⁸O values of the carbonates have been influenced by temperature gradients and variable degrees of fluid–rock interaction promoting oxygen isotope exchange between ore fluid and host rocks. Minimum ⁸⁷Sr/⁸⁶Sr ratio values of 0.70354 in mineralized veins are most consistent with ore-forming fluids being relatively pristine with a mantle origin. Strontium and the corresponding ore-forming fluids were most likely derived from mantle-derived magmatic rocks probably represented by the meta-basaltic rocks that underlie the ferruginous package in the Kraaipan greenstone belt. Strontium isotopic composition of vein carbonates show considerable variation in ⁸⁷Sr/⁸⁶Sr ratios ranging from 0.70354 to 0.73914. This is consistent with an ore fluid composition that has been modified by the addition of radiogenic Sr possibly during passage of fluid through siliciclastic country rock concomitant with the observed hydrothermal alteration.     

Using historically informed archaeology: Seventeenth and eighteenth century Hueda/European interaction on the coast of Bénin

The period of the Atlantic slave trade between Africa and European colonies is relatively well documented compared with the historic records of many regions of precolonial Africa. However, this documentation necessarily presents a perspective distilled through European eyes. This paper suggests a methodology influenced byAnnales history for critically analyzing documentary sources in conjunction with a critical interpretation of archaeological remains. Archaeological evidence from recent excavations at the site of Savi, capital of the Hueda kingdom, is contrasted with documentary evidence, facilitating an interpretation of motivations guiding Hueda interaction with European traders and structuring their spatial relationship.     

Archaeology of Slavery in East Africa

African archaeology has primarily been concerned with precolonial Africa. Consequently, the archaeology of colonial and postcolonial Africa has been neglected, in spite of the fundamental importance of how Africa's relationships with Eurasia after 1488 shaped its history. Although the slave trade was an important aspect of post-sixteenth century experiences of Africans, current research methodologies make the archaeology of slavery in Africa nearly impossible because evidence of the slave trade or slavery--including slave quarters, cemeteries, holding areas, shackles, and dungeons--can be interpreted in various ways. In this article I argue that the archaeology of slavery and the slave trade in Africa is possible. Like history and economics, archaeology is well placed to investigate slavery in Africa as it already does effectively in the Americas. Using the study of defensive rock shelters in Southeast Kenya as an example, I propose that the systematic archaeology of slavery in Africa is not only possible, but also should break new grounds and develop an innovative methodology for studying slavery. L'archéologie africaine a été principalement concernée par l'Afrique précoloniale. Par conséquent, l'archéologie de l'Afrique coloniale et postcoloniale a été oubliée, malgré l'importance fondamentale de la façon dont les rapports de l'Afrique avec Eurasia après 1488 ont tracé son histoire. Bien que le commerce d'esclaves soit un aspect important des expériences africaines du post-seizième siècle, les méthodologies courantes de recherches rendent l'archéologie de l'esclavage en Afrique presque impossible car l'évidence du commerce ou de l'esclavage - comprenant les quarts, les cimetières, les camps, des cachots, et des donjons des esclaves - peut être interprété de diverses manières. Dans cet article, j'argue du fait que l'archéologie de l'esclavage et le commerce d'esclaves en Afrique est possible. Comme l'histoire et les sciences économiques, l'archéologie est bien placée pour effectuer l'étude de l'esclavage en Afrique comme elle l'est déjà efficacement en Amérique. En utilisant l'étude des abris rocheux défensifs au Kenya du sud-est comme exemple, je propose que la systématique de l'archéologie de l'esclavage en Afrique est non seulement possible, mais devrait également permettre de franchir de nouveaux pas et de développer une méthodologie innovatrice dans l'étude de l'esclavage.     

The transatlantic Muslim diaspora to Latin America in the nineteenth century

Since the 16th century, African Muslims figured prominently among the slave population of the Americas. While the number of Muslims pulled into the trade has always been a matter of speculation, lists of Africans rescued from slave ships provide us with some clues about the size and direction of the Muslim diaspora to Latin America in the 19th century. Based on an analysis of tens of thousands of names recorded in these lists, this essay argues that the majority of Muslim captives leaving Africa departed from Upper Guinea and suggests that Cuba was the center of the forced Muslim diaspora in the Americas. It traces the transatlantic links that connected particular regions of embarkation in Africa to their counterparts in Latin America and considers the implications of those connections for religious and cultural change within 19th-century slave populations. The essay challenges in important ways the colonial/postcolonial divide in Latin American history and uses Islam to pose important questions about the dynamics of social change across slave societies.     

Securing the “Interests” of the South: John Mitchel,A.G. Magrath,and the Reopening of the Transatlantic Slave Trade

Traditionally scholars have downplayed the importance of southern calls to reopen the transatlantic slave trade in the 1850s. Those who have paid serious attention to this effort see it as another endeavor by aristocratic planters to enshrine their social, economic, and political power in the antebellum South. The advocates were, as one puts it, “no champions of the common white man.” Two Irish-American leaders who supported the reopening, John Mitchel and Andrew Gordon Magrath, complicate this view of the attempt as just a planters’ plot. Their actions and opinions indicate that some proponents did see importing African slaves as something that would benefit all whites and not just the elite, and, as a result, protect the overall “interests” of the South. Mitchel and Magrath's support of Ireland and Irish immigrants and their opposition to British power influenced their positions on the matter.     

‘Enslaving Christians’: Greek slaves in late medieval Cyprus

This article explores the functions and perceptions of slavery in late medieval Cyprus, paying particular attention to attitudes towards Christian, and especially, Greek slaves. The island had a predominantly Orthodox population, and received a substantial influx of Greek slaves in the fourteenth and fifteenth centuries. Evidence from notarial accounts, estate surveys and chronicles is utilized to examine the ways in which ‘Greek’ slaves were defined and identified. The article investigates whether belonging to this perceived group played a part in shaping the slaves’ paths towards manumission. The context (urban or rural) in which Christian slaves served also influenced attitudes towards labour use in various ways.     

Spatial variation of biologically available strontium isotopes (Sr/Sr) in an archipelagic setting: a case study from the Caribbean

This paper presents the results of strontium (Sr) isotope analysis of modern and archaeological animal remains and modern plant samples from the Caribbean region. The goal is to assess if patterns of human mobility can be determined from the archaeological record in an archipelagic setting. The range of variability and spatial distribution of biologically available strontium isotope signatures is reported and data evaluated to determine if sufficient heterogeneity exists to permit the identification of mobility despite the presence of potentially large contributions of marine strontium in island and coastal ecosystems. The (is)landscape is divided into several sub-regions based on the age and lithology of underlying geology and the variability of ⁸⁷Sr/⁸⁶Sr ratios is reported as; mean ⁸⁷Sr/⁸⁶Sr ± 2 standard deviations, number of samples: 1) Volcanic and Intrusive rocks (0.7077 ± 0.0019; n = 162); 2) Cretaceous–Miocene Limestone (0.7085 ± 0.0009; n = 50); 3) Pliocene–Quaternary Limestone (0.7091 ± 0.0004; n = 54); 4) Sedimentary Deposits (0.7094 ± 0.0015; n = 16); 5) Metamorphic Deposits (0.7104 ± 0.0014; n = 6). There are substantial differences between expected ⁸⁷Sr/⁸⁶Sr values based on associated geology and measured ⁸⁷Sr/⁸⁶Sr in flora and fauna samples. These differences emphasize the importance of focusing on bioavailable strontium, as opposed to geological proxies, for estimations of Sr isotope ranges, especially in archipelagic environments. While some overlap exists between the ⁸⁷Sr/⁸⁶Sr ranges of certain sub-regions, other sub-regions possessed limited variation and could be distinguished based on strontium isotope data. This spatial patterning of biologically available strontium indicates that strontium isotope analyses can be successfully applied to the archaeological study of human mobility within the Caribbean region.     

Immigration to Tikal,Guatemala: Evidence from stable strontium and oxygen isotopes

This paper presents strontium and oxygen isotopic measurements on archaeological human teeth from the ancient Maya city of Tikal, Guatemala, that illuminate the role that migration played in the history of the state. Stable strontium isotope ratios of human teeth parallel the bedrock geology of the location where foods were grown, while stable oxygen isotope ratios reflect the sources of water imbibed, and track geographic variation in the isotopic composition of rain water. Because tooth enamel forms during childhood and is not remodeled during life, we can identify foreign-born individuals at Tikal by their outlying strontium and oxygen isotope ratios. These data indicate that approximately 11–16% of the sampled Tikal skeletons spent their childhood at distant sites. Most of the migrant burials date from the Early Classic period and are high status contexts. Several royal burials demonstrate long distance movement of both males and females, and shed light on the identification of epigraphically-known individuals. Yet, both Early and Late Classic migrants are found in lower status domestic burials. Interaction with distant peers was important in the rise of the Tikal polity, however, immigration from all social tiers contributed to the city’s rapid population growth.
