A Better Shade of Black: Effects of Manufacturing Parameters on the Development of Ancient Black Bronzes*

Copper alloys with controlled contents of Sn, Ag and Au were treated with methods and solutions that mimic those used in ancient and traditional procedures for the production of black bronze. Examination of the resulting patinas with colorimetry, SEM–EDS, TEM, Raman spectroscopy and XRD revealed no systematic differences according to the fabrication method, whereas patina homogeneity and colour in those alloys that did not contain precious metal were affected by superficial work. Patina microstructure determines adherence and coverage, and depends upon the solution used irrespective of the alloy composition, but the colour of the patina is mainly related to the alloy composition. Gold promotes the development of cuprite, slowing the oxidation to tenorite in the corrosion process. Gold additions produce a more uniform patina as well as a desirable blue–black tone, which is likely to have been a factor in alloy selection.

Equal Rights and Individual Freedom: Enlightenment Intellectuals and the Lascasian Apology for Black African Slavery

Juan Antonio Llorente's edition of Bartolomé de Las Casas's writings, Colección de las obras del venerable Obispo de Chiapa, Don Bartolome de las Casas, defensor de la libertad de los Americanos, illustrates how Las Casas was perceived and condemned in the early decades of the nineteenth century. In this article, I seek to explain why and in what ways Bartolomé de Las Casas's early propositions on African slavery played a fundamental role in Juan Antonio Llorente's edition of Colección, an ambitious editorial work that involved much more than selection, editing, and publication. By approaching the Colección's production and reception from the perspective of book history, I explore how Llorente's Colección reflects the role that colonial affairs and race had in the challenges faced by European rule and white hegemony.     

Approaching the Approaches

Abstract

Students of political theology need a broad introduction to, and some understanding of how to distinguish between, varying approaches to the discipline. This article argues that differing approaches should be introduced in ways which emphasize the historical, theological, geographical, and ecclesial situatedness of their practitioners. Such introduction to the situatedness of various approaches should not pretend to be objective, but should be sympathetic. Those teaching political theology should also carefully incorporate their own situatedness, showing students how they are working within particular approaches themselves without reducing their teaching to advocacy for their own approaches. The proposal for teaching political theology argued here focuses on inviting students to become active practitioners of political theology, instead of mere consumers of information about the discipline.     

Engendering space: Ballroom culture and the spatial practice of possibility in Detroit

This article examines the ways in which Black lesbian, gay, bisexual, and transgender (LGBT) members of the Ballroom community create black queer space to contend with their spatial exclusion from and marginalization within public and private space in urban Detroit, Michigan. Existing in most urban centers throughout North America, Ballroom culture is a community and network of Black and Latina/o LGBT people. In this ethnography, I delineate the multiple functions of two mutually constitutive domains of Ballroom culture, kinship (the houses) and ritualized performance (the ball events). I use queer theories of geography and draw from Sonjah Stanley Niaah's notion of performance geography to examine the generative socio-spatial practices that Ballroom members deploy to forge alternative possibilities for Black LGBT life in Detroit. In many ways, members of the Ballroom community work to challenge and undo the alienating and oppressive realities of built environments in urban centers by undertaking the necessary social and performance labor that allow its members to revise and reconfigure exclusionary and oppressive spatial forms.     

Private Mark Graham,un/known soldier: not just any body can be a citizen

On 4 September 2006, Private Mark Anthony Graham, a 33-year-old black Canadian, was killed in Afghanistan in a so-called friendly fire incident. An elite athlete prior to his military career, Graham, who was born in Jamaica and grew up in Hamilton, Ontario, had also been a member of the Canadian 4 × 400-metre relay team that competed in the 1992 Olympic games. This article examines the mainstream television and print media accounts that emerged following Private Graham's death to explore the connections between race, masculinity and discourses of national belonging. For example, media narratives emphasized Graham's physicality and track and field career, rather than his status as a citizen-soldier who died in the service of his country. I argue that the prominence ascribed to Graham's corporeality signals his racial alterity, a delineation which facilitates his exclusion from white settler society. Moreover, beyond revealing the enduring legacy of Canada's history of anti-black racism, I suggest that the media's treatment of Private Mark Graham is indicative of the reconfiguration of white cultural nationalism in post-9/11 narratives of citizenship and Canadian identity and efforts to reinstate white men as the true embodiment of masculine heroism and patriotism.

Analysis of ante mortem trauma in three modern skeletal populations

When archaeological skeletons are assessed, the prevalence (and patterns of bone involvement) of trauma is important. The number and pattern of fractures can be used to gain insight into the occurrence of interpersonal violence, workload and living conditions. However, the question remains as to how these results should be interpreted—such as what constitutes high or low levels of trauma? The aim of this study was to investigate the occurrence of trauma in a population of modern Greeks living in Crete, as well as South African (SA) whites and blacks in the Pretoria Bone and Raymond Dart collections. The sample comprised mostly of older individuals (n = 90–100 within a sex‐population group). Each skeleton was studied for healed trauma. For the vertebrae, only spondylolysis was assessed. In the Greek sample, it was found that 42% of the males and 46% of females had at least one fracture, with corresponding figures of 63 and 44% for SA whites and 83 and 69% for SA blacks. Radius, rib and femur fractures were most common in Greeks, with skull, radius and ribs most common in SA whites and skull, ulna and ribs in SA blacks. These prevalences of trauma are high, but the composition of the samples (mostly of lower socio‐economic origin) should be kept in mind. It may also be questioned whether these individuals reflect the society as a whole. It seems that the fractures in Greeks are mostly related to old age due to falls and accidents (radius and hip fractures), while the SA black sample reflects high prevalences of interpersonal violence (such as cranial vault and ulna fractures). The SA white sample follows a comparatively moderate pattern of trauma. These comparative figures may be useful when assessing trauma in other skeletal populations.
