Reconsidering Yeha,c. 800–400 BC

Yeha, in Tigray, is the most impressive site with evidence for South Arabian influence dating to the first millennium BC in the northern Horn of Africa (Eritrea and northern Ethiopia). The evidence from this site was used to identify a ‘Pre-Aksumite’ or ‘Ethiopian-Sabean’ Period (mid-first millennium BC) when an early Afro-Arabian state apparently arose in the region. A ‘Pre-Aksumite Culture’, characterised by South Arabian elements, was also suggested as a distinctive archaeological culture in northern Ethiopia and Eritrea. However, recent fieldwork in these countries suggests that a Pre-Aksumite culture actually did not exist and South Arabian features were restricted to a few sites, which were scattered in a mosaic of different archaeological cultures in the first millennium BC. This hypothesis is tested through a comparison between the ceramics from Yeha and those from Matara and other sites of the first millennium BC in Tigray and Eritrea.     

Acknowledging the Racial State: An Agenda for Environmental Justice Research

Abstract:  This paper argues that environmental justice scholars have tended to overlook the significance of the state's role in shaping understandings of race and racism, and argues for the use of critical race theory to deepen insight into the role of the state in both fostering and responding to conditions of racialized environmental injustice. Critical race theory offers insights into both why and how the state manages racial categories in such a way as to produce environmental injustice, and how the state responds to the claims of the environmental justice movement. Closer attention to the interplay between the racial state and the environmental justice movement as a racial social movement will yield important insights into the conditions, processes, institutions and state apparatuses that foster environmental injustice and that delimit the possibilities for achieving environmental justice in some form or another.     

New Light on the Development of Chalcolithic Metal Technology in the Southern Levant

Several decades after the discovery of the spectacular Nahal Mishmar Hoard (a collection of cast metal goods, some quite ornate, found in a cave high in the cliffs of the Judean Desert) many important questions about Chalcolithic metallurgy in the southern Levant remain unanswered. What is the origin of the materials used? Where were the final goods produced and what were the dynamics of production? In fact, new questions have also arisen as recent discoveries force us to reconsider previous interpretations of Chalcolithic metallurgy and the societies within which it evolved. Such will be the focus of this paper.     

Sourcing temper sands in ancient ceramics with U–Pb ages of detrital zircons: a southwest Pacific test case

Through use of methodology common in sedimentary geology, we apply U–Pb ages of detrital zircons to source nonlocal temper sand in an ancient ceramic assemblage recovered from Roviana Lagoon of the New Georgia Group in the Solomon Islands. Most potsherds from the Roviana Lagoon contain local volcanic sand as temper, but a small number of sherds contain anomalous granitic temper sand that does not appear to be local. To determine the origin of the anomalous temper, ages of zircons from the anomalous Roviana sherds are compared with ages of zircons in materials from Lizard Island off the Queensland coast and in sand from Muyuw Island in the Solomon Sea where generically similar granitic sands occur. U–Pb analyses of grains from the Roviana sherds yield Middle Miocene ages, while analyses of grains from Lizard Island granitic bedrock, sand, and local potsherds yield much older Permian-Triassic ages, disproving any possibility that the Roviana sherds were derived from Lizard Island, but suggesting local production of the Lizard Island sherds. Ages of grains in a sand sample from Muyuw Island are nearly identical to the ages of grains in the Roviana sherds. All grains in the Muyuw sand are Middle Miocene in age, overlapping closely with the Roviana age population. This strong similarity in detrital zircon signals indicates that the Roviana temper was likely derived from Muyuw Island sands. Our test case for the use of U–Pb ages of detrital zircons in sourcing temper sands is of only regional significance, and not of intrinsic global interest. The methodology, however, should find wide applicability for sourcing temper sands in many parts of the world, for it provides more specific data for the origins of tempers than either petrographic or chemical analysis.     

An experimental micromorphological investigation of bedding construction in the Middle Stone Age of Sibudu,South Africa

We conducted experiments to compare the micromorphological signatures of modern burnt sedge and grass bedding to laminated layers of carbonized material and phytoliths in Middle Stone Age deposits at the shelter, Sibudu. The experiments were designed to clarify the formation processes associated with the laminated layers and to investigate whether these previously identified layers of bedding were deliberately burned or not. The results indicate that the laminated layers were most likely produced by human activity related to the construction, maintenance and burning of bedding. Furthermore, our experiments demonstrate that large volumes of vegetal material could have produced the relatively thin, archaeological deposits of burnt bedding.
