Recording Art on Neolithic Stelae and Passage Tombs from Digital Photographs

Current research on the carved, pecked, and incised art of Neolithic stelae and passage tombs in Brittany and Ireland has required the creation of a new method of recording. This new technique has several advantages over traditional recording methods (tracing and rubbing): It is noninvasive and it allows very precise data acquisition, as well as providing an accurate record of the carved representations. The present paper describes the four stages of the process and presents its analytical capacities, using as an example the carved axe from the Table des Marchands passage tomb.     

Study of interactions between polyethylene glycol and archaeological wood components by C high-resolution solid-state CP-MAS NMR

While use of polyethylene glycols, PEG, polymers for archaeological wood conservation has been well established, there is almost no study of such composite materials with carbon thirteen high-resolution solid-sate NMR. We demonstrate that NMR is an useful analytical tool to characterize rapidly samples of conserved wooden objects. By choosing an appropriate value of the contact time (from 3 to 5 ms) for which the PEG component gives only a small residual NMR signal in the CP-MAS experiment, it is possible to edit selectively the spectra of the wood components. It allows one to visualize the degradation extent of the archaeological wood even when the conservation processes have been already applied. Moreover, by studying the kinetics of CP-MAS experiments, the time constants, T_1ρH and T_CH values for PEG moiety were computed. From these data, it is shown that either in the crude commercial product or in incorporated in archaeological woods, two components are present and they are the signatures of crystalline (or ordered) and amorphous (or disordered) molecular domains. Moreover, it was shown in the archaeological woods that almost 30% of PEG was in close molecular interactions with lignins. This study is the first evidence that the PEG in conserved wood can interact at a molecular level with wood components. It also demonstrates that the PEG diffuses inside the residual cell walls of archaeological wood. This data are important for scientists in charge of process development for the conservation of wooden artifacts.     

Nabataean or not? The ancient necropolis of Dumat. First stage: a reassessment of al‐Dayel's excavations

Two reports on excavations carried out in 1985–1986 by archaeologist Khaled Abdulaziz al‐Dayel and published in the journal Atlal (1988, 1986) have revealed the existence of ‘Hellenistic tombs’ in the Dūmat al‐Jandal oasis (ancient Adummatu/Dumat/Dumata) in northern Saudi Arabia. Although attributed more precisely to the Nabataeans by Khalil al‐Muaikel (1994), these tombs nevertheless appear not to have interested specialists of this historical period in the least. Moreover, a re‐examination of the architectural data and of the grave‐goods indicates the difficulty of establishing a link between the unearthed remains and a purely ‘Nabataean’ cultural sphere (i.e. of the Petra type). This study therefore attempts to reassess published archaeological data, formulate questions on the Nabataean presence in the oasis, and also to demonstrate the relations connecting Dumat to the great Levantine and Mesopotamian cultural spheres between the first century BC and the second century AD.     

“To see things in an objective light”: the Dakota Access Pipeline and the ongoing construction of settler colonial landscapes

ABSTRACT

This paper examines the discourses used by proponents of the Dakota Access Pipeline (DAPL) as claims of universality to which the Standing Rock Sioux tribe and allied activists mounted a movement of opposition in 2014–2017. We position our analysis within the historical context of Lakota and Dakota resistance to settler colonialism, which has endured since the nineteenth century. From publicly available texts circulated by key actors in the conflict over the construction of this pipeline project, we identify themes that proponents of this project drew upon to articulate their representations of the land as universal. We suggest that claims like these, when naturalized in practice, have historically materialized in settler colonial landscapes. With the concept of settler colonial landscapes, we focus on ways of seeing and representing places that have facilitated the dispossession of Indigenous people from their territory as well as the construction of a settler-dominated community. In this way, we develop a cultural geographical understanding of the ongoing construction of settler colonial landscapes as a process dependent on claims to neutrality and objectivity.
