Creating an Empire of Informers

In the year 672 BC, Esarhaddon, King of Assyria imposed a succession covenant (adê) on his subjects, the inhabitants of the Assyrian Empire. This covenant required the empire’s population to monitor one another, and themselves, for signs of disloyalty to the monarch and his chosen successor, Ashurbanipal. This study examines the aims and outcomes, desired and undesired, of imposing this duty of vigilance across the extent of the Assyrian Empire

Newly Discovered Studio Photographs of Revolutionary Anthropologist Llewellyn Lemont Loud

Llewellyn L. Loud is an iconic figure in California and Great Basin anthropology, a man who made significant contributions to the field but whose path was as unique as he was. He made his way from Maine to U.C. Berkeley, and after holding a number of positions, including as guard and janitor, worked as a senior preparator and then went on to excavate some of the most important archaeological sites in the region. As described by his supervisor A. L. Kroeber, Loud was a singular individualósolitary, stubborn, independent, and loyaló as well as being a humanist and open socialist at a time when such beliefs were far from mainstream. Six newly discovered studio photographs recently found at Washington State University are revealing of Loudís unique character. The details of this coincidental discovery are discussed here, along with relevant background information about Loud and early twentiethcentury studio portraiture

Astrometry and geodesy with radio interferometry: experiments, models, results

Summarizes current status of radio interferometry at radio frequencies between Earth-based receivers, for astrometric and geodetic applications. Emphasizes theoretical models of VLBI observables that are required to extract results at the present accuracy levels of 1 cm and 1 nanoradian. Highlights the achievements of VLBI during the past two decades in reference frames, Earth orientation, atmospheric effects on microwave propagation, and relativity.Comment: 83 pages, 19 Postscript figures.

Constraining mid to late Holocene relative sea level change in the southern equatorial Pacific Ocean relative to the Society Islands, French Polynesia

Precisely quantifying the current climate-related sea level change requires accurate knowledge of long-term geological processes known as Glacial Isostatic Adjustments (GIA). Although the major postglacial melting phase is likely to have ended ∼6–4 ka BP (before present), GIA is still significantly affecting the present-day vertical position of the mean sea surface and the sea bottom. Here we present empirical rsl (relative sea level) data based on U/Th dated fossil corals from reef platforms of the Society Islands, French Polynesia, together with the corresponding GIA-modeling. Fossil coral data constrain the timing and amplitude of rsl variations after the Holocene sea level maximum (HSLM). Upon correction for isostatic island subsidence, we find that local rsl was at least ∼1.5 ± 0.4 m higher than present at ∼5.4 ka. Later, minor amplitude variations occurred until ∼2 ka, when the rsl started dropping to its present position with a rate of ∼0.4 mm/yr. The data match with predicted rsl curves based on global ice-sheet chronologies confirming the role of GIA-induced ocean siphoning effect throughout the mid to late Holocene. A long lasting Late Holocene highstand superimposed with second-order amplitudinal fluctuations as seen from our data suggest that the theoretical predicted timing of rsl change can still be refined pending future calibration

Metabolomics-Based Analysis of Miniature Flask Contents Identifies Tobacco Mixture Use among the Ancient Maya

A particular type of miniature ceramic vessel locally known as “veneneras” is occasionally found during archaeological excavations in the Maya Area. To date, only one study of a collection of such containers successfully identified organic residues through coupled chromatography–mass spectrometry methods. That study identified traces of nicotine likely associated with tobacco. Here we present a more complete picture by analyzing a suite of possible complementary ingredients in tobacco mixtures across a collection of 14 miniature vessels. The collection includes four different vessel forms and allows for the comparison of specimens which had previously formed part of museum exhibitions with recently excavated, untreated containers. Archaeological samples were compared with fresh as well as cured reference materials from two different species of tobacco (Nicotiana tabacum and N. rustica). In addition, we sampled six more plants which are linked to mind-altering practices through Mesoamerican ethnohistoric or ethnographic records. Analyses were conducted using UPLC-MS metabolomics-based analytical techniques, which significantly expand the possible detection of chemical compounds compared to previous biomarker-focused studies. Results include the detection of more than 9000 residual chemical features. We trace, for the first time, the presence of Mexican marigold (Tagetes lucida) in presumptive polydrug mixtures

Disease and Healing in Ancient Societies: Dental Calculus Residues and Skeletal Pathology Data Indicate Age and Sex-Biased Medicinal Practices among Native Californians

The health of humans is intricately linked to the substances - both food and non-dietary items -we ingest. Adverse health outcomes related to smoking of products like tobacco and other psychoactive substances are clearly established in modern populations but are less well understood for ancient communities. Grasping these dynamics is further complicated by the curative, religious, and medicinal context of many of these substances, which have often been commodified, refined, and altered in recent history. As part of a larger collaboration with the Muwekma Ohlone Tribe dedicated to understanding medicinal plant use among native Californians, we present a summary of new metabolomic data from three Middle and Late-period ancestral heritage Ohlone sites: Thámien Rúmmeytak (CA-SCL-128), ’Ayttakiš ’Éete Hiramwiš Trépam-tak (CA-ALA-677/H/H), and Sii Tuupentak (CA-ALA-565/H/H). Using a UPLC-MS platform, we analyze chemical residues from 95 human dental calculus samples from 50 burials. Employing multivariate statistics, we co-analyzed demographic and skeletal pathology data with chemical residue profiles. We considered skeletal markers for a series of oral and postcranial health conditions. Results indicate sex and age biases in consumption patterns. Periodontitis stands out as the most significant local factor for changes in the oral metabolome. However, while chemical markers of oral diseases may be related to pathogen activity, associations between residues and postcranial conditions such as osteoarthritis suggest traditional curative practices and the ingestion of medicinal substances. Hence, our study yields new insights into the broader context of illness and healing in the past
