A low-cost and computer-controlled graphitization system connected to an elemental analyzer (EA) has been designed and built at the NTUAMS Lab. This semiautomatic system equips 6-unit reactors for the graphitization of CO2 with H2 on the iron catalyst. The entire procedure takes about 7 hours for iron conditioning, sample combustion and loading, and graphitization. The system can produce good-quality graphite for samples containing 0.5–1.6 mg carbon mass, with the pressure yield of graphitization ranging from 57.7% to 87.1%. The average values of OXI and OXII agree well with the consensus value, but the result of ANU sucrose was observed to be slightly higher than the reported one. The background samples of anthracite over ten months yielded an average of 0.38±0.10 pMC (n=21) corresponding to a 14C age of 45 kyr BP. Intercomparison samples L and M of FIRI exhibit that the measured 14C ages are almost identical to the consensus values and have a small spread in these values. The system has been carrying out graphitization for total organic carbon (TOC) of peat samples, and providing a more efficient and convenient way for AMS 14C dating.

This study documents three chapel furnishings dating from around 1500 belonging to the Edgcumbe family at Cotehele, Cornwall, south-west England, and discusses their survival during the Protestant Reformation and beyond. The textiles were exhibited to the Society of Antiquaries of London by W H St John Hope, FSA and the text of his presentation was published in the Proceedings of the Society in 1912–13. The present article brings together the numerous other historic writings concerning the textiles. Their possible origins are explored and assessed in context with pieces of similar date. Observations of their original making and later changes are recorded, while interpretations by historians of this period are put forward for consideration. The rarity of survival of the textiles and their documented history is acknowledged.

En este trabajo se presentan los resultados de estudios experimentales realizados en pastas cerámicas con el objetivo de comprender las elecciones técnicas realizadas por los grupos cazadores-recolectores que habitaron el curso inferior del Río Colorado (transición pampeano-patagónica oriental) en los últimos 2000 años aP aproximadamente. A tal efecto, con la guía de ceramistas locales, se realizaron ensayos tanto en el campo como en el laboratorio, empleando materias primas (arcillas y arenas) obtenidas del área de estudio. Durante las tareas de campo se realizó el testeo inicial y la cocción de las materias primas, actividades que se repitieron en el laboratorio. A esto se agregó una batería de estudios arqueométricos (e.g., petrografías, DRX, FTIR, SEM-EDAX) cuyos resultados fueron comparados con la información arqueológica del área. En este sentido, la composición de las materias primas, las temperaturas y condiciones de quema, así como los patrones tecnológicos de las pastas experimentales, son concordantes con las registradas en las cerámicas arqueológicas. La integración de estos datos indicaría la producción preponderantemente local de las vasijas como también la transmisión de una práctica alfarera a lo largo del Holoceno tardío.

This essay has two objectives. First, it acknowledges and situates the contribution of Ethel Ann Burton-Brown (1868–1927) to the history of the archaeology of the Roman Forum as it was excavated between 1898 and 1905 under the direction of Giacomo Boni (1859–1925). Her English-language handbook on the discoveries, now overlooked in literature on Boni, showcased her education at Girton College, her experience with traditional cultures such as those of northern India, and her understanding of established and newly emerging methods of classical archaeology. Unlike Esther van Deman and Eugénie Sellers Strong, who embraced careers in archaeology just years after Burton-Brown's publication, she did not pursue working in the discipline because of her personal situation. Secondly, it investigates the manner in which Burton-Brown received Boni's presentation of the excavations. Trained as an architect and experienced in architectural restoration, Boni brought innovative scientific methods to the task of uncovering Rome's archaic past. He did so while deliberately distancing himself from those scholars before him who applied traditional academic approaches, i.e., those reliant on classical literature, to archaeological practice. In large part, Burton-Brown's handbook echoes the descriptions and analyses of Boni's finds in the Roman Forum. However, a closer reading of her text reveals that her personal experiences shaped some of her explanations of the archaeological past in ways that differed from Boni's. In addition, their respective nationalities, British versus Italian, shade how they each value Rome's early history.

Hoards have played a significant role in our narratives of the European Bronze Age, but their purpose and meaning have been the source of much debate. These debates have been positively impacted by studies that investigate the ways in which hoards are connected to specific landscape contexts. In this paper, we discuss the outcome of one such in-depth field study of 62 Bronze Age metalwork deposition locations from the Swedish province of Halland. By systematically analysing digital sources such as museum archives, church records and historical maps, we were able to establish the locations of a number of previously unlocated finds, which were then visited in the field. Through this combined archival work and fieldwork, we distinguished several patterns that allude to a connection between metalwork deposits, object types and specific places in the landscape. These patterns shed light on the landscape context of hoards in this region and illuminate how deposition patterns changed over time; we consider some factors that may help to explain these changes. The results emphasize the importance of landscape studies for understanding the role of selective deposition in European Bronze Age societies, and more broadly, the social implications of hoards in their context.

In this paper, we examine the lunar calendar interpretation to evaluate whether it is a viable explanation for the production of Upper Palaeolithic parietal art. We consider in detail the history of this approach, focusing on recently published variations on this interpretation. We then discuss the scientific method and whether these recent studies are designed to address the research questions necessary to test a lunar calendar hypothesis. More broadly, we explore challenges related to inferring meaning in art of the deep past, the use of secondary sources and selecting appropriate ethnographic analogies. Finally, we assess claims that the lunar calendar interpretation documents the world's oldest (proto)writing system. We conclude that the lunar calendar interpretation as currently construed suffers from multiple theoretical and methodological weaknesses preventing it from being a viable explanation for the production of Upper Palaeolithic art. We further find that claims following from this interpretation to have discovered the oldest known (proto)writing system are unsubstantiated.

Lynchets, often the defining component of historic agricultural landscapes in northern Europe, are generally associated with soft-limestone geologies and are particularly well developed on loess-mantled landscapes. To understand their formation and chronology, the authors present their geoarchaeological analyses of lynchet soils and loess deposits at Blick Mead and Charlton Forest in southern England, and Sint Martens-Voeren in Belgium. The lynchets date from the late prehistoric to the medieval periods and were constructed by plough action at the English sites, and by both cut-and-fill and ploughing in Belgium. This has resulted in the preservation of highly fertile loessic soils across chalk slopes, lost elsewhere. Although each example is associated with local/regional agricultural histories, the lynchets’ effective soil-retention capacities allowed them to survive as important heritage features with environmental benefits over millennia.

Web scraping, the practice of automating the collection of data from websites, is a key part of how the internet functions, and it is an increasingly important part of the research tool kit for scientists, cultural resources professionals, and journalists. There are few resources intended to train archaeologists in how to develop web scrapers. Perhaps more importantly, there are also few resources that outline the normative, ethical, and legal frameworks within which scraping of archaeological data is situated. This article is intended to introduce archaeologists to web scraping as a research method, as well as to outline the norms concerning scraping that have evolved since the 1990s, and the current state of US legal frameworks that touch on the practice. These norms and legal frameworks continue to evolve, representing an opportunity for archaeologists to become more involved in how scraping is practiced and how it should be regulated in the future.

Archaeogaming is an area of increasing interest within archaeology. As archaeogaming's theory and practice are being fleshed out, it is worth considering if there are parallels to traditional archaeological methods within the study of video games. Here, we examine one such possibility: is there an archaeogaming equivalent to experimental archaeology? As a case study, we explore the system used for the mid-1980s development of an unreleased video game prototype for the game company Activision. Through examining this development system, whose use would be otherwise invisible in the finished software artifact, we demonstrate how we have both reconstructed a seemingly lost piece of the system virtually and used this reconstruction for experiments. The methodology we describe can be applied to digital artifacts within contemporary archaeology beyond the scope of video games, and it illustrates some key differences between studying physical and digital artifacts.

With its promise of nondestructive processing, rapid low-cost sampling, and portability to any field site or museum in the world, portable X-ray fluorescence (pXRF) spectrometry is rapidly becoming a standard piece of equipment for archaeologists. Even though the use of pXRF is becoming standard, the publication of pXRF analytical methods and the resulting data remains widely variable. Despite validation studies that demonstrate the importance of sample preparation, data collection settings, and data processing, there remains no standard for how to report pXRF results. In this article, we address the need for best practices in publishing pXRF analyses. We outline information that should be published alongside interpretive results in any archaeological application of pXRF. By publishing this basic information, archaeologists will increase the transparency and replicability of their analyses on an inter-analyst/inter-analyzer basis and provide clarity for journal editors and peer reviewers on publications and grant proposals for studies that use pXRF. The use of these best practices will result in better science in the burgeoning use of pXRF in archaeology.
