The Enigma of the Great Thapsus Harbour Mole

On the East coast of Tunisia, between Sousse and Sfax, lie the scant remains of the ancient city of Thapsus, notable mainly for a battle fought in the civil war in 46 BC. Visits by the authors resulted in the discovery of one of the longest‐known harbour moles in the entire Roman Empire. No ancient sources make reference to any work of such magnitude and the paper suggests that the harbour was never completed, but might have been started by the local emperors Gordianus, none of whom survived long enough to have executed such a project.     

Colonialism,Dining, and Changing Strategies of Power: the Example of Iron Age and Roman Mediterranean France at Lattara (ca 150 bc–ad 50)

The establishment of colonial rule by one society over another, both in ancient and modern examples, often has dramatic consequences for the establishment and maintenance of political relationships within the context of everyday life in colonial society. In this article, I examine the ways in which the performative acts of dining can play an integral role in this reconstruction of political relationships that is so often implicit in colonial encounters and state expansion. In particular, I suggest that an analysis of the ceramic evidence of vessels used in dining and the frequency of specific forms in the overall assemblages can help to reveal the ways in which the politics of commensality play an active role in transforming political relationships and strategies of power in colonial societies. This article uses the example of ancient Mediterranean France after the Roman conquest in the late second century bc at the Celtic-speaking settlement of Lattara (modern Lattes). I argue that by the end of the first century bc, coinciding with a time period when the political structure of the region was being significantly reorganized, there was a notable change in dining practices, with a move away from a more communal ethos in dining to one emphasizing the individual. These new practices served the strategic interests of individuals in local society at Lattara seeking to break with earlier political systems and integrate themselves into larger colonial society.     

Failed Eastern integration and a partly successful opening up to the West: the economic re-orientation of Hungary during the 1970s

The article investigates the ‘long 1970s’ (1968–82), when Hungary re-orientated its economic and foreign-trade relations. Hungary was always a promoter of a deepening of Council for Mutual Economic Assistance (CMEA) co-operation and when it noticed that socialist integration stagnated at the level of the bilateral exchange of commodities, Budapest gradually launched a policy of opening up to the world outside the CMEA. The year 1977 was a turning point in economic policy. Hungarian elites' thought and attitude towards the West changed, but not independently of the world economic crisis and its impact on Hungary. The oil crisis sharpened latent tensions, and behind the robust growth serious problems appeared. Although Hungary intensified its interrelations with the West and the Third World, the country was not able to profit from the advantages of international trade and co-operation. The article is based on state, party and senior economic leaders' archives.     

Hydrothermal,multiphase convection of H2O‐NaCl fluids from ambient to magmatic temperatures: a new numerical scheme and benchmarks for code comparison

Thermohaline convection of subsurface fluids strongly influences heat and mass fluxes within the Earth's crust. The most effective hydrothermal systems develop in the vicinity of magmatic activity and can be important for geothermal energy production and ore formation. As most parts of these systems are inaccessible to direct observations, numerical simulations are necessary to understand and characterize fluid flow. Here, we present a new numerical scheme for thermohaline convection based on the control volume finite element method (CVFEM), allowing for unstructured meshes, the representation of sharp thermal and solute fronts in advection‐dominated systems and phase separation of variably miscible, compressible fluids. The model is an implementation of the Complex Systems Modelling Platform CSMP++ and includes an accurate thermodynamic representation of strongly nonlinear fluid properties of salt water for magmatic‐hydrothermal conditions (up to 1000°C, 500 MPa and 100 wt% NaCl). The method ensures that all fluid properties are taken as calculated on the respective node using a fully upstream‐weighted approach, which greatly increases the stability of the numerical scheme. We compare results from our model with two well‐established codes, HYDROTHERM and TOUGH2, by conducting benchmarks of different complexity and find good to excellent agreement in the temporal and spatial evolution of the hydrothermal systems. In a simulation with high‐temperature, high‐salinity conditions currently outside of the range of both HYDROTHERM and TOUGH2, we show the significance of the formation of a solid halite phase, which introduces heterogeneity. Results suggest that salt added by magmatic degassing is not easily vented or accommodated within the crust and can result in dynamic, complex hydrologies.     

Mapping social relationships: geophysical survey of a nineteenth-century American slave cemetery

The goal of this project is to identify unmarked burials inside the known limits of a historic cemetery and unmarked slave burials adjacent to the cemetery to answer questions regarding variability in treatment of slaves by slave owners. This project used three geophysical prospection methods (electromagnetic induction/conductivity, ground penetrating radar, and magnetic susceptibility) to image the subsurface and locate unmarked graves. The results indicate that up to 21 possible unmarked graves exist at the Prior Cemetery. The survey detected 17 with two or more geophysical techniques and four with a single technique. Nine possible unmarked graves were tested with a metal probe. Every tested anomaly revealed less compact soils indicative of an unmarked grave.     

The technology Of the yamnaya (pit grave) ceramic production And its relevance to the population history Of the volga-ural region in the early bronze age

Based on ceramic assemblages from the Yamnaya (Pit Grave) culture burials, the technology of pottery manufacture practiced by the Early Bronze Age people of the Middle Volga–Southern Ural region is described. The analysis follows the methodology developed by A.A. Bobrinsky. The results are used for reconstructing the origin and evolution of the Pit Grave culture. The role of ceramics in Early Bronze Age funerary ritualism is discussed.     

MINERALOGY OF BOHEMIAN GREEN EARTH PIGMENT AND ITS MICROANALYTICAL EVIDENCE IN HISTORICAL PAINTINGS

While the most famous historical green earth deposits in Italy and Cyprus were exceptionally rich in celadonite, the deposits near Kadaň, Czech Republic, consisted of thin Fe‐rich celadonite impregnations accompanied by interstratified celadonite/smectite. In superimposed tuffs, smectites become prevalent and their colour changes from forest to olive green. Powder X‐ray microdiffraction and infrared microspectroscopy permit us to distinguish between green earth minerals in microsamples taken from works of art. The Ti contents and the Fe/Mg ratios help to indicate the presence of Bohemian green earth from Kadaň. We found this material in local 18th‐century works of art and also in paintings by Anton Kern (1709–47).     

TRANSPORT AND SUBSISTENCE PATTERNS AT THE TRANSITION TO PASTORALISM,KOOBI FORA,KENYA

The Turkana Basin in Kenya has an extensive record of Holocene activities relating to mobility and economy of foraging and herding communities. Obsidian is only known from a few key localities in northern Kenya. As such, the use of obsidian as a toolstone material, commonly used during the mid‐Holocene, provides one way to trace exchange, interaction and population movements during the transition to pastoralism. We employ X‐ray fluorescence to characterize obsidian artefacts from four Pastoral Neolithic assemblages. Data reveal a highly mobile and diversified population that used watercraft to access and transport obsidian resources. Specifically, the use of the North Island obsidian source in Lake Turkana indicates that boat use was significant during this transitional period. The incorporation of watercraft transport and aquatic resources in our analyses of Pastoral Neolithic sites affords a greater understanding of subsistence, mobility and economy in this important period in East African prehistory.
