Plato and the Theodosian Code

The codification project initiated in 429 ad that resulted in the Theodosian Code was originally designed to integrate three types of law: one, imperial constitutions since Constantine; two, the legal material collected in the tetrarchic Codices Gregorianus and Hermogenianus; and three, a florilegium of juristic writings and responsa. The ultimate aim was to condense all this in a single comprehensive law book that would govern the entire life of the empire and its subjects. As this paper shows, such a project had no precedent in Roman legal history and in fact ran counter to the traditional multiplicity of legal sources in Rome. This prompts a question: from where did the intellectual fathers of the codification project drew inspiration for such a revolutionary idea? In the paper's second part, I argue that one important model for the codification project of 429 could have been the legal code Plato designed for the ideal state of the Laws.     

Estimation of Spatio-Temporal Correlations of Prehistoric Population and Vegetation in North America

We discuss a simple methodology to enable a statistical comparison of human population with the vegetation of North America over the past 13,000 years. Nonparametric kernel methods are applied for temporal and spatial smoothing of point data obtained from the Neotoma Paleoecology Database and the Canadian Archaeological Radiocarbon Database, which results in sequences of maps showing the development of population and different plant taxa during the Holocene. The estimation of smooth spatial and spatio-temporal cross-correlation functions is proposed in order to detect relationships between population and vegetation in fixed time intervals. Furthermore, the effects of varying environment on demographic changes as well as potential impacts of populations on plant taxa over time are analyzed. Pointwise confidence bands for cross-correlation functions are computed and a robustness analysis is performed to assess the significance of obtained results. Considering the example of oak, an interpretation of our results for eastern North America shows the value of this methodology.     

792 or 793? Charlemagne’s canal project: craft,nature and memory

In autumn 793, Charlemagne visited the fossatum magnum (the ‘big ditch’ or canal) between the Rhine and Danube. Excavations, dendrochronology and a re‐reading of Carolingian Annals shed new light on the chronology and setting of this canal, which was planned in 792, initiated in 793, and abandoned later that year. The abandonment is attested by both written and archaeological evidence. The different versions of the annals offer a unique opportunity for comparison with the archaeological record. Evidence that works of Vitruvius circulated in the Carolingian court suggests that Charlemagne’s advisers were drawing on classical tradition when they pitched the idea of digging the canal.     

Coloured Cabinets: A Reflection on Material Culture as a Marker of Coloured Identity in Cloetesville,South Africa

In coloured neighbourhoods of the Western Cape in South Africa, there are objects in people's homes that live in a unique historical and cultural moment. This article reports on an examination, in the neighbourhood of Cloetesville, Stellenbosch, of how these objects inside residents’ homes tell a story of a creolised people and the locations in which they are situated. In the case of Cloetesville, as in many neighbourhoods that arose from a history of forced removals, many people experience various social and economic problems. Coloured people's identities are commonly thought to rest in these problems. This article, however, seeks to suggest an alternative way of exploring coloured identity through looking at objects in households and broader living environments. Thus, I hope to provide insight into different yet distinct experiences by contributing new perspectives through looking at nostalgic and ordentlike (respectable) sentiments of belonging. Specifically cabinets in living rooms are conceptualised as repositories of such sentiments in the home, and how the objects residing in the home have the power/ability to symbolically ground their owners in the neighbourhood of Cloetesville.     

Formation of Fluid Inclusions during Heat Treatment of Barremo‐Bedoulian Flint: Archaeometric Implications

At the end of the fifth millennium bc , the development of a specialized lithic industry in the Chassey societies of south‐eastern France and its dissemination as far as Catalonia and Tuscany attest to important socio‐economic changes in the Mediterranean Neolithic societies. The lithic production was made on barremo‐bedoulian flint that was heat‐treated to improve the sharpness of the tools produced. Microscopic observations of archaeological and geological, heated and unheated barremo‐bedoulian flint samples allowed us to highlight the heat‐induced formation of fluid inclusions. Microthermometry analyses showed that these inclusions contain pure H₂O, most probably resulting from the dehydration of length‐slow (LS) chalcedony and the closure of narrow pores, according to the model proposed by Schmidt et al. ( 2012 ). Our results enable us to estimate the heating temperatures used by Chassey artisans to ≈ 230°C. We also propose the ‘pressure cooker’ model to explain the migration of liquid water in flint nodules heated to 230°C. Then, we discuss the ability of a particular type of flint to be heat‐treated, and hence its value for Neolithic society, which depends on: (1) the amount of LS chalcedony that ensures the water release at relatively low temperature; and (2) on the total volume of porosity available to store the dehydration water.     

Well preserved non‐collagenous extracellular matrix proteins in ancient human bone and teeth

Ancient bones in a good preservation state, ascertained by microscopic techniques, conserve extracellular matrix proteins over thousands of years. With new techniques, intact extracellular matrix proteins from ancient bones and teeth are extracted and separated by one‐dimensional and two‐dimensional electrophoresis. Proteins were identified in Western blots by special antibodies against different human extracellular matrix (ECM) molecules of bone. We have confirmed different types of ECM human bone molecules such as osteonectin, osteopontin, and alkaline phosphatase with specific antibodies in human bone samples from different age groups. Additionally, we selected bone samples from different cultural time periods, such as the Middle Ages, the Bronze Age and the Late Pre‐Pottery Neolithic Phase (PPNB), and teeth from individuals from the Early Middle Ages and from the Late PPNB. The survival of intact extracellular matrix proteins in ancient bones and teeth dating from recent times to the Late PPNB, and reliable techniques to identify these proteins, present a great challenge to further research. A Match Set with PD‐Quest 7.2 shows that only 16% of protein spots in the teeth are also found in the bone of the same individual. In combination with the results of macro‐ and microscopic investigation, biochemical techniques will help us in obtaining a better understanding of bone and teeth in health and disease.
