Pro tutela regni: revisiting a royal diploma from 918 on the birth of Normandy and the first ‘ducal’ laws

The Treaty of Saint‐Clair‐sur‐Epte (911) and the cession of Normandy to Rollo have long been considered as evidence of a decline in Carolingian power during the reign of Charles III the Simple. If, during the twentieth century, this view has undergone gradual revision, the role that the king could have played in the process of the Normans’ installation on the Seine remains obscure. A review of the relevant royal diplomas, in particular that of 14 March 918, suggests, however, active participation by the king in the emergence of a Norman march in Neustria: that is to say, a political and legal programme intended to reaffirm royal authority over this part of the regnum Francorum. This rereading, based on Frankish texts, on Christian ideology and on the Roman heritage, suggests a new interpretation of the settlement of Scandinavians in Normandy, the emergence of a Norman principality, and the genesis of the famous ‘laws of Rollo’.     

Towards a three-dimensional cost-effective registration of the archaeological heritage

Archaeological practice within the European context of heritage management is facing huge challenges in ways of recording and reproduction of ex-situ preserved sites. As a consequence of the Valletta-treaty, numbers of archived images and drawings of excavated structures as prime sources of past human activity, are exponentially growing. Contrarily to portable remains however, their future study and revision is biased by the two-dimensional character of the recorded data, rendering difficult their future reconstruction for new study or public dissemination. A more realistic three-dimensional (3D) way of recording and archiving should be pursued. In this paper the possibilities for 3D registration of archaeological features are examined in a computer vision-based approach using the PhotoScan software package (Agisoft LCC). It proved to be a scientific and cost-effective improvement compared to traditional documentation methods. Advantages can be found in the high accuracy and straightforwardness of the methodology. The extraction of an orthophoto or a Digital Terrain Model from the 3D model makes it feasible to integrate detailed and accurate information into the digital archaeological excavation plan. The visual character of 3D surface modeling offers enhanced output-possibilities allowing a better documentation of in-situ structures for future research and a higher public participation and awareness for the archaeological heritage.     

Evidence of early medieval soda ash glass in the archaeological site of San Genesio (Tuscany)

The early medieval period marks an important turning point in the history of glassmaking, since it comprises the transition period between the mineral-based silica-soda-lime glass of the Roman tradition and the plant ash-based glass. With the aim of expanding the knowledge on the glass recipes and technologies of this period, 37 glass samples were analyzed, originating from the archaeological excavations of San Genesio (Tuscany) and dated from the fourth to the eleventh century. The major and minor element concentrations were measured with SEM-EDX, while the trace elements were quantified with LA-ICP-MS. The results were compared with published compositions of glass samples of similar age in order to highlight differences and similarities. The results offer a very interesting view on the glass circulation in the religious/residential/manufacturing center of San Genesio in the early medieval period. Most of the glass has a typical late-Roman composition, but some glass fragments are identified as soda ash glass. These are among the earliest medieval ash-fluxed glasses ever found in the Italian peninsula.     

Optical spectroscopy as a rapid and low-cost tool for the first-line analysis of glass artefacts: a step-by-step plan for Roman green glass

Archaeometric research on glass artefacts is continuously evolving and is converging towards a multidisciplinary research domain where different types of techniques are applied depending on the questions asked and the circumstances involved. The technique described in this work is optical spectroscopy. The benefit of this technique being the possibility of building up a knowledge database for a large amount of material in a relatively short period of time and with a relatively limited budget. This is of particular interest for the investigation of extensive and/or unexplored glass collections where a first-line analysis of artefacts could facilitate the selection of material needing further and more detailed examination.     

Miniature dissonance and the museum space: reconsidering communication through miniaturisation

Miniature objects from non-European contexts have ideological elements which are often overlooked in the museum space because their small size and iconic relations make them difficult to accurately interpret and disrupt curatorial efforts to impose meaning upon them; a situation I term miniature dissonance. This article will examine this phenomenon using three related case studies featuring miniatures from the Northwest Coast of North America. It will consider what might have been misunderstood in these objects and what they might originally have been intended to achieve, followed by an example from a recent Ancient Egyptian exhibition which demonstrates that this problem is both more widespread and problematic than is often recognised. These miniatures disrupt curatorial intentionality in the museum space, and it is only by carefully considering their origins and affordances that they can be adequately and accurately interpreted and displayed.     

Study of medieval glass fragments from Savona (Italy) and their relation with the glass produced in Altare

Altare was in the medieval and post-medieval period an important glassmaking center in the Liguria region in Northern Italy. The first historical evidence of glassmaking in Altare is dated to the twelfth century. In spite of that, due to the continuity of glassmaking up to the present time and the contemporaneous intensive urbanization of the territory, no medieval glass from Altare or its immediate vicinity has been analyzed up to now. In this work, glass from archaeological excavations in the center of Savona, city with close ties with the glassmaking center, was studied. Glass fragments, dated from the tenth to the sixteenth century were selected from the collections of the Archaeological Museum in Savona and non-destructively analyzed with quantitative PIXE-PIGE. The resulting compositions, compared with known glass productions of the same time and evaluated on the basis of historical documents, offer an interesting panorama on the variety of glass circulation in Liguria.     

The Olympic legacy: Feeding London (Respond to this article at http://www.therai.org.uk/at/debate)

Over the last decades, the Olympic Games have increasingly claimed to deliver a social and economic ‘legacy’ to the host city. The 2012 Olympic Games in London have set out to deliver a legacy of better food for east London, an area perceived as ‘deprived’, with higher than average rates of obesity and significant ‘food deserts’ in its midst. Various Olympic organizations have considered the issue, resulting in the publication of a Food vision for the first time ever in Olympic history. However, with companies such as Coca‐Cola and McDonald's having been appointed official suppliers to the Games, and with an extremely limited time frame, will the Games be able to deliver on this promise?     

Raw materials for medieval to post-medieval Tuscan glassmaking: new insight from LA-ICP-MS analyses

LA-ICP-MS analyses were performed on a set of Tuscan (post) medieval archaeological glass finds dated to the 13–16th century in order to quantitatively determine the trace element contents. The results are used for defining and distinguishing several compositional groups. The trace element data are consistent with the distinctions obtained by considering the major element data determined via quantitative SEM-EDX, but allow to obtain new insights into the nature and quality of the silica sources employed and the presumed method of ash purification.
