A hoard of Nilotic nacreous shells from Egypt to Jericho (Early Bronze II, 3000–2800 BCE): Their finding,content and historical archaeological implications

ABSTRACT

The Tell es-Sultan, ancient Jericho, is amongst the earliest “cities” that rose in the Southern Levant between the end of 4th and the beginning of the 3rd millennium BCE. The site is being excavated, studied and rehabilitated for tourism by Sapienza University of Rome and the Palestinian Ministry of Tourism and Antiquities since 1997. In 2017, during the 13th season of excavation, an unexpected discovery occurred: five Chambardia rubens shells have been found piled up in a dwelling unit dating back to the Early Bronze Age IB-II. The discovery is a tangible evidence of trade and cultural interconnections between the Southern Levant and Egypt, as these shells belong to a species that is only been found to live in the Nile. Moreover, chemical analysis, and thorough Scanning Electron Microscopy examination revealed that the shells contained Manganese Dioxide, an inorganic compound used as make-up ingredient in ancient Egypt, and available in the ores of the Sinai. These findings strongly support the existence of a link between the urban rise in EB IB-II through international trade of luxury goods, and are suggestive of the emergence at Jericho of a ruling elite that was influenced by Egypt.     

Higher education institutions,economic growth and GDP per capita in European Union countries

This paper presents an estimation of the contribution of Higher Education Institutions (HEIs) to economic growth and the Gross Domestic Product per capita of the European (EU) countries over the period 2000–2015. For this purpose, we analyse the universities’ effects on the supply side of their national economies, especially the contribution of the R&D of HEIs to technological capital of the European (EU) countries. We proposed a methodology of counterfactual scenarios, which assume a hypothetical situation in which HEIs do not exist, to estimating the effects of HEIs, applying techniques of growth accounting. The results obtained indicate that these effects are a significant source of growth in European (EU) countries, contributing to mitigating the adverse effects of the periods of crisis. The estimates show that GDP per capita would currently be more than 11% higher than that corresponding to a scenario without HEIs. The results obtained also show significate differences in GDP per capita between European (EU) countries associated with the activity of HEIs.     

A disobedient gaze: strategic interventions in the knowledge(s) of maritime borders

Abstract

This article reflects critically on how forms of militant research that produce knowledge about the border can produce effects in the politics of migration themselves. It does so by looking at Forensic Oceanography, a collaborative research project that we have been conducting since the summer of 2011. We first locate this research among a broader ‘ecology of knowledges’ that are generated at the border and that directly affect way the border regime actually operates, underlining their ‘aesthetic’ dimension. Secondly, we problematise more specifically the knowledge produced by activists who fight against the border regime and attempt to think how these need to position themselves strategically in relation to existing knowledge practices so as to avoid complicity with the same power structures they are seeking to challenge. Finally, since our knowledge production has amongst others been geared towards the legal sphere, we sketch out a critical reflection on the reliance on legal strategy to forward progressive changes within the politics of migration.     

Underwater Investigation on a Marble Cargo Wreck at Capo Bianco near Isola di Capo Rizzuto,Crotone, Italy

The cargo of marble blocks off Capo Bianco was dated to the Roman period. New sampling and analysis has identified Carrara marble, and also Rosso di Francia and Portargento, which strongly suggests a post‐medieval date. This leads to the suggestion that nearby finds dating between the second half of the 18th century and the first half of the 19th may come from the same ship, perhaps sailing from France and Liguria to deliver stone in southern Italy. This is rare evidence of the post‐medieval marble trade and demonstrates the importance of archaeometric analysis for the interpretation of wrecked cargos. © 2011 The Authors     

Protocol for lapis lazuli provenance determination: evidence for an Afghan origin of the stones used for ancient carved artefacts kept at the Egyptian Museum of Florence (Italy)

Despite that the Badakhshan Province (Afghanistan) remains the most plausible hypothesis for the lapis lazuli used in antiquity, alternatives proposed in literature are worth to study to confirm or disprove their historical reliability. In this work, a protocol for determining the provenance of lapis lazuli rocks used for carved artefacts is described. Markers for the univocal attribution of the raw material to a source were identified analysing 45 rocks of known provenance (among which 15 georeferenced) from 4 quarry districts. To the best of our knowledge, this reference database is the widest in provenance studies on lapis lazuli. All the markers are recognisable by means of Ion Beam Analysis (IBA) techniques, in particular micro-proton-induced x-ray emission (PIXE) and micro-ionoluminescence (IL). These techniques are non-invasive and applicable in air, allowing to analyse artworks and rocks of practically any shape and dimension without sample preparation.The protocol was applied to determine the provenance of raw material used for carved lapis lazuli artefacts kept at the Egyptian Museum of Florence, the second most important Egyptian museum in Italy, second only to the museum of Turin. The collection in Florence has a great historical value and includes several lapis lazuli pendants, scarabs, small statuettes and amulets ascribable mainly to the first millennium BC. Following the protocol, 11 of these artefacts were analysed by means of IBA techniques. Results ascribe the raw material to the Afghan quarry district.
