Representative archaeological finds of <Emphasis Type="Italic">pietra ollare</Emphasis> from Comacchio (Italy): identifying provenance and high-T mineral breakdown reactions hindering lithotype classification

Three different lithotype groups have been recognized in representative fragments of pietra ollare artefacts found in the mediaeval archaeological excavations of Comacchio (Italy). Petrographic, mineralogical and chemical compositions clearly show that Valchiavenna and Valmalenco, in the Central Alps, represent the provenance areas of two of the pietra ollare groups, i.e. grey carbonate talc schist (also known as soapstone) and green chlorite schist, respectively. The third representative pietra ollare group consists of whitish-yellowish rocks inferred to be Alpine talc schists that have suffered some artificial pyrometamorphic transformation hindering their classification in the framework of pietra ollare lithotype categories and source localities reported in literature. A distinguishing feature of these high temperature-fired (HT-fired) talc schist samples is the occurrence of talc and chlorite dehydroxylation and subsolidus reaction products, mainly protoenstatite/enstatite + forsterite, together with relatively low loss on ignition values. These talc schists might have been exposed to temperatures >900 °C (with the resulting talc dehydroxylation producing a void-rich texture), but never reaching 1200 °C, which is the sintering temperature for soapstones. The whitish-yellowish artefacts were definitely not used as containers for cooking food at temperatures below or around 500–600 °C (as instead shown by the preservation of the original physical features of the grey pietra ollare lithotypes), but in some kind of higher-T pyrotechnological processes.     

A spotted hyaena den in the Middle Palaeolithic of Grotta Paglicci (Gargano promontory,Apulia, Southern Italy)

The Palaeolithic sequence of Grotta Paglicci (Gargano promontory, Apulia, Southern Italy) is one of the most important in the Mediterranean area: It comprises the whole Upper Palaeolithic cultural sequence known for the region, as well as Early Middle Palaeolithic and Lower Palaeolithic levels. These earlier phases are best represented in a collapsed room located outside the present-day cave (the so called “external rock shelter”). In this area, a new excavation, started in 2004, brought to light Middle Palaeolithic animal remains associated with evidence of spotted hyaena (SU 64 and 53). The spatial distribution analysis of remains from SU 53 revealed the presence of a bone accumulation area and a wider dispersal of hyaena coprolites. Three main ungulate species (aurochs, fallow deer and red deer) as well as carnivores (spotted hyaena, wolf, fox, wild cat and lynx) and lagomorphs have been identified. The majority of aurochs remains are located in the main accumulation; among these specimens, a complete metatarsal connected with three tarsal bones has been found; a talus and a complete tibia, probably belonging to the same limb, have also been identified. The multidisciplinary study carried out in this paper highlights a specific bone accumulation and scattering pattern in a spotted hyaena (Crocuta crocuta) den. In addition, taphonomy of lagomorph remains indicates the presence of other depositional agents.     

The Marausa Wreck,Sicily: interim report on a boat built in the Western Imperial Roman tradition

In 1991, the wreck of a late 3rd–early 4th century AD Roman merchant vessel was discovered on the west coast of Sicily that had carried North African amphora, tubuli, and other ceramics. The hull was dismantled and raised in 2011, including a keel hook‐scarfed to stem and sternposts, 39 pegged mortise‐and‐tenon joined planks, 43 frames with an irregular pattern of floor‐timbers, half‐timbers, and futtocks fastened to the planking with treenails and copper nails, sister‐keelsons and evidence of two stringers, 36 ceiling strakes, and the base of a bilge pump. Many repairs are indicated. The fairly flat bottom and round bilges, mortise‐and‐tenons, sister‐keelsons and lack of a coherent framing pattern, place the boat in the Western Imperial tradition.     

Unwritten Factors Affecting Structural Funds: The Influence of Regional Political Behaviours on the Implementation of EU Cohesion Policy

While EU regional policy has the ambitious objective of supporting lagging regions and promoting inter-regional convergence, its impact is dependent on the ability of regional policymakers to secure and use EU funding to meet the region's needs. This paper aims to show under which conditions politics has a defining influence on the distribution, allocation and utilization of structural funds (SF), specifically in Objective 1 regions. The empirical analysis focuses on the 2000–2006 programming cycle in France, Germany, Italy, Spain and the UK. The results show that regions politically aligned with national governing coalitions tend to perform better in terms of received SF support and enjoy more flexibility in implementing SF. However, the influence of regional political behaviours on economic performances is very limited. The findings confirm the importance of politics in influencing SF implementation, but its limited influence on economic outcomes.     

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.     

New Excavations at Border Cave,KwaZulu-Natal,South Africa

New excavations at Border Cave use high-resolution techniques, including FT-IR, for sediment samples and thin sections of micromorphology blocks from stratigraphy. These show that sediments have different moisture regimes, both spatially and chronologically. The site preserves desiccated grass bedding in multiple layers and they, along with seeds, rhizomes, and charcoal, provide a profile of palaeo-vegetation through time. A bushveld vegetation community is implied before 100,000 years ago. The density of lithics varies considerably through time, with high frequencies occurring before 100,000 years ago where a putative MSA 1/Pietersburg Industry was recovered. The highest percentage frequencies of blades and blade fragments were found here. In Members 1 BS and 1 WA, called Early Later Stone Age by Beaumont, we recovered large flakes from multifacial cores. Local rhyolite was the most common rock used for making stone tools, but siliceous minerals were popular in the upper members.     

Performance-based Seismic Risk Assessment of Urban Systems

ABSTRACT

Disaster risk mitigation has become a urgent global need. Similar to other natural hazards, earthquakes may cause significant damage on a large scale. In Europe and in other regions with dense urbanization, seismic events can heavily impact historical city centers due to the several structural fragilities. These centers are often part of the worldwide cultural heritage and their preservation is considered a strategic issue. Furthermore, earthquakes may have severe negative short-term economic effects on the impacted communities and adverse longer-term consequences for economic growth. For this reason, the development of an efficient approach for urban seismic risk assessment becomes essential. An original approach is proposed, based on performance concepts and multidisciplinary perspectives. The procedure is applied for validation to the city center of Concordia Sulla Secchia (Italy), damaged by the 2012 Pianura Padana Earthquake (PPE), comparing predicted damage scenarios with the actual post-seismic survey data.     

Morphological reconstruction of Roman <Emphasis Type="Italic">styli</Emphasis> from <Emphasis Type="Italic">Iulia Concordia</Emphasis>—Italy

Iulia Concordia is an important Roman settlement known for the production of iron objects and weapons during the Roman Empire. A huge number of well-preserved styli were found in the bed of the main channel of the city. In order to shed light on the production processes used by Roman for stylus manufacturing and the conservation state of the finds, a neutron tomography analysis was performed on NEUTRA beamline in Switzerland. SEM-EDS analyses were performed on few selected objects in order to identify the composition of metal decorations. Here, we present results from our investigation conducted on 91 styli, disclosing, in a non-invasive way, the morphological characterization related to the ancient Roman working techniques.     

Combining residue analysis of floors and ceramics for the study of activity areas at the Garum Shop at Pompeii

In this paper, we propose the application—for the first time in the Mediterranean area—of the combination of the study of chemical residues in floors and ceramics, with the aim of providing information about the activities carried out in archeological buildings. We chose the Garum Shop at Pompeii to test the method. In fact, due to the peculiarity of this archeological context, it provided an ideal case in which the activities performed are in part known, and the ceramic vessels recovered are still in situ. Floor samples were studied by means of spot tests developed in Mexico aimed at identifying the presence of phosphates, fatty acids, and protein residues, while the organic residues preserved in the ceramic matrix of amphorae, dolia, and other ceramic vessels were studied by gas chromatography coupled with mass spectrometry. Moreover, we integrated the data obtained with specific studies directed at better identifying the solid residues found inside two of the amphorae studied: botanical studies of fruit stones recovered in a Dressel 20 amphora and the characterization of the lime preserved in an African amphora. The research allowed for the identification of the traces of some of the activities performed, such as cooking and producing garum in the floors of the building, and the use and re-use of amphorae and dolia before the Vesuvian eruption.     

Georadar investigations in the central nave of Hagia Sofia,Istanbul (Turkey)

Within an interdisciplinary project to study Istanbul’s Hagia Sofia, a georadar survey was carried out in the central nave to assess if the deformations of the structure previously observed could be related to a differential behavior of the subsoil caused by architectural remains underneath. This study faces an unusual challenge since it was necessary to study the space beneath the scaffolding placed for the restoration works. The survey of the central nave was successful and allowed the detection of remains of walls that probably formed the basement of a previous 18- by 22-m structure. In addition, another interesting feature was discovered 2 m below the marble mosaic in the southeastern part of the nave. Although it is not possible to define its function, it seems that there could be a close relationship between this 2- by 3-m buried structure and the marble mosaic in the floor surface. Although some structures were identified under the floor of Hagia Sofia, there are no major changes in the topography of the central nave floor.
