THE MELTING FURNACE OF THE DERRIÈRE SAIROCHE GLASSWORKS (COURT,SWISS JURA): HEAT‐INDUCED MINERALOGICAL TRANSFORMATIONS AND THEIR TECHNOLOGICAL SIGNIFICANCE*

Seventy‐one oriented specimens from the pre‐industrial reverberatory melting furnace of the Derrière Sairoche glassworks (Swiss Jura) were analysed. During its period of activity (1699–1714), this glassworks produced wood‐ash glass of liquidus temperatures up to 1400°C. Textural and mineralogical features point to temperatures around 1500°C in the melting chamber. The inner structure of the furnace shows chemical contamination due to ash, molten glass and furnace gases. These results reveal the pyrotechnological know‐how of the glassmakers and prove that the thermal performance of this kind of furnace has been under‐evaluated in the past.     

Beads from a mediaeval pilgrim centre: Chemical composition and provenance of glass from Banganarti,Nubia, Sudan

Christian Nubia was a region with intensive transcultural connections that are visible through the understudied overseas glass bead imports found there. This paper presents the results of an analysis of 20 glass beads from Banganarti, a Christian pilgrim site active during the Makuria kingdom (mid-sixth to 14th centuries CE). Compositional analyses using laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) have identified glass belonging to a number of broad compositional groups. Two beads were made of mineral soda-lime glass, dated before the mid-ninth century CE. Numerous beads were made from plant ash-soda-lime glass associated with “Mesopotamian” production dated between the eighth and 10th centuries CE. Lead-soda-silica glass has parallels in the ninth–10th centuries glass found in Africa and Europe. One plant ash-soda-lime bead was of eastern Mediterranean origin dated after the 10th century CE. Results of this study provide new evidence for provenance and chronology of glass beads available in the mediaeval Northeast Africa as well as contribute new data to the research on the pilgrim and/or trade routes of that time.     

Who were the Meroites? A biological investigation into the Nubian post‐hiatus group

Scholars have identified a hiatus in the archaeological record of Lower Nubia that spans approximately 1000 years. This interval may represent a desertion of Lower Nubia by its inhabitants. Evidence of occupation did not reappear in the area until the Meroitic time period. However, the identity of the returning people has been the subject of speculation. In order to determine who the Meroites of Lower Nubia were, 20 cranial non‐metric traits were observed on six Nubian groups, representing five time periods. Two groups date to time periods immediately before (Kerma) and immediately after (X‐Group) the Meroitic period. Three additional Nubian groups (two Christian samples from different sites and Sesebi, a contemporary sample) were utilised as outgroups to elucidate a clearer picture of the relationship among the six samples. Mahalanobis D² with a tetrachoric matrix was employed for calculating biological distances among the groups. Principal coordinates analysis produced two clusters of Nubians, where the Meroitics clustered with other Nubian groups. Specific distance scores indicate the Meroites were biologically similar to individuals from the time periods prior to and after their arrival in Lower Nubia. The Meroites therefore appear to be a Nubian group returning to Lower Nubia after its desertion. Copyright © 2009 John Wiley & Sons, Ltd.     

Overseas imports on the Blue Nile: Chemical compositional analysis of glass beads from Soba,Nubia

Archaeological evidence as well as textual sources leave no doubt about Alwa's (Alodia's) intense transcultural connections, further corroborated by understudied overseas glass bead imports found there. This paper presents results of an analysis of 23 glass beads from Soba, the most prosperous capital of medieval Nubia. Compositional analyses using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) have identified glass belonging to a number of broad compositional groups. Three samples were made of soda lime low-alumina glass produced in the Middle East (v-Na-Ca) and Egypt (m/v-Na-Ca). The remaining beads were made of two types of mineral–soda high-alumina glass (m-Na-Al) North Indian in origin. The results of this study provide new evidence for the provenance and chronology of glass beads available in medieval Soba and Northeast Africa, and contribute new data to research on trade contacts of that time.     

Morphometric Assessment of the Appendicular Skeleton in the New Kingdom and Napatan Components from Tombos in Upper Nubia

Due to its critical location on the Nile River controlling trade from the south, Tombos is an important ancient site to explore the interaction between Egyptians and Nubians. To assess population continuity at Tombos through sociopolitical transitions, the appendicular skeleton of people from the New Kingdom and Napatan periods was examined. Using morphometric and statistical analyses, body proportions on the upper and lower limbs were studied on each element through size (i.e. length, breadth, and width) and shape (bone's measurements with size removed). The Napatan component (when Nubia ruled Egypt) was consistently larger in size than the earlier New Kingdom component (when Egypt ruled Nubia), with little variation in shape. More variability in both size and shape was observed in males. When compared with other Nubians (C‐group and Kerma) and Egyptians (Middle and New Kingdom), the Tombos Napatan sample (males and females) was generally larger, whereas the Tombos New Kingdom sample was generally smaller than other Nubians and similar in size to Egyptians. Some of the variability between the Tombos samples may be the result of gene flow, or rather changes in migration to the area through time and sociopolitics. However, the numerous differences in size with few in shape provide more support for an environmental explanation since size is more susceptible to nutritional stress, disease, and physical activity. These results show that the people of Tombos underwent biological alterations during these major sociopolitical changes from Egyptian rule over Nubia during the New Kingdom to Nubia ruling Egypt during the Napatan period. This study also demonstrates that morphometric analyses of multiple bones and measurements are an important supplement to other bioarchaeological analyses to provide a broader of view of physical changes that occur over time.

Glass beads and pendants from Meroitic and Nobadian Lower Nubia,Sudan: Chemical compositional analysis using laser ablation‐inductively coupled plasma‐mass spectrometry

This paper presents a detailed elemental analysis of 64 glass beads and pendants dated to the Meroitic period (first–third centuries ad ) and the Nobadian period (fourth–sixth centuries) from burial sites in the Lower Nubian Nile Valley region. Laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) was used to determine the chemical composition of the glass and to gain knowledge about its origin. Four main glass types were identified: low‐alumina soda‐lime glass, high‐alumina glass, plant‐ash soda‐lime glass, and mixed‐alkali glass. Mineral soda‐lime glass (m‐Na‐Ca) of East Mediterranean/Egyptian provenance is dominant within the low‐alumina glass group from Meroitic and Nobadian periods. Mineral soda high‐alumina glass (m‐Na‐Al) appeared in the Nobadian bead assemblages, and the m‐Na‐Al 1 subtype was produced in Sri Lanka/South India. An initial insight into the origin of the glass beads in Nubia from the first to sixth centuries is described, indicating the first evidence for the presence of Asian objects in Nubia. The data obtained for the bead trade in North‐east Africa in this study has allowed a new light to be shed on the westward flow of Asian glass during a time of intensive maritime trade contacts with the wider Indian Ocean world.     

Archers’ Looses in Iron Age Sudan: An Asiatic Style in an African Context

Abstract

The archer’s loose, used as protection for the thumb while drawing the bow, is traditionally associated with the Asiatic style of archery and regarded as a response to the introduction of the composite bow. Little attention has previously been paid to looses found in ancient Nubia, and this paper presents a more comprehensive typology of this material. It confirms a divergence between purely functional forms and a later ceremonial tradition that existed alongside the functional looses. This ceremonial tradition is discussed as a marker of an elite military identity, demonstrating the cultural impact of conflict.     

Architecture,Power, and Communication: Case Studies from Ancient Nubia

Monumental architectural remains are among the most impressive relics of the ancient civilizations. Of course, this is also true for ancient northeast Africa. In this contribution, monumental architecture is considered not just as a static marker and manifestation of power, often embedding the state itself in the landscape, but as a location, a setting for performing public activities which are producing and replicating social relations. Some case studies of the Kerma and Meroitic cultures of ancient Nubia are discussed. Hypotheses on the ceremonies taking place are proposed.     

Evaluation of treated and un-treated Nubia Sandstone using ultrasonic as a non-destructive technique

Deterioration factors, both “exogenous” and “endogenous”, are major sources of damaging monumental stones in Egypt. In the current study, the change state of one of the major Egyptian stones (Nubia Sandstone) is investigated and evaluated before and after consolidation by the use of wave velocity as a new method for detecting its elasticity modulus. Wave velocity propagation (Vp) is one of the most important and effective methods for estimating the durability of monumental stones without using any other harmful method as a compressive strength. This technique is usually used for a number of purposes, the first of which is the qualification of masonry building through its morphology and detection of internal defects (e.g. voids and cracks). The second is the examination of the changes of material physical properties, and the control conservation procedures. Third, it is used with some samples of Nubia sandstone for a laboratory test. The study concludes that the durability of samples increases due to the increase of material compacting as a direct result of using consolidant materials. Using the Vp as a non-destructive technique in examining monumental materials gives the same results of other harmful techniques.     

MINERALOGICAL ANALYSES OF CERAMIC MATERIALS FROM QUINUA,DEPARTMENT OF AYACUCHO,PERU

Mineralogical analyses of clays, tempers and paints from contemporary sources in the vicinity of Quinua, Peru, were carried out by means of X-ray diffraction, microscopic examination and physical separation. The data indicates that (1) there is a substantial amount of mineralogical variability in these materials, (2) the differences between the clays and tempers consist of the differences between the relative amounts of plastics and non-plastics present in each of these kinds of materials, (3) the paints contain a mineral known for its superior spreading qualities. The study concludes that (1) the region had the ceramic resources to support a tradition of several polychrome styles like those made during the Peruvian Middle Horizon (a.d. 600–800), (2) ancient pastes made in the region had a great deal of mineralogical variability, (3) archaeologists should redefine their notion of ‘temper’, and (4) modern mineralogical differences between pastes tempered by the potter and those not tempered by the potter can also apply to ancient pastes of the region.     

Chemical analyses of the earliest pigment residues from the uttermost part of the planet (Beagle Channel region,Tierra del Fuego,Southern South America)

This paper presents the results of chemical analyses of the organic and inorganic fractions of pigment residues found in three archaeological sites located in the Beagle Channel region, Tierra del Fuego, Southern South America. Twenty-one archaeological samples have been analysed through XRD, SEM–EDX, FT-IR and GC–MS in order to characterise their inorganic colouring components and to search for the presence of organic substances used as binders. Lipids found in some samples are considered as potential binders. These organic components are compared to those found in archaeological sediment samples from the same layers where the pigments have been found, in order to search for potential taphonomic contaminations of the latter by the former. Results show that such contaminations are unlikely, hence the lipid contents are deemed of anthropic origin. The pigment sample results are also compared to data from analyses of natural sediment samples collected in several localities of the Beagle Channel in order to search for potential natural pigment sources. Results show that organic and inorganic components of these sediments are not the same than those present in the archaeological pigment samples, hence the pigment raw material sources have not been yet located. All these data provide for the first time evidence of the existence of ancient activities of pigment sourcing and paint preparation with organic binders which range from 6000 BP to 1900 BP in the southernmost region of the planet.     

The Mw 6.4 SW-Achaia (Western Greece) Earthquake of 8 June 2008: Seismological,Field, GPS Observations,and Stress Modeling

On June 8, 2008 a Mw = 6.4 earthquake occurred in NW Peloponnese, western Greece. This event is the largest strike-slip earthquake to occur in western Greece during the past 25 years. No surface rupture was observed. Many rock falls, slides, and liquefaction features have been found as is typical for an earthquake of this size. Double-difference relocations of 370 aftershocks show a linear pattern of events and define a clear NE-SW striking mainshock fault plane. The hypocentrer was determined at 18 km depth beneath village Mihoi in SW Achaia. The 24-hr aftershock region extends approximately 30 km in length, and the width of the surface projection of the aftershocks ranges between 5–10 km. The depth of the aftershocks rarely exceeds 22 km. Analysis of high-rate GPS data showed that station RLS (Riolos) which is located 12.8 km N5°W of the epicenter was displaced co-seismically 7 mm to the North in agreement with right-lateral kinematics of the rupture. Static (Coulomb) stress transfer analysis indicates loading of faults near the towns of Patras (north) and Amaliada (south), respectively. The earthquake put more emphasis on the role of strike-slip in the deformation of western Greece also indicating that seismic strain is partitioned between strike-slip and normal-slip events due to obliquity of the Nubia (Africa) – Eurasia convergence.     

Using provenance data to assess archaeological landscapes: an example from Calabria, Italy

Ceramic provenance studies have helped archaeologists examine trade and exchange in multiple scales, the organization of production, and even vessel function. Yet, they may go even further, to provide a venue for the examination of past people’s perception of their landscape. To do so, a methodology is needed that links the choices prehistoric potters made, as reflected in their ceramics, with the choices their landscape could afford them, as reflected in the extent and distribution of local clays, and the physical, chemical and mineralogical characteristics of these clays. Using the region of Bova Marina in southwestern Calabria as a case study, we have combined a raw materials survey with field and laboratory experiments, along with chemical and mineralogical analyses of the collected sediments to understand the distribution and the physical, chemical and mineralogical variability of locally available clays and provide baseline data against which prehistoric ceramic materials from the region may be compared. We show that the local sediments can be divided into three major units, based on their macroscopic, mineralogical and chemical characteristics, that correspond well with the major geological units outcropping in the study area. While two of these units have internally consistent properties, the third is variable.     

TEXTURAL ANALYSIS OF CERAMIC THIN SECTIONS: EVALUATION OF GRAIN SAMPLING PROCEDURES

‘Textural analysis’ is being increasingly used for the characterisation of pottery fabrics. In this study we have investigated some of the effects on the observed size distribution data of applying a number of different grain selection procedures (principally various point-counting and ribbon-counting procedures). The results indicate that significant differences may arise from the application of the various techniques of grain selection and it is important that appropriate procedures be rigorously applied.     

The Aswan High Dam and the International Rescue Nubia Campaign

The preservation of the legacy of mankind is no less important than the construction of dams, the erection of factories and the greater prosperity of peoples (President Gamal Abdel-Nasser, cited in Säve-Söderberg 1987, 90). The Nubia Campaign mounted with the aim of salvaging the archaeological sites threatened by the construction of the Aswan High Dam (1960–1971) was the first collaborative international rescue effort involving UNESCO. One of the main outcomes of this campaign was the valorization of what came to be known as “world heritage” and the establishment of a UNESCO World Heritage Center entrusted with the mission to safeguard the cultural heritage of humankind. As we approach the 50th anniversary of the Nubia Campaign and as more sites are increasingly in need of international drives to rescue them from dams and other threats, this contribution provides a critical assessment of this historical event highlighting the role of foreign scholars and institutions, governments, organizational infrastructures, sources of funding, activities undertaken, as well as the impact of the dam on Nubians. In retrospect and in light of what happened to the preservation of Egyptian and Sudanese heritage as work of the foreign missions united by a single cause came to end, and considering the ongoing projects in Egypt and the Sudan that require urgent international efforts, I canvass the shortcomings of the Nubia Campaign in order to come up with recommendations for immediate action.     

Examination of Tattoos on Mummified Tissue using Infra-red Reflectography

Tattoos can have cultural or medical significance. Occasionally, evidence of this type of body modification may be found in archaeological remains. This paper describes three tattoos found in a collection of human remains from the site of Semna South in Sudanese Nubia. The tattoos date to the Meroitic period, about 2000 years ago. Two tattoos were located on the dorsal surfaces of naturally mummified hands. These tattoos were examined using infra-red reflectography to enhance visibility. The tattoos are relatively complex designs and may relate to the social status or the group affiliation of the individuals bearing them.     

IBERIAN CERAMIC PRODUCTION FROM BASTI (BAZA,SPAIN): FIRST GEOCHEMICAL,MINERALOGICAL AND TEXTURAL CHARACTERIZATION

Ceramic fragments from the archaeological excavation of the Iberian–Roman city of Basti (Spain) were studied from a geochemical point of view and by applying a statistical tool to X‐ray fluorescence data to discover similarities between ceramic materials. The analysis of these samples was completed by performing a mineralogical analysis, textural observation, and by characterizing the porous system and the colour of the pieces. Our results enabled us to identify the source area of the clayey raw material in the surroundings of Basti and to estimate the firing temperature of the ceramics. Differences in the chemistry were confirmed by characteristics of the pastes and the mineralogical composition of the pieces. Some samples show black cores, which would suggest the presence of organic matter in the raw material and fast firing of the ceramics. The main types of temper were quartz grains and gneiss fragments, although carbonate grains were also identified. Our evidence suggests that most of the samples were well fired. New silicate phases were found to be present in several samples. The mercury intrusion porosimetry verified and confirmed the firing temperature of non‐carbonated samples. Colorimetry showed that the colour of the ceramics varied according to the amount of CaO that they contained.     

Provenance study of early and middle bronze age pottery from Kaman-Kalehöyük,Turkey, by heavy mineral analysis and geochemical analysis of individual hornblende grains

The provenance of Early Bronze Age and early Middle Bronze Age pottery produced between 2100 and 1970 B.C. and excavated from Kaman-Kalehöyük, Turkey was studied using mineralogical methods, including heavy mineral analysis and geochemical study of individual hornblende grains. The relative abundances of heavy minerals in the fabrics of 20 Early Bronze Age (EBA) and early Middle Bronze Age (MBA) pottery sherds, together with 27 local sediments collected within a radius of 25 km of the site were studied. The heavy mineral distributions in the Kaman region were statistically analyzed for consistencies in their occurrence. Amphibole was found to be the most abundant heavy mineral in most of the analyzed samples, followed by titanite and epidote. The amounts of other minerals such as garnet, clinopyroxene, and zircon are subordinate. Different proportions of heavy minerals in the fabrics allow categorization of the EBA and early MBA potteries into 5 groups. Comparative study of heavy mineral assemblages of local sediments and pottery suggests that half of the EBA and most of the MBA potteries were produced from sediment near the excavation site, whereas the other half of the EBA potteries were produced from sediment occurring at 25 km east or more east of the site. The geochemistry of individual amphibole grains was studied by electron-microprobe analysis. Most of the studied amphibole grains are calcic and aluminous, corresponding to hornblende. They can be further characterized into four types based on their chemical composition. The combination of heavy mineral identity and hornblende geochemistry provides diagnostic evidence for the origins of Kaman-Kalehöyük pottery. These and analogous heavy mineral techniques are effective archaeometric tools for determining pottery provenance.     

RECENTLY IDENTIFIED EGYPTIAN PIGMENTS

On several bowls from Nubia (1600 b.c. ) and on one canopic jar (New Kingdom) huntite, a calciummagnesium-carbonate CaCO₃. 3MgCO₃ was identified by means of X-ray diffraction and infra-red absorption techniques. Vases from the Amarna period (1370 b.c. ) are decorated with a blue paint, which proved to be cobalt-blue. Copper chloride atacamite was used on limestone reliefs from Thebes-West but the green frit chrysocolla occurs more frequently on Egyptian objects as is mentioned in literature.
