TECHNICAL STUDY OF A CEREMONIAL SICAN TUMI FIGURINE

Examination of a Sican ceremonial tumi, dated to the Middle Sican, c. AD 850–1050, showed that it was made in a silver-copper alloy of approximate composition 93% silver, 6% copper. Many separate pieces are used in the construction, joined together by both mechanical methods and by solder. The principal figure has been made from 18 separate silver sheets, with 169 separate parts identified in the head-dress, totalling 187 design elements. Metallographic examination of a fragment of repoussé decorated sheet from the figure surmounting the tumi surprisingly showed that the silver-copper alloy has a cast morphology; this demonstrates that Sican metalsmiths were pre-casting silver-copper sheet into the dimensions required for making the tumi, rather than carrying out the expected process of making the idol from hammered silver-copper sheet, shaped by extensive cycles of working and annealing, thus contradicting the usual assumptions about the manufacture of sheet-metalwork made in such cases.     

KOSELLECK,ARENDT, AND THE ANTHROPOLOGY OF HISTORICAL EXPERIENCE

This essay is the first attempt to compare Reinhart Koselleck's Historik with Hannah Arendt's political anthropology and her critique of the modern concept of history. Koselleck is well‐known for his work on conceptual history as well as for his theory of historical time(s). It is my contention that these different projects are bound together by Koselleck's Historik, that is, his theory of possible histories. This can be shown through an examination of his writings from Critique and Crisis to his final essays on historical anthropology, most of which have not yet been translated into English. Conversely, Arendt's political theory has in recent years been the subject of numerous interpretations that do not take into account her views about history. By comparing the anthropological categories found in Koselleck's Historik with Arendt's political anthropology, I identify similar intellectual lineages in them (Heidegger, Löwith, Schmitt) as well as shared political sentiments, in particular the anti‐totalitarian impulse of the postwar era. More importantly, Koselleck's theory of the preconditions of possible histories and Arendt's theory of the preconditions of the political, I argue, transcend these lineages and sentiments by providing essential categories for the analysis of historical experience.     

THE ESTABLISHMENT OF A DATA BASE OF NEUTRON ACTIVATION ANALYSES OF WHITE MARBLE*

The establishment of a data base of trace element analysis results obtained by neutron activation analysis of 183 marble samples, each weighing about 200 mg, from eight different quarrying localities for use in provenance studies is described and a summary of the results presented. The problems of sampling museum artefacts are discussed, and details of tests of the reproducibility of the technique are given together with those obtained from multiple-samples from single museum objects. Replicate analyses of a marble standard are also discussed. Thus these data are a measure of the accuracy and precision of the technique, as well as allowing an assessment of the variation in trace element composition within quarry sources and single blocks of marble, as used for artefacts.     

THE SECTILIA PANELS OF FARAGOLA (ASCOLI SATRIANO,SOUTHERN ITALY): A MULTI‐ANALYTICAL STUDY OF THE GREEN,MARBLED (GREEN AND YELLOW), BLUE AND BLACKISH GLASS SLABS

Analyses at the Cu–K, Fe–K and Mn–K edge were performed to study the green, marbled (green and yellow), blue and blackish (deep greyish olive green) glass slabs decorating three sectilia panels from the archaeological site of Faragola. Results indicate that all slabs were made by mixing siliceous sand with natron, sometimes probably mixed with small percentages of plant ash. Cu²⁺ and Pb antimonates should be responsible for the opaque green colours. The dark green and yellow portions of the marbled slabs are respectively comparable to the slabs comprising only one of these colours. Cu²⁺ together with Ca antimonates probably produced light blue slabs, whereas cobalt was used to produce dark blue slabs. We consider it possible that the abundance ratio of Fe²⁺/Fe³⁺ and the complex Fe³⁺S^2? would have an effect on the blackish slabs. The contribution of Mn cannot be ascertained even if it could have played a role in darkening glass colour. The comparison between the chemical composition of Faragola samples and several glass reference groups provided no conclusive evidence of provenance; whereas, the presence of a secondary local workshop can be hypothesized.     

THE AMBER OF EL DORADO: CLASS IB ARCHAEOLOGICAL AMBERS ASSOCIATED WITH LAGUNA GUATAVITA*

Laguna Guatavita, a crater‐like lake located in central Colombia, was used by pre‐Columbian Muisca people for a variety of socio‐religious ceremonies, many of which involved casting offerings into the lake. Of these, the installation of a new ‘king’ became the basis of the El Dorado myth that was carried back to Europe by 16th century conquistadores. In the present study, beads collected from Laguna Guatavita during a late 19th/early 20th century attempt to recover valuables from the lake bed, have been subjected to geochemical analysis. Results establish that these artefacts have been fabricated from Class Ib amber. Class Ib ambers have not previously been reported in either the geological or archaeological records of Central or South America, and their existence in this context implies that the Muisca people had access to a unique local or regional source of amber, knowledge of which has subsequently been lost.     

On the Sexagenary Cycle of the Tibetans

This study examines Zuozhuan narrative accounts that conclude with evaluations ascribed to the “Gentleman” (junzi 君子). The Zuozhuan is one of the earliest extant Chinese works of narrative history, and in the past many scholars assumed that narrative accounts formed its core, dismissing subjective evaluations of those accounts, such as the Gentleman's comments, as secondary, later additions. This study demonstrates that narrative account plus Gentleman judgment function together as a unit, contending that these units were likely introduced into the Zuozhuan as such. It further proposes that the perception that the Gentleman's concluding comments were later, independent additions was likely influenced by the practice of capping narrative accounts with quotations borrowed from other sources, and furthermore, suggests that this perception may have led compilers on occasion to insert material between the narrative accounts and the Gentleman's evaluations of them.     

CHEMICAL COMPARISON OF RARE CHINESE WHITE POTTERY FROM FOUR SITES OF THE ERLITOU STATE: RESULTS AND ARCHAEOMETRICAL IMPLICATIONS

White pottery is among the most significant finds from China's earliest state, Erlitou (c. 1900–1500 bc ). Samples were primarily discovered in small numbers from elite tombs of a few sites, leading to the hypothesis that they were made at only a few locations and then circulated regionally as prestige items. To facilitate determining provenances, we compare the ICP–MS trace elements and TIMS Sr isotopes of whiteware with two soil samples from Nanwa, a possible manufacturing site, and with shards found at three other sites: Erlitou, Huizui and Nanzhai. The Nanwa shards demonstrate special elemental and Sr isotopic features. Considering the chemical observation and archaeological background together, we propose that Nanwa was a centre for whiteware production, although the two soil samples we collected there were probably not the exact materials used. Some whiteware pieces from Erlitou, Huizui and Nanzhai fall in the chemical field defined by Nanwa samples, indicating that they were possibly made at Nanwa. Many other samples from these three sites plot outside the Nanwa field, implying they were probably not Nanwa products. This study demonstrates that while chemical sourcing is very useful, firm archaeological context must remain the cornerstone of such research.     

GAMBLING WITH ETRUSCAN DICE: A TALE OF NUMBERS AND LETTERS

The graphical and linguistic interpretation of the first six Etruscan numerals has long been confronted with the ambiguous assignment of the words huth and sa to either 4 or 6. Here, we show how the systematic combinatorial analysis of the numerals appearing on ancient southern Etrurian dice dated from the eighth to the third centuries bc , together with the careful comparison of the results with the only two existing dice carrying the alphabetical translations of the numerals conserved at the Bibliothèque Nationale de France, Paris, finally allows unambiguous mathematical resolution of the linguistic riddle, allowing the firm attribution of the numeral 6 to the graphical value huth and 4 to sa. Combinatorial analysis of the numerals distribution on the six faces of the die shows that only two of the 15 possible numerical combinations were actually in use in southern Etruria, and that during the fifth century bc there was a marked shift from the typical (1–2, 3–4, 5–6) combination used in the early seventh‐ to fifth‐century bc dice to the (1–6, 2–5, 3–4) combination used at later times and still largely adopted today. The largest body of archaeometric data on dice specimens from Etruria is presented, based on macroscopic examination, X‐ray diffraction, DRIFT spectroscopy and density measurements.     

STUDIES OF CERAMIC TILES ATTRIBUTED TO GABRIEL DEL BARCO

This study reports the mineralogical and chemical characterization of the ceramic body of tiles created by Gabriel del Barco, an important tile painter in Lisbon from the 17th century. Six tile panels were studied: four are signed and two are attributed to the painter. The results obtained from the signed panels revealed that the samples have almost the same characteristics, with a magnesium‐rich phase, meaning that the artist, or the pottery where the tiles were made, kept to the same manufacturing procedure over some time. In contrast to this, the results of samples from the masterpiece Vista de Lisboa showed some heterogeneity, as two patterns were observed. However, one of these patterns matches with the one observed in the signed tile panels. Although a more detailed study still needs to be done, these findings, together with historical sources linked to painting characteristics, suggest that Gabriel del Barco was also the author of the non‐signed tiles.     

Chronic Maxillary Sinusitis in Medieval Sigtuna,Sweden: A Study of Sinus Health and Effects on Bone Preservation

Frequencies of maxillary sinusitis in the population of the medieval town Sigtuna, Sweden, were examined. The first aim was to explore the occurrence of sinus conditions in this urban population, and the second was to investigate the effects of preservation in relation to these changes. The skeletal sample consisted of 274 adolescent and adult individuals buried ca 970–1530 AD. The maxillary sinuses were examined for different types of skeletal change related to sinusitis. The severity and location of these changes were recorded, together with the preservation of the sinus. When the diagnostic criteria for bone preservation from previous studies was used, i.e. the preservation of at least one complete antral floor, the results showed that 97.7% (n = 157) of the individuals were affected, with older individuals showing more severe bone changes. In the entire (i.e. more fragmented) sample, 94.5% (n = 259) showed signs of sinusitis. Again, older individuals showed more severe bone changes, and males were more frequently affected. Also, an increased frequency over time was found. The maxillae were subdivided into groups of bone preservation, and the results showed that there was a significant relation between preservation and the registered presence and severity of sinusitis. The results may be used as a cautionary note against investigating the occurrence of maxillary sinusitis without considering the skeletal preservation factor. There was no correlation between preservation and sex or age groups. This suggests that the differences between younger and older and male and female were not a result of preservation alone and could be considered as trustworthy.

THE EMIGRATION OF PREALPINE LAKE MASTERS: A STUDY OF A 17TH‐CENTURY MANTELPIECE ATTRIBUTED TO THE CARLONE FAMILY OF ROVIO (TICINO,SWITZERLAND)*

This work illustrates the possible connections between the phenomenon of the seasonal emigration of lake masters and the production of artistic artefacts. Within the ambit of these dynamics, a stucco mantelpiece was taken into consideration. Nothing was known about the object: neither its origin, nor the artist who produced it, nor the period of execution. Historical, stylistic and formal analyses of the materials and of the technique with which the work was executed allow us to verify that the mantelpiece was produced using the stucco technique in the 17th century, in Rovio (southern Switzerland, Ticino), and that it comes from one of the exponents of the Carlone workshop, whose representatives were important in the tradition of itinerant artistic workers. Due to their good technical and professional specialization, the Carlone workshop served both public and private buyers. Tommaso Carlone is the principal representative artist of the Carlone workshop; it is certain that his workshop produced the stucco mantelpiece. The migrations of the artists were seasonal and they maintained a close bond with their country of origin. When they returned to the country of origin, they produced works of great artistic value, of which the mantelpiece represents a splendid example. Through the employment of conventional analytical techniques (optical and electron microscopy, infrared spectroscopy and porosity measurements), it has been possible to study the technique with which the work was executed, the materials used and the decay. The mantelpiece was produced using the stucco technique by means of a body layer (slaked lime and silicate and carbonate aggregates) and a marmorino finishing layer (slaked lime and pointed calcite crystals). Above this layer, whose thickness varies in relation to the executed result, there is a thin lime plaster whitewash, pigmented with the dispersion of yellow ochre particles; chromatic alterations are an oxalate patina caused by firm adhesion to the marmorino layer, due to the denaturation of the proteic substances employed. The final treatment was made with beeswax, which increased the marmoreal effect. Several additional layers of lime plaster whitewash have also been applied over the centuries. The figurative central square of the plastic decoration was made using red ochre.     

ONLY TIME WILL TELL: A REVIEW OF THE METHODOLOGY OF DIRECT ROCK ART DATING

Epistemology has not kept pace with the progress experienced in the direct dating of rock art. This paper reviews the experimental methods that have been developed in recent years. While many do provide important information about the possible age of rock art, it is of concern that the precipitate archaeological interpretations these data are used for are often not warranted. Some are attributable to not understanding the severe qualifications that apply to most dating results, others perhaps to over-enthusiasm on the part of some researchers. The introduction of archaeological dynamics into direct dating of rock art threatens the reliability of this young methodology. Some of the pitfalls are considered in this paper, and a general rationale for the direct dating of rock art is developed.     

A STUDY OF CHINESE PORCELAIN RAW MATERIALS FOR DING,XING, GONGXIAN AND DEHUA WARES*

The raw material used largely determines the type and quality of porcelain produced. Twenty-three raw materials used for making Ding, Xing, Gongxian and Dehua porcelain bodies were studied using principal component analysis. Results show that for Dehua wares, only one raw material was used. For Ding wares, although there were many possible raw materials, the use of one alone is unlikely. Lingshan clay was the main raw material but it has to be mixed with other raw materials: Pinjiawa clay, quartz, feldspar and dolomite. The Xing pieces can be divided into three groups and Gongxian wares into two groups, which are discussed in detail.     

THE DETERMINATION OF BRICK PROVENANCE AND TECHNOLOGY USING ANALYTICAL TECHNIQUES FROM THE PHYSICAL SCIENCES*†

This work applies established analytical techniques from the physical sciences to Irish brick, in order to gather evidence of ceramic technologies, provenance and sources of raw materials. Petrographic microscopy, X‐ray diffractometry and scanning electron microscopy with an energy‐dispersive X‐ray diffraction attachment were used to study the brick of Rathfarham Castle, Dublin, built c. 1618, where clay brick was introduced in 1771. Local clay was fired in the laboratory and analysed in a similar manner. The petrography of the pointing mortar was studied in order to gather evidence of ceramic provenance. This paper concludes that the brick was hand‐ moulded with a silica‐based, predominantly non‐calcareous clay of glacial origin, gathered locally, including fluxes and a high percentage of non‐plastic material. The mineralogy and petrography of the brick, together with the presence of pebbles and a coarse matrix, suggest that the raw clay was probably gathered from a glacial deposit. The presence of abundant pebbles and colour inhomogeneities suggests a lack of processing of the raw clay. The brick was probably fired in clamps at top firing temperatures ranging from 750°C to above 900°C. Transformation of limestone temper involving the breakdown of calcite and the generation of calcium silicates, and the new formation of plagioclase, high‐temperature quartz, hematite and spinel were revealed. The presence of spinel in ‘hot spots’ indicates that fuel was added to the raw clay in order to assist firing.     

Towards an Anti-Western Stance: The Economic Discourse of Iran's 1979 Revolution

The Iranian Revolution of 1979 saw the mobilization and cooperation of a variety of groupings that were brought together by their shared determination to overthrow the Shah. However, it was not only opposition to the Pahlavi regime, but also suspicion of and disdain for that regime's Western backers that united these revolutionary groups. Religious leaders (ulama), merchants (bazaaris), intellectuals and students alike all espoused the strong anti-Western sentiments that had been developing in Iran over the previous two decades. But what particular factors can be seen to have encouraged the adoption of these sentiments in the lead-up to the revolution, and in what ways were they articulated and subsequently put into practice by the leaders of the new regime? This article suggests that various domestic and international influences can be seen to have shaped the emergence of Iran's revolutionary discourse of “economic independence.” In particular, the paper argues that a peculiar blend of Shi'i concepts of social justice and Marxist-Leninist discourses of class struggle and anti-imperialism not only informed the economic outlook of Iran's burgeoning revolutionary movement during the period 1953–79, but was also enshrined in the Constitution of the Islamic Republic.     

AN ATTEMPT AT DATING THE SWANSCOMBE SKULL BONES USING NON-DESTRUCTIVE GAMMA-RAY COUNTING

A low-background germanium spectrometer was used to measure the gamma-ray spectra of the three parts of the Swanscombe skull. Detailed studies of the method showed that it was possible to make accurate measurements of the content of ²²⁶ Ra and ²³¹ Pa but less accurate ones of ²³⁸U and ²³⁵U. Results from the three samples were inconsistent, showing that their exposure to radioactive ground water must have been very different, although they were found close together. The uncertainty in the ratio of ²³⁴U to ²³⁸U in the ground water and the lack of knowledge of the time at which the bones acquired the uranium also prevented the deduction of any reliable dates for these specimens.     

MOLECULAR AND ISOTOPIC DEMONSTRATION OF THE PROCESSING OF AQUATIC PRODUCTS IN NORTHERN EUROPEAN PREHISTORIC POTTERY*

A number of charred surface residues, adhering to ceramic containers, were obtained from various coastal and inland sites in north‐west Europe dating from the sixth to the fourth millennium cal bc . In order to investigate the use of these vessels and in particular to identify any marine products, the residues were subjected to carbon and nitrogen stable isotope analysis. Variation in carbon isotope ratios between different samples indicated that some vessels may have been used to process marine products. This analysis was corroborated by specific identification of aquatic products following structural and isotopic characterization of lipids extracted from selected samples.     

REAPPRAISAL OF MAGNITUDE OF 20TH CENTURY EARTHQUAKES IN SWITZERLAND

We reappraise the material needed to assess the 20th-century seismicity of Switzerland and of the adjacent areas of the Alps in terms of magnitude. For this we make use of macroseismic reports and literature and by calculating the surface-wave magnitude from the Prague formula of all significant earthquakes in the region. No attempt is made to relocate earthquake positions; instead their reliability is ranked using existing solutions and macroseismic observations We find that for small earthquakes (M _s >4.5), which constitute the bulk of the events in the region, the calculation of M _s observed at relatively short distances, requires station and distance corrections which can be significant. Also we find that recomputed Ms estimates differ from those reported in other earthquake catalogues. From this reappraisal of M _s and from a uniform re-evaluation of the associated macroseismic data, we derive a stable correlations between M _s and felt areas that can be used to assess the magnitude of historical, pre-instrumental, events for which only isoseismal radii (r _i ) and the associated intensities (I _i ) are available. We examined the conversion of surface-wave magnitude into moment magnitude, a conversion that presents some interesting problems for relatively small events for which the M _s -log(Mo) scaling changes. We conclude that the rate of moment release derived from events of M _s >4.0 is small, and that it should be associated with horizontal and vertical velocity rates of less than 1 mm/yr, too small vo be confirmed by GPS measurements over short periods of time so that can be used to constrain hazard assessment.     

THE CHARACTERIZATION OF PAINTS AND WATERPROOFING MATERIALS FROM THE SHIPWRECKS FOUND AT THE ARCHAEOLOGICAL SITE OF THE ETRUSCAN AND ROMAN HARBOUR OF PISA (ITALY)*

This work presents the results of a diagnostic survey on the shipwrecks from the archaeological site of the ancient harbour of San Rossore (Pisa, Italy). The original waterproofing, caulking and painting materials were characterized by Fourier transform infrared spectroscopy (FTIR), gas chromatography – mass spectrometry (GC–MS), energy‐dispersive X‐ray microanalysis (EDX) and X‐ray diffraction (XRD). The major constituents of the waterproofing and caulking materials detected on the planks were tricyclic abietanes showing a high degree of aromatization. These compounds are indicative of a pitch obtained from the wood of trees of the Pinaceae family. The analysis of the organic components of the paint samples revealed diterpenoid acids characteristic of Pinaceae resins together with linear long‐chain alcohols and fatty acids, highlighting the presence of beeswax. Noticeably, the characteristic odd carbon number alkanes that are normally present in beeswax were not detected. The EDX and XRD analyses showed that hematite, calcite, cerussite and kaolinite were employed as pigments to paint the ships’ hulls.
