THE STUCCO TECHNIQUE OF THE MAGISTRI COMACINI: THE CASE STUDY OF SANTA MARIA DEI GHIRLI IN CAMPIONE D'ITALIA (COMO,ITALY)

This paper is aimed at defining the artistic technique performed by the outstanding artist Isidoro Bianchi for the Baroque stucco decorations in the church of Santa Maria dei Ghirli (Campione d'Italia, Italy). Samples of stucco were examined by means of optical microscopy, scanning electron microscopy with a microprobe, X‐ray powder diffraction, Fourier transform infrared spectroscopy, gas chromatography–mass spectrometry and laser ablation mass spectrometry equipped with plasma source spectrometry. On the basis of the results obtained, art historians have made new hypotheses on the biography of the artist and on the historical location of his birthplace.     

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.     

SHAFT‐HOLE AXES FROM CAPUT ADRIAE MADE FROM AMPHIBOLE‐RICH METABASITES: EVIDENCE OF CONNECTIONS BETWEEN NORTHEASTERN ITALY AND CENTRAL EUROPE DURING THE FIFTH MILLENNIUM BC

Here we show the results of a study concerning a small group of shaft‐hole axes found in northeastern Italy, made from amphibole‐rich metabasites, fine‐grained and free of phenoblasts. The main mineral phases are amphibole, ranging from actinolite to hornblende, and plagioclase (An_10–15 and An_70–77). The amphiboles generally show a needle shape and are often radially arranged. Quartz is present in thin veinlets, while ilmenite is widespread in small patches. The petrographic and geochemical features suggest that the axes originate from the southern thermal aureole of Tanvald granite in northern Bohemia. In accordance with this provenance, the typology of the tools shows similarities with the perforated shoe‐last axes spread across Central Europe during the fifth millennium bc and made from similar raw material. For the first time, these axes give evidence of long‐distance (about 800 km) contacts between northeastern Italy and Central Europe during the Neolithic.     

ARCHAEOLOGICAL AMBERS FROM NORTHERN ITALY: AN FTIR–DRIFT STUDY OF PROVENANCE BY COMPARISON WITH THE GEOLOGICAL AMBER DATABASE*

European geological ambers of five different localities and types, and Italian geological ambers from seven different deposits have been studied with Fourier transform infrared spectroscopy (FTIR) and diffuse‐reflectance infrared Fourier transform (DRIFT). Ambers from several localities have been characterized for the first time. The research aims to create a database of European ambers, containing both FTIR and DRIFT data. The FTIR spectra are easily comparable with the data commonly available in the literature, whereas DRIFT analyses are shown to be more useful to characterize the archaeological finds. The provenance of several archaeological ambers from northern and southern Italy, dating from the Middle Bronze Age to the Iron Age, is assessed on the basis of the developed database. Of the 35 analysed archaeological objects, all but five are composed of Baltic succinite amber.     

THE RADIOCARBON CHRONOLOGY OF THE NEOLITHIC AND COPPER AGE OF NORTHERN ITALY

Summary. Until twenty years ago the chronology of the Neolithic and Copper Age settlement of Northern Italy was almost exclusively based on the stratigraphical sequence of the Arene Candide cave in Liguria. The research carried out since the sixties has strongly increased our knowledge of the earliest farming communities and the first copper using people who inhabited the country between the end of the seventh and the beginning of the fourth millennium BP. This article considers the available evidence for this period which is now supported by a good set of radiocarbon dates.     

风险视角下的城市聚落形成模拟

幂次法则是普遍存在于自然科学和社会科学界的现象,而城市位序-规模法则是幂次法则在城市科学中的体现之一,然而特定城市规模分布一直缺乏完整的解释。本文尝试结合城市增长过程中土地开发行为的报酬递增规则与土地开发主体的风险认知行为,以城市增长的微观过程为切入视角模拟宏观城市聚落演化过程,进而探讨风险态度对城市聚落形态,尤其是对其规模分布的影响。研究结果表明：①即使城市聚落演化过程中存在多种风险态度,幂次法则在城市聚落的规模分布中仍保持着稳健性; ②现实世界中城市聚落规模分布的变异和稳定可能来自城市主体风险态度的多样性。     

A DAMAGE MODEL FOR THE ANALYSIS OF THE SEISMIC RESPONSE OF MONUMENTAL BUILDINGS

In this paper the Author proposes a damage model for the analysis of masonry plates and shells, which is based on an improvement of a previous constitutive model. The modifications introduced, connected to the head joint damage, allow us to study the influence of masonry texture on the damage modes once the mechanical characteristics of the elements constituting the masonry and the results of tests on simple assemblages are known. Having a nonlinear constitutive model is certainly one of the basic elements for understanding the damage mechanisms in masonry buildings. If, in fact, an elastic-linear constitutive model may be used under normal loading conditions, in critical situations it is necessary to model the damage and the dissipation mechanisms that occur between the elements, stone (brick) and mortar, in correlation with their characteristics and kind of masonry. To validate the model a comparison is made between the numerical and experimental results, in the case of tests available in the literature in masonry panels subjected to out-of plane loading and in a real structure through the observation of the damage in Umbria (Italy) surveyed after the 1997 earthquake.     

THE BAYKAL-AMUR MAINLINE AND THE INTEGRATED ECONOMIC DEVELOPMENT OF THE EASTERN REGIONS OF THE USSR

The construction of the BAM is viewed as serving two purposes: one, the development of new resource sites for export through Soviet Pacific ports, particularly to Japan; second, the accelerated development of new parts of East Siberia and the Far East, serving ultimately as a bridgehead for further advance toward the Northeast. Key resource areas to be given priority in development are the Neryungri coking-coal basin of South Yakutia, for export to Japan; the Udokan copper deposit, and the Molodezhnoye asbestos deposit. Because of the harsh environment, it is unlikely that any processing activities beyond mineral concentration and forest products industries will be located in the BAM zone, at least in the early stages of development. Food supply for the growing population will be largely dependent on hauls of bread and feed grains from southern portions of West Siberia and vegetables from as far away as Central Asia. Future territorial production complexes along the BAM are tentatively outlined.     

AN EPR AND ISOTOPIC STUDY OF THE MARBLES OF THE TRAJAN's ARCH AT ANCONA: AN EXAMPLE OF ALLEGED HYMETTIAN PROVENANCE*

The provenance of 20 marble samples drawn from the Trajan's arch at Ancona, which is supposed to be made of Greek, Hymettian marble, has been established on the basis of the independent use of EPR and isotopic data. The results of the two methods are in good agreement and unequivocally indicate a Proconnesian provenance. Sixteen samples are assigned to this site, whereas two are classified as untypical Proconnesian samples and the remaining two are assigned an unlikely Parian provenance. No indication exists for a possible Hymettian origin of the marbles. A multi‐method approach, which employs all of the experimental variables simultaneously, demonstrates that the 18 samples identified as Proconnesian belong to several different quarrying areas within the site. This result is taken as an indication that the Proconnesian quarries were run following a highly organized, semi‐industrial production model. The origin of the Hymettian/Proconnesian misunderstanding and the possible misclassification of other Roman monuments in Italy are briefly commented on.     

ASSESSMENT OF THE NATURAL FREQUENCY OF THE SEDIMENTARY COVER IN THE COLOGNE AREA (GERMANY) USING NOISE MEASUREMENTS

Noise measurements were carried out at 381 sites in the Cologne area (Germany) using both short period and broad band sensors. The large number of data allowed both assesment of the influence of different sensors in the site response estimation and to compare the widely used H/V technique with the recently proposed Fourier Phase Spectral Method (FPSM). The results show that short period sensors are able to reliably retrieve site effects at frequencies well below their corner frequencies. Moreover, the H/V method should be preferred to the FPSM in determining the fundamental resonance frequency of soils. Finally, a map showing the resonance frequency distribution in the studied area was drawn using the results obtained applying the H/V technique.     

A LYONS BRANCH OF THE POTTERY-MAKING FIRM OF ATEIUS OF AREZZO

Fifty-one waster sherds of Terra Sigillata (～20-0 b.c. ) from Arezzo, Italy and Lyons, France have been chemically analysed for twenty-eight elements by neutron activation and seven by X-ray fluorescence. Most of the elemental abundances were measured with high precision and cross-comparisons of the two techniques of measurement (and sample preparation) give added insight as to their relative precision, the calibration differences and the extent to which volatile materials such as carbonate or water influence the results. The sherds from Arezzo formed a homogeneous and distinctive chemical group while all but two of those from Lyons were classified into three such groups. Two of the Lyons groups (MML A and MML B) were from Montée de La Muette and one was from Loyasse. Four additional sherds from houses excavated in Strasbourg and one from Lyons, all of which bore the signature of the famous Anetine pottery-making firm of Ateius, were also analyzed by the same techniques. These signed sherds all had the same composition pattern and it closely matched one of those from Montée de La Muette (MML A) in Lyons. It is therefore suggested that these five sherds bearing the Ateius signature were made in the general vicinity of Lyons and were part of the output of an as yet unknown Gallic branch of the firm of Ateius.     

BEYOND INTERMARRIAGE: THE ROLE OF THE INDIGENOUS ITALIC POPULATION AT PITHEKOUSSAI

Debate has long raged over the nature and extent of contact and cooperation between the Greeks and the Levantines at the site of Pithekoussai on the Tyrrhenian coast of Italy. The native Italic population, however, has been largely overlooked or viewed as a marginal or fringe element. Italic fibula types, which are found extensively in the cemetery, have been traditionally interpreted as evidence for the intermarriage of Italic females into the colonial settlement. This concept has limited our understanding of the role or impact of the Italic population at the site, effectively obscuring any more nuanced or balanced interpretations of their activity. A detailed analysis of several tombs from Pithekoussai, which contained iron tools or instruments, indicates that the Italic population was more actively involved in the creation of material culture at the site than has previously been supposed. Parallels for the practice are found widely on the Italic mainland and have often been associated with elite customs or funerary rituals. The presence of such practices at the site of Pithekoussai indicates the active impact of the native Italic population and the dynamic effect that diverse members of the community had on the creation and promulgation of a uniquely Pithekoussan identity.     

PROBLEMS IN THE SPATIAL REDISTRIBUTION OF STREAMFLOW

A report on a 1974 conference on interbasin transfers from Siberia to Central Asia compares the alternative stream-diversion projects west and east of the Urals and finds that north-south interbasin transfers in the European part of the country have a better chance for early implementation than the diversion from Siberia to Central Asia. The author urges consideration of a unified water-management system within the European part of the Soviet Union that would make it possible to dispatch streamflow from one basin to another much as electric power is transmitted through interconnections between power grids. Such an interconnected water-management system would be based on the premise that runoff volumes tend to be nonconcurrent in the various drainage basins of the Russian plain so that surplus runoff from “donor rivers” (Pechora, Northern Dvina, Onega and the lakes Onega and Ladoga) might be channeled southward to “consumer rivers” (Volga, Don, Dnieper and Ural).     

WHEELS WITH THICKENED SPOKES, AND THE PROBLEM OF CULTURAL CONTACT BETWEEN THE AEGEAN WORLD AND EUROPE IN THE LATE BRONZE AGE

Summary. A technological advance in wheel construction, entailing spokes with thickened or strengthened ends, can be detected in Central Europe at the start of the Late Bronze Age. Spokes with thickened ends are seen in Central Europe on full-size wheels, wagon models and wheel depictions. It is argued that this technological innovation had its source in the Aegean, where wheels with thickened spokes are seen not only depicted on late Mycenaean craters but also on Linear B wheel ideograms. The second part of the article discusses a closely-related Central European group of wheel-shaped designs, characterised by forked spokes, found on pin-heads, pendants, decorated belt-sheets, phalerae and belt-hooks. As some of these designs refer to real wheels constructed with thickened or strengthened spoke ends, it is concluded that the designs really represent wheels, although the designs are often so simplified that this is not immediately apparent.     

FISHERS OF THE CORDED WARE CULTURE IN THE EASTERN BALTIC

Between 2800 and 2400 cal BC pastoralists from Central Europe migrated into the eastern Baltic paving the way for the Corded Ware Culture (CWC), and a new type of economy, animal husbandry. Traditionally the CWC people were viewed as highly mobile due to the lack of substantial traces of dwellings and material culture at settlement sites; they were reliant on an economy based on animal husbandry as demonstrated by zooarchaeological and stable isotopic evidence. However, this paradigm is beginning to shift. Here, we present new AMS radiocarbon (¹⁴C) measurements, pollen and macrobotanical data from sediment samples and a portable fish screen, as well as technological, molecular and isotopic data obtained from ceramic vessels from three CWC sites in the eastern Baltic. Overall, our results indicate a de-Neolithisation process undergone by some CWC groups, particularly in lacustrine and coastal ecotones, and a shift to hunting, gathering and fishing.     

THE ACCURACY OF THE SPECIFIC GRAVITY METHOD FOR THE ANALYSIS OF GOLD ALLOYS

Two possible sources of error in the measurement and interpretation of the specific gravities of gold coins are investigated. First, the effect of the presence of copper was measured and found to be more significant than previously thought. It is shown that the presence of 5% of copper in a gold-silver alloy results in a measured gold content which is 3.3% too low when the coin is analysed by the specific gravity method. Secondly, the importance of cleaning the coins before measuring the specific gravity is also demonstrated.     

ARCHAEOMETRIC STUDY OF PROTOHISTORIC GRINDING TOOLS OF VOLCANIC ROCKS FOUND IN THE KARST (ITALY–SLOVENIA) AND ISTRIA (CROATIA)*

This paper presents the results of the archaeometric study of 30 grinding tools found in the Karst plateau (an area that spreads from the northeastern border of Italy to Slovenia) and in the Istria peninsula (Croatia). The petrographic and geochemical characteristics of the artefacts indicate that most of them would be made of trachytic volcanites extracted from the Euganean Hills, near Padua (Veneto). It is known that trachytic rocks from this area had been widely exploited in northern Italy during protohistoric times, but these data considerably enlarge the area of diffusion of saddle‐querns made of these rocks, extending it to Istria. Additionally, the likely provenance from Mount Etna of few other pieces of mugearites and hawaiites represents a new element, to be fully evaluated in the context of trans‐Adriatic exchange/trade connections. Analytical data and possible archaeological inferences are presented in detail in the text.     

A MULTIDISCIPLINARY APPROACH TO THE CHARACTERIZATION OF ROMAN GRAVESTONES FROM AQUILEIA (UDINE,ITALY)*

The results of an archaeometric study on gravestone production in Aquileia (northeastern Italy) during Roman Republican times are reported here. The artefacts are made of limestone, quarried from the sedimentary sequence of the Trieste Karst (Carnican Alps, northeastern Italy), as testified by historical sources which refer to the ‘Roman Quarry’ at Aurisina. The rock types used for the gravestones are petrographically, geochemically and geochronologically homogeneous, and display similar faunal assemblages. In addition, their age is restricted to the Santonian – Lower Campanian. Comparisons between archaeological finds and rock specimens from various active and inactive quarries in this area suggest that quarrying during Roman Republican times was limited to a specific stratigraphic horizon of the sedimentary sequence, corresponding to the higher part of the ‘Roman Quarry’.     

GEOGRAPHICAL ASPECTS OF A TERRITORIAL REDISTRIBUTION OF WATER RESOURCES IN THE USSR

A set of principles for a geographical research program relating to the future impact of major interbasin water transfers is outlined. Such a program, evaluating the impact of proposed tranfers both in the European USSR and in the Midland Region of Western Siberia, Kazakhstan and Central Asia, should be based on the following considerations. Noneconomic criteria, such as the environmental impact of water transfers, must be given as much attention as economic and engineering criteria. Experience suggests that any measures designed to protect or ameliorate the environment, for example, inland fisheries, should precede actual water-project construction by at least 15 to 20 years. North-south transfers should be so designed as to benefit both the northern region, from which water is to be withdrawn, and the southern region, where water resources are to be enhanced. The problem of interbasin transfers should be accompanied by a program of intensification of water use, measured by a reduction of water input into the economy per unit of output. Water use can be intensified by such measures as shifting grain production from south to north and building irrigation reservoirs in Central Asian mountains to regulate runoff.
