SAND FOR ROMAN GLASS PRODUCTION: AN EXPERIMENTAL AND PHILOLOGICAL STUDY ON SOURCE OF SUPPLY*

This paper reports the results of an experimental study performed on Campanian littoral sand, together with a careful philological analysis of Pliny's text concerning the production of glass using the above sand in order to verify its suitability. Accurate chemical and mineralogical characterization of sand samples and experimental glasses was carried out, proving the unsuitability of sand for glass production in its original state. Taking into account both the results of the philological analysis of Pliny's text and the mineralogical assemblage of the sand, a new hypothesis regarding Roman glass‐making technology is proposed and tested here. The technology implies the production of ‘quartz‐enriched’ sand by means of selective grindings according to the different degrees of hardness and cleavage of the mineralogical phases. Melting experiments, carried out on treated sand and in the temperature range compatible with Roman technology, yielded a glass with composition similar to those of typical Roman glasses. Therefore, new perspectives on the sources of supply of raw materials, hitherto debated, are opened up.     

AFTERWORDS: AN INTRODUCTION TO ARTHUR DANTO'S PHILOSOPHIES OF HISTORY AND ART*

This essay is written as an introductory essay to celebrate the third edition of Arthur Danto's Analytical Philosophy of History, first printed in 1965. It raises questions about what it means to write an introduction and whether it is possible to write an introduction‐given Danto's own philosophical theses on history, the essay pays special attention to the connections between Danto's philosophy of history, philosophy of art, and the other areas of his philosophy that he regards to be all of a piece. It considers the nature of analytical philosophy and its heyday in America in the postwar period, when, to some degree, it was used as an antidote to an ideology of history that had perverted some of the most influential claims in a philosophy of history developed in Germany (mostly by Hegel) around 1800.     

X-RAY MICROANALYSIS OF ANCIENT GLASSY MATERIALS: A COMPARATIVE STUDY OF WAVELENGTH DISPERSIVE AND ENERGY DISPERSIVE TECHNIQUES*

Sensitivity, precision and accuracy of quantitative microanalysis of major, minor and trace elements present in ancient glasses by energy dispersive spectrometry (EDS) is compared to that by wavelength dispersive spectrometry (WDS). Although there are certain problems with EDS due to peak overlaps and background noise, the precision and minimum detection limits of EDS for most of the important elements in ancient glasses were found to compare favourably to those of WDS. Both EDS and WDS, when quantified by comparison to glass standards, can produce reliable results which are adequate for most technological questions.     

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.     

CAVES AND GEOPHYSICS: AN APPROXIMATION TO THE UNDERWORLD OF TEOTIHUACAN,MEXICO*

This article describes the result of a geophysical survey in the vicinity of the most important construction of the ancient Prehispanic urban centre of Teotihuacan, Mexico. The survey was intended to locate a system of tunnels under the city. It is proposed that the system was originally dug to obtain construction materials, but afterwards it was used for ideological needs.     

HUMAN SPACE, TERRITORIALITY, AND CONFLICT: AN EXPLORATORY STUDY WITH SPECIAL REFERENCE TO ISRAEL AND THE WEST BANK

This brief and speculative paper focuses direct attention on Totem, in particular certain totemic concerns with space as place. Through adopting an overall structuralist perspective, Eretz Yisrael, the land of Israel, is considered as a totemic space. This is developed against the broader backcloth of Jewish societal development and advanced through a brief study of the continuing Jewish settlement of Samaria. It is suggested that no deeper comprehension of the proceeding settlement initiatives is attainable unless the importance of such a perspective is realized. The brief review, short case study, and pointers to proceeding work provide crucial subjects for further attention. The contentious, indeed emotive, nature of the paper is to be emphasized     

QUICK ESTIMATES OF SOFT SEDIMENT THICKNESSES FROM AMBIENT NOISE HORIZONTAL TO VERTICAL SPECTRAL RATIOS: A CASE STUDY IN SOUTHERN ITALY

An approach devoted to quickly assess the thickness of soft sedimentary cover in areas of unknown subsurface morphology is applied in this study. In particular, soil thickness (h) is derived by combining estimates of the resonance frequency (f _r ) relative to soft sediments with the local shear-wave velocity (V_s) profile. For this purpose, (f _r ) values are assessed from horizontal to vertical (H/V) spectral ratios of seismic noise recordings and the (V _s ) profile is obtained by considering information from shallow seismic surveys. Results obtained for a Quaternary sedimentary basin in Southern Italy are discussed. Since in the investigated area only weak independent constraints are available, special emphasis is given to the assessment of uncertainties involved in this estimate of soil thickness.     

FROM VIOLENCE TO RECONSTRUCTION: THE MAKING, DISINTEGRATION AND REMAKING OF AN APARTHEID CITY

This article analyzes the relationship between violence and the racial city. It examines Durban's construction and disintegration in the context of unsuccessful apartheid reform, and traces corresponding distinct but overlapping stages of violence. Internecine violence of the latter 1980s constituted a racially displaced confrontation over political control and resources of the society transformed into internecine conflict within black residential areas, especially the urban peripheries. The violence was rooted in spatial and material differentiation reinforced by township and shantytown power structures, which clandestine state intervention accentuated. The article concludes by analyzing the new spatial and racial city forms, suggesting alternative urban reconstruction paths to redress the deeper causes of violence.     

WORKING-CLASS WOMEN AND CIVIC ACTION: A CASE STUDY OF AN INNOVATIVE COMMUNITY ROLE*

This paper focuses on working-class women who are assuming public responsibility in voluntary organizations aimed at the maintenance and improvement of their city neighborhoods. Forty women were interviewed in-depth regarding their civic concerns and voluntary activities in a case study of Carondelet, a predominantly white working-class neighborhood of St. Louis. Overall, activism is well-organized and widespread with women playing a major contributing role. If the experience of Carondelet is typical, then future urban policy analysis must seriously take into account extensive female input at the grass-roots level.     

THE TIME OF POLITICS,THE POLITICS OF TIME,AND POLITICIZED TIME: AN INTRODUCTION TO CHRONOPOLITICS

Time is so deeply interwoven with all aspects of politics that its centrality to the political is frequently overlooked. For one, politics has its own times and rhythms. Secondly, time can be an object and an instrument of politics. Thirdly, temporal attributes are used not only to differentiate basic political principles but also to legitimize or delegitimize politics. Finally, politics aims at realizing futures in the present or preventing them from materializing. Consequently, the relationship between politics and time encompasses a broad spectrum of phenomena and processes that cry out for historicization. In our introduction to this History and Theory theme issue on chronopolitics, we argue that the concept of chronopolitics makes it possible to do this and, in the process, to move the operation of rethinking historical temporalities from the periphery toward the center of historiographical attention as well as to engage in a dialogue with scholars from a wide range of disciplines. To this end, we propose a broad concept of chronopolitics by discussing existing definitions, by distinguishing between three central dimensions of chronopolitics (the time of politics, the politics of time, and politicized time), and by systematizing possible approaches to studying chronopolitics.     

CALCULATING THE COST OF TRANSFERRING STUDENTS FROM PAROCHIAL TO PUBLIC SCHOOLS: AN EXAMINATION AND CRITIQUE

Public sector aid to K-12 parochial schools is often justified on the basis that providing assistance is cheaper than having to absorb all those students into public school systems. But is it? The cost of transferring students from parochial to public K-12 schools has never been satisfactorily calculated. This article points to the weaknesses in previous efforts and outlines the elements that must be present in a comprehensive estimate of transfer costs.     

"WHEN THE GREAT PLANES CAME AND MADE ASHES OF OUR CITY …"1: TOWARDS AN ORAL GEOGRAPHY OF THE DISASTERS OF WAR.

This paper reconstructs a view of armed violence from the personal testimony of civilians who survived massive bombing of their neighborhoods. A majority of raid victims are “ordinary” civilians, primarily women, children, and the elderly. In World War II the most destructive city-wrecking campaigns were directed against the “morale” of these civilians. Their concerns and experience receive little consideration in the literature of air war, yet huge wartime and postwar surveys recorded first hand testimonies of those in heavily bombed cities in Germany, Japan and England. Women's words are given priority: they represent the majority of able-bodied persons under the bombs, and bear witness to the human ecology of violent experience: the disruptions of everyday life; the worlds of blackout and underground; the losses of home places and urban culture. They testify as well to the uneven social and spatial distribution of harm within cities, where death, damage and homelessness overwhelmingly affected working class and inner city areas. The paper also suggests that personal testimony should be recovered and incorporated into studies of neglected and disadvantaged people in “oral geography.” Some of the radical departures and methodological rethinking involved are considered in a final section.     

COOKING AND PAINTED WARE FROM SAN GIUSTO (LUCERA,FOGGIA): THE PRODUCTION CYCLE,FROM THE SUPPLY OF RAW MATERIALS TO THE COMMERCIALIZATION OF PRODUCTS*

Archaeological excavation at the San Giusto site (Lucera, Italy) has unearthed a Late Antique kiln that was most certainly dedicated to the production of cooking ware. An archaeometric study of numerous specimens of cooking and painted ware found at this site was carried out using optical microscopy, scanning electron microscopy, micro‐Raman spectroscopy, X‐ray diffraction, X‐ray fluorescence, inductively coupled plasma mass and optical emission spectrometry and instrumental neutron activation analysis. The integration of historical–archaeological data with archaeometric data has revealed that these specimens can be attributed to the San Giusto site. Furthermore, the production cycle of this ware can thus be reconstructed: from the diversified supply of raw materials (fluvial and marine sediments), to the relatively complex preparation of the paste, to firing at variable temperatures (600–750°C for cooking ware; 850–1050°C for painted ware).     

LEAD ISOTOPE ANALYSES OF BRONZE AGE COPPER‐BASE ARTEFACTS FROM AL‐MIDAMMAN,YEMEN: TOWARDS THE IDENTIFICATION OF AN INDIGENOUS METAL PRODUCTION AND EXCHANGE SYSTEM IN THE SOUTHERN RED SEA REGION*

The results of the lead isotope analysis (LIA) of 15 copper‐base artefacts from the Bronze Age site of al‐Midamman, Yemen, are reported. The LIA data suggest the existence of an indigenous Bronze Age metal production and exchange system centred on the southern Red Sea region, distinct from those in neighbouring regions of Arabia and the Levant. These preliminary results are highly significant for the archaeology of the region, suggesting that local prehistoric copper extraction sites have thus far gone unrecorded, and highlighting the need for systematic archaeometallurgical fieldwork programmes in the countries surrounding the southern Red Sea.
