THE USE OF ROMAN COINAGE

Summary. There is little doubt that Roman coins found today in excavations were lost during the Roman period because they were in use. If these coin-finds are examined in the appropriate way it should be possible to detect something of the patterns of coin-use and coin-loss in the ancient world and hence to learn something of the monetary side of trade and the economy. Finds from different sites are compared in an effort to establish basic rules of interpretation, or, failing that, of presentation of the evidence.     

A CHARACTERIZATION OF THE COMPOSITIONAL VARIATIONS OF ROMAN SAMIAN POTTERY MANUFACTURED AT THE LEZOUX PRODUCTION CENTRE

The study addresses the chemical variations for Roman Samian wares manufactured during various periods at different workshops within the Lezoux production centre. Instrumental neutron activation analysis and inductively coupled plasma spectrometry were used to determine the chemical constituents of the pottery. The two techniques were evaluated based on the capacity of each to identify the same compositional groups for Lezoux Samian with the use of multivariate statistics. The compositional analysis redefines and clarifies how potters used the clay sources at the site to produce fine wares. The results indicate that the majority of potters from different workshops at Lezoux shared the same clay source during the second century AD.     

CHARACTERIZATION OF SAMIAN WARE SHERDS BY MEANS OF NEUTRON ACTIVATION ANALYSIS

Neutron activation analysis has been employed for the characterization of Samian ware sherds. The analysed samples were classified in ten groups, seven of which belonged to the Arretine production, according to archaeological evidence. By means of high resolution gamma-ray spectroscopy, 22 elements have been identified and analysed. Compositional characterization was looked for by taking counting rate ratios of different nuclides in the samples. The compositional pattern of the sherds was found to be fairly uniform both for each pot and for each group so that, at least in the examined cases, it can be assumed to be characteristic of a given workshop.     

REIMAGINING ROMAN PORTS AND HARBOURS: THE PORT OF ROMAN LONDON AND WATERFRONT ARCHAEOLOGY

This paper explores some theoretically informed ways in which to use the rich evidence relating to ports, harbours and other waterfront installations in archaeology. It argues that studies of waterfront structures within the specialisms of nautical/maritime and wetland archaeology are extremely important in their own right, but they could also be used to explore broader issues connected with their use and context. These include the cultural and religious significance of water and its dangers, the symbolic significance of landscape change, the relationship between people and their environment and the negotiation of the land/water interface. Examining the evidence of the port of Roman London as a case study, this paper explores the archaeology in its local setting and addresses a number of subjects relating to both its temporal and spatial position. It focuses on the religious significance of water and the implications of altering waterscapes through artificial construction.     

NEUTRON ACTIVATION ANALYSIS OF ROMAN AFRICAN RED SLIP WARE KILNS

Roman African Red Slip ware (ARS) sherds from four ARS kiln sites in modern-day Tunisia (El Mahrine, El Ala, Oudna and Pheradi Maius) have been analysed using instrumental neutron activation analysis. Multivariate statistical methods (including cluster analysis and Manhattan City Block distances), with a dilution correction applied to the data, were used to interpret the concentration data. Reference groups for each of the four kiln sites were established. Both El Mahrine and Oudna were described by two dilution-related groups. These kiln groups were all shown to be compositionally distinct from each other and suitable for use in provenance studies.     

THE ORIENTATION OF ROMAN CAMPS AND FORTS

Summary.   The angles of orientation of 67 Roman camps were determined from their published plans. There was a marked tendency for them to be aligned close to the cardinal points but they were offset from those points by only 28 of a possible 45 angles and of these six occurred in 29 camps, probably because they were set out by making right-angled triangles whose non-hypotenuse sides were in whole number ratios. Twenty-seven forts on the British frontier walls were similarly orientated by only 12 angles, one of which occurred six times. The apparent accuracy of the layouts suggested that the directions of the meridian and latitude were first carefully determined. The use of a limited number of offset angles was probably due to a religious regard for celestial geometry.     

PROVENANCE STUDIES OF ROMAN AFRICAN RED SLIP WARE USING NEUTRON ACTIVATION ANALYSIS

African Red Slip ware (ARS) from Carthage and San Sisto Vecchio (Rome) was analysed by neutron activation analysis. The Carthage tableware was linked with Oudna and the type 1 lamps were probably from a northern ARS/lamp factory other than the sources currently investigated. Two samples were central Tunisian, probably manufactured at El Ala. The San Sisto samples divided into three groups and three outliers of undetermined provenance. Group 1 was central Tunisian, probably from El Ala, and was composed entirely of terra sigillata chiara C forms. Group 2 was of unknown origin within northern Tunisia. Group 3 was the largest subset and most of its constituent samples were associated with El Mahrine. Additionally, four samples were linked with Oudna.     

THE PETROGRAPHY AND CHEMISTRY OF THIN‐WALLED WARE FROM AN HELLENISTIC– ROMAN SITE AT SEGESTA (SICILY)*

Samples of Roman thin‐walled ware from Segesta (northwestern Sicily), dating back to the early Imperial period, were studied by optical microscopy (OM) and Neutron Activation Analysis (NAA). Up to now, this class of Roman fine tableware has only occasionally been evaluated archaeometrically. Nevertheless, numerous production centres are believed to have been simultaneously active in the western Mediterranean area. Petrographic and chemical data seem to be in agreement with the archaeological hypothesis of local manufacture in Segesta for most of the analysed samples, through a comparison with kiln wasters and local raw materials. The effectiveness of thin‐section petrography for determining the provenance of such a tiny tempered class of pottery and the integrated use of two different grouping procedures (petrography and chemistry) were also tested.     

THE BIRDS OF ROMAN BRITAIN

Summary. Wild birds were probably of little importance for food in Roman Britain, but there is some advantage, for ecology, conservation, archaeological reconstruction and education, in establishing a tolerably correct list of species present in Roman times. There are special problems for the recovery and identification of bird bones; on the other hand, historical and other sources are wanting for Roman Britain. There is no evidence for falconry in the Roman period; birds would be caught, for sport by lime-rods, and for food by a variety of methods. There is little definite evidence for religious use of wild birds in Roman Britain. The environment of Britain in the Roman period was, in many respects, quite similar to that of recent times, but the bird species recorded from Roman sites suggest that the landscape was rather varied, and favourable to wildlife. An up-to-date list of 94 wild species can be roughly quantified by the number of sites on which each has been found; both the more numerous species and the absentees offer some surprises, and the effect is to emphasize the Romanization of eating habits in the province.     

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.     

OPPIDA AND THE ROMAN ARMY. A REVIEW OF RECENT EVIDENCE

Until recently it has been commonly assumed that the Roman army made relatively little use of pre-exising fortifications such as hillforts and oppida. The accumulation of evidence over the past twent years suggests that this view is to be modified. The informastion now available from Gaul, Germany and especially from southern Britain indicates that military use of prehistoric strongholds was widespread and probably far from rare, notably in he early phases of occupation. Such use might reflect political control in the case of large oppida like the Titelberg, Camulodunum and perhaps Maiden Castle, or the securing of supplies, or possibly on occasion the use of native levies.
