In this thesis, the fabrication technology of Roman lead glazes were examined using a number of materials science techniques: namely, electron probe microanalysis, X-ray diffraction, and inductively coupled plasma atomic emission spectroscopy. The overall aim of this work was to discern particular technological styles for a wide group of lead glazes by quantifying the chemical and microstructural features of glaze production. Using experimental replication, it was found that two basic methods of glazing could be identified chemically. When applying PbO alone to an earthenware ceramic, the resulting glaze was in equilibrium with the ceramic as indicated by flat compositional profiles obtained along the glaze cross-section. However, when applying PbO·SiO₂ mixtures to earthenware ceramics, gradient profiles indicative of diffusive mass transfer were obtained from the glaze cross-section. On the basis of these chemical criteria, these two methods of glazing were identified in archaeological material. It has been determined that the earliest lead glazes from Anatolia and Italy (approximately 1^st century B.C.) were made using PbO·SiO₂ mixtures applied to calcareous clays with Fe and Cu oxides added as colourants. Later production (post 2^nd century A.D.), seems to have employed PbO alone applied to non-calcareous clays with no intentionally added colourants. The Roman production of lead glazes was compared to both those of Late Antiquity (4^th – 10^th centuries A.D.) which continued to use PbO applied to non-calcareous clays, and to those of Byzantine and Islamic contexts (8^th – 14^th centuries A.D.) which seem to have used PbO·SiO₂ mixtures applied to both calcareous and non-calcareous clays. It is also argued that the technological features of the Byzantine and Islamic glaze production shared more in common with the contemporary Chinese lead glazing tradition (the Sancai wares of the 7^th century A.D.) which also used PbO·SiO₂ mixtures applied to non-calcareous clays, than with the Late Antique glazing tradition.

This study has attempted to examine third and fourth century pottery supply in northern England together with other aspects of pottery assemblages in the region. The pottery kilns of the East Yorkshire industries have been characterised by neutron activation analysis which has proved reasonably successful in discriminating between them. Neutron activation analysis has also been utilised to attempt to check visually identified fabric groups and to help isolate other fabrics. This has been of varying success. Quantified data has been collected from 15 sites across the north and the limited published quantitative data have been utilised to examine the distribution, marketing and competition between fabric types in the region. Examination of functional variations through time between different types of site has also been undertaken as has that of variations in the quantity of finewares through time and between different types of site together with an attempt at quantifying decoration and examining trends in this. Pottery supply to the northern frontier area would seem to have been organised by different mechanisms in different periods. In the second century much of the pottery used on the frontier would appear to have been produced by the military themselves whilst in the third century and earlier fourth century free market mechanisms would seem to have operated, but in the late fourth-early fifth centuries some form of 'military contract' would appear to have taken over supply. Functional variations between different types of site have been identified with rural sites, turrets and Signal Stations sharing a major emphasis on the jar as the basic ceramic form and more complex settlement types having more diversified functional groups. The distribution of finewares also seems to be concentrated on more complex settlement types. It is apparent that there are consistent differences between the East Yorkshire region and the rest of the study area which may well reflect differences extending back into the Iron Age. Similarly there seem to be indications of some 'de-Romanisation' in late Roman assemblages but this does not develop in the fifth century, when nearly all the strands of evidence of Romano-British material culture disappear very rapidly.

Three pottery assemblages from the Yambol District were processed in this thesis to enrich our knowledge about the Roman and Late Antique pottery material in Ancient Thrace. The first, and most abundant assemblage, is from the Roman vicus called Yurta, which is located near the village of Stroyno and dated from the 1st /2nd c. AD till the Late Antiquity. This assemblage is substituted by different pottery classes which give us bases for identifying the variability of the pottery material and the different wares and fabrics in the area. In addition, it represents the main material for statistics and for a quantitative comparison of individual classes. The second assemblage includes 19 complete vessels from two burial mounds in Palauzovo, dated to the 2nd -3rd c. AD, and gives a comparative sample for the settlement contexts as well as a basis for studying the ways in which pottery was modified for special burial purposes. The last set of 57 vessels comes from a closed context dated to the end of the 6th c. AD, which was found in a collapsed house at the Dodoparon hillfort, rising above the village of Golyam Manastir. It represents a unique set of finds from the Late Antiquity, which is well dated and preserved. The three pottery assemblages are all different, each with a distinct character, which...

L’any 1959 en Federico Foerster Laures, submarinista soci del CRIS (Centro de Recuperaciones i Investigaciones Submarinas), enviava una carta al Dr. Oliva, cap de l’arqueologia gironina i director del Museo Arqueológico Provincial de Girona, on li notificava la descoberta, a les aigües del Massís del Montgrí, d’un derelicte amb una gran quantitat de plats, que podrien de ser de gran interès per la realització d’un estudi arqueològic. Aquí va començar un treball que es perllongà fins l’any 1970 i que ha donat peu a diferents publicacions i estudis, a vegades contradictoris, sobre el jaciment que es coneix amb el nom d’Illa Pedrosa. Aquesta tesi doctoral que presentem és un estudi aprofundit del carregament que transportava el derelicte d’Illa Pedrosa en el moment del seu enfonsament. Aquest jaciment subaquàtic excavat per F. Foerster entre els anys 1959 i 1970, tot i que la direcció científica correspongué al Dr. Oliva, es pot considerar el primer derelicte excavat amb una metodologia amb intenció científica a les costes catalanes (Foerster 1975, 114). Els estudis preliminars del carregament del jaciment li donaven una cronologia al voltant de l’inici del segle I aC (Foerster 1975). Posteriorment altres autors li han donat cronologies més detallades i més antigues, com Morel, el qual el situà entre el el 150-140 aC. (Morel 1981, 63) o bé Sanmartí que l’inclou entre el 140-130 aC. (Sanmartí 1985, 155). Fins i tot hi ha autors que han vist en aquest jaciment una superposició de vaixells de diverses cronologies (Roman 1987). Aquestes divergències posen de manifest la necessitat d’un estudi aprofundit del derelicte, així com una revisió a fons dels seus materials. / Illa Pedrosa was a small ship, 10-12 meters length, with a heterogeneous cargo, that was doing some redistribution trade around Empúries and sunk in 140-130 b.C. The study of the shipment remains, especially the Campanian A ceramic and italic amphorae, it can be established that the ship departure from Empúries and made a north-south route. The results of the study of Illa Pedrosa wreck, together with the comparative analyses of other contemporaneous sites, especially those geographically close to it, such as Cala Galladera (Cadaqués, Alt Empordà) and Aiguablava VI (Begur, Baix Empordà), it can be establish a model about the organization of maritime trade in Northeastern Peninsula. These heterogeneous shipments, id est different products from different origins, are characteristics of the navigation return towards the secondary ports. This situation is explained by the theory of the redistribution trade between principal and secondary ports (Nieto 1988, Nieto et al. 1989). The costal navigation from the secondary ports supplied the main ports with homogeneous shipments. In contrast to this situation, the trips of return were adapted to the demands of the secondary ports, in particular related to the products that they can find stored in the main ports. This coastal navigation was an integral part of a large-scale redistribution from other main ports. The infrastructure of each main port was also used to the small-scale distribution of products between some secondary ports, which were located in the limits of their hinterland. The information provided by the study of Isla Pedrosa allows to developing the theory Illa Pedrosa of X. Nieto about the redistribution of products and maritime trade between the main and secondary ports (Nieto 1988, Nieto et al. 1989).

Entre los siglos II-III d.C. la ciudad de Carthago Noua (Cartagena, España) conoce una serie de transformaciones que alteran su paisaje urbano, su extensión se reduce a la mitad y numerosos edificios públicos y privados son abandonados. En este trabajo se estudia la evolución de la ciudad entre el Alto y el Bajo Imperio a través del análisis de la cultura material cerámica. Siete contextos de la colonia y su entorno son estudiados de manera total, incluyendo todas las producciones (cerámicas finas, ánforas, cerámica común, lucernas...) desde época tardo Antonina hasta el gobierno del emperador Diocleciano. / Between the second and third centuries A.D. the city of Carthago Noua (Cartagena, Spain) meets a series of changes that alter the urban landscape, reducing its size in half and drop-populating numerous public and private buildings. In this work we studied the evolution of the city between Early and Late Empire through the analysis of ceramic material culture. Seven contexts of the colony and its hinterland are studied in whole, including all productions (fine wares, amphorae, coarse wares, lamps ...) from the time of the last Antonine emperors until the reign of Diocletian.

Cette étude analyse les céramiques communes romaines provenant de la cité de Cumes (Naples, Campanie) sur un arc temporel très étendu, depuis le IIe siècle av. J.-C. jusqu’à l’abandon du site durant l’Antiquité tardive. Après avoir examiné les données disponibles sur la production et la circulation des céramiques dans cette région de la baie de Naples, on analyse les mobiliers inédits des fouilles dans le forum, conduites par l’Università degli Studi di Napoli « Federico II », dans le cadre du projet Kyme, un programme de recherche et de mise en valeur des vestiges de la ville antique avec la participation de deux universités napolitaines et du Centre Jean Bérard (CNRS). Les données recueillies sur le site par les diverses équipes clarifient le rôle de Cumes comme centre de production céramique. Certaines céramiques communes fabriquées par les potiers de la ville connaissent une très large diffusion et sont parmi les productions les mieux attestées dans tout l’Empire romain: c’est le cas de la céramique dite à engobe rouge pompéien (ceramica a vernice rossa interna, Pompeian Red Ware o Pompejanisch-rote Platte). Les caractéristiques spécifiques du site et de l’assemblage de céramique commune étudié ont encouragé à adopter pour ce travail un système de classification différent de celui utilisé pour les productions communes de la Campanie jusqu'à présent. Chaque type est illustré analytiquement, avec le support d’une large documentation graphique et, dans la plupart des cas, des données fournies par l’étude des lames minces. L’examen des mobiliers provenant des fouilles du forum de Cumes et le réexamen des vases attestés dans la ville et en dehors du site, ont permis la révision des connaissances antérieures sur la production et la chronologie des types, en les confirmant ou en les modifiant. La documentation recueillie permet de dégager le cadre complexe de la production de céramique commune à Cumes. En outre, l’étude des importations a fourni nouveaux éléments sur les échanges commerciaux atteignant le site et la région phlégréenne, très influencés par la présence du port de Puteoli, porte de Rome sur les provinces de l’Afrique e de l’Orient. En examinant les variations du répertoire des formes représentées et les pourcentages des céramiques communes locales par rapport aux autres productions de l’Empire au cours des siècles, il a été possible d’observer des changements dans les flux commerciaux et dans les habitudes des individus. Il s’agit d’élever le regard des objets quotidiens pour atteindre les changements sociaux et économiques intéressant le site et le Champs Phlégréens entre le Haut Empire et l’Antiquité tardive. / This study analyzes Roman Coarse Wares from the city of Cumae (Naples, Campania), over an extended period, from the II century B.C. to the abandonment of the site in the late Antiquity. After examining the available data on pottery production and circulation in this area of the bay of Naples, the unpublished assemblages from the forum are analysed. These contexts were found during the excavations carried out by the Università degli Studi di Napoli “Federico II”, in the framework of the Kyme Project, in which two Neapolitan universities and the Centre Jean Bérard (CNRS) are involved to promote the research and the valorisation of the ancient city. New data sets collected by these different teams highlight the role of Cumae in pottery production. Some coarse wares produced in Cumae were widely traded across the entire Roman Empire, in particular the so called Pompeian Red Ware (ceramica a vernice rossa interna, céramique à engobe rouge pompéien or Pompejanisch-rote Platte). The characteristics of the site and of the coarse ware assemblages led to the adoption of a classification system fundamentally different from those used in studies on Coarse Wares made in Campania until now. Every type of pottery is analytically described and illustrated, with profile drawings and, in most cases, with the support of data provided by thin-section study. The examination of Coarse Wares discovered in the excavations of the forum of Cumae and the re-examination of available documentation about Coarse Wares finds from the city and elsewhere, leads to review our previous knowledge about the chronology of each type and production, confirming or modifying them. The collected documentation allows us to reconstruct the framework of Coarse Wares production in Cumae. Furthermore, the study of imported Coarse Wares from the forum of Cumae provided new clues for reconstructing trade evolutions in the city and in the Phlegraean Fields, strongly influenced by the vicinity of the port of Puteoli, gateway of the Roman provinces of Africa and the Eastern Mediterranean. Examining forms evolutions and their percentage of the local and imported production through centuries, we observe changes in trade and in individuals habits and how everyday objects give insights on social and economical changes at Cumae and in the Phlegraean Fields during the Early Roman Empire and the late Antiquity.
