This thesis is contains descriptions and definitions of the 2nd millennium BC tholos tomb architecture in Mainland Greece. The study area is divided into eight regions: Peloponnessos, Central Greece, Epirus, Attica, Euboea, Thessaly, Macedonia and Thrace. The time period of earliest tomb dated between 2000-1675 BC and the latest between 1320-1160 BC. Attention has been put on issues of typological characteristics, construction technique and stone materials of the tholos tombs.

Samples from nearly 800 Bronze Age pottery sherds from Euboea, Eastern Boeotia and Eastern Thessaly were analysed together with 9 raw clays from the same areas. The-analysis was carried out in an attempt to identify areas of pottery manufacture, to discover the origin of specific groups of pottery, to relate pottery to, raw clays and to see how far pottery compositions can be associated with, and predicted by, geology. The work was done on the same lines as earlier studies at the Oxford Laboratory and at the British School at Athens. The main analytical technique used was therefore optical emission spectroscopy. Some 25% of the total number of sherds were also analysed by atomic absorption spectrophotometry so that the results obtained by the two techniques could be compared. The interpretation of the results was facilitated by the use of, computer program packages for cluster and discriminant analysis. Both optical emission and atomic absorption analysis resulted in broadly similar groupings although the absolute concentrations were not directly comparable. The groupings obtained after atomic absorption analysis had the narrower concentration ranges. Nine elements were measured by both techniques but in atomic absorption potassium was added and proved; useful as an additional discriminant. Six composition groups were distinguished from the data. One of them was identified as Euboean, 2 as Boeotian and 3 as coming from different regions of Thessaly. The greatest movement of pottery within these areas was from Euboea to Thessaly. No composition group which originated from outside these regions was identified. Six of the 9 raw clays were associated with the prevailing composition group in the area from which they came. It was not possible to predict trends in pottery composition by examination of the local geology.

Les figurines néolithiques de la Thessalie est un sujet très débattu. Dans le cadre d'une recherche fortement focalisée sur les qualités morphologiques des figurines, nous considérons indispensable d'aborder un aspect constamment négligé, à savoir leur fabrication. Fondée sur les principes de la technologie culturelle, notre étude vise non seulement à reconstituer les processus techniques de la fabrication des figurines néolithiques depuis la préparation des matières premières, jusqu'au produit fini, mais aussi de repenser les connotations imaginaires du déroulement de ces procédés et de considérer leurs implications culturelles multiples. En utilisant l'outil analytique de la chaîne opératoire, nous avons entrepris une étude technologique des figurines provenant de différents sites en Thessalie, afin de reconstituer le processus de leur fabrication. L'identification des chaînes opératoires particulières nous a permis de circonscrire la physionomie de la production idoloplastique et d'aborder, dans un deuxième temps, la fonction des figurines. Considérant que la fabrication fait partie intégrante de la fonction, nous avons jugé indispensable de nous tourner vers l'ethnologie, afin de nous procurer des exemples qui pourraient servir de références susceptibles d'éclairer nos données archéologiques. Deux enquêtes ethnographiques dans l'Anti-Atlas marocain et le recours à l'expérience anthropologique nous ont permis d'éclairer l'organisation de la production des figurines néolithiques de la Thessalie et leurs fonctions possibles. / The neolithic figurines of Thessaly is a subject that has sparkled many debates. In the context of a research strongly focused on the morphological qualities of the figurines we consider it essential, to address a constantly neglected aspect, their manufacture. Based on the principles of cultural technology, our aim is not only to identify the technical processes involved in the manufacture of neolithic figurines, from the preparation of the raw materials to the finished product, but also to rethink the imaginary connotations of these processes and to consider their multiple cultural implications. Using the analytical tool of the chaîne opératoire, we undertook a technological study of figurines from different sites in Thessaly, in order to reconstruct the processes of manufacture. The identification of the particular chaînes opératoires allowed us to circumscribe the physiognomy of idoloplastic production and then to address the question of the function of the figurines. Considering that manufacturing is an integral part of the function, we considered it indispensable to turn to ethnology, in order to obtain examples that could serve as references and thus help us to interpret the archaeological data. Two ethnographic surveys in the Moroccan Anti-Atlas and the appeal to the anthropological experience, have allowed us to reconstruct the organization of the production of neolithic figurines of Thessaly and their possible functions.

The history of central Greece in the fourth century BC has long been viewed through the lens of Athenian and Spartan interests which distorts the historical narrative and often misleads the reader regarding the causes and effects of events in this region. The following examination rejects this view and instead uses a regional approach to achieve new and unique understandings of major events in central Greece during the first half of the fourth century BC. The main focus of the examination is the internal developments of the Boeotian League and its interaction with the other states of central Greece. This refers to the relationship between Thebes and the other cities of Boeotia within the federal state as well as between the Boeotian League and Locris, Phocis, and Thessaly. These relationships, when assessed from a regional perspective using both literary and archaeological evidence, craft a new narrative for the political and military history of central Greece, a narrative which can be defined as ‘Boeotian.' In doing so, many long-standing ideas regarding this period will be challenged including ideological shifts within the government of Boeotia, motivations for the beginning of the Corinthian War, the historical importance of Pelopidas and Epaminondas, and the mechanisms of Boeotian supremacy in central Greece.

In this framework, eighty (80) thematic maps have been produced using Geographic Information Systems. In addition, many tables, drawings, cartographic or statistical diagrams have been created. Moreover, a large number of photographs are also presented. The engineering-geological framework of the basin is given in detail, based on the analysis and composition of collected data, regarding, specifically, the geomorphological and hydrometeorological conditions, the seismicity and seismic hazard, the lithological characteristics and structure of the geological formations, the hydrogeological conditions, as well as the weathering and erosion processes exhibited in the geological formations that occur in the basin. Furthermore, an engineering-geological map of the Western Thessaly basin at a scale of 1:100,000 has been compiled, aiming to facilitate both urban planning and industrial development of the basin’s wider area. It is considered that this map may well contribute to the optimization of land use planning and improve the allocation and planning of civil engineering projects. The formations encountered in the basin are grouped into twenty three (23) engineering-geological unities, with regard to their geotechnical behaviour. The entire study, engaged to this thesis, was basically based on data from both in situ investigations and geotechnical information derived and evaluated from the utilisation of 1,039 existing boreholes and trial pits, in the plain part of the Western Thessaly basin. Totally 22,463 records were created and allocated in six (6) Tables. In each one of these tables different kind of geo-information were stored. The values of the above parameters were critically examined. Besides, statistical analysis was carried out on Standard Penetration and Permeability Tests result. All the geotechnical characteristics of the Quaternary deposits (physical properties and mechanical parameters) have been analyzed and a Geotechnical Database was created and presented in this thesis. Furthermore, a landslide inventory map of the Western Thessaly basin has been compiled. Many technical reports and studies, which refer to landslide occurrences, mainly obtained from the Institute of Geology and Mineral Exploration (IGME) were used to analyse and record all the landslides of the study area. A Database, using Microsoft Access, has been compiled. The connection between the Database system and Geographic Information Systems was established with the defined coordinates of the locations of existing landslide occurrences. After the necessary modifications, 979 landslide events were recorded and digitally stored. Also, a simple statistical evaluation of the available recordings was applied for the assessment of the engineering-geological data regarding the lithology and geomechanical characteristics of the encountered various geo-materials. Finally, the surface subsidence ruptures manifested in the basin’s area have been investigated.

This thesis presents a first archaeological introduction to the study of Byzantine ports, harbours and other coastal installations in the region of Thessaly. Thessaly not only constitutes an ideal region to gain equal information for the Early- to the Late Byzantine periods, but also to compare independent regional and imperial central building activities. However, in particular Thessaly’s maritime connectivity has never been studied in detail before. As such, a first step into a terra incognita, the thesis is divided into two main sections: In order to conceptualize the study of harbour sites, the thesis first sets up a framework for the definition, understanding and interpretation of the physical features of harbours and their function and purpose. Taking into account influencing environmental conditions, such as natural, economic, social and political components, this helps to determine an accurate hierarchical model and to illustrate the interrelationship between different types and forms of harbour sites. Subsequently, comprehensive archaeological investigations around the island of Skiathos and other harbour sites in Thessaly, executed in 2012 and 2013, are set against this theoretical groundwork. In contrast to the common approach of regional studies, where a first general overview is followed by individual detailed case-studies, the opposite methodology is undertaken in order to achieve a systematic study of the Thessalian harbours and the complexity of their network system. Consequently, the collection of data starts from the analysis of a distinct area of a region and continues with the broader regional picture of primary ports, secondary harbours and staple markets. Functioning as an important junction of the Aegean shipping lanes and being involved in regional as well as supra-regional trade and port networks, focus is therefore primarily dedicated to the island of Skiathos. A joint survey project in cooperation with the Greek Ephorate for Underwater Antiquities (EEA), the 13th Greek Ephorate for Prehistoric and Classical Antiquities and the 7th Greek Ephorate for Byzantine Antiquities was initiated by the author in 2012. A number of sites, including harbour installations and other coastal infrastructures, have been detected, documented and subsequently verified by geophysical prospections, using a Sub-bottom profiler and Side-Scan Sonar, in 2013. These have allowed to draw a clear historical picture of architectural developments, port networks and changes in the socio-economic connectivity of the area. Followed by a close investigation of further harbour sites throughout the entire region of Thessaly during two field seasons between 2012 and 2013, the detailed picture gained from the Skiathos survey project is brought to a wider context. This comparison finally allows an overall picture of the history and architectural developments of harbour structures and associated coastal sites, as well as general conclusions concerning the hierarchy and port network in the region during the Early to Late Byzantine periods. This has allowed a comprehensive understanding of the growth, use and decline of various ports, harbours and staple markets within Thessaly and has important repercussions for our understanding of wider social and economic changes that were occurring during these periods, such as the rise of the church as a powerful economic institution or the increasing activities of private entrepreneurs. In this way the submerged maritime heritage of Thessaly has provided a rich new resource with which to understand the cultural dynamics of the region as it emerged from its peripheral location to comprising major ports within the Roman maritime network and to stand out of the heart of the commercial route ways to and from Constantinople, as well as being part of the emergent networks of the western maritime states at the end of the period, such as Venice.
