yes / Introduction: The 12th International Conference of Archaeological Prospection saw a return to the University of Bradford, the host for the 1st ICAP conference in 1995. Much has changed in the world of archaeological prospection since that inaugural event, but many things have also remained constant. Perusing the abstract list from the 1st conference reveals that there no less than 6 presenters who returned to present, and many more of the initial group returned to attend, at this, the 12th conference. For the 12th International Conference of Archaeological Prospection a number of key themes were targeted, divided in to six conference sessions: • Techniques and new technological developments • Applications and reconstructing landscapes and urban environments • Integration of techniques and inter-disciplinarity, with focus on visualisation and interpretation • Marine, inter-tidal and wetland prospection techniques and applications • Low altitude prospection techniques and applications • Commercial archaeological prospection in the contemporary world Many of the presentations in the Techniques and technological developments session highlighted the use of automated process in the filtering and recognition of data, and also the use of vehicles for the rapid capture of high resolution data. The Applications and reconstruction of landscapes and urban environments session highlighted contemporary research in a wide range of locations and temporal settings from around the world, from Stonehenge to Mexico, and from Northern Plains earthlodges to 19th century landscape gardens. The variety of presentations amply demonstrates the applicability of prospection techniques to a wide range of situations and purposes, and highlights the expansion seen in archaeological prospection since the 1st ICAP conference in 1995. Within the integration of techniques and visualisation session a number of presentations detailed the use of simultaneous data capture, and how such techniques have been integrated with specific research programmes to enhance the understanding of archaeological sites. The special sessions on Marine, inter-tidal and wetland prospection and Low altitude prospection for cussed on new and emerging technologies broadening the horizon for archaeological prospection. The use of underwater vehicles and aerial vehicles for data capture in the form of marine seismic data and LiDAR is detailed through a number of case studies. These demonstrate the novel use of emerging technologies for archaeological prospection, and the success of these applications will certainly lead to the growth of this field within coming years. A special session on commercial archaeological prospection combined a number of presentations from commercial practitioners in the field with a workshop session covering a range of key issues and standards relating to practices within both commercial and research archaeological prospection. The success of the 12th International Conference of Archaeological Prospection is due to both the presenting contributors and attending delegates. We also recognise the effort made by both the Organising Committe and Scientific committee, and thank the members for their dedication in organising the event, and for the prompt review and comments on all of the scientific papers. On behlaf of both the ICAP 2017 Organising Committee and the Scientific Committee we extend sincerest thanks to all of the presenters and attendees at the conference, and very much look forward to the 13th conference in 2019.

Yes / Since 2010 the Stonehenge Hidden Landscapes Project (SHLP) has undertaken extensive archaeological prospection across much of the landscape surrounding Stonehenge. These remote sensing and geophysical surveys have revealed a significant number of new sites and landscape features whilst providing new information on many previously known monuments. The project goal to integrate multimethod mapping over large areas of the landscape has also provided opportunities to re-interpret the landscape context of individual monuments and, in the case of the major henge at Durrington Walls, to generate novel insights into the structure and sequence of a monument which has attracted considerable research attention over many decades. This paper outlines the recent work of the SHLP and the results of survey at Durrington Walls that shed new light on this enigmatic monument including a site ‘hidden’ within the monument.

The Schlumberger array, or Schlumberger, was one of the first resistance arrays to be used to detect buried archaeological features. The early work used fixed probes and widely spaced traverses. Recent simulation work, ýhowever, suggested that the array should give improved resolution and depth penetration over the Twin-Probe array. This thesis is an attempt to operationalise the Schlumberger for use in archaeological prospection. This has been achieved via a co-ordinated use of laboratory simulation and-field studies. Initial fieldwork in England suggested. that the. - use of point electrodes created response patterns that were dependent upon the relative direction of linear targets. This was verified using a simulation tank modified to represent field procedure. The recognition of this response, therefore, required each survey area to be surveyed twice. The re-survey requires the two current probes to be positioned at right angles to the original survey points. The Schlumberger was then used in a battery of methods to investigate the problem of the archaeological interpretation of- small, discrete scatters of ceramic sherds that cover the landscape in Greece. The research has indicated a variation of intra-site patterning that may be significant to the function of these sites. Overall, the results suggest that the relationship between the 'site' and its environment is a complex one, one that can be oversimplified when the ceramic evidence is viewed in isolation. The Schlumberger indicated possible structural elements within some of these sites.

No / In archaeological prospection, computer processing is essential for all stages of data manipulation. This article investigates the contributions which informatics has made in the past and looks at its potential for the future. It is shown how the workflow of satellite imagery, aerial photography and geophysical prospection can be broken down into measurements, acquisition, processing, visualisation and interpretation. Based on these categories, the advantages of digital data manipulations are explored with individual examples. It is shown that informatics can greatly assist with the final archaeological analysis of the measurements but that human experience and assessments are crucial for a meaningful interpretation.

The aim of this thesis has been to investigate and interpret late Iron Ageand Early Medieval traces of non-ferrous metalworking on the islandGotland, Sweden. Gotland was not, based on the archaeological record, anintegrated part of the common Scandinavian culture. Instead a local,endemic cultural expression had developed; a seclusion which lasted forcenturies despite the islands central position in the Baltic Sea. In thepast, key elements for the understanding of local settlement- and burialpractices as well as the local material culture were mainly recovered andreported by local farmers. A specific category of such finds – so-called‘bronze slag’ is discussed and partly reinterpreted in the first study ofthis thesis. Two further studies treat different aspects of metalworkingand metalworkers – one discusses common archaeological notions ofScandinavian workshops, production sites and metalworkers from a criticalperspective while the other mainly focuses on the Gotlandic finds frommetal-detector surveys carried out over the last 35 years. Based on whereand to which extent, both from a quantitative and a qualitative point ofview, these finds occur a hierarchical classification into four sub groupsis presented – ordinary farm sites with traces of non-ferrous metalworking,workshop sites, potential workshop sites and last, extrovert harboursettlements. A fourth study presents an attempt to evaluate the usefulnessof magnetometry in delimiting extant traces of high-temperature crafts,such as metalworking. The last study of the thesis presents an attempt touse trace elements analysis of skeletal lead in human bone to identifypotential non-ferrous metalworkers. As the wearing of endemic Gotlandic jewellery appears to have been centralin the manifestation of the local identity it is argued that themetalworking artisans played a crucial role in defining how this identitywas signalled and displayed via the jewellery and dress-related metalobjects. It is further suggested that these artisans might have played animportant role in upholding the local economy before the advent of localminting. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 5: Manuscript.</p>

Suite aux fouilles du second atelier monétaire royal de La Rochelle (17), une grande quantité de matériel a pu être mis au jour. Cette découverte est exceptionnelle par deux aspects puisqu’il s’agit à ce jour de l’unique atelier officiel fouillé en France et que les structures et objets découverts permettent en une première lecture, d’ébaucher une chaîne de production de la monnaie. Ce matériel précurseur complété de céramiques provenant de l’atelier médiéval de Montreuil-Bonnin (86) constitue la base de cette étude archéométrique inédite des techniques monétaires officielles. Cette recherche, par définition multidisciplinaire, s’appuie sur la caractérisation physico-chimique de corpus archéologiques mais également sur une étude des sources historiques : traités monétaires, procès-verbaux, comptes d’atelier... Enfin, les reconstitutions paléométallurgiques participent pour une part importante aux discussions engagées. Elles renseignent sur la complexité des opérations tout en produisant des analogues librement étudiables, comparés aux échantillons anciens. La compilation de toutes les données collectées permet non seulement de proposer une description des techniques du monnayage au marteau telles qu’elles étaient mises en oeuvre dans les fabriques monétaires jusqu’au milieu du XVIIe siècle et de révéler les matières premières utilisées mais également de comprendre le fondement des opérations pratiquées. En tant que fabrication monétaire particulière, les techniques propres au faux-monnayage ont parallèlement été considérées par le biais de l’étude de deux exemples localisés au début de la Période Moderne dans le département de l’Aude (11). En suivant la même démarche expérimentale, il a été possible de mettre en évidence les particularismes de ces activités et de révéler plusieurs analogies avec les techniques officielles. / In the Nineties excavations made in La Rochelle (France) have produced objects of archaeometallurgical evidence with regards to the second royal mint. For the time being, this workshop is still the only one that has been discovered in France. Moreover, the observations of the artefacts seem to allow the reading of the whole money making process. These archaeological samples, complemented with ceramics from the medieval mint of Montreuil-Bonnin (France), have been studied by an archaeometric approach to propose an original research on the official French hammer striking process. This multidisciplinary study is based on the analysis of historical samples but also on a bibliographic compilation: monetary treaties, official reports, mint accounts… The experimental work takes an important part in the study too. Providing more than experimental samples easily studied and compared with the archaeological ones, this pragmatic method allows to point out the complexity of a technique. Finally, the gathering of all data defines the raw materials and the processes used in the French hammer coining until the mid XVIIth century, but also their respective purposes. As a particular coinage, counterfeiting has also been studied through two post-medieval examples that took place in Southern France caves. The experimental study reveals the originalities of these illegal activities besides some links with the official processes.

Prospektionen der Universität Leipzig im Umkreis des römischen vicus Belginum ergaben bei Wederath, Flur Hinterm Klop (Gde. Morbach, Kr. Bernkastel-Wittlich, Rheinland Pfalz) eine mutmaßliche villa rustica. Unterschiedlich große Steinkonzentrationen weisen auf ein Haupt- und mehrere Nebengebäude. Das Fundmaterial besteht vorwiegend aus Ziegeln (Dach-, Fußboden- und Hypokaustenziegeln) und relativ wenig Keramik. Die bestimmbare Keramik datiert in das 2./3. Jh. n. Chr. / Archaeological prospections by the University of Leipzig in the surroundings of the Roman vicus Belginum revealed near Wederath (Rhenania-Palatinate, Germany) a villa rustica. Stone concentrations of different dimensions are indicating the main and several minor buildings. The finds are consisting mainly of bricks and relatively few ceramic sherds. The ceramics are dating into the 2nd/3rd cent. AD.
