This book is the first in the multi-author series Maritime Encounters, outputs of the major six-year (2022?2028) international research initiative, funded by Sweden's central bank. Our programme is based on a maritime perspective, a counterpoint to prevailing land-based vantages on Europe's prehistory. In the Maritime Encounters project a highly international cross-disciplinary team has embarked on a diverse range of research goals to provide a more detailed and nuanced story of how prehistoric societies realised major and minor sea crossings, organised long-distance exchange, and adapted to ways of life by the sea in prehistory. Recent advances with ancient DNA have brought migration back into archaeological explanation, but little attention has been paid to maritime aspects of these movements or the maritime legacies inherited from indigenous cultures. The formation of the populations, cultures and languages of Europe are now seen largely as consequences of three great prehistoric migrations: hunter-gatherers repopulating the post-glacial landscape, followed by farmers spreading from Anatolia, and then Indo-European-speaking pastoralists from the steppe. There is a significant gap in this current model that we sense most acutely in Scandinavia and the British Isles. Unanswered questions include: How these groups reached the islands and peninsulas of Atlantic Europe? What types of boats were used? How many people and animals could they carry? To what extent did indigenous coastal peoples contribute traditions and knowledge of boats, boat building, seaways, navigation, and subsistence in coastal environments. How was the long-distance trade in metals organised during the European Bronze Age? And what was the impact of this sea-crossing network on the cultures, languages, and populations of the producers and consumers of bronze? AUTHORS: John T. Koch is Research Professor at the University of Wales Centre for Advanced Welsh and Celtic Studies in Aberystwyth. A historical linguist specialising in early Celtic languages with a unique multidisciplinary profile, Koch's research includes Indo-European origins of Celtic names, words, and grammar. Mikael Fauvelle is a researcher in the department of archaeology and ancient history at Lund University. He is an anthropological archaeologist specialising in early complex economic systems and the emergence of maritime trade networks. His research has focused on topics including the origins of money, the innovation of ancient watercraft, and the formation of early chiefdoms. He has directed archaeological field projects in North America, Central America, and Scandinavia. Sir Barry Cunliffe is Professor Emeritus of European Prehistory in the University of Oxford. A phenomenally prolific author and excavator, his publications include highly readable synthetic overviews that encompass long chronological sweeps of the archaeology of Britain, Eurasia, the Celtic world, and the Atlantic facade. Johan Ling is Professor of Archaeology at the Department of Historical Studies, Gothenburg University and is Director of the Rock Art research Archives (SHFA). He is a specialist in Bronze Age archaeology with a focus on Scandinavian rock art and maritime trade. 120 colour and b/w illustrations
