I began taking a part in fieldwork in the Albegna Valley in 1982 and from that a PhD thesis at the University of London eventually emerged and was completed in 1995. I have accumulated debts of gratitude to many people during this time. All of the people who have walked fields in the Albegna valley and Ager Cosanus have contributed to this study. Particular thanks are due to Sally, Louisa, Clio and Eleanor and also to Lisa and James Fentress who have helped in very many ways. Thanks are also due to Andrea Carandini whose support has made this research possible, and to Lucy Walker for her patient work at Doganella, to Ida Attolini for her social skills at Tartuchino and to Derek Kennet for his help in surviving on 10 lire a day while studying the finds from Doganella. Work in Siena was only possible through the hospitality of Michelle Hobart, Professor Pino Pucci and Battista Sanguineto. Many of the people who live in and farm the Albegna Valley and Ager Cosanus have provided generous hospitality and plenty of advice.
Many institutions and individuals have helped to promote the field survey project in the Albegna Valley and the Ager Cosanus. The field survey itself was initiated by Professor Andrea Carandini, now of the University of Rome, and co-ordinated by Dott.ssa Maria Grazia Celuzza of the Museo Archeologico della Maremma in Grosseto and Professor Elizabeth Fentress now of the American Academy in Rome. The research has been generously supported in Italy by the Universities of Pisa and Siena, the Commitato Nazionale di Ricerca Scientifica, the Regione di Toscana, the Provincia di Grosseto, the Comunita Montana di Monte Amiata, the communes of Orbetello, Magliano in Toscana, Manciano and Semproniano. Many British institutions have also supported the project. These are the Sette Finestre Committee, the British Academy, the Society of Antiquaries of London, the British School at Rome (Faculty of Archaeology, History and Letters), the Gordon Childe Bequest (Institute of Archaeology, University College London), the Craven Committee of the University of Oxford, the University of Cambridge (Faculty of Classics) and the University of Durham Excavation Committee. Publication of the excavation of the farm at Podere Tartuchino was made possible by the award of the Ellaina Macnamara Memorial Scholarship. The project would not have been possible without the support and encouragement of the Soprintendenza Archeologica per la Toscana, particularly the Superintendent Prof. F. Nicosa and Dott. G. Ciampoltrini.
Grateful thanks are due to Professor John Wilkes of the Institute of Archaeology, University College London, for his supervision of the thesis from which this study derives. Both the University of Glasgow and Birkbeck College, University of London, have contributed to this study by being generous with their institutional time. Thanks are also due to the invaluable support provided over the years by the librarians and staff of the Library of the British School at Rome. The text of the thesis and the database have been revised and converted into HTML during a period of study leave from the Open University.
