THE ARCHAEOLOGY OF ROMAN SURVEILLANCE IN THE CENTRAL ALENTEJO, PORTUGAL CALIFORNIA CLASSICAL STUDIES NUMBER 5 Editorial Board Chair: Donald Mastronarde Editorial Board: Alessandro Barchiesi, Todd Hickey, Emily Mackil, Richard Martin, Robert Morstein-Marx, J. Theodore Peña, Kim Shelton California Classical Studies publishes peer-reviewed long-form scholarship with online open access and print-on-demand availability. The primary aim of the series is to disseminate basic research (editing and analysis of primary materials both textual and physical), data-heavy re- search, and highly specialized research of the kind that is either hard to place with the leading publishers in Classics or extremely expensive for libraries and individuals when produced by a leading academic publisher. In addition to promoting archaeological publications, papyrolog- ical and epigraphic studies, technical textual studies, and the like, the series will also produce selected titles of a more general profile. The startup phase of this project (2013–2017) is supported by a grant from the Andrew W. Mellon Foundation. Also in the series: Number 1: Leslie Kurke, The Traffic in Praise: Pindar and the Poetics of Social Economy, 2013 Number 2: Edward Courtney, A Commentary on the Satires of Juvenal, 2013 Number 3: Mark Griffith, Greek Satyr Play: Five Studies, 2015 Number 4: Mirjam Kotwick, Alexander of Aphrodisias and the Text of Aristotle’s Meta- physics, 2016 THE ARCHAEOLOGY OF ROMAN SURVEILLANCE IN THE CENTRAL ALENTEJO, PORTUGAL Joey Williams CALIFORNIA CLASSICAL STUDIES Berkeley, California © 2017 by Joey Williams.

First and fore- most, I must thank the faculty at the University at Buffalo, especially my advisor Prof. Bradley Ault, for shepherding this project from inception to dissertation. Much of my perspective on archaeological materials was shaped by Prof. J. The- odore Peña and Prof. Archer Martin. They have both offered abundant encour- agement and guidance, and they are greatly appreciated. The PortAnta Archae- ological Cooperative and the National Museum of Archaeology in Lisbon have supported my work since I first visited Portugal as a field school student. Without their generosity this project would never have been conceived. The support of the municipality of Redondo continues to be essential to the excavation at Caladinho and other archaeological projects in Alentejo. I must of- fer profound thanks especially to Rui Mataloto. Our work together provided the stimulus for this project, and I am forever grateful that he agreed to excavate a little hilltop called Caladinho with me. Caladinho has grown significantly since those first days, and I have many people to thank for bringing that fieldwork to fruition. The staff, volunteers, and friends of the Caladinho Archaeological Proj- ect—Catarina Alves, Brandi Bethke, Rui “Josué” Clemente, Inês Conde, Andrew Donnelly, José Inverno, Michael Kat, Emma Ljung, Mark Nakahara, Mark Paw- lowski, Karilyn Sheldon, and Rhodora Vennarucci—were instrumental in com- pleting the four seasons of excavation that anchor this book. I must also thank our field school students, too numerous to mention individually, whose hard work in difficult conditions made all this possible. I am also grateful to my excavation colleagues for allowing me to publish here their photos and drawings related to Caladinho and other sites in Portugal. Specif- ic credits are included in the captions. Please note that only a few select Figures are printed in this book, while the entire set is freely available online at eScholarship. org, the website that provides open-access viewing of this work. The anonymous referees and the editorial board of California Classical Stud- ies were indispensable in reshaping this project from dissertation to publication ix x acknowledgments Donald Mastronarde read and commented on multiple drafts of this book, and it has improved a great deal thanks to his guidance. I am also thankful for the editorial assistance provided by Elizabeth Ditmars in the final stages of the manu- script’s preparation. Any remaining errors in the text are mine alone. This book was made possible by several institutions. The Department of Classics at the University at Buffalo supported my work in its doctoral program through fellowships, summer research funds, and teaching assistantships. The University at Buffalo also provided the software necessary for the chapter on visibility anal- ysis. Financial support for some of the fieldwork was also provided by the Mark Diamond Research Fund of the University at Buffalo’s Graduate Student Associ- ation. Over many summers, Rui Boaventura and Maia Langley of the PortAnta Research Cooperative provided me with food, shelter, and good company (the three primary needs of any archaeological research). I must thank them both for introducing me to the archaeology of Portugal. The completion of this research was made possible by a doctoral exchange fellowship offered by the Faculté des Lettres at the University of Lausanne, Switzerland. My deepest gratitude goes to Brandi Bethke. She has enthusiastically supported and patiently endured the writing of my dissertation and the writing of this book. There are no words sufficient to express the depth of my affection. Thank you. Finally, this book is dedicated to my grandmother, Ava Crossno, who was an excellent storyteller.
