The editors are extremely grateful to the British Archaeological Association, which first sponsored this project, and to the Courtauld Institute of Art which generously collaborated in holding and organising the colloquium from which this book derives. Stephen Whiteman, Grace Williams, and our copyeditor, Robyn Roslak, have been both flexible and efficient in producing this book, and we are grateful to them as well as to Lucy Bradnock and Tom Nickson, who initially helped with moving the book forward. We are indebted to the two anonymous reviewers for their careful and insightful reports, which contributed greatly to the outcome. We would also like to thank the British Archaeological Association for assistance with the illustrations, Andrew Winslow, who expertly took many of the recent photographs of the Cross that appear here, and Julia Perratore, for arranging this.
