We would like to thank the various people consulted in the writing of this book, especially Dr. Simon Wilson for his expert analysis of Der Jüngere Titurel and the Church of Ettal; to David Elkington for his careful reading of various drafts of the manuscript and his comments thereon, and for first pointing us to the East; to Janet Piedelato for venturing into the depths of the New York Public Library to examine and comment on the papers of Arthur Upham Pope and Phyllis Ackerman. A very big thank you to Melanie Kinghan for her translation of the essay by Sulpiz Boisserée, carried out with exemplary care in the midst of a busy life. Special thanks, as always, to Caitlín Matthews for all her support, for taking time out of her busy schedule to point out avenues of research we might otherwise have missed, and for translating passages from Latin and French.
Needless to say, we are solely responsible for any errors of fact that escaped our notice. Despite working with the first scholarly edition of Sone de Nansay by Goldschmidt, we could not have ventured far down the path without access to the edition prepared by Dr. Claude Lachet, whose commentary and modern French translation were also immensely useful.
Thanks also to our editor at Llewellyn, Bill Krause, and the rest of the production team for making the process flow smoothly. Grateful thanks to Wil Kinghan for drawing the diagrams included in this book.
