It would not have been possible to write this novel without the collaboration, conscious or unconscious, of many people who helped me on my journeys through the Congo and Amazonia and in Ireland, the United States, Belgium, Peru, Germany, and Spain, sent me books and articles, facilitated my access to archives and libraries, gave me testimonies, advice, and above all, their encouragement and friendship when I felt myself weakening in the face of the difficulties of the project I had in hand. Among them, I want in particular to thank Verónica Ramírez Muro for her invaluable help during my visit to Ireland and in the preparation of the manuscript. I alone am responsible for the deficiencies of this book, but without these people, its eventual successes would have been impossible. Many thanks to:
