Between 1999 and 2009, the chair for History of Hermetic Philosophy and Related Currents at the University of Amsterdam succeeded in establishing itself as the most important centre for study and teaching in this domain, and strongly contributed to the establishment of Western esotericism as a recognised academic field of research. This volume was published at the occasion of the 10th anniversary. It contains a history of the creation and development of the chair, followed by articles on aspects of Western esotericism by the previous and current staff members, contributions by students and Ph.D. students about the study program, and reflections by international top specialists about the field of research and its academic development.
