Thirty-eight essays are brought together in this volume to honor Hermann Landolt of the Institute of Islamic Studies at McGill University, Canada. A broad range of participants, including former students and colleagues both close and distant, have contributed essays, most of which deal with aspects of Ismaili, Ithna-ashari, or Sufi thought. Almost all of the essays are in English; four are in French, however. The range of topics is catholic, to say the least, and the rough chronological ordering of the essays can hardly contain them.
