The Zoroastrian Faith is organized around five themes: an account of Zoroaster's life and work; discussion of the development and spread of Zoroastrianism from its beginnings to the present; description of the sacred writings and religious documents of the faith; an analysis of the basic Zoroastrian beliefs and their influence on Judaism, Christianity, and Islam; and a description of the prescribed observances. In this historical and analytical study, S.A. Nigosian cuts through these problems to present a concise, systematic survey of Zoroastrianism. This book will intrigue scholars and general readers alike. A glossary and bibliography are provided as aids for further study
