This book is written by scholars immersed in the cultures of antiquity and the medieval epoch. The disciplines represented include comparative literature, comparative religion, classics, Jewish studies, anthropology, Native American studies, folklore, and mythology. The book is addressed primarily to scholars in these fields. It is not an easy read. This is not said to alarm you but to alert you to the fact that the level and at times abstract quality of the discourse requires some getting used to by the nonspecialist. The contributors, understandably working with primary sources, have found it necessary to resort to the original language where any translation would fail to convey the precise meaning. This is well and good, and for the most part the translation and the context suffice. In a few instances, however, the original Greek, Latin, Arabic, Hebrew, German, and French stand alone and the context is not quite sufficient. This is a minor irritant in a text that succeeds memorably in depicting the interpenetrability of dreams and culture.
