Zohar-"the book of Splendor, Radiance, Enlightenment"--has fascinated readers from its first appearance in thirteenth-century Spain until today. It is the major text of Kabbalah, the Jewish mystical tradition. To assure the acceptance of his work within the Jewish community, a Spanish scholar named Moses de Leon claimed that Zohar was an ancient work of the school of the famous Rabbi Shim'on son of Yohai. It was not until our own century that critical scholarship demonstrated that the book's author was Moses de Leon himself. His mosaic of Scripture, Midrash, medieval homily, fiction, and fantasy presents what Professor Daniel Matt describes as "a challenge to the normal workings of consciousness [that] dares one to examine one's assumptions about tradition, God, and self."D.
