Book excerpt: Back in print after ten years, this searching work uses the imagery of icons as the basis for an exploration of the true mystical source of the Christian faith. Richard Temple points out that icons themselves are essentially mystical at heart, for they are the key to an underground stream of knowledge aimed at the civilization of the whole person -- body, soul, and spirit -- that developed from Platonic thought, the school of Alexandria, and the Orphic mysteries. As the author discusses the meaning of the icons depicted in this volume, the richness and profundity of a lost tradition is gradually and hauntingly revealed.
