The two volumes of this investigation into how we perceive sacred architecture propose an original intepretation of built environments as ritual-architectural events. Exploring the world's cultures and religious traditions, Volume 1 maps out patterned responses to sacred architecture according to the human experience, mechanism, interpretation and comparison of architecture. Volume 2, an exercise in comparative morphology, offers a comprehensive framework of ritual-architectural priorities by looking at architecture as orientation, as commemoration and as ritual context.
