The Zhou Changes, better known in the West as I Ching, is one of the masterpieces of world literature. This book, the climax of more than forty years of research in Chinese archaeology, explores the text's origins in the oracle-bone and milfoil divinations of Bronze Age China and how it transformed over the course of the Zhou dynasty into the first of the Chinese classics. The book provides an in-depth survey of the theory and practice of divination to demonstrate how the hexagram and line statements of the text were produced and how they were understood at the time.

A great number of historical examples show how desperate people sought to obtain a glimpse of the future or explain certain incidents retrospectively through signs that had occurred in advance. In that sense, signs are always considered a portent of future events. In different societies, and at different times, the written or unwritten rules regarding their interpretation varied, although there was perhaps a common understanding of these processes. This present volume collates essays from specialists in the field of prognostication in the European Middle Ages. Contributors are Klaus Herbers, Wolfram Brandes, Zhao Lu, Rolf Scheuermann, Thomas Krumpel, Bernardo Bertholin Kerr, Gaelle Bosseman, Julia Eva Wannenmacher (), Matthias Kaup, Vincent Gossaert, Jurgen Gebhardt, Matthias Gebauer, Richard Landes.
