Translations of the Yi jinginto western languages have been biased towards the yili('meaning and pattern') tradition, whereas studies of the xiangshu('image and number') tradition - which takes as its point of departure the imagery and numerology associated with divination and its hexagrams, trigrams, lines, and related charts and diagrams - has remained relatively unexplored. This major new reference work is organised as a Chinese-English encyclopedia, arranged alphabetically according to the pinyinromanisation, with Chinese characters appended. A character index as well as an English index is included. The entries are of two kinds: technical terms and various other concepts related to the 'image and number' tradition, and bio-bibliographical information on Chinese Yi jingscholars. Each entry in the former category has a brief explanation that includes references to the origins of the term, cross-references, and a reference to an entry giving a more comprehensive treatment of the subject.List of plates Common Abbreviations Conventions Introduction A Companion to Yi Jing Numerology and Cosmology Plates (between pages 348 and 349) Selected Bibliography Index of Common English Translations of the Hexagram names Index of Chinese Works'A great deal of conscientous work has gone into the creation of the volume.'- Bulletin of the SOAS
