Abstract: This article investigates the original Chinese sources for two circular trigram arrangements that have played a crucial role in numerology associated with the Book of Changes (the Yijing 《易 經》) since the Song dynasty (960–1279). While attempting to clarify the nature and the origins of these and related diagrams, recent secondary literature on topic is reviewed, especially the influential articles by Schuyler Cammann.
