Rudolf Ritsema(1918-2006) was a renowned I Ching scholar and director of the international Eranos Centre for East West Studies, founded in the 1930s by C G Jung and Olga Froebe-Kapteyn. Ritsema refined and tested the initial translation of the text through the Eranos Round Table Sessions. Shantena Augusto Sabbadini,a former theoretical physicist, joined Rudolf Ritsema to help run the Round Table Sessions and together they produced this translation of the I Ching, a distillation of the Eranos Round Table Sessions experience and of the authors' I Ching studies.
