The Podcast explores the history and authorship of the Yi Jing, or Book of Changes, a foundational text in Chinese culture. Multiple figures are credited with its development, including the mythical Fu Xi, who is said to have created the earliest trigrams, and King Wen of Zhou, who is attributed with expanding them into 64 hexagrams. The Duke of Zhou further contributed by adding interpretations to the hexagrams, while Confucius's commentaries significantly shaped the text's philosophical understanding. The sources detail each individual's contributions, acknowledging the complex and layered history of the Yi Jing's creation and evolution over millennia.
