The following paper aims to unveil connections between pre-Qin Chinese Mythology and two ancient mantic texts, the well-known Zhouyi 周易 on the one hand and the lesser-known Guicangyi 歸藏易 on the other. The bronze age text of the Zhouyi 周易, being the core text of the Yijing 易經, is conspicuously lacking in mythic elements. In fact, this seems counterintuitive, given the text’s mantic and shamanic background and the epoch of composition. This lack of mythic character is somewhat lenified by both the extant and recently unearthed fragments of the alternative Guicang text, a text that shares the hexagram structure of the Zhouyi but presents a text strikingly different and significantly mythic. Several narrative strands in the Zhouyi were reconstructed by Wang Guowei 王國維, Gu Jiegang 顧頡剛, Gao Heng 高亨, and others in the first half of the twentieth century. Some of these have unmistakable links with China’s richest repositories of myth, such as the Shanhaijing 山海經 and Chuci Tianwen 楚辭天問 while most of them are grounded in attestable history. The Guicangyi’s textual transmission and history is a rather complicated affair, but for our present purposes, we can refer to two main sources. The first of those is a compendious collection of various fragments of lost books, one of the earliest chapters of which collects the most extant references to the disputed Guicangyi. At the time, the text’s authenticity was highly disputed. The second source served to settle this century-old dispute in the wake of an archeological discovery in 1983 that included almost 400 slips of bamboo with writing, demonstrated to be remnants of the same text. Among the mythological and historical elements investigated here are: Chinese dragons, the semi-historical or legendary King Hai 王亥 of pre-dynastic Shang 商, Gaozong 高宗 (i.e., Wuding 武丁), Diyi 帝乙, Jizi 箕子, Kang Hou 康侯 (i.e., Ji Feng 姬封), Gun 鯀, Yu 禹, the maiden of Tushan 塗山女and Qi lord of Xia 夏后啓.
