Twelfth century BC

The Twelfth century BC marks the period in which the main text of the I Ching took shape in the historical reconstruction presented here. Its beginnings are associated with King Wen’s imprisonment at Youli amid the crisis of the Shang realm; a larger portion is attributed to his son, the Duke of Zhou, and the text is said to have been complete before the Duke’s death in 1105 BC. The account thus distinguishes this early textual formation from the later appendixes, commentaries, and editorial arrangements through which the classic was transmitted.

A text formed amid dynastic crisis

The work’s historical setting is a kingdom described as disorganized and demoralized under the Yin, or Shang, rulers. A brother of the reigning monarch lamented that drink had undone the founder’s virtue, that robbery and treachery spread among the people, that nobles and officers violated the laws, and that criminals could not reliably be brought to justice. The country’s condition was likened to crossing a great stream without finding either ford or bank. The account attributes much of this disorder to the monarch’s character and tyranny.

In the western principality of Zhou, by contrast, its chief, King Wen, had gained distinction for ability, virtue, and self-restraint. He had succeeded his father in 1185 BC and become a kind of viceroy over a large part of the kingdom. Although other princes and people might have welcomed an attack on the tyrant, King Wen avoided exposing himself to the charge of disloyalty. The ruler’s suspicion eventually turned against him: in 1143 BC he was imprisoned at Youli, where the order for his death might arrive at any moment.

Youli and the formation of the text

The account places King Wen’s work with the lineal figures in the perilous interval of his confinement. Divination by trigrams was already an established practice, and the stalks used for divining are also mentioned in early writings. The author suggests that King Wen may have been familiar with divination as a national institution, and speculates that studying the figures could have appeared harmless to his suspicious captors. The possibility is offered as conjecture, not as a securely established motive.

The narrative imagines the imprisoned ruler with the sixty-four figures arranged before him. He gave each figure a name expressing an idea he associated with it, drawing meanings from nature, human society, and the condition or prospects of the kingdom. He then attached counsel or warning to those meanings. In this reconstruction, the work did not simply reproduce divinatory practice: it sought to confine its uncertainties within a framework of rational and moral reflection. The portion attributed to King Wen is dated to 1143 or 1142 BC, perhaps begun in the former year and completed in the latter.

The Duke of Zhou and the early classic

King Wen is credited with only a small part of the work as it survives. A greater share is attributed to his son Tan, known as the Duke of Zhou. These passages refer to King Wu, who succeeded King Wen and became the first sovereign of the Zhou dynasty, as well as to events in the early years of the following reign. Since the Duke of Zhou died in 1105 BC, the account concludes that the I Ching in its received form was complete a few years before that date, in the last decade of the twelfth century BC.

This layered authorship matters to the book’s chronology. The main text is associated with King Wen and the Duke of Zhou, whereas the appendixes conventionally linked with Confucius are placed centuries later. Even if Confucius composed some of them, he could not have begun them before 483 BC—roughly six centuries after the portion attributed to King Wen and nearly 630 years after the Duke of Zhou’s contribution. The account therefore rejects treating the text and appendixes as a single work composed at one time, and warns that printing later material alongside the older text can blur their different historical settings and ideas.

Divination, transmission, and later interpretation

The early setting also clarifies what divination meant in the account. It was not presented as a means to know future events absolutely, but as a way to judge whether plans and contemplated circumstances were likely to turn out well or badly. In the procedure described in a later appendix, forty-nine stalks were manipulated three times for each line, making eighteen manipulations to form a hexagram. Odd numbers produced strong, undivided lines and even numbers weak, divided ones; the resulting figures were interpreted through King Wen’s judgments and the Duke of Zhou’s line statements. The numbers served to construct the figure, not as independent principles governing the material world.

The book’s subsequent history is sharply separated from this early period. The I Ching survived Qin Shi Huang’s book burning in 213 BC because it was classed as a work of divination, a category exempted from the proposed destruction. By the beginning of the Common Era, a library catalogue listed works on the classic and its appendixes from thirteen authors or schools, in 294 portions. The imperial edition published in 1715 quoted 218 scholars, whose commentaries spanned from the second century BC to the seventeenth century. These layers of preservation and interpretation attest to the classic’s long reception, but they do not erase the chronological distinction between the twelfth-century-BC text and its later appendixes.
