More than 3,000 years ago, a Shang king sought to know whether the next 10 days would bring misfortune. An ox's shoulder blade preserves the questions, the predictions and accounts of what happened afterwards. 

The bone, now displayed at the National Museum of China in Beijing, is about 32 centimeters long. The carved characters still bear traces of red pigment. Its inscriptions record royal rituals, hunting and happenings in the sky. It is a remarkable survivor from a world in which rulers sought guidance from ancestors and spirits before making decisions.

It came from Anyang, in central China's Henan Province, roughly 500 kilometers south of Beijing. Here lie the remains of Yinxu, a royal capital during the final centuries of the Shang Dynasty, which ended around 1046 BCE. Excavations have uncovered palaces, royal tombs and finely worked bronzes. The inscribed bones offer something more intimate: records of what people asked, feared and expected.

The practice behind them explains their name. Diviners applied heat to prepared cattle bones or turtle shells, then interpreted the resulting cracks as answers to questions. The inscriptions could preserve the prediction and, occasionally, what actually happened afterwards. Matters of state appeared alongside concerns about harvests, illness and the influence of ancestors.

The red-pigmented bone is unusually complete. Despite some damage, it preserves all four elements scholars look for in a full divination record: the circumstances, the question, the prediction and the outcome. Together, these allow us to follow a sequence of thought across an extraordinary distance in time.

Such records have transformed the study of early China. They provide contemporary evidence of people and events that would otherwise be known largely through much later accounts. Their perspective is selective, centered on the royal court, but that makes the voices they preserve no less revealing.

The inscriptions began attracting scholarly attention in 1899. More than a century later, much remains unread. Researchers have identified more than 4,500 distinct characters, of which roughly a third have been deciphered. The bones preserve China's earliest known mature writing system, yet recovering everything they say remains painstaking work.

Their visual appeal is easier to grasp. Even without reading the words, a viewer can appreciate the red-pigmented bone's large, balanced characters, forceful lines and carefully arranged inscriptions. The surviving color adds another dimension to an object that once held ritual significance. These are qualities that connect the study of ancient writing with the appreciation of calligraphy.

Writing in the Shang world also appeared on bronze ceremonial vessels. Some early signs retained recognizable human or animal shapes; others became increasingly economical arrangements of lines. Materials mattered: carving into bone imposed different demands from casting an inscription in bronze. Across these surfaces, the visual possibilities of Chinese writing were taking shape.

Over the following centuries, new scripts and styles developed. The Qin Dynasty promoted a standardized form of writing, while clerical script matured under the Han. Later calligraphers explored regular, running and cursive forms, finding different balances between clarity, discipline and movement. Older styles continued to be studied and practised alongside newer ones.

That history is one of continuity through change. Chinese characters have altered greatly in appearance, and knowing modern Chinese does not make an oracle-bone inscription easy to read. Yet the connection survives, linking the royal records of the Bronze Age to a writing tradition still used and reinvented today.

The king's question concerned the next 20 days. Its words have outlasted his dynasty by more than three millennia.
