The Silk Library of Tomb Three

Chinese archaeologists opened the third of the three Mawangdui tombs in 1973 and found, alongside medical treatises, star charts and a map, a folded and torn cache of silk sheets that had been sealed inside since 168 BC. Once conserved, the sheets proved to hold two complete copies of the Tao Te Ching, older than any manuscript previously known by roughly four centuries, along with a version of the Yijing whose sixty-four hexagrams follow an entirely different sequence from the received Zhouyi and whose commentary layers differ from the transmitted text at many points.

A third major work, since named the Huangdi Sijing or Four Classics of the Yellow Emperor, survived nowhere else at all and reshaped scholarly arguments about the early history of Huang-Lao thought, the fusion of Yellow Emperor lore with Laozi's teaching that flourished at the early Han court. The silk had been folded rather than rolled for storage, which tore many sheets along the fold lines, and conservators spent years reassembling legible columns from fragments before translation could properly begin. Because the manuscripts were sealed in a datable tomb rather than copied and recopied across centuries, they let scholars watch textual variants accumulate over time in a way no transmitted classic allows, most famously in the Tao Te Ching's best known line, which the Mawangdui version renders as acting without contrivance rather than the softer acting through non-action familiar from later editions.
