Guodian Daodejing Manuscripts (c. 300 BCE or earlier)
The oldest surviving Daodejing fragments, excavated in 1993 from a Chu tomb at Guodian sealed around 300 BCE — the earliest material witness to the text.
Event: In 1993, archaeologists excavated a Chu-state tomb at Guodian (Jingmen, Hubei) containing bamboo slips with the earliest known Daodejing fragments, sealed no later than ~300 BCE — possibly earlier. The slips preserve passages of the text in an order and wording that differ from the received version, proving the text was still forming at that date.
Evidence class: archaeological (primary); the seal-date is an inference from tomb typology (scholarly).
Why it matters here: the Guodian slips ground the Daodejing’s antiquity in material evidence independent of the Laozi legend, and complicate the tradition’s single-author account. See the Daodejing page.
