 Textual theory was further complicated when archeologists unearthed new copies of the Daode Jing. The traditionally dominant text was named after one of the earliest commentators—the Wang Bi version. Most translations deviated only slightly from that traditional version prior to the first archeological discovery in 1973. In that year, two versions of the Daode Jing were unearthed in a Mawang Dui tomb site. The discovery energized textual theorists who reasoned that as the earliest physically extant text, the Mawang Dui must be closer to the original should be treated as authoritative. The discovery was quickly followed by a rash of new translations of the Dedao Jing (the two parts of the text were reversed in the newly discovered manuscripts).
