The Mawangdui Silk Texts (traditional Chinese: 馬王堆帛書; simplified Chinese: 马王堆帛书; pinyin: Mǎwángduī Bóshū) are Chinese philosophical and medical works written on silk which were discovered at the Mawangdui site in Changsha, Hunan, in 1973. They include some of the earliest attested manuscripts of existing texts (such as the I Ching), two copies of the Tao Te Ching, a copy of Zhan Guo Ce, works by Gan De and Shi Shen, and previously unknown medical texts such as Wushi'er Bingfang (Prescriptions for Fifty-Two Ailments).[1] Scholars arranged them into 28 types of silk books. Their approximately 120,000 words cover military strategy, mathematics, cartography, and the six classical arts: ritual, music, archery, horsemanship, writing, and arithmetic.[2]
