A series of 2,200-year-old Chinese texts, written on silk and found buried in ancient tombs, contain the oldest surviving anatomical atlas, scientists say. 

The texts were discovered in the 1970s within tombs at the site of Mawangdui in south-central China. The tombs belonged to Marquis Dai, his wife Lady Dai and their son. The texts are challenging to understand, and they use the term "meridian" to refer to parts of the human body. In a paper recently published Sept. 1 in the journal The Anatomical Record, a research team led by Vivien Shaw, an anatomy lecturer at Bangor University in Wales in the United Kingdom, argues that these texts "are the oldest surviving anatomical atlas in the world."
