Jiahu symbols

China, and excavated in 1989. The Jiahu symbols are dated to around 6000 BC.^[1] Although at first a total of 16 signs were identified, intensive scrutiny has found there to be only 11 definitely incised signs, of which 9 were incised on tortoise shells and an additional 2 on bone.^[2] The archaeologists who made the original finds believed the markings to be similar in form to some characters used in the much later oracle bone script (e.g. similar markings of 目 "eye", 日 "sun; day"), but most doubt that the markings represent systematic writing.^[3] A 2003 report in Antiquity interpreted them "not as writing itself, but as features of a lengthy period of sign-use which led eventually to a fully-fledged system of writing".^[2] The earliest known body of writing in the oracle bone script dates much later to the reign of the late Shang dynasty king Wu Ding, which started in about c. 1250 BC^[4] or 1200 BC.^[5]
