Folklore says that a river was diverted over his grave to make it impossible to find (echoing the manner of burial of the Sumerian King Gilgamesh of Uruk or of the Visigoth leader Alaric).[1] Other tales state that his grave was stampeded over by many horses, that trees were then planted over the site, and that the permafrost also played its part in the hiding of the burial site.[3] The Erdeni Tobchi (1662) claims that Genghis Khan's coffin may have been empty when it arrived in Mongolia. Similarly, the Altan Tobchi (1604) maintains that only his shirt, tent and boots were buried in the Ordos (Ratchnevsky, p. 143f.). Turnbull (2003, p. 24) tells another legend in which the grave was re-discovered 30 years after Genghis Khan's death.
