“Elsewhere Lankford reiterates that this belief system was by no means confined to the Plains, the Eastern Woodlands, and the Mississippi Valley. It is better understood, he argues, as part of 'a widespread religious pattern' found right across North America and 'more powerful than the tendency towards cultural diversity.' Indeed, what the evidence suggests is the former existence of 'an ancient North American international religion ... a common ethnoastronomy ... and a common mythology. Such a multicultural reality hints provocatively at more common knowledge which lay behind the façade of cultural diversity united by international trade networks. One likely possibility of a conceptual realm in which that common knowledge became focused is mortuary belief [and] ... the symbolism surrounding death.” MythologyLegacySymbolismOriginBelief SystemPatternEthnoastronomy Book:America Before: The Key to Earth's Lost Civilization Source: America Before: The Key to Earth's Lost Civilization
