Osage Hopewell Star Chart. The Key to the Hopewell Earthworks in the Ohio Valley.
None of the younger Osage men knew about these matters and the author was urged not to speak to them on this subject. He observed that several of the elder men, members of the secret order in which these traditions are preserved, had parts of the accompanying symbolic chart (Fig. 389) tattooed on their throats and chests. This chart is a facsimile of one that was drawn for the author by Hada-ɔüʇse. At the top we see a tree near a river.
This is evidence of the importance of the sun and stars of the Dakota Sioux tribes who once resided in the Ohio Valley and built many of the earthworks aligned to different stars and solar events of the equinoxes and solstices.
