In view of all this, it is suggested that a cult of the Sun deity may have been introduced to a peyote-using proto-Huichol people in comparatively recent times, probably together with agriculture itself, and that this cult of the Sun god, with its strong emphasis on sacrifice, may have been accompanied by a datura cult. While the Sun god could be integrated successfully (though with acertain degree of ambivalence) into the existing family of deities because of his importance to the success of agriculture, datura could neither co-exist with peyote nor replace it. For we may assume from the contemporary accounts that peyote held much the same position in the religion and world view of the hunters of the north-central deserts as it does today among the Huichols who may well be their direct descendents. If we suppose that the Kieri myths have historical validity, it is this interpretation which to us seems most acceptable.
