"For the past fifty years at least, Western scholars have approached the study of myth from a viewpoint markedly different from, let us say, that of the nineteenth century. Unlike their predecessors, who treated myth in the usual meaning of the word, that is, as "fable," "invention," "fiction," they have accepted it as it was understood in archaic societies, where, on the contrary, "myth" means a "true story" and, beyond that, a story that is a most precious possession because it is sacred, exemplary, significant. This new semantic value given the term "myth" makes its use in contemporary parlance somewhat equivocal. Today, that is, the word is employed both in the sense of "fiction" or "illusion" and in that familiar especially to ethnologists, sociologists, and historians of religions, the sense of "sacred tradition, primordial revelation, exemplary model." … the Greeks steadily continued to empty mythos of all religious and metaphysical value. Contrasted both with logos and, later, with historia, mythos came in the end to denote "what cannot really exist." On its side, Judaeo-Christianity put the stamp of "falsehood" and "illusion" on whatever was not justified or validated by the two Testaments."
