"The Greek word muthos means formulated speech, whether it be a story, a dialogue, or the enunciation of a plan.  So muthos belongs to the domain of legein ["to speak"], [...] and does not originally stand in contrast to logoi, a term that has a closely related semantic significance and that is concerned with the different forms of what is said.  [...]  Between the eighth and fourth centuries B.C.[E.], a whole series of interrelated conditions caused a multiplicity of differentiations, breaks, and internal tensions with in the mental universe of the Greeks that were responsible for distinguishing the domain of myth from other domains:  The concept of myth peculiar to classical antiquity thus became clearly defined through the setting up of an opposition between muthos and logos, henceforth seen as separate and contrasting terms."—Thank you, Jean-Pierre Vernant for Myth and Society in Ancient Greece, Zone Books, 1990, p.203-204.  Thank you, Chris & Anna Celenza for access to the library from which this book was borrowed.
