The term “Mystery” derives from Latin mysterium, from Greek mysterion (usually as the plural mysteria μυστήρια), in this context meaning “secret rite or doctrine.” An individual who followed such a “Mystery” was a mystes, “one who has been initiated,” from myein “to close, shut,” a reference to secrecy (closure of “the eyes and mouth”)[4]:56 or that only initiates were allowed to observe and participate in rituals. The Mysteries were thus cults in which all religious functions were closed to the uninitiated and for which the inner-working of the cult were kept secret from the general public.
