Myth

"One may call the world a myth, in which bodies and things are visible, but souls and minds hidden. Besides, to wish to teach the whole truth about the Gods to all produces contempt in the foolish, because they cannot understand, and lack of zeal in the good, whereas to conceal the truth by myths prevents the contempt of the foolish, and compels the good to practice philosophy."
-Sallstius (Sallust),
"On The Gods And The Cosmos"
