 The ancient Greek word "mystery" () means "mystery or secret rite" and is related with the verb "mueō" (), which means initiation into the mysteries, and the noun "mustēs" (), which means one initiated.The word "mustikós" () means "connected with the mysteries", or "private, secret" (as in Modern Greek).The Mysteries are related to a myth concerning Demeter, the goddess of agriculture and fertility as recounted in one of the Homeric Hymns (c. 650 BC).
