Etymology

It is an agent noun in -της (-tēs), formed on μυέω (muéō, “to initiate”), itself from Ancient Greek μύω (múō, “to close (the eyes or lips)”).[1][2][3] The name probably meant “one who closes his eyes”, as opposed to ἐπόπτης (epóptēs), the “watcher” who had reached the highest grade of the mysteries;[2] the CGL and Babiniotis add the alternative that the initiate closed his lips, to keep the secret.[4][3] The origin of the verb is uncertain: its root may be Proto-Indo-European *meus- or Proto-Indo-European *meuH-, and a link with Hittite munnae-zi (“to hide”) has been proposed.[2]

Earliest recorded meaning

The first record is in a fragment of Heraclitus, in the 6th–5th century BC, who speaks of the “initiates”.[5][6][3]

Semantic evolution

The word meant one initiated into mysteries, above all the Eleusinian ones;[2] Xenophon mentions the herald of the initiates, and Aristophanes speaks of the dances of initiates.[6][4] With a genitive it named an initiate of a particular god, as in Euripides' “initiate of Idaean Zeus”.[6][4] Later it was a title of Dionysus and of Apollo, and a lamp that lit a night festival could be called a “mystic” lamp.[6] The Septuagint uses it once, in the Book of Wisdom.[7]

Latin borrowed it as mystes.[8] In medieval Greek it meant an initiate or follower, as in “initiate of Christ”, and also a confidant.[9] Modern Greek μύστης (místis) is learned: an initiate, the founder of a religion, or a deep connoisseur of a science or an art.[10]
