Pronunciation

  • 5th-century BC Attic: /mys.tɛ̌ː.ri.on/[1]
  • 4th-century AD Koine: /mysˈti.ri.on/[1]
  • 10th-century Byzantine: /mysˈti.ri.on/[1]

Forms

μῠστήρῐον (mustḗrion) n (genitive μῠστηρῐ́ου); second declension[1]

Etymology

It is a derivative from Ancient Greek μύστης (mústēs, “initiate”), which goes with μυέω (muéō, “to initiate”) and μύω (mū́ō, “to close (the eyes or lips)”).[2][3][4] Beekes takes the initiate to be “one who shuts his eyes”, in contrast with the ἐπόπτης (epóptēs, “watcher”) of the highest grade.[2] The further origin of the verb is uncertain: Beekes gives Proto-Indo-European *meus-, *meuH- (“to shut”) with a query, while Chantraine links it with the sound μῦ (mû) made with closed lips.[2][5]

A derivation from a Semitic word for “hiding place”, proposed in the 19th century, is rejected.[6] Athenaeus records a pun of the tyrant Dionysius, who called mouse-holes “mysteries” as if from μῦς (mûs, “mouse”) and τηρέω (tēréō, “to watch”).[3]

Earliest recorded meaning

Heraclitus is the first to speak of the mysteries, the secret rites, and Herodotus uses the word of the mysteries of the Cabiri on Samothrace.[3][7][8]

Semantic evolution

Mostly in the plural, the word named secret rites of initiation, above all the Eleusinian mysteries of Demeter, with their Greater and Lesser celebrations.[3][8] It also meant the sacred objects carried in them, and Aristophanes has the proverb of the donkey that carries the mysteries, said of an overloaded beast.[3] By extension it came to mean any secret: Plato and Menander use it so, and the doctors called a remedy they kept to themselves their “mystery”.[3]

The Septuagint, in Daniel and the wisdom books, uses it for secrets, including political and military ones, and for God's hidden plans.[9][4] In the New Testament it is a secret of God, now revealed, as in “the mystery of the kingdom” and Paul's “mystery of the Gospel”.[8][3][10] Hellenistic Christian Greek came to use it for the sacraments.[11]

It passed into Latin as mystērium, and through Latin and Old French it gave the English word mystery.[1][12] Modern Greek μυστήριο (mystírio) means a sacrament of the Church and the ancient mysteries, and, as a semantic loan from French mystère, a medieval mystery play.[11]
