1. Herodotus,VIII. 135 (trans. A.D. Godley) (The Loeb Classical Library)

"But at this time there happened, as the Thebans say, a thing at which I marvel greatly. It would seem that this man Mys of Europus came in his wanderings among the places of divination to the precinct of Ptoan Apollo. This temple is called Ptoum, and belongs to the Thebans ; it lies by a hill, above the lake Copais, very near to the town Acraephia. When the man called Mys entered into this temple, three men of the town following him that were chosen on the state’s behalf to write down the oracles that should be given, straightway the diviner prophesied in a foreign tongue. The Thebans that followed him stood astonied to hear strange language instead of Greek, and knew not what this present matter might be; but Mys of Europus snatched from them the tablet that they carried and wrote on it that which was spoken by the prophets,, saying that the words of the oracle were Carian; and having written all down he went away back to Thessaly."
