(Side A) To good fortune! During the presidency of Akrodemos, son of Dioteimos, the Magnesian people consulted the god concerning a sign which happened. For an image of Dionysos was visible in a tree that had been struck by lightening and blown by a heavy wind. What does this mean? Why does it continue? In order to find this out, oracular messengers named Hermonax, son of Epikratos, and Aristarchos, son of Diodoros, were sent to Delphi.
The god answered:
Magnesians, who obtained the holy city on the Maeander river and defend our possessions: you came to hear from my mouth what the appearance of Bakchos, seen lying by a bush, means. He was made manifest while still a youth, when the clear‑aired city was founded but temples were not yet built for Dionysos.
Now do the following, oh extremely strong people. Dedicate temples which delight in the wand of the god and appoint a perfect and sacred priest. Come onto Thebes’ holy ground, so that you may receive maenads who are descendants of Ino, Kadmos’ daughter. They will give to you good rites and customs and will consecrate Bacchic associations (thiasoi) in the city.
According to the oracle and by means of the oracular messengers, three maenads named Kosko, Baubo, and Thettale were sent from Thebes. Kosko gathered together the association of Platanistenai, Baubo the association before the city, and Thettale the association of Kataibatai. They died and were buried by the Magnesians. Kosko lies in Koskobounos district, Baubo in Tabarnis district, and Thettale near the theatre.
(Side B) Apollonios Mokolles, ancient initiate, dedicated this ancient oracle to the god Dionysos, inscribing it upon a plaque together with the altar.
