Book 8
14.11
Myrtilus himself, too, was in love with Hippodameia, but his courage failing him he shrank from the competition and served Oenomaus as his charioteer. At last, it is said, he proved a traitor to Oenomaus, being induced thereto by an oath sworn by Pelops that he would let him be with Hippodameia for one night. So when reminded of his oath Pelops threw him out of the ship. The people of Pheneus say that the body of Myrtilus was cast ashore by the tide, that they took it up and buried it, and that every year they sacrifice to him by night as to a hero.
14.12
It is plain that Pelops did not make a long coasting voyage, but only sailed from the mouth of the Alpheius to the harbor of Elis. So the Sea of Myrto is obviously not named after Myrtilus, the son of Hermes, as it begins at Euboea and reaches the Aegaean by way of the uninhabited island of Helene. I think that a probable account is given by the antiquarians of Euboea, who say that the sea is named after a woman called Myrto.
15.1
The people of Pheneus have also a sanctuary of Demeter, surnamed Eleusinian, and they perform a ritual to the goddess, saying that the ceremonies at Eleusis are the same as those established among themselves. For Naus, they assert, came to them because of an oracle from Delphi, being a grandson of Eumolpus. Beside the sanctuary of the Eleusinian has been set up Petroma, as it is called, consisting of two large stones fitted one to the other.
15.2
When every other year they celebrate what they call the Greater Rites, they open these stones. They take from out them writings that refer to the rites, read them in the hearing of the initiated, and return them on the same night. Most Pheneatians, too, I know, take an oath by the Petroma in the most important affairs.
