Strabo 9:4

Ephoros says that the Thracians, after making a treaty with the Boiotians, attacked them by night when they, thinking that peace had been made, were encamping rather carelessly. When the Boiotians frustrated the Thracians and at the same time made the charge that they were breaking the treaty, the Thracians asserted that they had not broken it, for the treaty said “during the day” but they had made the attack at night. This is where the proverb, “Thracian pretense” comes from.

The Pelasgians, when the war was still going on, went to consult the oracle, as the Boiotians did also. Now Ephoros says he is unable to relate the oracular response that was given to the Pelasgians, but the prophetess replied to the Boiotians that they would prosper if they committed sacrilege. The messengers who were sent to consult the oracle, suspecting that the prophetess responded in this way out of favour for the Pelasgians (because of her kinship with them, for in fact the temple was also Pelasgian from the outset), seized the woman and threw her upon a burning pile. They considered that, whether she had acted falsely or had not, they were right in either case, since, if she uttered a false oracle, she had her punishment, but if she did not act falsely, they had only obeyed the order of the oracle. Now those in charge of the temple, he says, did not approve of putting to death without trial – and that too in the temple – the men who did this. Therefore they brought them to trial, and summoned them before the priestesses, who were also the prophetesses, being the two survivors of the three. But when the Boiotians said that it was nowhere lawful for women to act as judges, they chose an equal number of men in addition to the women. Now the men, he says, voted for acquittal, but the women for conviction. Since the votes cast were equal, those for acquittal prevailed. As a result, prophecies are uttered at Dodona by men to Boiotians only. The prophetesses, however, explain the oracle to mean that the God ordered the Boiotians to steal the tripods​ and take one of them to Dodona every year. They actually do this, for they always​ take down one of the dedicated tripods by night and cover it up with garments, and secretly, as it were, carry it to Dodona.
