Pausanias Description of Greece 4.26.6

[6] To Epameinondas it seemed in no way easy to found a city that could resist the Lacedaemonians, nor could he discover where in the land to build it. For the Messenians refused to settle again in Andania and Oechalia, because their disasters had befallen them when they dwelled there. To Epameinondas in his difficulty it is said that an ancient man, closely resembling a priest of Demeter, appeared in the night and said: “My gift to thee is that thou shalt conquer whomsoever thou dost assail; and when thou dost pass from men, Theban, I will cause thy name to be unforgotten and give thee glory. But do thou restore to the Messenians their fatherland and cities, for now the wrath of the Dioskouroi against them hath ceased.”
