64. Thus those at Salamis, after having skirmished with one another in speech, were making preparations for a sea-fight there, since Eurybiades had so determined: and as day was coming on, at the same time when the sun rose there was an earthquake felt both on the land and on the sea: and they determined to pray to the gods and to call upon the sons of Aiacos to be their helpers. And as they had determined, so also they did; for when they had prayed to all the gods, they called Ajax and Telamon to their help from Salamis, where the fleet was, 38 and sent a ship to Egina to bring Aiacos himself and the rest of the sons of Aiacos. 65. Moreover Dicaios the son of Theokydes, an Athenian, who was an exile and had become of great repute among the Medes at this time, declared that when the Attic land was being ravaged by the land-army of Xerxes, having been deserted by the Athenians, he happened then to be in company with Demaratos the Lacedemonian in the Thriasian plain; and he saw a cloud of dust going up from Eleusis, as if made by a company of about thirty thousand men, and they wondered at the cloud of dust, by what men it was caused. Then forthwith they heard a sound of voices, and Dicaios perceived that the sound was the mystic cry Iacchos; but Demaratos, having no knowledge of the sacred rites which are done at Eleusis, asked him what this was that uttered the sound, and he said: "Demaratos, it cannot be but that some great destruction is about to come to the army of the king: for as to this, it is very manifest, seeing that Attica is deserted, that this which utters the sound is of the gods, and that it is going from Eleusis to help the Athenians and their allies: if then it shall come down in the Peloponnese, there is danger for the king himself and for the army which is upon the mainland, but if it shall direct its course towards the ships which are at Salamis, the king will be in danger of losing his fleet. This feast the Athenians celebrate every year to the Mother and the Daughter; 39 and he that desires it, both of them and of the other Hellenes, is initiated in the mysteries; and the sound of voices which thou hearest is the cry Iacchos which they utter at this feast." To this Demaratos said: "Keep silence and tell not this tale to any other man; for if these words of thine be reported to the king, thou wilt surely lose thy head, and neither I nor any other man upon earth will be able to save thee: but keep thou quiet, and about this expedition the gods will provide." He then thus advised, and after the cloud of dust and the sound of voices there came a mist which was borne aloft and carried towards Salamis to the camp of the Hellenes: and thus they learnt (said he) that the fleet of Xerxes was destined to be destroyed. Such was the report made by Dicaios the son of Theodykes, appealing to Demaratos and others also as witnesses.
