73. These then having been thus laid in bonds were put to death; and the Athenians after this sent for Cleisthenes to return, and also for the seven hundred families which had been driven out by Cleomenes: and then they sent envoys to Sardis, desiring to make an alliance with the Persians; for they were well assured that the Lacedemonians and Cleomenes had been utterly made their foes. So when these envoys had arrived at Sardis and were saying that which they had been commanded to say, Artaphrenes the son of Hystaspes, the governor of Sardis, asked what men these were who requested to be allies of the Persians, and where upon the earth they dwelt; and having heard this from the envoys, he summed up his answer to them thus, saying that if the Athenians were willing to give earth and water to Dareios, he was willing to make alliance with them, but if not, he bade them begone: and the envoys taking the matter upon themselves said that they were willing to do so, because they desired to make the alliance. 74. These, when they returned to their own land, were highly censured: and Cleomenes meanwhile, conceiving that he had been outrageously dealt with by the Athenians both with words and with deeds, was gathering together an army from the whole of the Peloponnese, not declaring the purpose for which he was gathering it, but desiring to take vengeance on the people of the Athenians, and intending to make Isagoras despot; for he too had come out of the Acropolis together with Cleomenes. Cleomenes then with a large army entered Eleusis, while at the same time the Boeotians by agreement with him captured Oinoe and Hysiai, the demes which lay upon the extreme borders of Attica, and the Chalkidians on the other side invaded and began to ravage various districts of Attica. The Athenians then, though attacked on more sides than one, thought that they would remember the Boeotians and Chalkidians afterwards, and arrayed themselves against the Peloponnesians who were in Eleusis. 75. Then as the armies were just about the join battle, the Corinthians first, considering with themselves that they were not acting rightly, changed their minds and departed; and after that Demaratos the son of Ariston did the same, who was king of the Spartans as well as Cleomenes, though he had joined with him in leading the army out from Lacedemon and had not been before this at variance with Cleomenes. In consequence of this dissension a law was laid down at Sparta that it should not be permitted, when an army went out, that both the kings should go with it, for up to this time both used to go with it, and that as one of the kings was set free from service, so one of the sons of Tyndareus 64 also should be left behind; for before this time both of these two were called upon by them for help and went with the armies.
