65. Cleomenes then, being anxious to take vengeance on him, concerted matters with Leotychides the son of Menares, the son of Agis, who was of the same house as Demaratos, under condition that if he should set him up as king instead of Demaratos, he would go with him against the Eginetans. Now Leotychides had become a bitter foe of Demaratos on account of this matter which follows:--Leotychides had betrothed himself to Percalos the daughter of Chilon son of Demarmenos; and Demaratos plotted against him and deprived Leotychides of his marriage, carrying off Percalos himself beforehand, and getting her for his wife. Thus had arisen the enmity of Leotychides against Demaratos; and now by the instigation of Cleomenes Leotychides deposed against Demaratos, saying that he was not rightfully reigning over the Spartans, not being a son of Ariston: and after this deposition he prosecuted a suit against him, recalling the old saying which Ariston uttered at the time when his servant reported to him that a son was born to him, and he reckoning up the months denied with an oath, saying that it was not his. Taking his stand upon this utterance, Leotychides proceeded to prove that Demaratos was not born of Ariston nor was rightfully reigning over Sparta; and he produced as witnesses those Ephors who chanced then to have been sitting with Ariston in council and to have heard him say this.. 66. At last, as there was contention about those matters, the Spartans resolved to ask the Oracle at Delphi whether Demaratos was the son of Ariston. The question then having been referred by the arrangement of Cleomenes to the Pythian prophetess, thereupon Cleomenes gained over to his side Cobon the son of Aristophantos, who had most power among the Delphians, and Cobin persuaded Perialla the prophetess of the Oracle 53 to say that which Cleomenes desired to have said. Thus the Pythian prophetess, when those who were sent to consult the god asked her their question, gave decision that Demaratos was not the son of Ariston. Afterwards however these things became known, and both Cobon went into exile from Delphi and Perialla the prophetess of the Oracle was removed from her office.
