XI. After this the people espoused the cause of Agis, while the rich begged Leonidas not to desert them, and by their entreaties prevailed upon the senators, who had the power of originating all laws, to throw out the rhetra by a majority of only one vote. Lysander, who was still one of the Ephors, now proceeded to attack Leonidas, by means of a certain ancient law, which forbade any descendant of Herakles to beget children by a foreign wife, and which bade the Spartans put to death any citizen who left his country to dwell in a foreign land. He instructed his adherents to revive the memory of this law, and threaten Leonidas with its penalties, while he himself with the other Ephors watched for the sign from heaven. This ceremony is conducted as follows:--Every ninth year the Ephors choose a clear moonless night, and sit in silence watching the heavens. If a star shoots across the sky, they conclude that the kings must have committed some act of impiety, and they suspend them from their office, until they were absolved by a favourable oracle from Delphi or Olympia. Lysander now declared that he had beheld this sign, and impeached Leonidas, bringing forward witnesses to prove that he had two children born to him by an Asiatic wife, the daughter of one of the lieutenants of Seleukus, and that having quarrelled with his wife and become hated by her he had unexpectedly returned home, and in default of a direct heir, had succeeded to the throne. At the same time Lysander urged Kleombrotus, the son-in-law of Leonidas, who was also of the royal family, to claim the throne for himself. Leonidas, terrified at this, took sanctuary in the temple of Athena of the Brazen House, and was joined there by his daughter, who left her husband Kleombrotus. When the trial came on, Leonidas did not appear in court, he was removed from the throne, and Kleombrotus was appointed in his stead.
