Histories

Not the least proof I have of this is the fact that Leonidas publicly dismissed the seer who attended the expedition, for fear that he might die with them. This was Megistias the Acarnanian, said to be descended from Melampus, the one who told from the sacrifices what was going to happen to them. He was dismissed but did not leave; instead he sent away his only son who was also with the army.

Those allies who were dismissed went off in obedience to Leonidas, only the Thespians and Thebans remaining with the Lacedaemonians. The Thebans remained against their will and desire, for Leonidas kept them as hostages. The Thespians very gladly remained, saying they would not abandon Leonidas and those with him by leaving; instead they would stay and die with them. Their general was Demophilus son of Diadromes.
