Leonidas and his three hundred companions devoted their lives at Thermopylae ; but the education of the infant, the boy, and the man, had prepared, and almost ensured, this memorable sacrifice ; and each Spartan would approve, rather than admire, an act of duty of which himself and eight thousand of his fellow- citizens were equally capable. 1 The great Pompey might inscribe on his trophies, that he had defeated in battle two millions of enemies and reduced fifteen hundred cities from the lake Maeotis to the Red Sea ; 2 but the fortune of Rome flew before his eagles ; the nations were oppressed by their own fears ; and the invincible legions which he commanded had been formed by the habits of conquest and the discipline of ages. 1 It will be a pleasure, not a task, to read Herodotus (1. vii. c. 104, 134, p. 550, 615). The conversation of Xerxes and Demaratus at Thermopylae is one of the most interesting and moral scenes in history. It was the torture of the royal Spartan to behold, with anguish and remorse, the virtue of his country. 2 See this proud inscription in Pliny (Hist. Natur. vii. 27). Few men have more exquisitely tasted of glory and disgrace ; nor could Juvenal (Satir. x.) produce a more striking example of the vicissitudes of fortune and the vanity of human wishes.
