THERMOPYLAE. 155

had inscriptions graven on the rocks by all the water- ing-places, exhorting the Ionian Greeks now in the service of Persia to desert. If this had no effect on those to whom they were addressed, it would at any rate make them objects of suspicion to the Persians. Then the Greeks sailed away the Corinthians first, the Athenians, as became them, last. While the Persian sailors and marines were wasting the north of Eubcsa, a herald came from Xerxes order- ing a day's leave ashore to be given, that the crews might view the field of Thermopylae. On the Greek side were four thousand bodies in a heap, which the king pretended were all Spartans or Thespians; on his side lay about a thousand, scattered all over the field. The rest of the Persians had been carefully buried beforehand ; but the trick deceived nobody. The Persian army now advanced and ravaged Phocis, and on the farther frontier parted into two divisions, the larger entering the friendly territory of Boeotia, and making for Athens the smaller proceeding to- wards Delphi. Xerxes was well instructed as to the wealth of Apollo's temple, and must have known by heart all the costly offerings that Croesus had made. The Delphians in dismay consulted their oracle : the god replied that "he could protect his own." Just when the enemy reached the ascent to the temple, a thunderstorm burst forth, and great rocks came rolling down the steep of Parnassus. The Persians fled, and the Delphians, assisted apparently by two supernatural warriors, emerged from their hiding-places and slew the hindermost. The priests of Apollo were doubtless adepts in the machinery of the stage.
