"My friend," answered the Persian, "man cannot avert what God has decreed. No one will believe the revelation, sure though it be. Many of us Persians know this well, and are here serving only under the bond of necessity. And truly this is the most hateful of all human sufferings, to be full of knowledge, and at the same time to have no power over any result." Not long had the lukewarm Persians to wait for their foes. Soon the army of Greece appeared, and, seeing their enemy encamped along the little river Asopus in the plain, took post on the mountain declivity above. Here they were not suffered to rest in peace. The powerful Persian cavalry, led by Masistius, the most distinguished officer in the army, broke like a thunderbolt on the Grecian ranks. The Athenians and Megarians met them, and a sharp and doubtful contest ensued. At length Masistius fell from his wounded horse and was slain as he lay on the ground. The Persians fought with fury to recover his body, but were finally driven back, leaving the corpse of their general in the hands of the Greeks. This event had a great effect on both armies. Grief assailed the army of Mardonius at the loss of their favorite general. Loud wailings filled the camp, and the hair of men, horses, and cattle was cut in sign of mourning. The Greeks, on the contrary, were full of joy. The body of Masistius, a man of great stature, and clad in showy armor, was placed in a cart and paraded around the camp, that all might see it and rejoice. Such was their confidence at this defeat of the cavalry, which they had sorely feared, that Pausanias broke up his hill camp and marched into the plain below, where he took station in front of the Persian host, only the little stream of the Asopus dividing the two hostile armies. And here for days they lay, both sides offering sacrifices, and both obtaining the same oracle,--that the side which attacked would lose the battle, the side which resisted would win. Under such circumstances neither side cared to attack, and for ten days the armies lay, the Greeks much annoyed by the Persian cavalry, and having their convoys of provisions cut off, yet still waiting with unyielding faith in the decision of the gods. Mardonius at length grew impatient. He asked his officers if they knew of any prophecy saying that the Persians would be destroyed in Greece. They were all silent, though many of them knew of such prophecies. "Since you either do not know or will not tell," he at length said, "I well know of one. There is an oracle which declares that Persian invaders shall plunder the temple of Delphi, and shall afterwards all be destroyed. Now we shall not go against that temple, so on that ground we shall not be destroyed. Doubt not, then, but rejoice, for we shall get the better of the Greeks." And he gave orders to prepare for battle on the morrow, without waiting longer on the sacrifices.
