These faithful few were soon encouraged by a prodigy. The sacred arms, kept in the temple's inmost cell, and which no mortal hand dared touch, were seen lying before the temple door, as if Apollo was prepared himself to use them. As the Persians advanced by a rugged path under the steep cliffs of Mount Parnassus, and reached the temple of Athené Pronæa, a dreadful peal of thunder rolled above their affrighted heads, and two great crags, torn from the mountain's flank, came rushing down with deafening sound, and buried many of them beneath their weight. At the same time, from the temple of Athené, came the Greek shout of war.

In a panic the invaders turned and fled, hotly pursued by the few Delphians, and, so the story goes, by two armed men of superhuman size, whose destructive arms wrought dire havoc in the fleeing host. And thus, as we are told, did the god preserve his temple and his wealth.

But no god guarded the road to Athens, and at length Xerxes and his army reached that city,—four months after they had crossed the Hellespont. It was an empty city they found. The few defenders of the Acropolis—a craggy hill about one hundred and fifty feet high—made a vigorous defence, for a time keeping the whole Persian army at bay. But some Persians crept up a steep and unguarded part of the wall, entered the citadel, and soon all its defenders were dead, and its temples and buildings in flames.

While all this was going on, the Grecian fleet lay but a few miles away, in the narrow strait between the isle of Salamis and the Attic coast, occupying the little bay before the town of Salamis, from which narrow channels at each end led into the Bay of Eleusis to the north and the open sea to the south. In front rose the craggy heights of Mount Ægaleos, over which, only five miles away, could be seen ascending the lurid smoke of blazing Athens. It was a spectacle calculated to infuriate the Athenians, though not one to inspire them with courage and hope.

The fleet of Greece consisted of three hundred and sixty-six ships in all, of which Athens supplied two hundred, while the remainder came in small numbers from the various Grecian states. The Persian fleet, despite its losses by storm, far outnumbered that of Greece, and came sweeping down the Attic coast, confident of victory, while the great army marched southward over Attic land.

And now two councils of war were held,—one by the Persian leaders, one by the Greeks. The fleet of Xerxes, probably still a thousand ships strong, lay in the Bay of Phalerum, a few miles from Athens; and hither the king, having wrought his will on that proud and insolent city, came to the coast to inspect his ships of war and take counsel as to what should next be done.

Here, before his royal throne, were seated the kings of Tyre and Sidon, and the rulers of the many other nations represented in his army. One by one they were asked what should be done. "Fight," was the general reply; "fight without delay." Only one voice gave different advice, that of Queen Artemisia of Halicarnassus. She advised Xerxes to march to the isthmus of Corinth, saying that then all the ships of the Peloponnesus would fly to defend their own homes, and the fleet of Greece would thus be dispersed. Xerxes heard her with calmness, but declined to take her prudent advice. The voice of the others and his own confidence prevailed, and orders were given for the fleet to make its attack the next day.

The almost unanimous decision of this council, over which ruled the will of an autocratic king, was very different from that which was reached by the Greeks, in whose council all who spoke had equal authority. The fleet had come to Salamis to aid the flight of the Athenians. This done, it was necessary to decide where it was best to meet the Persian fleet. Only the Athenians, under the leadership of Themistocles, favored remaining where they were. The others perceived that if they were defeated here, escape would be impossible. Most of them wished to sail to the isthmus of Corinth, to aid the land army of the Peloponnesians, while various other plans were urged.

While the chiefs thus debated news came that Athens and the Acropolis were in flames. At once some of the captains left the council in alarm, and began hastily to hoist sail for flight. Those that remained voted to remove to the isthmus, but not to start till the morning of the next day.
