The Persians had forced their way into Greece. Nothing could check their further advance, so the mighty army swept southward. The first place of note on their way to Athens was Delphi, the site of the sacred temple, where great treasures were stored.

The Greeks knew that the Persians did not worship the same gods, and feared that they might rob the temple: so they now eagerly questioned the oracle, to find out whether they should not all assemble there in its defense.

To their surprise, the oracle proudly replied, “The gods will take care of their own,” and bade them rather use their strength to defend their own homes.

The Persians marched into the rocky gorge leading to the temple at Delphi, but just as they were entering the valley a terrible thunderstorm broke forth. The darkness became so great that the soldiers lost their way. The rocks rolled and crashed down upon them; and the soldiers, filled with dread, beat a hasty retreat, and never again dared venture into this valley.

In the mean while the Greek fleet at Artemisium had held the Persian vessels at bay, until news was brought of the death of Leonidas, and the passage of Thermopylae. Then the Greeks sailed as fast as they could toward Athens, knowing that they would be needed there to defend the city.

The various allies, sure that it would be quite useless to try to defend the northern part of Greece any longer, retreated into the Peloponnesus, and, hoping to prevent the Persians from entering there, hastily began to build a huge wall all across the Isthmus of Corinth, which is only about five miles wide.
