Themistocles, being at a loss, and not able to draw the people over to his opinion by any human reason, set his machines to work, as in a theatre, and employed prodigies and oracles. The serpent of Athena, kept in the inner part of her temple, disappeared; the priests gave it out to the people and declared, by the suggestion of Themistocles, that the goddess had left the city, and taken her flight before them towards the sea. And he often urged them with the oracle which bade them "trust to walls of wood," showing them that walls of wood could signify nothing else but ships; and that the island of Salamis was termed in it not miserable or unhappy, but had the epithet of divine, for that it should one day be associated with a great good fortune of the Greeks. At length his opinion prevailed, and he obtained a decree that the city should be committed to the protection of Athena, "queen of Athens"; that they who were of age to bear arms should embark, and that each should see to sending away his children, women, and slaves where he could. This decree being confirmed, most of the Athenians removed their parents, wives, and children to Troezen, where they were received with eager good-will by the Troezenians, who passed a vote that they should be maintained at the public charge. Among the great actions of Themistocles at this crisis, the recall of Aristides was not the least, for, before the war, he had been ostracized by the party which Themistocles headed, and was in banishment; but now, perceiving that the people regretted his absence, and were fearful that he might go over to the Persians to revenge himself, and thereby ruin the affairs of Greece, Themistocles proposed a decree that those who were banished for a time might return again, to give assistance by word and deed to the cause of Greece with the rest of their fellow citizens.
