Themistocles (19.1-19.2)

After the great achievements now described, he straightway undertook to rebuild and fortify the city,—as Theopompus relates, by bribing the Spartan Ephors not to oppose the project; but as the majority say, by hoodwinking them. He came with this object to Sparta, ostensibly on an embassy, and when the Spartans brought up the charge that the Athenians were fortifying their city, and Polyarchus was sent expressly from Aegina with the same accusation,

he denied that it was so, and bade them send men to Athens to see for themselves, not only because this delay would secure time for the building of the wall, but also because he wished the Athenians to hold these envoys as hostages for his own person. And this was what actually happened. When the Lacedaemonians found out the truth they did him no harm, but concealed their displeasure and sent him away. After this he equipped the Piraeus, because he had noticed the favorable shape of its harbors, and wished to attach the whole city to the sea; thus in a certain manner counteracting the policies of the ancient Athenian kings.
