Like Pausanias before him, Admiral Lysander became intoxicated with success. A very little liberty and luxury was enough to bring giddiness to the ascetic heads of Sparta. Lysander began to think revolutionary thoughts of a Sparta where men could be rich and free like the rest of the world. And the infection spread. Sparta was now earning a thousand talents a year from her empire, and though money was still forbidden at home, and though Sparta had as yet absolutely no coinage of her own, private Spartans were unquestionably getting rich quickly. A rich Spartan was a horrid anomaly: there was nothing that money could buy in Laconia except land. Hence family estates began to change hands faster, and the class of landless, therefore voteless, men of Spartan blood rapidly multiplied. It was Sparta’s boast that she alone in all Greece had never suffered a revolution. She never came so near it as on the present occasion, when Lysander with his riches was trying to subvert the Lycurgean constitution by bribing the Delphic oracle, and the discontented Inferiors at home were planning a secret rebellion. Both failed: the conspiracy of Cinadon was detected by the vigilant Ephors and ruthlessly crushed, while Lysander in playing the part of king-maker unwittingly made a king who was his equal in ability. Very soon the conqueror of Athens found himself unnecessary to Sparta, and had to submit to the indignity of being tried and pardoned.
The new king was Agesilaus, whose long and important career was the subject of many biographies. He it was who pointed the path of glory to Alexander by revealing the utter incapacity of the Persians to guard their treasures. For Sparta had quickly fallen out with the satraps, and Agesilaus marched about the Phrygian and Lydian coasts gathering plunder with very little difficulty. One of the biographers of Agesilaus was his friend and admirer Xenophon, who was concerned in a great adventure which likewise served to betray the weakness of the Persian empire.
