Several years had passed in unbroken peace when a trivial matter and an obscure man threw all in disorder again. Naxos, the largest of the Cyclades, was powerful at that time, ruling over several islands, possessing a considerable navy and able to place in the field eight thousand hoplites. Unfortunately, like every other Grecian state, Naxos was divided into two factions, the popular and the aristocratic. This latter destroyed itself by an unpardonable crime, similar to that of which Lucretia was victim about the same time in Rome. Sent into exile, they proposed to Aristagoras, Histiæus’ son-in-law and, in his absence, tyrant of Miletus, to take them back to their island. He acceded readily, beholding in fancy the Cyclades, possibly also Eubœa as already under his dominion. But unable to accomplish such an enterprise without help, he succeeded in interesting the satrap of Sardis, Artaphernes, who placed at his disposal a fleet of two hundred ships commanded by Megabates. This Persian rebelled at being under the orders of a Greek and to avenge a slight received in a quarrel that broke out between them, sent information to the Naxians. The success of the expedition depended on secrecy; this once destroyed, it was bound to fail. Aristagoras held to the project four months, spending his own treasure as well as that given him for the enterprise by the king. He feared being obliged to make good this loss, and decided that revolt offered a preferable alternative, in which choice he was aided by the secret instigations of Histiæus. The army he had led before Naxos was still united, and forming part of it were all the tyrants of the cities on the Asiatic coast. These he seized and sent back to their respective cities where they were placed under sentence of death or exile, then established democracy everywhere (499 B.C.). After these deeds, finding it necessary to attach some powerful ally to his cause, he visited Lacedæmon. Cleomenes, its king, questioned him as to the distance of the Persian capital from the sea. “A three months’ march,” replied Aristagoras. “In that case you will leave this place to-morrow,” said the king, “it would be folly to propose to Lacedæmonians to put a three months’ march between themselves and the sea.” Aristagoras tried to bribe him to consent; but for once Spartan virtue was incorruptible and the Ionian went on to Athens. Given permission to speak in the assembly, he described the riches of Persia, and laid stress on the advantage the Greeks would have over a foe to whom the use of spear and shield was unknown, and finally adduced the fact that Miletus was a colony of Athens. The Athenians had more than one grievance against the Persians—the refuge given to Hippias, and the order to recall the tyrant received as a reply to their remonstrances. Aristagoras had little difficulty in persuading them to assure their own safety by carrying the war with which they were menaced over into the enemy’s country, they also believing doubtless that the matter was but a private quarrel between the satrap and Aristagoras. They decreed to the envoy twenty vessels to which were added five triremes from Eretria, this state thus repaying the aid it had formerly received from Miletus in its war against Chalcis. The allies proceeded to Ephesus and thence to Sardis, which they took and pillaged. The houses were thatched with reeds, and, a soldier accidentally setting fire to one of the roofs, the entire city, with the exception of the citadel to which Artaphernes had retired, was consumed, together with the temple of Cybele, venerated as deeply by the Persians as by the Lydians (498). Artaphernes meanwhile had recalled the army that was besieging Miletus, and from all sides gathered the provincial troops; the Athenians began to think of retreat. A defeat they suffered near Ephesus, possibly also treason among themselves, completed their dissatisfaction. They boarded their ships and returned to Athens, leaving their allies to extricate themselves from the difficulty in which they were placed as best they could.
