The Athenians, having thus succeeded to the supremacy by the voluntary act of the allies through their hatred of Pausanias, fixed which cities were to contribute money against the barbarian, which ships; their professed object being to retaliate for their sufferings by ravaging the King’s country. Now was the time that the office of “Treasurers for Hellas” was first instituted by the Athenians. These officers received the tribute, as the money contributed was called. The tribute was first fixed at four hundred and sixty talents. The common treasury was at Delos, and the congresses were held in the temple. Their supremacy commenced with independent allies who acted on the resolutions of a common congress. It was marked by the following undertakings in war and in administration during the interval between the Median and the present war, against the barbarian, against their own rebel allies, and against the Peloponnesian powers which would come in contact with them on various occasions. My excuse for relating these events, and for venturing on this digression, is that this passage of history has been omitted by all my predecessors, who have confined themselves either to Hellenic history before the Median War, or the Median War itself. Hellanicus, it is true, did touch on these events in his Athenian history; but he is somewhat concise and not accurate in his dates. Besides, the history of these events contains an explanation of the growth of the Athenian empire. First the Athenians besieged and captured Eion on the Strymon from the Medes, and made slaves of the inhabitants, being under the command of Cimon, son of Miltiades. Next they enslaved Scyros, the island in the Aegean, containing a Dolopian population, and colonized it themselves. This was followed by a war against Carystus, in which the rest of Euboea remained neutral, and which was ended by surrender on conditions. After this Naxos left the confederacy, and a war ensued, and she had to return after a siege; this was the first instance of the engagement being broken by the subjugation of an allied city, a precedent which was followed by that of the rest in the order which circumstances prescribed. Of all the causes of defection, that connected with arrears of tribute and vessels, and with failure of service, was the chief; for the Athenians were very severe and exacting, and made themselves offensive by applying the screw of necessity to men who were not used to and in fact not disposed for any continuous labour. In some other respects the Athenians were not the old popular rulers they had been at first; and if they had more than their fair share of service, it was correspondingly easy for them to reduce any that tried to leave the confederacy. For this the allies had themselves to blame; the wish to get off service making most of them arrange to pay their share of the expense in money instead of in ships, and so to avoid having to leave their homes. Thus while Athens was
