History of the Peloponnesian War

After the Athenians had succeeded in this way to the leadership over the allies, who freely chose them on account of their hatred of Pausanias, they assessed the amount of their contributions, both for the states which were to furnish money for the war against the Barbarians and for those which were to furnish ships, the avowed object being to avenge themselves for what they had suffered by ravaging the King's territory.

And it was then[*](476 B.C.) that the Athenians first established the office of Hellenic treasurers, who received the tribute; for so the contribution of money was termed. The amount of the tribute first assessed was four hundred and sixty talents, and the treasury of the allies was Delos, where the meetings were held in the temple.
