Hitherto the Grecian confederates had sent their deputies to the Peloponnesus. Aristides, instead of naming Athens, which might have excited new jealousies, proposed the sacred Isle of Delos, a spot peculiarly appropriate, since it once had been the navel of the Ionian commerce, as the place of convocation and the common treasury: the temple was to be the senate house. A new distribution of the taxes levied on each state, for the maintenance of the league, was ordained. The objects of the league were both defensive and offensive; first, to guard the Aegaean coasts and the Grecian Isles; and, secondly, to undertake measures for the further weakening of the Persian power. Aristides was elected arbitrator in the relative proportions of the general taxation. In this office, which placed the treasures of Greece at his disposal, he acted with so disinterested a virtue, that he did not even incur the suspicion of having enriched himself, and with so rare a fortune that he contented all the allies. The total, raised annually, and with the strictest impartiality, was four hundred and sixty talents (computed at about one hundred and fifteen thousand pounds). Greece resounded with the praises of Aristides; it was afterward equally loud in reprobation of the avarice of the Athenians. For with the appointment of Aristides commenced the institution of officers styled Hellenotamiae, or treasurers of Greece; they became a permanent magistracy--they were under the control of the Athenians; and thus that people were made at once the generals and the treasurers of Greece. But the Athenians, unconscious as yet of the power they had attained--their allies yet more blind--it seemed now, that the more the latter should confide, the more the former should forbear. So do the most important results arise from causes uncontemplated by the providence of statesmen, and hence do we learn a truth which should never be forgotten--that that power is ever the most certain of endurance and extent, the commencement of which is made popular by moderation. XVIII. Thus, upon the decay of the Isthmian Congress, rose into existence the great Ionian league; and thus was opened to the ambition of Athens the splendid destiny of the empire of the Grecian seas. The pre-eminence of Sparta passed away from her, though invisibly and without a struggle, and, retiring within herself, she was probably unaware of the decline of her authority; still seeing her Peloponnesian allies gathering round her, subordinate and submissive, and, by refusing assistance, refusing also allegiance to the new queen of the Ionian league. His task fulfilled, Aristides probably returned to Athens, and it was at this time and henceforth that it became his policy to support the power of Cimon against the authority of Themistocles [140]. To that eupatrid, joined before with himself, was now intrusted the command of the Grecian fleet.
