At the assembly of the Amphictyons, the Lacedaemonian delegates moved that all those states who had not joined in the anti-Persic confederacy should be expelled the council. Under this popular and patriotic proposition was sagaciously concealed the increase of the Spartan authority; for had the Thessalians, Argives, and Thebans (voices ever counter to the Lacedaemonians) been expelled the assembly, the Lacedaemonian party would have secured the preponderance of votes, and the absolute dictation of that ancient council. [132] But Themistocles, who seemed endowed with a Spartan sagacity for the foiling the Spartan interests, resisted the proposition by arguments no less popular. He represented to the delegates that it was unjust to punish states for the errors of their leaders--that only thirty-one cities had contributed to the burden of the war, and many of those inconsiderable--that it was equally dangerous and absurd to exclude from the general Grecian councils the great proportion of the Grecian states. The arguments of Themistocles prevailed, but his success stimulated yet more sharply against him the rancour of the Lacedaemonians; and, unable to resist him abroad, they thenceforth resolved to undermine his authority at home. XI. While, his danger invisible, Themistocles was increasing with his own power that of the state, the allies were bent on new enterprises and continued retribution. From Persia, now humbled and exhausted, it was the moment to wrest the Grecian towns, whether in Europe or in Asia, over which she yet arrogated dominion--it was resolved, therefore, to fit out a fleet, to which the Peloponnesus contributed twenty and Athens thirty vessels. Aristides presided over the latter; Pausanias was commander-in-chief; many other of the allies joined the expedition. They sailed to Cyprus, and reduced with ease most of the towns in that island. Thence proceeding to Byzantium, the main strength and citadel of Persia upon those coasts, and the link between her European and Asiatic dominions, they blockaded the town and ultimately carried it. But these foreign events, however important in themselves, were trifling in comparison with a revolution which accompanied them, and which, in suddenly raising Athens to the supreme command of allied Greece, may be regarded at once as the author of the coming greatness --and the subsequent reverses--of that republic.
