The debate at Camarina, though interesting and instructive from the light which it throws on the passions and motives of the combatants, had little influence on the final issue of the war. But about the same time a scene was being enacted in another part of the Greek world, which led to most momentous consequences. Early in the winter the Syracusan envoys arrived at Corinth, and made an earnest appeal for help. The Corinthians were warmly attached to their famous colony, which had never wavered in its allegiance to the mother-city, and moreover they were the implacable enemies of Athens. They therefore took up the cause of Syracuse with enthusiasm, and they sent the envoys on to Sparta, accompanied by delegates of their own, to urge the immediate resumption of hostilities against Athens, and the sending of prompt aid to Sicily. At Sparta they found an able and unscrupulous ally, the very last whom they had expected to meet there. This was the outlaw Alcibiades, who, after eluding the vigilance of the Athenian officers at Thurii, had crossed over in a merchant ship to Cyllene, the port of Elis. While staying there, he received an invitation from the Lacedaemonians to proceed to Sparta, and made his way thither, having first stipulated for a safe-conduct; for he dreaded the vengeance of the Spartans, to whom he had done much mischief by raising the coalition which led to the battle of Mantinea. So there he was, the guest of his old enemies, burning with all an exile's hatred, and ready to strike some deadly blow against the city which had cast him out. At first the Spartans gave but a cool and qualified response to the application of the envoys from Corinth. They were prepared to lend moral support to the Syracusans, by sending an embassy to encourage them in their resistance, but of more substantial aid they said little or nothing. Now was the time for Alcibiades to play his part. He knew, far better than any of his hearers, all the vulnerable points of Athens, and had no scruple in using his knowledge for her ruin. Having obtained permission from the magistrates, he rose to address the Spartan assembly; and his speech is given at full length by the historian, who was himself an exile at the time, and may possibly have been present [Footnote: The suggestion is made by Grote.] on this important occasion.
