This prediction turned out to be true. A prodigy appeared, by which the Samians were greatly frightened. An eagle carried off the public ring (some seal apparently which was affixed to the proceedings of the Town Council), and let it drop into the bosom of a slave. The philosopher was consulted on the matter, both in his capacity as a philosopher and as being one of the Republic. He asked for time, and had recourse to his usual oracle, Æsop. The latter advised him to produce him in public, since, if he succeeded well, the philosopher would have the honour, and if he failed, he, Æsop, would alone bear the blame. Xantus approved of this course, and presented him before the chief assembly of the citizens. As soon as the Phrygian appeared, every one burst into a fit of laughter; no one supposed that anything sensible could come from the mouth of one so grotesquely formed. Æsop told them, however, that they should not consider the fashion of the vase, but the liquor which it contained; whereupon the Samians cried out to him to say without fear what he thought of the prodigy. But Æsop excused himself on the ground that he dare not. "Fortune," he said, "had raised a strife for glory between the master and the slave. If the slave spoke badly, he would be beaten; and if he spoke better than his master, he would still be beaten." Upon this every one pressed Xantus to set the Phrygian free. The philosopher obstinately resisted for some time; but at length the provost of the town threatened to do so himself, in virtue of his magisterial power. This had the desired effect, and Æsop was set free, upon which he declared the Samians were threatened by this prodigy with being reduced to a state of servitude, and that the carrying off of their ring by the eagle was symbolic of a powerful monarch who was desirous of subjugating them.
Shortly afterwards Crœsus, King of the Lydians, announced to the Samians that if they did not become his tributaries, he would compel them to do so by force of arms. The greater number were for obeying his commands. Æsop told them that Fortune offered to men the choice of two roads: the one, that of liberty, rough and thorny at the commencement, but afterwards very pleasant; and the other that of slavery, which at first was easy, but was afterwards very laborious. This was, in effect, plain advice to the Phrygians to defend their liberties; so they dismissed the monarch's envoy, unsatisfied as to his demands.
