The king then gave them presents and dismissed them to their homes. He also sent Onesikritos to the most renowned of these sages, who lived by themselves in tranquil seclusion, to request that they would come to him.[395] This Onesikritos was a philosopher who belonged to the school of Diogenês the Cynic. He tells us that one of these men called Kalanos ordered him with the most overbearing insolence and rudeness to take off his clothes, and listen naked to his discourse—otherwise he would not enter into conversation with him even if he came from Zeus himself. Dandamis, however, was of a milder temper, and when he had been told about Sôkrates, Pythagoras and Diogenês, he said they appeared to him to have been men of genius, but from an excessive deference to the laws had subjected their lives too much to their requirements. But other writers tell us that he said nothing more than this, “For what purpose has Alexander come all the way hither?” Taxilês, however, persuaded Kalanos to visit Alexander. His real name was Sphinês, but as he saluted those whom he met with “Kale,” which is the Indian equivalent of “Chairein” (that is, “All hail”), he was called by the Greeks Kalanos. This philosopher, we are told, showed Alexander a symbol of his empire. He threw down on the ground a dry and shrivelled hide and planted his foot on the edge of it. But when it was trodden down in one place, it started up everywhere else. He then walked all round it and showed that the same thing took place wherever he trod, until at length he stepped into the middle, and by doing so made it all lie flat. This symbol was intended to show Alexander that he should control his empire from its centre, and not wander away to its distant extremities. _Chapter LXVI.—Alexander visits the island Skilloustis, and sailing thence explores the sea—Sufferings of his army on the march homeward, and extent of its losses—Relief sent by the satraps_ [Illustration: FIG. 13.—GREEK WARSHIP.]
