These also are like the images of Hephaestus, and are said to be his sons. I hold it then in every way proved that Cambyses was quite insane; or he would never have set himself to deride religion and custom. For if it were proposed to all nations to choose which seemed best of all customs, each, after examination, would place its own first; so well is each convinced that its own are by far the best. It is not therefore to be supposed that anyone, except a madman, would turn such things to ridicule. I will give this one proof among many from which it may be inferred that all men hold this belief about their customs. When Darius was king, he summoned the Greeks who were with him and asked them for what price they would eat their fathers' dead bodies. They answered that there was no price for which they would do it.
The quote: Then Darius summoned those Indians who are called Callatiae, who eat their parents, and asked them (the Greeks being present and understanding through interpreters what was said) what would make them willing to burn their fathers at death. The Indians cried aloud, that he should not speak of so horrid an act. So firmly rooted are these beliefs; and it is, I think, rightly said in Pindar's poem that custom is lord of all.
While Cambyses was attacking Egypt , the Lacedaemonians too were making war upon Samos and upon Aeaces' son Polycrates, who had revolted and won Samos . And first, dividing the city into three parts, he gave a share in the government to his brothers Pantagnotus and Syloson; but presently he put one of them to death, banished the younger, Syloson, and so made himself lord of all Samos ; then he made a treaty with Amasis king of Egypt , sending to him and receiving from him gifts.
