It is certainly surprising that the king formed this resolution. He was at the head of an army, returning from an expedition, which, if not wholly successful, had at any rate added to the empire an important province. His father’s name was a tower of strength; and if he could only have exposed the imposture that had been practised on them, he might have counted confidently on rallying the great mass of the Persians to his cause. How was it that he did not advance on the capital, and at least strike one blow for empire? No clear and decided response can be made to this inquiry; but we may indistinctly discern a number of causes which may have combined to produce in the monarch’s mind the feeling of despondency whereto he gave way. Although he returned from Egypt a substantial conqueror, his laurel wreath was tarnished by ill-success; his army, weakened by its losses, and dispirited by its failures, was out of heart; it had no trust in his capacity as a commander, and could not be expected to fight with enthusiasm on his behalf. There is also reason to believe that he was generally unpopular on account of his haughty and tyrannical temper, and his contempt of law and usage, where they interfered with the gratification of his desires. Though we should do wrong to accept as true all the crimes laid to his charge by the Egyptians, who detested his memory, we cannot doubt the fact of his incestuous marriage with his sister, Atossa, which was wholly repugnant to the religious feelings of his nation. Nor can we well imagine that there was no foundation at all for the stories of the escape of Croesus, the murder of the son of Prexaspes, and the execution in Egypt on a trivial charge of twelve noble Persians. His own people called Cambyses a “despot” or “master,” in contrast with Cyrus, whom they regarded as a “father,” because, as Herodotus says, he was “harsh and reckless,” whereas his father was mild and beneficent. Further, there was the religious aspect of the revolution, which had taken place, in the background. Cambyses may have known that in the ranks of his army there was much sympathy with Magism, and may have doubted whether, if the whole conspiracy were laid bare, he could count on anything like a general adhesion of his troops to the Zoroastrian cause. These various grounds, taken together, go far towards accounting for a suicide which at first sight strikes us as extraordinary, and is indeed almost unparalleled.
