The reader will recollect that, as was related in the last chapter, Cambyses first sent his brother Smerdis home, and afterward, when alarmed by his dream, he sent Prexaspes to murder him. Now the return of Smerdis was publicly and generally known, while his assassination by Prexaspes was kept a profound secret. Even the Persians connected with Cambyses's court in Egypt had not heard of the perpetration of this crime, until Cambyses confessed it on his dying bed, and even then, as was stated in the last chapter, they did not believe it. It is not probable that it was known in Media and Persia; so that, after Prexaspes accomplished his work, and returned to Cambyses with the report of it, it was probably generally supposed that his brother was still alive, and was residing somewhere in one or another of the royal palaces. Such royal personages were often accustomed to live thus, in a state of great seclusion, spending their time in effeminate pleasures within the walls of their palaces, parks, and gardens. When the royal Smerdis, therefore, secretly and suddenly disappeared, it would be very easy for the magian Smerdis, with the collusion of a moderate number of courtiers and attendants, to take his place, especially if he continued to live in retirement, and exhibited himself as little as possible to public view. Thus it was that Cambyses himself, by the very crimes which he committed to shield himself from all danger of a revolt, opened the way which specially invited it, and almost insured its success. Every particular step that he took, too, helped to promote the end. His sending Smerdis home; his waiting an interval, and then sending Prexaspes to destroy him; his ordering his assassination to be secret--these, and all the other attendant circumstances, were only so many preliminary steps, preparing the way for the success of the revolution which was to accomplish his ruin. He was, in a word, his own destroyer. Like other wicked men, he found, in the end, that the schemes of wickedness which he had malignantly aimed at the destruction of others, had been all the time slowly and surely working out his own.
