The murder of Smerdis cannot have remained an entire secret. The murderer or murderers knew it, and the relatives, the members of the house of Achæmenes, the servants and women, cannot have been deceived by the resemblance for any length of time. The narrative of Darius tells us plainly, "that Gaumata put to death many men in order that it might not be known that he was not the son of Cyrus." There is no doubt that Cambyses, when dying, acknowledged his deed, but only to the Achæmenids and the six tribal princes. Darius was with Cambyses in Egypt. From Herodotus we learn that he secretly sent messages to the satraps at the time of the rule of the Magians[208]. Hence he knew of the fact, and, as was fitting, he urged the overthrow of the Magian before all others. Why the younger line of the royal house and the tribal princes of the Persians did not come forward immediately after the death of Cambyses--why they did not call on the Persians to rise against the Magians--on these matters we can only make conjectures, which however are of a suggestive kind. One obvious reason was that the declaration that the throne had been usurped, and the rising of the Persians which would have followed such a declaration, would have thrown the kingdom into the most violent convulsions. This would have given the subject nations the choice of taking up arms for their favourite, the usurper, or for their own independence; it would have given them the right, and the Medes above all, of throwing off the existing rule. Could they venture to renew the dangerous war, which Cyrus had waged against the Medes, which had been so long undecided, and had brought the Persians into the greatest distress, in which they had conquered only after the most severe efforts? Who would guarantee a happy issue to the new conflict? And if the Medes were really conquered for the second time, would not the conflict with them be the signal for the other nations to revolt on their part also? In this way the kingdom of Cyrus would be completely disorganized. Thus Hystaspes and Darius and the princes of the Persians hesitated; and contented themselves with coming to a secret understanding with the satraps. So long as the royal house and the six princes remained silent, the pretended son of Cyrus was compelled to spare the Achæmenids and the tribal princes in order to play his own part, but their silence on the other hand declared the Magian to be the legitimate ruler, and the longer that they were silent the more securely did they establish his throne. This position of affairs was the more difficult for the Achæmenids, because Gaumata, as we are told in the inscription, removed his residence from Persia to Media. He was aware no doubt that his deception could not be long maintained against the Persians and the satraps. In Media, therefore, he was more secure than in Persia, for in Media the Magians formed a numerous and exclusive order.
