[The first rebellion in Egypt, which broke out under Aryandes, the satrap appointed by Cambyses, was put down by Darius in person. He visited Egypt, and promised 100 talents (L22,500.) to any one who would find a new Apis. Polyaen. VII. ii. 7. No second outbreak took place until 486 B.C. about 4 years before the death of Darius. Herod. VI i. Xerxes conquered the rebels two years after his accession, and appointed his brother Achaemenes satrap of Egypt.] It was reserved for Xerxes, the successor and son of Darius and Atossa, to bring back the inhabitants of the Nile valley to a forced and therefore insecure obedience.
Darius left a worthy monument of his greatness in the glorious palace which he built on Mount Rachmed, the ruins of which are the wonder and admiration of travellers to this day. Six thousand Egyptian workmen, who had been sent to Asia by Cambyses, took part in the work and also assisted in building a tomb for Darius and his successors, the rocky and almost inaccessible chambers of which have defied the ravages of time, and are now the resort of innumerable wild pigeons.
He caused the history of his deeds to be cut, (in the cuneiform character and in the Persian, Median and Assyrian languages), on the polished side of the rock of Bisitun or Behistan, not far from the spot where he saved Atossa's life. The Persian part of this inscription can still be deciphered with certainty, and contains an account of the events related in the last few chapters, very nearly agreeing with our own and that of Herodotus. The following sentences occur amongst others: "Thus saith Darius the King: That which I have done, was done by the grace of Auramazda in every way. I fought nineteen battles after the rebellion of the kings. By the mercy of Auramazda I conquered them. I took nine kings captive. One was a Median, Gaumata by name. He lied and said: 'I am Bardiya (Bartja), the son of Cyrus.' He caused Persia to rebel."
Some distance lower down, he names the chiefs who helped him to dethrone the Magi, and in another place the inscription has these words: "Thus saith the King Darius: That which I have done was done in every way by the grace of Auramazda. Auramazda helped me, and such other gods as there be. Auramazda and the other gods gave me help, because I was not swift to anger, nor a liar, nor a violent ruler, neither I nor my kinsmen. I have shown favor unto him who helped my brethren, and I have punished severely him who was my enemy. Thou who shalt be king after me, be not merciful unto him who is a liar or a rebel, but punish him with a severe punishment. Thus saith Darius the King: Thou who shalt hereafter behold this tablet which I have written, or these pictures, destroy them not, but so long as thou shalt live preserve them, &c."
