7. Under Cambyses the conquering arms of the Persians are directed against Africa. Egypt becomes a Persian province, and the neighbouring Libya, together with Cyrene, assume the yoke of their own accord. But the twofold expedition against the opulent commercial establishments, Ammonium in the west, and Meroe in the south, is wholly unsuccessful; that against Carthage is arrested in its commencement by the refusal of the Tyrians to join the naval armament. A colony of six thousand Egyptians is transplanted into Susiana. 8. The cruelty with which Cambyses is accused of treating the Egyptians was directed rather against the powerful caste of the priests, than against the whole nation; and originated more in political than in religious motives. It must be observed, however, that we ought to be particularly on our guard against all the evil that is related of Cambyses, inasmuch as our information respecting that prince is derived entirely from his enemies, the Egyptian priests. 9. The usurpation of the Pseudo-Smerdis, (or _Tanyoxarces_,) was an attempt of the magi to replace a Median dynasty on the throne, by means of a plot hatched within the seraglio. It was the occasion of an accident which cost Cambyses his life, after a reign of seven years and a half: (or, according to Ctesias, of eighteen.) 10. The Pseudo-Smerdis kept his seat on the throne eight months, during which he attempted to bring over the conquered nations to his interest by a remission of all tribute for three years; but the discovery of his cheat gave rise to a conspiracy of seven of the chief Persians, who could not brook the rule of a Mede, and the usurper lost his life. 11. It could not be expected that the political organization of the kingdom should advance to completion during the reign of Cambyses, who was almost always absent in the prosecution of war; or during the brief rule of the Pseudo-Smerdis. It remained, therefore, in the same state as under Cyrus. But the introduction of the Median court-ceremonial among the ruling tribe of the Persians, and the adoption of fixed dwellings by that tribe, rendered it necessary that royal residences should be erected for the reception of the king's court; among these Persepolis, (see above, p. 20,) probably commenced by Cyrus, was completed under Darius and Xerxes. The best drawings of the monuments of Persepolis, remarkable alike for their architecture, their sculpture, and their inscriptions in the arrow-headed character, are to be found in the Travels of CHARDIN and NIEBUHR.
