4. Immediate consequences of this great revolution in respect both of the conquerors and the conquered. Among the former, even in the time of Cyrus, the civilization and luxury of the Medes, their legislation and national religion, and the sacerdotal caste of the magi, who were guardians of that religion, had been introduced, and the whole system of the Persian court had been remodelled upon that of the Medes. Description of Zoroaster's legislation, and of the magian national religion, according to the Zend-avesta. How far the dogmas of Zoroaster can be considered as dominant among the Persians?--Proof that they were adopted only by the nobler tribes, more particularly the Pasargadae. Their great and beneficial influence on agriculture. ANQUETIL DU PERRON, _Zend-avesta, ouvrage de_ ZOROASTRE, _traduit en Francois sur l'original Zend_. Paris, 1771. 4to. This work has been much improved by the critical discussions added to the German translation by J. L. KLEUKER. Compare the dissertations on Zoroaster by MEINERS and TYCHSEN, in _Comment. Soc. Gotting._ and HEEREN, _Ideas_, etc. vol. i. HYDE, _De Religione veterum Persarum_; Oxon. 1700, 4to. Replete with learned research, and the first work that excited enquiry on the subject. # J. S. RHODE, _Sacred Traditions of the East_; Breslau, 1821. An excellent work for the study of the Zend-avesta, the magian religion, and the antiquities of the Medes and Persians. 5. First political constitution of the Persian empire under Cyrus. No general new organization; but for the most part the original institutions are preserved among the conquered, who are compelled to pay tribute. Royal officers, appointed to collect the tribute, are associated with the generals, who with numerous armies keep in subjection the inhabitants of the conquered countries. For the support of the empire large standing armies are kept in pay, besides which, recourse is frequently had to the transplanting of whole nations; while, as was the case with the Jews, some who had been formerly transplanted are restored to their country. With the same view injunctions are issued, as in the case of the Lydians, to effect the enervation of warlike races by a luxurious and effeminate system of education. 6. Cyrus leaves two sons, the elder of whom, Cambyses, succeeds as king; the younger, Smerdis, (the _Tanyoxarces_ of Ctesias,) becomes independent lord of Bactria and the eastern territories; but is soon after murdered by the command of his elder brother.
