and in the three last years of his Reign subdued Egypt: he was succeeded by Mardus, or Smerdis the Magus, who feigned himself to be Smerdis the brother of Cambyses.
Smerdis Reigned seven months, and in the eighth month being discovered, was slain, with a great number of the Magi; so the Persians called their Priests, and in memory of this kept an anniversary day, which they called, *The slaughter of the Magi_. Then Reigned *Maraphus_ and Artaphernes a few days, and after them Darius the son of Hystaspes, the son of Arsamenes, of the family of Achæmenes, a Persian, being chosen King by the neighing of his horse: before he Reigned his [479] name was Ochus. He seems on this occasion to have reformed the constitution of the Magi, making his father Hystaspes their Master, or Archimagus; for Porphyrius tells us, [480] that *the Magi_ were a sort of men so venerable amongst the Persians, that Darius the son of Hystaspes wrote on the monument of his father, amongst other things, that he had been the Master of the Magi. In this reformation of the *Magi_, Hystaspes was assisted by Zoroastres: so Agathias; *The Persians_ at this day say simply that Zoroastres lived under Hystaspes: and Apuleius; *Pythagoram, aiunt, inter captivos Cambysæ Regis *[ex Ægypto Babylonem abductos] doctores habuisse Persarum Magos, & præcipue Zoroastrem, omnis divini arcani Antistitem. By Zoroastres_'s conversing at Babylon he seems to have borrowed his skill from the Chaldæans; for he was skilled in Astronomy, and used their year: so Q. Curtius; [481] _Magi proximi patrium carmen canebant: Magos trecenti & sexaginta quinque juvenes sequebantur, puniceis amiculis velati, diebus totius anni pares numero: and Ammianus; Scientiæ multa ex Chaldæorum arcanis Bactrianus addidit Zoroastres_. From his conversing in several places he is reckoned a Chaldæan, an Assyrian, a Mede, a Persian, a Bactrian. Suidas calls him [482] a Perso-Mede, and saith that he was _the most skilful of Astronomers, and first author of the name of the Magi received among them. This skill in Astronomy he had doubtless from the Chaldæans_, but Hystaspes travelled into India, to be instructed by the Gymnosophists: and these two conjoyning their skill and authority, instituted a new set of Priests or Magi, and instructed them in such ceremonies and mysteries of Religion and Philosophy as they thought fit to establish for the Religion and Philosophy of that Empire; and these instructed others, 'till from a small number they grew to a great multitude: for Suidas tells us, that _Zoroastres gave a beginning to the name of the Magi: and Elmacinus; that he reformed the religion of the Persians, which before was divided into many sects: and *Agathias_; that *he introduced the religion of the Magi among the *Persians_, changing their ancient sacred rites, and bringing in several opinions_: and Ammianus [483] tells us, Magiam esse divinorum incorruptissimum cultum, cujus scientiæ seculis priscis multa ex Chaldæorum arcanis Bactrianus addidit Zoroastres: deinde Hystaspes Rex prudentissimus Darii pater; qui quum superioris Indiæ secreta fidentius penetraret, ad nemorosam quamdam venerat solitudinem, cujus tranquillis silentiis præcelsa Brachmanorum ingenia potiuntur; eorumque monitu rationes mundani motus & siderum, purosque sacrorum ritus quantum colligere potuit eruditus, ex his quæ didicit, aliqua sensibus Magorum infudit; quæ illi cum disciplinis præsentiendi futura, per suam quisque progeniem, posteris ætatibus tradunt. Ex eo per sæcula multa ad præsens, una eademque prosapia multitudo creata, Deorum cultibus dedicatur. Feruntque, si justum est credi, etiam ignem coelitus lapsum apud se sempiternis foculis custodiri, cujus portionem exiguam ut faustam præisse quondam Asiaticis Regibus dicunt: Hujus originis apud veteres numerus erat exilis, ejusque mysteriis Persicæ potestates in faciendis rebus divinis solemniter utebantur. Eratque piaculum aras adire, vel hostiam contrectare, antequam Magus conceptis precationibus libamenta diffunderet præcursoria. Verum aucti paullatim, in amplitudinem gentis solidæ concesserunt & nomen: villasque inhabitantes nulla murorum firmitudine communitas & legibus suis uti permissi, religionis respectu sunt honorati. So this Empire was at first composed of many nations, each of which had hitherto its own religion: but now Hystaspes and Zoroastres collected what they conceived to be best, established it by law, and taught it to others, and those to others, 'till their disciples became numerous enough for the Priesthood of the whole Empire; and instead of those various old religions, they set up their own institutions in the whole Empire, much after the manner that Numa contrived and instituted the religion of the Romans: and this religion of the Persian Empire was composed partly of the institutions of the Chaldæans, in which Zoroastres was well skilled; and partly of the institutions of the ancient Brachmans, who are supposed to derive even their name from the Abrahamans, or sons of Abraham, born of his second wife Keturah, instructed by their father in the worship of ONE GOD without images, and sent into the east, where Hystaspes was instructed by their successors. About the same time with Hystapes and Zoroastres, lived also Ostanes, another eminent Magus: Pliny places him under Darius Hystaspis, and Suidas makes him the follower of Zoroastres: he came into Greece with Xerxes, and seems to be the Otanes of Herodotus, who discovered Smerdis, and formed the conspiracy against him, and for that service was honoured by the conspirators, and exempt from subjection to Darius.
