In both the dominion of the Medes has long been hated by the Persians. In both before the beginning of the struggle Astyages commands Cyrus to appear before him. In Herodotus Astyages says, when Harpagus has passed over to Cyrus and the Median army has broken up, that "he shall not succeed;" and in Nicolaus he uses the same words after the first defeat of his horsemen. In Herodotus it is the cruelty of Astyages to Harpagus, and his severity towards the Medes, which cost him his throne; in Diodorus the army revolts, even after brave fighting, from Astyages because he cruelly revenges upon them the defeat at Pasargadae. In all three accounts Cyrus does no harm to Astyages after his victory. Let us set aside the poetical colours in the account of Herodotus in order to test its coherence. What alarm could Astyages, who was without male heirs, feel at the announcement that his daughter's son would one day rule over all Asia, _i.e._ would still further extend the dominion of the Medes? In the second dream, which portends no more than the first, a reason is given for the alarm; the interpreters declare that the dream signifies that Astyages will lose his throne. If Astyages had reason to fear the yet unborn child of his daughter, the obvious remedy was not to allow her to marry. Nevertheless she is married, not to a Mede, but to a man of the subject races, a Persian of a good family, _i.e._ of noble descent, wealthy, but "quiet in his disposition." This was equivalent to taking the Persian into the royal family, giving up to him or his son the right of succession, bringing the crown of Media into the possession of a stranger, and allowing the kingdom to pass from the Medes to the Persians. Even if such perversity could occur to Astyages the Medes were not likely to permit it, when the Magians tell Astyages, in Herodotus, how anxious they are that the dominion should not fall into the hands of a Persian. It is true that Herodotus represents Harpagus some twenty or thirty years later as persuading the chief Medes, and persuading them singly, that Astyages must be overthrown, and the Persian made king, but this is simply incredible. After this marvellous marriage of the heiress to the throne with a Persian, Cambyses is not brought to Ecbatana to the court, but remains in Persia, and no harm is done to the dreaded son of the marriage, even when his real origin has been discovered. Nay, more, the boy who at an early age discovers high aims, and a resolute will, is not even brought to the court to be under the eye of Astyages, but is sent back to Persia to his father, and by his means Harpagus is able to bring Persia to revolt. The letter hidden in the hare's belly obviously arose from an anticipation of the supervision of the great roads which was introduced at a later time by the Achæmenids. But what reason had Cyrus to cause the Persians to revolt? According to Herodotus Cambyses is the son-in-law, and hence the heir, of Astyages.
