Cyrus will succeed his father as heir to the Median throne, why then should he rebel against his aged grandfather?--why should he seek by hazard, danger, and bloodshed, a crown which by inheritance must soon come to Cambyses or Cyrus?[544] In the narrative of Herodotus Cyrus is no more than an instrument in the hands of Harpagus. The crime of Astyages against Harpagus; the well-merited punishment of this crime by his own imprisonment and loss of empire, form the hinge of the narrative, which at the same time brings into prominence the doctrine that no one, even though warned, can escape his doom. It is not probable that there were songs among the Persians or Medes, which illustrated Herodotus' view of the unavoidable _Nemesis_ which governs the actions and fortunes of men; or that Persian poems would represent Cyrus as the son of a Median mother. In them the Persians merely glorified the founder of their freedom and supremacy, of whom, as we know, they cherished the most grateful memories. But the Medes might possess poems in which the change of empire was treated from their point of view; they might attempt to make the loss of empire appear less painful, the dishonour of defeat by the Persians less degrading. To be overthrown by a man belonging to the subject race was bitter. Hence the Medes could avail themselves of a change frequent in the East, and represent Cyrus as a scion of their own royal house. The Egyptians maintained that Cambyses, the son of Cyrus, who reduced them to subjection, was the son of Cyrus and the daughter of their own Pharaoh Hophra.[545] This was mere invention; and the Medes must have found their version the more easy to maintain, because Cyrus spared Astyages after the defeat, and took his daughter into his harem. And if it was not the arms of the Persians, but rather the treachery of a distinguished Mede, the discontent of the chiefs of Media with a cruel king, that decided the struggle between the Persians and Medes, the submission became thus less intolerable to the pride of the Medes. If a distinguished Mede had been at variance with Astyages, and in the last moment of the battle had gone over to Cyrus,--much could be made of the desertion in Median poems. If after his victory Cyrus reposed great confidence in an eminent Mede, this might be made a ground for previous treachery to Astyages. A few years after his victory Cyrus entrusted to the Mede Harpagus, the leadership of the army, the subjugation and maintenance of far distant regions. If the legend of the Persians represented Achæmenes, the ancestor of their princely race, as being fed by an eagle (p. 327), their poems would speak of the founder of their dominion as distinguished by divine honours, and surround his birth and youth with happy omens of the future. These traits the Medes could use for their own purposes as warnings vouchsafed to Astyages. If the Persians represented Cyrus as suckled by a dog, the favoured
