Cyrus was raised as Mitridates' own son, and Harpagus presented the stillborn child to Astyages as the dead Cyrus. When Cyrus was found alive at age ten, Astyages spared the boy on the advice of his Magi, returning him to his parents in Anshan. Harpagus, however, did not escape punishment, as Astyages is said to have fed him his own son at a banquet. Cyrus succeeded his father in 559, and in 553, on the advice of Harpagus, who was eager for revenge for being given the "abominable supper," Cyrus rebelled against Astyages. After three years of fighting, Astyages' troops mutinied during the battle of Pasargadae, and Cyrus conquered the Median's empire. Astyages was spared by Cyrus, and despite being taunted by Harpagus, Herodotus says he was treated well and remained in Cyrus' court until his death. Rather than giving the popular mythology that Cyrus was suckled by a dog (the dog was sacred to Persians. cf. also the legend of Sargon, or the similar legend of Romulus and Remus, suckled by a she-wolf ()) Herodotus explains that the herdsman Mitridates lived with another of Astyages' slaves, a woman named 'Spaco,' which he explains is Median for "dog," which gives both the legend and Herodotus' rationalized version.
