Claim: Cyrus I, who reigned over Anshan in Persia, could have been born no later than 675 BC if he is indeed Arukku's father.
Evidence: Cyrus I (Old Persian: Kuruš) or Cyrus I of Anshan or Cyrus I of Persia, was King of Anshan in Persia from c. 600 to 580 BC or, according to others, from c. 652 to 600 BC. Traditionally Arukku is usually identified as the son of Cyrus I. According to this chronology, in which Cyrus already occurs as a father and king, the birth of Cyrus would be no later than 680 to 675 BC.
