This result is not rendered doubtful by the fact that Xenophon calls this Median king Κυαξάρης and describes him as the son of Astyages, while, on the contrary, Daniel calls him Darjawesch (Darius) the son of Ahasuerus (Dan 9:1). The name Κυαξάρης is the Median Uwakshatra, and means autocrat; ̓Αστυάγης corresponds to the Median Ajisdahâka, the name of the Median dynasty, meaning the biting serpent (cf. Nieb. Gesch. Assurs, p. 175f.). דּריושׁ, Δαρεῖος, the Persian Dârjawusch, rightly explained by Herod. vi. 98 by the word ἐρξείης, means the keeper, ruler; and אחשׁורושׁ, Ahasverus, as the name of Xerxes, in the Persian cuneiform inscriptions Kschajârschâ, is certainly formed, however one may interpret the name, from Kschaja, kingdom, the title of the Persian rulers, like the Median “Astyages.” The names Cyaxares and Darjawesch are thus related to each other, and are the paternal names of both dynasties, or the titles of the rulers. Xenophon has communicated to us the Median name and title of the last king; Daniel gives, as it appears, the Persian name and title which Cyaxares, as king of the united Chaldean and Medo-Persian kingdom, received and bore.
