Note 558 — Chapter IV

According to the canon of Ptolemy, Cyrus dies 529 B.C. We arrive at the same year if we reckon back from the death of Darius. This took place five years after the battle of Marathon (Herod. 7, 1-4), i. e. 485 B.C. Darius reigned 36 years according to Herodotus and the canon of Ptolemy. An Egyptian pillar gives the year 34, a demotic contract the year 35 of his reign: he ascended the throne therefore in 521 B.C. Before him the Magian reigned for seven months, Cambyses for seven years and five months (Herod. 3, 66, 67). The canon of Ptolemy omits the Magian and gives Cambyses eight years, because it reckons by complete years; hence Cambyses ascended the throne in 529. As Cyrus, according to Herodotus, reigned 29 years after his accession (1, 214), the beginning of his reign over Media must be placed in 558. If Ctesias gives Cyrus a reign of 30 years ("Pers." 8), like Deinon (p. 369), and Justin (1, 8), and Eusebius a reign of 31 years, these statements may be reconciled by the fact that Cyrus may have taken up arms against Media 30 or 31 years before his death, and reigned 29 years after the overthrow of Astyages. Diodorus puts the beginning of Cyrus: Olymp. 55, 1 = 560 B.C. Africanus in Euseb. "Præp. Evang." 10, p. 488.
