He was, according to Herodotus, twenty years old at the death of Cyrus. Herod. 1, 209; 3, 139. Ctesias ("Pers." 19) gives Darius a reign of thirty-one years and a life of seventy-two. That the reign of Darius lasted thirty-six years is fixed both by the astronomical canon and Egyptian inscriptions, which mention the thirty-sixth year of Darius; and lastly by the Egibi-tablets of Babylon, which give dates out of thirty-five years (with the single exception of the seventh year). "Transact. Bibl. Arch." 6, 69 ff. According to Ctesias, Darius would be thirty-six years old in the year 521 B.C.
