Histories

Darius took wives from the noblest houses of Iran [53,32] (nation), AsiaPersia, marrying Cyrus' daughters Atossa and Artystone; Atossa had been a wife of her brother Cambyses and afterwards of the Magus; Artystone was a virgin.

He also married a daughter of Cyrus' son Smerdis, whose name was Parmys, and the daughter of Otanes who had discovered the truth about the Magus; and everything was full of his power. First he made and set up a carved stone, upon which was cut the figure of a horseman, with this inscription: “Darius son of Hystaspes, aided by the excellence of his horse” (here followed the horse's name) “and of Oebares his groom, got possession of the kingdom of Iran [53,32] (nation), AsiaPersia.”
