But the Egyptians, who say that Cambyses was the son of this daughter of Apries, claim him as one of theirs; they say that it was Cyrus who asked Amasis for his daughter, and not Cambyses. But what they say is false. They are certainly not unaware (for if any understand the customs of the Persians the Egyptians do) firstly, that it is not their custom for illegitimate offspring to rule when there are legitimate offspring; and secondly, that Cambyses was the son of Cassandane, the daughter of Pharnaspes, who was an Achaemenid, and not of the Egyptian woman. But they falsify the story, pretending to be related to the house of Cyrus. That is the truth of the matter.
