Josephus, in his "Antiquities of the Jews", describes a place called Saba as a walled, royal city of Ethiopia that Cambyses II renamed as Meroë. He writes that "it was both encompassed by the Nile quite round, and the other rivers, Astapus and Astaboras", offering protection from both foreign armies and river floods. According to Josephus it was the conquering of Saba that brought great fame to a young Egyptian prince, simultaneously exposing his personal background as a slave child named Moses.
