Note 6 — THE PERSIANS[2]
E. H. (Edward Hayes) Plumptre translation
Here, as in Herodotos and Greek writers generally, the title, “the King,” or “the great King,” was enough. It could be understood only of the Persian. The latter name had been borne by the kings of Assyria (2 Kings xviii. 28). A little later it passed into the fuller, more boastful form of “The King of kings.”
