This Aryandes had been appointed viceroy of Egypt by Cambyses; at a later day, he was put to death for making himself equal to Darius. For, learning and seeing that Darius desired to leave a memorial of himself such as no king ever had, Aryandes imitated him, until he got his reward; for Darius had coined money out of gold refined to an extreme purity, and Aryandes, then ruling Egypt, made a similar silver coinage; and now there is no silver money so pure as is the Aryandic. But when Darius heard that Aryandes was doing so, he put him to death, not on this charge but as a rebel.
