(), a Persian who joined in the general revolt
of the western provinces from Artaxerxes Mnemon, in B. C. 362, and
was employed by his confederates to go to Tachos, king of Egypt, for aid. Having returned to
Asia, with 500 talents and 50 ships of war, he sent for a number of the rebel chiefs to
receive the subsidy, and, on their arrival, he arrested them, and despatched them in chains to
Artaxerxes, thus making his own peace at court. It was perhaps the same Rheomithres, whom we
find in command of a body of 2000 cavalry, for Dareius III., at the battle of the Granicus, in
B. C. 334, and who fell in the next year at the battle of Issus.
