(Μιτροβάτης), a Persian, governor of Dascyleium, is said by Herodotus to have taunted Oroetes, satrap of Sardis, with his allowing Samos to continue free from the Persian yoke. During the disturbed period which followed the death of Cambyses and the usurpation of the Magi (B. C. 521), Oroetes put Mitrobates and his son Cranaspes to death. (Hdt. 3.120, 126, 127.)
