Oebares
Oebares was a Persian officer of Cyrus (c. 5th century BC ). When Cyrus sent Petisaces to bring Astyages to court from his satrapy, Oebares caused Petisaces to leave the old king Astyages to die in the desert, when this was discovered he proceeded to starve himself to death to avoid falling to an act of vengeance from Astyages' daughter.
