ARBACES, according to Ctesias (Diodor. ii. 24 ff. 32), one of the generals of Sardanapalus, king of Assyria and founder of the Median empire about 83o B.C. But Ctesias's whole history of the Assyrian and Median empires is fabulous ; his Arbaces and his successors are not historical personages. From the in scriptions of Sargon of Assyria we know one "Arbaku Dynast of Arnashia" as one of 45 chiefs of Median districts who paid tribute to Sargon in 713 B.C. (See MEDIA.)
