(*Gada/tas], an Assyrian satrap, revolted to Cyrus, according to Xenophon in the Cyropaedeia, to revenge himself on the king of Assyria, who had had him made an eunuch because, being a handsome man, one of the royal concubines had cast on him an eye of favour. Having found means to betray to Cyrus an important fortress, his province was invaded by the Assyrian king; but Cyrus hastened to his relief, and saved him and his forces at a very critical moment. After this Gadatas, through fear of the Assyrians, left his satrapy and joined the army of Cyrus, to whom he proved of great sse, through his knowledge of the country. On the capture of Babylon, the king was slain by Gadatas and GOBRYAS. (Xen. Cyrop 5.2.28, 3. §§ 8-29, 4. §§ 1-14, 29-40, 7.5. §§ 24-32.)
