2. Son and successor of the above. Already, however, before his father's death, he had received from the Roman senate the title of king, to which some grant of territory was apparently attached. With this Deiotarus, Cicero tells us that his son and his nephew remained, while himself and his brother Quintus were occupied with their campaign in Cilicia, B. C. 51. (Cic. Att. 5.17, 18,Phil. 11.12.) In the war between Antony and Octavius he took part with the former, but went over from him to the enemy in the battle of Actium, B. C. 31. He was succeeded in his kingdom by AMYNTAS, No. 6. Cicero speaks of him, as well as of his father, in very high terms. (Plut. Ant.61, 63 ; comp. D. C. 1. 13, 51.2; Strab. xii. p.567; Cic. Phil. 11.13.)
