(Ὀρτιάγων), one of the three princes of Galatia, when that country was invaded by the Romans under Cn. Manlius Vulso, in B. C. 189. he was defeated on Mount Olympus by the invaders, and compelled to fly home for refuge. Polybius tells us that he cherished the design of uniting all Galatia under his rule, and that he was well qualified to succeed in the attempt, being liberal, magnanimous, possessed of sagacity and winning manners; and above all, brave and skilful in war. (Plb. 22.21; Liv. 38.19, &c.) [CHIOMARA]
