4. Of Beroea, an officer in the army of Perseus, with which he opposed the Roman consul P. Licinius Crassus B. C. 171. (Liv. 42.58.) He is again mentioned as holding an important command under Perseus just before the battle of Pydna, B. C. 166. After that action he fled, with his two colleagues, Hippias and Pantauchus, to Beroea, where they were the first to set the example of defection, by surrendering that fortress into the hands of Aemilius Paullus. (Liv. 44.32, 45 Plut. Aemnil. 16.)
