Po'llio, Cae'lius
was commander of the Roman army in Armenia, A. D. 51, and was bribed by Rhadamistus to betray the cause of Mithridates king of Armenia, whom the Romans had placed upon the throne. Notwithstanding his corrupt conduct, he was allowed to remain in Armenia till the first year of Nero's reign, A. D. 54, when he was succeeded by Laelianus. (
