FIMBRIA, GAIUS FLAVIUS (d. 84 B.c.), Roman soldier, partisan of Marius. He was sent to Asia in 86 B.C. as legate to L. Valerius Flaccus, but quarrelled with him and was dismissed. Taking advantage of the absence of Flaccus at Chalcedon Frimbia revolted and slew Flaccus at Nicomedia. He then took command of the army and obtained several successes against Mithridates, whom he shut up in Pitane on the coast of Aeolis, and would undoubtedly have captured him had Lucullus co operated with the fleet. Fimbria treated most cruelly all people of Asia who had revolted against Rome or sided with Sulla. Having gained admission to Ilium by declaring that, as a Roman, he was friendly, he massacred the inhabitants and burnt the place to the ground. But in 84 Sulla crossed over from Greece to Asia, made peace with Mithridates, and turned his arms against Fimbria, who committed suicide. His troops were made to serve in Asia till the end of the third Mithridatic War.
