3. M.Duronius, a Roman senator, who was ejected from the senate in B. C. 97 by the censors, M. Antonius, the orator, and L. Valerius Flaccus; for Duronius in his tribuneship (probably in the year B. C. 98) had abolished a lex sumptuaria, and had used very frivolous and reckless expressions on that occasion. In revenge he brought an accusation for ambitus against the censor M. Antonius. (V. Max. 2.9.5; Cic. de Orat. 2.68; comp. 64.)
