Луций Валерий Флакк
Marcus Duronius was a tribune of the "plebs", most likely in 97 BC. He abrogated a sumptuary law, one of the "Leges Liciniae". In retaliation, the Roman censors Lucius Valerius Flaccus and Marcus Antonius expelled him from the Senate. Duronius then brought an accusation of "ambitus" against Antonius.
