A Dictionary of Greek and Roman biography and mythology

2. The daughter of Servilia and D. Junius Silanus, consul in B. C. 62. She was also the halfsister of M. Junius Brutus, the murderer of Caesar, who was the son of Servilia by her first husband, M. Junius Brutus, tribune of the plebs in B. C. 83. Junia was married to M. Lepidus, subsequently the triumvir. When Cicero was in Cilicia, in B. C. 50, he was told that she was not faithful to Lepidus: he speaks of her portrait being found among the chattels of the debauchee P. Vedius, and expresses his surprise at her brother and husband taking no notice of her conduct. He afterwards speaks of her in one of the Philippics in terms of praise (probatissima uxor). She seems, at all events, to have won the affections of her husband; and when she became involved in the conspiracy formed by her son Lepidus against the life of Octavian, after the battle of Actium, her husband offered to become security for her. (Cic. Att. 6.1, 14.8, Phil. 13.4; Vell. 2.88; Appian, App. BC 4.50.)
