Appius Junius Silanus (died AD 43), whom Cassius Dio calls Gaius Appius Silanus, was consul in AD 28, with Publius Silius Nerva as his colleague.
[1] He was accused of majestas, or treason, in AD 32 along with a number of senators, but he and Gaius Calvisius Sabinus were saved by one of the informers, Celsus, a tribune of a city cohort.
[2][3] Shortly after the accession of Claudius, in AD 41, when Silanus was governor of Hispania Tarraconensis, he was recalled to Rome and married to Domitia Lepida Minor, mother of the empress Messalina.
He was treated with the greatest of distinction, but having refused the advances of Messalina herself, he was soon put to death by the emperor.
He is sometimes confused with Marcus Junius Silanus Torquatus, consul in AD 19.
