Publius Cornelius Lentulus
Passienus was a regular pleader in the court of the Centumviri, which met in the Basilica Julia. Suetonius mentions a statue of Passienus, which had been set up in the Basilica. He made his first speech in the senate during the reign of Tiberius, whom he addressed politely, and whose favour he won, although Suetonius maintains that the emperor's praise was insincere. Passienus was consul for the first time in AD 27, being named "suffectus" from the Kalends of July, as the colleague of Publius Cornelius Lentulus, and serving out the remainder of the year.
