Lucius Calpurnius Piso (also known to contemporaries as Lucius Calpurnius Piso the Augur) (died AD 24) was a Roman senator who was appointed consul in 1 BC as the colleague of Cossus Cornelius Lentulus Gaetulicus.
Afterwards Calpurnius Piso was appointed the proconsular governor of Asia, possibly around AD 1.
[citation needed] In AD 16, after the treason trial and suicide of Marcus Scribonius Libo, Calpurnius Piso stated his disgust at the corruption of the judicial system.
[4] In that same year, he attempted to bring to court Urgulania, an intimate friend of the emperor's mother, Livia.
[6] An augur, Calpurnius Piso was described as having a ferocious and violent temper, and was a man who spoke his mind to Tiberius.
