Lucius Calpurnius Piso Caesoninus (48 BC – AD 32) was a prominent Roman senator of the early Empire.
He was the son of Lucius Calpurnius Piso Caesoninus, consul in 58 BC, and half-brother of Calpurnia, the third and last wife of Julius Caesar.
[6] Secondly, Theodor Mommsen identified his sons, to whom the Ars Poëtica is addressed, with Lucius Calpurnius Piso and Marcus Licinius Crassus Frugi, consuls in AD 27.
[8][9][6] However, Klebs doubted this interpretation of Fourtios, and it is not at all certain that the consuls of AD 27 were the sons of Lucius Calpurnius Piso Pontifex.
[10][11] In this instance, Marcus Licinius Crassus Frugi would be identified with the Gnaeus Calpurnius Piso whom the senate compelled to change his praenomen.
