Gnaeus Calpurnius Piso (Latin: Cn. Calpurnius Cn. f. Cn. n. Piso,[1] ca. 44 BC/43 BC - AD 20), was a Roman statesman during the reigns of Augustus and Tiberius. He was consul in 7 BC;[2] subsequently, he was governor of Hispania and proconsul of Africa. He belonged to one of Rome's most distinguished Senatorial families, whose members included Calpurnia, third wife of Julius Caesar.

Family[edit]

He was a member of the gens Calpurnia, specifically among the Calpurnii Pisones. His father and grandfather both shared his name, with his father being Gnaeus Calpurnius Piso (consul in 23 BC), and his grandfater being one of the participants in the Catiline Conspiracy. He had a brother, Lucius Calpurnius Piso, who was an augur and became consul in 1 BC.[1][3]

Piso had two sons, Lucius Calpurnius Piso (born Gnaeus), and Marcus Calpurnius Piso.

Career[edit]

Piso held many positions under Augustus and Tiberius. He was in charge of the imperial mint and in 7 BC he was made consul with Tiberius, and was sent by Augustus as legate to Hispania.[1][4]

In 3 BC he was proconsul of the province Africa, and of Hispania Tarraconensis in AD 9.[5][4] According to Tacitus, he was cruel to the people of Spain, but during his trial in AD 20 such claims were discounted as "old and irrelevant".[6]

Though he was given may appointments throughout his career, he was known to have a temper. In AD 16, he argued against Tiberius that the senate should be able to conduct business without the emperor if the emperor was away from Rome. It was only after a lengthy debate between Piso and senators close to Tiberius that he lost the debate.[5]

Governorship of Syria[edit]

In AD 17, heir designate Germanicus was given command of the eastern portion of the Empire and Piso was appointed as his legate and made governor of Syria so that he help.[7] This appointment came with the command of 4 legions. Though both he and Germanicus were of the same rank, Germanicus had greater authority (imperium maius). Tacitus suggests that Piso was appointed to act as a check on Germancius, and that he was given secret instructions by Tiberius to thwart and control him.[8]

In the summer of 19, Germanicus had left to take care of matters in Egypt, and when he returned he found that Piso had ignored his orders to the cities and the legions. Germanicus was furious and ordered Piso's recall to Rome.[7] During the feud, Germanicus fell ill and, though Piso had left the province, Germanicus claimed Piso had poisoned him. Piso received a letter from Germanicus renouncing their friendship (amicitia). On 10 October, Germanicus died from the illness. Upon hearing of Germanicus' death, he returned to resume command of Syria.[9]

Trial[edit]

As the death of Germanicus occurred during their feud most people suspected him of having poisoned Germanicus, although this was never proven. The armed attempt by Piso to regain control of Syria immediately after the death of Germanicus only aroused more indignation. This, the rumors of him poisoning Germanicus, and his conduct going back as far as his governorship of Spain were all taken up by the delatores in their accusations against him. It wasn't long before the matter was taken to the Emperor.

Tiberius was forced to order an investigation, and after briefly hearing both sides, decided to defer the case to the senate. Tiberius made no effort to conceal his sentiments: the Pisones were longtime supporters of the Claudians, with their support going back to the early days of Octavian. A public trial was held, and Tiberius made allowances for Piso to summon witnesses of all social orders, including slaves, and he was given more time to plea than the prosecution, but it made no difference: before the sentencing, Piso had died. He committed suicide, though Tacitus supposes that Tiberius may have had him murdered, fearing his own implication in Germanicus' death.[10][11]

The accusations brought against Piso are numerous, including:[12][13]

Although the murder of Germanicus was one of the accusations brought against him, he was only actually found guilty of abandoning and reentering Syria without authorisation to wage war, and for violating Germanicus' imperium, as though they were both of proconsular rank his authority was less than that of Germanicus, who the senate voted to give greater authority (imperium maius) in the eastern provinces before his departure in AD 17.[14][15]

In accordance with the lex Iulia maiestatis, the senate had his property proscribed, forbade mourning on his account, removed images of his likeness, such as statues and portraits, and his name was erased from the base of one statue in particular as part of his damnatio memoriae. Additionally, the senate instructed the curatores locorum publicorum iudicandorum to remove and destroy structures built above Porta Fontinalis to connect his properties. Yet, in a show of clemency not unlike that of the emperor, the senate had Piso's property returned and divided equally between his two sons, on condition that his daughter Calpurnia be given 1,000,000 sesterces as dowry and a further 4,000,000 as personal property. His wife Placina was absolved.[12][16]

His accomplices, a Visellius Karus and a Sempronius Bassus, were to be declared outlaws for committing treason. Their property was to be sold with profits consigned to the aerarium. It is unclear whether or not their case was handled by a judicial authority, such as a quaestio, or by the senate as well.[12][note 1]

Character[edit]

Piso was a man of violent temper, without an idea of obedience, and a natural arrogance. He saw himself as superior to the children of Tiberius.[8] Piso was married to Plancina, a woman of noble rank and wealth. This, combined with Piso's natural character, inflamed his ambition. His sons with Plancina were Gnaeus, who after Piso's death had to take the name of Lucius Calpurnius Piso,[17] and Marcus.

Piso in fiction[edit]

He was played by John Phillips in the ITV series The Caesars and by Stratford Johns in the BBC TV serial I, Claudius.
