Lucius Calpurnius Piso the Augur
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, and an augur.
Lucius Calpurnius Piso Caesoninus (consul 15 BC)
Lucius Calpurnius Piso ("PW" 99) (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 brother of Calpurnia, the third and last wife of Julius Caesar.
He was a confidant of the emperors Augustus and Tiberius.
His tenure as pontifex led him sometimes to be called Lucius Calpurnius Piso Pontifex, to differentiate him from his contemporary, Lucius Calpurnius Piso
the Augur, consul in 1 BC.
Piso was consul in 15 BC, and shortly thereafter engaged in Mediolanum as proconsul.
Cassius Dio refers to him as governor of Pamphylia in the years 13 to 11 BC; his province probably included Galatia.
In 11 BC, he was sent to Thrace as legatus "pro praetore" in order to put down a revolt.
For his successes there, the senate honoured him with the ornamenta triumphalia.
Piso may have also been proconsul of Asia and legate of Syria, but this is disputed.
He was "praefectus urbi" from AD 13 to 32, and a trusted adviser to both Augustus and Tiberius.
He was a member of the pontifical college and of the Arval Brethren.
He died in 32, and was honoured with a state funeral.
Piso's achievements and independence were highly regarded.
Horace dedicated his "Ars Poëtica" to him (cf. "
Carmen" 2.12), and several epigrams by Antipater of Thessalonica are dedicated to Piso.
Piso's full nomenclature is somewhat uncertain.
Tacitus simply refers to him as "Lucius Piso", while the "Fasti Albenses" call him "Lucius Calpurnius Piso".
He is sometimes called "Lucius Calpurnius Piso Pontifex", to distinguish him from his contemporary, "Lucius Calpurnius Piso Augur", although both "Pontifex" and "Augur" are simply nicknames, rather than true cognomina.
Drumann assigned Piso the agnomen "Caesoninus", which had been borne by his ancestors for four generations; but in later editions he is assigned the name "Frugi" instead.
There are two grounds for the latter identification.
First, Cassius Dio assigns him the surname "Fourtios", which is supposed to be a corruption of "Frugi".
Secondly, Theodor Mommsen identified his sons, to whom "Ars Poëtica" is addressed, with Lucius Calpurnius Piso and Marcus Licinius Crassus Frugi, consuls in AD 27.
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.
They might instead have been the sons of Gnaeus Calpurnius Piso, consul in 7 BC.
In this instance, Marcus Licinius Crassus Frugi would be identified with the Gnaeus Calpurnius Piso whom the senate compelled to change his praenomen.
As a result, the question of whether Piso the pontifex was surnamed "Caesoninus" or "Frugi" is unresolved.
Porcia (wife of Brutus)
Porcia Catonis (c. 70 BC – June 43 BC (or October 42 BC)), (Porcia "of Cato", in full "Porcia Catonis filiaPorcia the daughter of Cato") also known simply as Porcia, occasionally spelled "Portia", especially in 18th-century English literature, was a Roman woman who lived in the 1st century BC.
She was the daughter of Marcus Porcius Cato Uticensis and his first wife Atilia.
She is best known for being the second wife of Marcus Junius Brutus, the most famous of Julius Caesar's assassins, and for her suicide, reputedly by swallowing hot coals.
Lucius Calpurnius Bibulus
Lucius Calpurnius Bibulus (? – died around 32 B.C.) was a Roman statesman.
Lucius Bibulus was the son of Julius Caesar's implacable enemy Marcus Calpurnius Bibulus and possibly, Porcia Catonis (daughter of Cato the Younger), although it is unlikely.
His two elder brothers were killed in Egypt by some of the soldiery which Aulus Gabinius had left there after having restored Ptolemy Auletes to the throne.
His father died in 48 BC from the exhaustion and strain of commanding the republican fleets against Caesar.
After Caesar's murder, Lucius chose the side of Marcus Junius Brutus, Porcia's new husband, for whom he fought at the battle of Philippi.
After the defeat of Caesar's murderers, he surrendered to Marcus Antonius who later gave him command of his fleet.
Bibulus was later made governor of Syria by Augustus and he died around 32 BC.
Lucius Calpurnius Piso Caesoninus (consul 112 BC)
Lucius Calpurnius Piso Caesoninus was the son of Lucius Calpurnius Piso Caesoninus, consul in 148 BC.
He was consul in 112 BC, with Marcus Livius Drusus.
In 107 BC, he served as legate to the consul, Lucius Cassius Longinus, who was sent into Gaul to oppose the Cimbri and their allies, and he fell together with the consul in the battle, in which the Roman army was utterly defeated by the Tigurini in the territory of the Allobroges.
