There were two Romans of Senatorial rank with the name Gaius Julius Cornutus Tertullus who lived in the 1st and 2nd centuries in the Roman Empire. One was a father, the other his son.
Gaius Julius Cornutus Tertullus was the son of a prominent citizen from Perga, Gaius Julius Cornutus Bryonianus and there is a possibility that his mother’s name could have been Tertulla. He was born and raised in Attaleia (modern Antalya) in the Roman province of Pamphylia.
Tertullus served as a Roman Governor of Crete and Cyrene. After 70 the Roman Emperor Vespasian promoted him to Praetorian Rank. In the reign of Vespasian’s second son Domitian (81-96), Tertullus served as a Proconsul of Gallia Narbonensis.
In 98, Tertullus was appointed Prefect of the Treasury. His colleague in his appointment was his friend the historian and Roman Senator Pliny the Younger. In 100 Tertullus served as a suffect consul, while Pliny served as a consul in Rome.
Between 109-110, Tertullus conducted a census in Gallia Aquitania and between 112-115 served as a Proconsul of Bithynia and Pontus. Then again Tertullus served as a Proconsul of the Africa Province between 116-118. Tertullus married an unnamed Roman woman from this marriage had a son of the same name (see below) and a daughter called Julia Tertulla.
Gaius Julius Cornutus Tertullus was the son to the above and the identity of his mother is unknown. He was born and raised in Perga, the capital of the Roman province of Pamphylia. Unfortunately very little is known on him.
This Tertullus married a Roman woman from Perga called Plancia Magna, who a prominent citizen and patron of Perga. Magna was the daughter of Roman Senator and Proconsul Marcus Plancius Varus and Herodian Princess Julia. Tertullus and Magna had a son and only child called Gaius Julius Plancius Varus Cornutus.
