Gaius Julius Plancius Varus Cornutus was a man of Roman Senatorial rank who lived in the Roman Empire in the 2nd century.
Cornutus was the son and only child of Gaius Julius Cornutus Tertullus the Younger and Plancia Magna. His paternal grandparents were the Proconsul and Suffect Consul Gaius Julius Cornutus Tertullus and possibly Tertulla. While his maternal grandparents were the Roman Senator and Proconsul Marcus Plancius Varus and Herodian Princess Julia. His family were prominent citizens and patrons in Perga.
Cornutus was of Roman, Jewish, Nabataean, Edomite, Greek, Armenian and Persian ancestry. Through his maternal grandmother, Cornutus' ancestors were King Archelaus of Cappadocia, King of Judea Herod the Great and his wife Mariamne. Cornutus along with his mother, maternal uncle Gaius Plancius Varus and his maternal relatives were among the last known descendants of the Herodian Dynasty. He appeared to be an apostate to Judaism. It is unlikely that Cornutus attempted to exert influence on Judean Politics. He was born and raised in Perga, the capital of the Roman province of Pamphylia.
