Gaius Petronius was a Roman senator, who was active during the Principate. He was suffect consul from September through December AD 25, succeeding Cossus Cornelius Lentulus. [1] Bartolomeo Borghesi has argued that Gaius Petronius is the same person as Gaius Petronius Umbrinus, who is mentioned in an inscription from Rome as curator locorum publicorum iudicandorum. [2]
Petronius was grandson of Publius Petronius Turpilianus, one of the tresviri monetalis , and probably grandson of Publius Petronius, prefect of Egypt. Publius Petronius, suffect consul in 19, was probably his older brother. [3]
