Gaius Antistius Vetus (consul 30 BC)

Gaius Antistius Vetus was a Roman senator who served as consul in 30 BC alongside Octavian, later the Emperor Augustus. He belonged to the gens Antistia, a plebeian family.

Details about Antistius Vetus' early life and career prior to his consulship are largely unknown. His election as consul in 30 BC is significant, as it occurred during the turbulent period following the assassination of Julius Caesar and the subsequent power struggles between Octavian, Mark Antony, and others. Octavian's choice of Antistius Vetus as his colleague likely indicates a degree of political alignment or at least the absence of active opposition.

While the consulship of 30 BC was dominated by Octavian's preparations for and subsequent campaign against Mark Antony and Cleopatra in Egypt, Antistius Vetus would have shared in the responsibilities of managing the day-to-day affairs of Rome. However, the details of his specific contributions are scarce.

Following his consulship, little is definitively known about Antistius Vetus' later life. He likely continued to serve in the Senate and hold other public offices, but specific records are lacking.
