Publius Ventidius: A Slave Who Was Awarded a Triumph in 38 BC

In 89 BC, a young man entered Rome in chains. He was a captive from Picenum, one of the Italian regions that had rebelled against Rome during the Social War. He was reportedly among the prisoners displayed in the triumph of the Roman commander Gnaeus Pompeius Strabo. Almost fifty years later, the same man entered Rome again, but not as a prisoner. He was a victorious Roman general, returning from the East after defeating the Parthians and killing their king’s son. His name was Publius Ventidius.

Ventidius rose from obscure beginnings to become a senator, praetor, and consul. Then, almost at the end of his career, he became the first Roman general to celebrate a triumph specifically for victory over the Parthians. Ancient writers portrayed him as a lowly muleteer, but surviving evidence suggests something more complicated: he was probably involved in supplying pack animals to Roman armies. Even stripped of the legend, however, his career remains remarkable.

Publius Ventidius – A Captive in a Roman Triumph

Publius Ventidius was born in Picenum, on Italy’s Adriatic coast. The details of his early life are uncertain, but ancient tradition places him among the people captured during the Roman conquest of Asculum in 89 BC. The Roman victory was celebrated by Pompeius Strabo, father of the future Pompey the Great. According to the ancient tradition, Ventidius was young enough to have been among the captives led through Rome during Strabo’s triumph. It is one of the most extraordinary details of his biography, but it should be treated as an ancient account rather than a perfectly documented fact. The sources do not give us a complete biography of Ventidius’ early years.

What happened next is equally difficult to reconstruct. For centuries, Ventidius has been described as having worked as a muleteer after his captivity. That image became central to the story of his rise from poverty to power. But a surviving commentary on Cicero explains that Cicero called Ventidius a muleteer because he had contracted with the Roman authorities to provide the animals needed by an army. The Oxford Classical Dictionary similarly considers him probably an army contractor rather than simply a man driving mules for a living. Still, that was hardly an aristocratic career. But it could put a capable and ambitious man close to the Roman military establishment. And eventually, it brought Ventidius into the orbit of Julius Caesar.

Caesar Opens the Door for Publius Ventidius

Publius Ventidius served with Caesar in Gaul. Whatever his exact origins, he proved useful enough that Caesar helped him enter the Senate in 47 BC. From there, his political career accelerated with astonishing speed, while the Roman Republic was collapsing around him. Caesar had been assassinated in 44 BC. His supporters and enemies were fighting for control, while Octavian, Mark Antony, and Lepidus were moving toward the creation of the Second Triumvirate. Ventidius chose Antony.

In 43 BC, he became praetor. Later that year, when Antony was fighting the forces of the Senate around Mutina, Ventidius marched north with reinforcements. His reward was extraordinary because he was made consul for the final weeks of 43 BC. The captive who had supposedly entered Rome in chains had become one of the Republic’s highest magistrates. But Publius Ventidius wasn’t done.

Rome’s Old Enemy

The Parthians had been a nightmare for Rome ever since the catastrophe of Carrhae in 53 BC. There, the army of Marcus Licinius Crassus had been destroyed, and Crassus himself was killed. Roman standards were captured, thousands of soldiers were killed or enslaved, and the defeat became one of the great humiliations of Roman history. In 40 BC, the Parthians invaded Roman territory again. Their forces entered Syria and Asia Minor, supported by Roman enemies of Antony. Among them was Quintus Labienus, a Roman who had joined the Parthians and helped lead their offensive.

Antony needed someone to stop them. He chose Ventidius. In 39 BC, Ventidius moved rapidly into Asia Minor and confronted Labienus and the Parthian forces supporting him. He defeated them and then pushed against the main Parthian army. At the Amanus Pass, the Romans won another important victory. The Parthian invasion had been stopped. But the following year, the Parthians returned with an even more dangerous commander.

Publius Ventidius Versus Pacorus

In 38 BC, Pacorus, son of the Parthian king Orodes II, entered Syria with a large army. This was no minor raid. Pacorus was the heir to the Parthian throne, and his army threatened to reverse everything Ventidius had achieved.  The armies met at Gindarus in northern Syria, and the result was devastating for the Parthians. Publius Ventidius defeated their army, and Pacorus was killed in the battle. Plutarch describes the victory as one that finally gave the Romans satisfaction for the disaster suffered under Crassus.

The significance went beyond a single battlefield. The Parthian army was driven back, and the threat to Roman Syria was broken. For Rome, the death of Pacorus was especially satisfying because it represented a reversal of the humiliation at Carrhae. For Ventidius, it was the greatest military victory of his life. But then he did something unexpected. 

The General Who Knew When to Stop

According to Plutarch, Ventidius deliberately chose not to pursue the Parthians farther into their territory because he feared provoking Antony’s jealousy. Instead, he turned his attention toward local rulers who had rebelled against Rome. This is Plutarch’s explanation, and we should not automatically treat it as established fact. It does, however, reveal the political danger faced by successful Roman generals in the age of Antony and Octavian. A commander could win too much and become a threat to the man who had given him his command.

Ventidius then besieged Antiochus of Commagene at Samosata. The siege became difficult. Antiochus offered 1,000 talents in exchange for peace and appealed to Antony, who had now arrived in the region. Ventidius refused to settle the matter without his superior’s approval, and Antony took over. According to Plutarch, Antony was determined that at least one success should bear his own name rather than allowing all the glory to go to Ventidius. Yet the siege continued to frustrate him. Eventually, Antony accepted peace for only 300 talents.

The Triumph of Publius Ventidius

On 27 November 38 BC, Publius Ventidius celebrated his triumph, and this is not a later legend. The date and nature of the triumph are recorded in the ancient Fasti Triumphales, which lists Publius Ventidius as a proconsul celebrating victory from Mount Taurus and over the Parthians. It was the first Roman triumph won by a general for victory over the Parthians. And that brings us back to the beginning of his story.

If the ancient tradition is correct, Ventidius had once entered Rome as a captive in someone else’s triumph. Now he entered it as the man whose own victories were being celebrated. The popular phrase that Ventidius was the “only man to enter Rome on both sides of a triumph” is a modern way of expressing this extraordinary contrast, not an ancient title. But it’s true. At least the part that he wasn’t from an aristocratic circle.

The Last Days of Ventidius

After his triumph, Publius Ventidius largely disappears from the historical record. We do not know exactly when he died, but he died not long after his triumph and was honored with a public funeral. His later career is essentially unknown. That silence is almost strange considering what he had accomplished. Ventidius had not conquered Parthia. He had not created a lasting eastern empire for Rome. But that was precisely what Rome needed.

For generations, Parthia had represented one of Rome’s most dangerous enemies. Then came Publius  Ventidius and won. And perhaps the most remarkable part of his story is not that he became a great Roman general. It is that history remembers where he started.
