Trebonianus Gallus
Trebonianus Gallus
(Latin: Gaius Vibius Afinius Trebonianus Gallus Augustus;[1][2] 206 – August 253), also known as Gallus, was Roman Emperor from 251 to 253, in a joint rule with his son Volusianus.

Early life[edit] Gallus was born in Italy, in a family with respected ancestry of Etruscan senatorial background. He had two children in his marriage with Afinia Gemina Baebiana: Gaius Vibius Volusianus, later Emperor, and a daughter, Vibia Galla. His early career was a typical cursus honorum, with several appointments, both political and military. He was suffect consul and in 250 was nominated governor of the Roman province of Moesia
Superior, an appointment that showed the confidence of Emperor Trajan
in him. Rise to power[edit] In June 251, Decius
and his co-emperor and son Herennius Etruscus

they were supposed to punish for raids into the empire. According to rumours supported by Dexippus (a contemporary Greek historian) and the Thirteenth Sibylline Oracle, Decius' failure was largely owing to Gallus, who had conspired with the invaders. In any case, when the army heard the news, the soldiers proclaimed Gallus emperor, despite Hostilian, Decius' surviving son, ascending the imperial throne in Rome. This action of the army, and the fact that Gallus seems to have been on good terms with Decius' family, makes Dexippus' allegation improbable.[3] Gallus did not back down from his intention to become emperor, but accepted Hostilian
as co-emperor, perhaps to avoid the damage of another civil war.

Anxious to secure his position at Rome and stabilize the situation on the Danube frontier, Gallus made peace with the Goths. Peace terms allowed the Goths
to leave the Roman territory while keeping their captives and plunder. In addition, it was agreed that they would be paid an annual subsidy.[5] Reaching Rome, Gallus' proclamation was formally confirmed by the Senate, with his son Volusianus
being appointed Caesar. On June 24, 251, Decius
was deified, but by July 15 Hostilian
disappears from history—he may have died in an outbreak of plague.[6] Gallus may have also ordered a localized and uncoordinated persecution of Christians.[7] However, only two incidents are known to us: the exile of Pope Cornelius

to Centumcellae, where he died in 253 and the exile of his successor, Pope Lucius, right after his election. The latter was recalled to Rome during the reign of Valerian.[8]

Radiate of Trebonianus Gallus

Like his predecessors, Gallus did not have an easy reign. In the East, an Antiochene nobleman, Mariades, revolted and began ravaging Syria and Cappadocia, then fled to the Persians. Gallus ordered his troops to attack the Persians, but Persian Emperor Shapur I
Shapur I
invaded Armenia and destroyed a large Roman army, taking it by surprise at Barbalissos in 253. Shapur I

then invaded the defenseless Syrian provinces, captured all of its legionary posts and ravaged its cities, including Antioch, without any response.[9] Persian invasions were repeated in the following year, but now Uranius
Antoninus (a priest originally called Sampsiceramus), a descendant of the royal house of Emesa, confronted Shapur and forced him to retreat. He proclaimed himself emperor,[7] however, and minted coins with his image upon them.[10] On the Danube, Scythian
tribes were once again on the loose, despite the peace treaty signed in 251. They invaded Asia Minor by sea, burned the great Temple of Artemis

at Ephesus, and returned home with plunder. Lower Moesia
was also invaded in early 253.[11] Aemilianus, governor of Moesia
Superior and Pannonia, took the initiative of battle and defeated the invaders. Death[edit]

Trebonianus Gallus

Since the army was no longer pleased with the Emperor, the soldiers proclaimed Aemilianus
emperor. With a usurper, supported by Pauloctus, threatening the throne, Gallus prepared for a fight. He recalled several legions and ordered reinforcements to return to Rome from Gaul under the command of the future emperor Publius Licinius
Valerianus. Despite these dispositions, Aemilianus
marched onto Italy
ready to fight for his claim and caught Gallus at Interamna (modern Terni) before the arrival of Valerianus. What exactly happened there is not clear.[12] Later sources claim that after an initial defeat, Gallus and Volusianus
were murdered by their own troops;[11] or Gallus did not have the chance to face Aemilianus
at all because his army went over to the usurper.[13] In any case, both Gallus and Volusianus
were killed in August 253.[14] Notes[edit]
