Background
Quietus was the son of Fulvius Macrianus and a noblewoman, possibly named Iunia.
Quietus was the son of Fulvius Macrianus and a noblewoman, possibly named Iunia.
According to Historia Augusta, he was a military tribune under Valerian, but this information is challenged by historians. With the lawful heir, Gallienus, being far away in the West, the soldiers elected the two emperors. The support of his father, controller of the imperial treasure, and the influence of Balista, Praetorian prefect of the late Emperor Valerian, proved instrumental in his promotion.
Quietus and Macrianus, elected consuls, had to face the Emperor Gallienus, at the time in the West.
Forced to flee to the city of Emesa, he was besieged there by Odaenathus, during the course of which he was killed by its inhabitants, possibly instigated by Ballista. Quietus appears in Harry Sidebottoms historical fiction novel series as one of the series antagonists.
