261 CE
Odaenathus had taken the side of Gallienus, the son and successor of Valerian, after the two usurping emperors had been proclaimed in the East.
The usurper Quietus, after the defeat of his brother and father in Thrace in 261, flees to the city of Emesa (now Homs, Syria), where he is besieged by Odaenathus, during the course of which he was killed by its inhabitants, possibly instigated by Ballista.
