Editing Constantius Gallus (section)

==Fall and death ==
Constantius was informed of the treason trials in Antioch during a campaign against the [[Alamanni]]. After concluding a peace treaty with the Germanic tribe, Constantius decided to settle the matter with his cousin. First he summoned Ursicinus to the West, whom he suspected of inciting Gallus in order to create the occasion for a revolt and the usurpation of his own son.{{sfn|Crawford|2016|p=98}}

Next, Constantius summoned Gallus and Constantina to [[Mediolanum]]. Constantina left first, in order to gain some of her brother's trust, but suddenly died from a fever at Caeni Gallicani in [[Bithynia]].{{sfn|Crawford|2016|p=98}} Gallus, whose bonds to Constantius had been weakened, stayed in Antioch. Constantius tried to lure Gallus, sending the ''tribunus scutariorum'' [[Scudilo]] to tell Gallus that Constantius wanted to raise him to ''[[Augustus (title)|Augustus]]''. Gallus took Constantius's bait and left Antioch to meet him. Gallus staged a chariot race in Constantinople's ''[[Hippodrome of Constantinople|Hippodrome]]'' and crowned the victor, an honor reserved only for an Augustus. This insolence enraged Constantius. In an attempt to further isolate Gallus from any form of military protection, Constantius had the garrisons removed from the towns in Gallus's path.{{sfn|Crawford|2016|p=99}}

When Gallus arrived at [[Poetovio]] in [[Noricum]], [[Barbatio]], an officer who had been supporting Gallus' dismissal within Constantius' court, surrounded the palace of the Caesar and arrested him, stripping Gallus of the imperial robes, but assuring him that no harm would come to him. Gallus was led to [[Pula|Pola]], Istria (now Pula, Croatia). Here he was interrogated by some of the highest officials of Constantius' court, including the eunuch ''[[praepositus sacri cubiculi]]'' [[Eusebius (praepositus sacri cubiculi)|Eusebius]] and the ''[[agens in rebus]]'' [[Apodemius]]. Gallus tried to put the blame for all of his actions on Constantina, but Constantius sentenced him to death; the emperor later changed his mind, and ordered Gallus spared, but Eusebius prevented the order from reaching the executioners.
