354 CE
As a result of the armies of the West having been largely withdrawn by the usurper Magnus Magnentius, to fight Constantius II, hordes of barbarians (Franks and Alemanni) cross the upper Rhine into Gaul and invade the lands of the Helvetians. Emperor Constantius II recalls his Caesar (and cousin) Constantius Gallus to Constantinople after hearing unfavorable reports about him. Gallus, Caesar of the East, has suppressed revolts in Syria Palaestina and central Anatolia. Constantius strips him of his powers and later has him executed in Pola (Croatia). Libanius becomes a teacher of rhetoric in Antioch; his students include John Chrysostom and Theodore of Mopsuestia.
