on the Rhine frontier. In 355 the Franks had destroyed Cologne (Agrippina), making it a desert of ruins, and the Alamanni had occupied the countryside of Alsace, isolating but not occupying the cities there. A list is given (in the accusative case), presumably including the "alia municipia" of "Prima Germania": Argentoratum (Strasbourg), Brotomagum (Brumath), Tabernas (Saverne), Salisonem (Selz), Nemetas (Speyer), Vangionas (Worms) and Mogontiacum (Mainz). In 356 Julian moved to the relief of the cities, driving out the Alamanni, and reoccupied Cologne, forcing the Franks to the peace table. He went into winter quarters at Sens and was besieged there by the Alamanni but they became discouraged and departed before the campaign season began. Notitia Dignitatum The 5th century Notitia Dignitatum records eleven prefectures in the domain (sub dispositione...) of the "Duke of Mainz" (Dux Mogontiacensis). Ruling over one of them from the castellum Vangionis (locative case of either Vangionis or Vangio) is the Praefectus militum Secundae Flaviae, Vangiones; that is, the prefect of a district called Secunda Flavia among the Vangiones. This domain includes 11 prefectures in the Rhineland and northern Alsace.
