Gallia
Also called Gallia Transalpina or Gallia Ulterior, to distinguish it from Gallia Cisalpina, or the north of Italy. The Romans commenced the conquest of Gaul B. c. 125, and a few years afterwards made the southeastern part of the country a Roman province. In Caesar's Commentaries the Roman province is called simply Provincia, in contradistinction to the rest of the country; hence comes the modern name of Provence. The rest of the country was subdued by Caesar after a struggle of several years (58-50). At this time Gaul was divided into three parts- Aquitania, Celtica, and Belgica-according to the three different races by which it was inhabited. The Aquitania dwelt in the southwest, between the Pyrenees and the Garumna; the Celtae, or Galli proper, in the center and west between the Garumna and the Sequana and the Matrona; and the Belgae in the northeast, between the two last-mentioned rivers and the Rhine. Of the many tribes inhabiting Gallia Celtica, none were more powerful than the Aedui, the Sequani, and the Helvetii.
Gallienus, Pub. Licinius. A son of the emperor Valerian. He reigned conjointly with his father for seven years, and then became sole emperor, A. D. 260. In his youth he showed military ability in an expedition against the Germans and Sarmatae, but when possessed of the purple he gave himself up to pleasure and vice. He was assassinated in his fiftieth year, A. D. 268.
