The wealth of Italy supplied the expenses of the war; and the adjacent provinces were exhausted, to form immense magazines of corn and every other kind of provisions. The whole force of Constantine consisted of ninety thousand foot and eight thousand horse; and as the defence of the Rhine required an extraordinary attention during the absence of the emperor, it was not in his power to employ above half his troops in the Italian expedition, unless he sacrificed the public safety to his private quarrel.
