78 (return) [ The younger Victor assigns to his exile the emphatical appellation of “Voluptarium otium.” Socrates (l. ii. c. 28) is the voucher for the correspondence with the emperor, which would seem to prove that Vetranio was indeed, prope ad stultitiam simplicissimus.] The behavior of Constantius on this memorable occasion was celebrated with some appearance of justice; and his courtiers compared the studied orations which a Pericles or a Demosthenes addressed to the populace of Athens, with the victorious eloquence which had persuaded an armed multitude to desert and depose the object of their partial choice. 79 The approaching contest with Magnentius was of a more serious and bloody kind. The tyrant advanced by rapid marches to encounter Constantius, at the head of a numerous army, composed of Gauls and Spaniards, of Franks and Saxons; of those provincials who supplied the strength of the legions, and of those barbarians who were dreaded as the most formidable enemies of the republic. The fertile plains 80 of the Lower Pannonia, between the Drave, the Save, and the Danube, presented a spacious theatre; and the operations of the civil war were protracted during the summer months by the skill or timidity of the combatants. 81 Constantius had declared his intention of deciding the quarrel in the fields of Cibalis, a name that would animate his troops by the remembrance of the victory, which, on the same auspicious ground, had been obtained by the arms of his father Constantine. Yet by the impregnable fortifications with which the emperor encompassed his camp, he appeared to decline, rather than to invite, a general engagement.
