Vet. xii. 30-47), supply the loose and scanty materials of this civil war. Ambrose (tom. ii. Epist. xl. p. 952, 953) darkly alludes to the well-known events of a magazine surprised, an action at Petovio, a Sicilian, perhaps a naval, victory, etc. Ausonius (p. 236, edit. Toll.) applauds the peculiar merit and good fortune of Aquileia.
