SALVS PROVINCIARVM.----The Rhine personified, under the recumbent figure of a bearded man, having two horns on his forehead (Rhenus bicornis), his right hand placed on a prow, his left holding a reed, and resting on an urn.----On gold and silver of Postumus----a type of elegant design for the age in which it was struck.----Having in the strongest manner fortified the Rhine on both its banks with camps and citadels, Postumus watched over the welfare (salus) of the Gallic provinces. It is thus that Trebellius speaks of him: Si quidem nimius amor erga Postumum omnium erat in Gallica gente populorum, quod submotis omnibus Germanicis gentibus, Romanum in pristinam securitatem revocasset imperium.
The title bestowed in the above legend on the Rhine, as being the health or safety of the Provinces, was doubtless appropriate to that mighty stream, which either hindered altogether, or rendered extremely difficult, the incursions of barbarians into a most important portion of the Roman empire. The river god is represented furnished with two horns, exactly according to Virgil, Rhenusque bicornis----an epithet which is repeated also by Ausonius; and Eumenius likewise calls the Rhine bicornis. The attribute of horns, which the ancients usually assigned to rivers, is in this case with more than ordinary suitableness applied, because the Rhine emptied itself into the sea by two horns, or channels. Hence the above-named Eumenius observes:----alvei unius impatiens in sua cornua gestit excedere.----Paneg. Cons. Aug. vii. 13. (Dictionary of roman coins)
