This legend and type appear on a brass medallion, struck in honor of the Emperors Trebonianus Gallus, and Volusianus, jointly, about A.D. 252, the computed year of their arrival in Rome, after the death of Trajanus Decius, whose son Hostilianus had already been associated with Trebonianus as an Augustus.

On the obverse are the laurelled heads of both father and son, surrounded by the legend IMP GALLVS AVG IMP VOLVSIANVS AVG.--The above cut is copied from the volume of Buonarotti (pl. xviii.),, who praises this medallion as equal, in point both of design and workmanship, to the best examples of die-engraving, to be found in the mints of the earlier empire. Thus much for art and taste, as still occasionally found manifested even in the lower age of the imperial coinage. But the device of two equestrian warriors, one with couched lance, as if preparing t charge an enemy, is a more appropriate type for a decursio or a profectio militaris, than for the peaceful approach of two newly-elected Emperors to the gates of "the eternal city." There is, moreover, something more than strange in the assumption of the imperial title by both Gallus and Volusianus--a cirucmstance which, as the learned and acute author of "Osservazione Istoriche" remarks (p. 312)--"fa molto sospettare che Ostiliano, non vedendosi nominato, fosse gia morto, o di peste, o di morte violenta, procuratagli da Gallo, per gelosia d 'Imperio." The suspicion of foul play, in this case, is of the two, by far the more probably hypothese.

ADVENTVS AVGG.--There is a silver medallion, edited by Buonarotti, bearing on its obverse the head of Saloninus Valerianus Caesar, without laurel crown, on the one side, and face to face, with that of Gallienus, his father, laureated, on the other side--the legend being CONCORDIA AVGVSTORVM.--The reverse exhibits three galeated figures on horseback, their right hands raised. Victory preceding them, and fice soldiers accompanying them, three of who bear military ensigns. Near the horses ' feet are two captives seated on the ground. See CONCORDIA AVGVSTORVM.
