Traduction revers: “Libertas Augusti”, (La Liberté de l’auguste). Historique: Claude II fut nommé maître de la Cavalerie après la défection d'Auréolus et fit partie du complot qui élimina Gallien. Ayant promis la vie sauve à Auréolus après la mort de Gallien, il le laissa néanmoins massacrer par ses troupes après la reddition de Milan. Claude II remporta une brillante victoire sur les Goths à Naissus en Mésie supérieure. Malheureusement, les vaincus propagèrent la peste parmi les vainqueurs et Claude en fut victime. Il fut divinisé après sa mort et un important monnayage de restitution fut frappé par Aurélien d'abord en 270, puis par Constantin Ier qui prétendait descendre de Claude II, au début du IVe siècle.

8. ebay Claudius II - Roman Emperor: 268-270 A.D. Bronze Antoninianus 19mm (2.83 grams) Struck circa 268-270 A.D. Reference: RIC 63f, C 152 IMPCLAVDIVSAVG - Radiate, cuirassed bust right. LIBERTAVG Exe: Nothing or X - Libertas standing, facing, holding pileus and scepter. The pileus (from Greek πῖλος - pilos, also pilleus or pilleum in Latin) was a brimless, felt cap worn by sailors in Ancient Greece and later copied by Ancient Rome. It became emblematic of liberty and freedom from bondage. During the classic revival of the 18th and 19th centuries it was widely confused with the Phrygian cap which, in turn, appeared frequently on statuary and heraldic devices as a "liberty cap." LIBERTAS - Liberty is represented in two ways on coins: the one as a woman with a naked head, which is the image of Roman Liberty; the other having her head covered with a veil, and adorned with a diadem, is the effigy of the goddess of liberty, whose temple was on Mount Aventine. The veil is in this case the token of divinity, as indeed the diadem is the ornament of a goddess. Liberty is represented not only on consular medals, but also with considerable frequency on those of the imperial series. Marcus Aurelius Claudius (May 10, 213 - January, 270), often referred to as Claudius Gothicus or Claudius II, was a Roman Emperor. He ruled the Roman Empire for less than two years (268 - 270), but during that brief time he managed to obtain some successes. He was later given divine status. Life Origin and rise to power Claudius' origin is uncertain. He was either from Sirmium (Syrmia; in Pannonia Inferior) or from Naissus Dardania (in Moesia Superior); both areas are located in Serbia. Claudius was the commander of the Roman army that decisively defeated the Goths at the Battle of Naissus in September 268; in the same month, he attained the throne, amid charges, never proven, that he murdered his predecessor Gallienus. However, he soon proved to be less than bloodthirsty, as he asked the Roman Senate to spare the lives of Gallienus' family and supporters. He was less magnanimous toward Rome's enemies, however, and it was to this that he owed his popularity. Claudius, like Maximinus Thrax before him, was of barbarian birth. After an interlude of failed aristocratic Roman emperors since Maximinus's death, Claudius was the first in a series of tough soldier-emperors who would eventually restore the Empire from the Crisis of the third century. Claudius as emperor. At the time of his accession, the Roman Empire was in serious danger from several incursions, both within and outside its borders. The most pressing of these was an invasion of Illyricum and Pannonia by the Goths. Not long after being named emperor (or just prior to Gallienus' death, depending on the source), he won his greatest victory, and one of the greatest in the history of Roman arms. The Roman Empire in 268 A.D. At the Battle of Naissus, Claudius and his legions routed a huge Gothic army. Together with his cavalry commander, the future Emperor Aurelian, the Romans took thousands of prisoners, destroyed the Gothic cavalry as a force and stormed their laager (a circular alignment of wagons long favored by the Goths). The victory earned Claudius his surname of "Gothicus" (conqueror of the Goths), and that is how he is known to this day. More importantly, the Goths were soon driven back across the Danube River, and a century passed before they again posed a serious threat to the empire. While this was going on, the Germanic tribe known as the Alamanni had crossed the Alps and attacked the empire. Claudius responded quickly, routing the Alamanni at the Battle of Lake Benacus in the late fall of 268, a few months after the battle of Naissus. He then turned on the Gallic Empire, ruled by a pretender for the past fifteen years and encompassing Britain, Gaul, and the Iberian Peninsula. He won several victories and soon regained control of Spain and the Rhone river valley of Gaul. This set the stage for the ultimate destruction of the Gallic Empire under Aurelian. However, Claudius did not live long enough to fulfill his goal of reuniting all the lost territories of the empire. Late in 269 he was preparing to go to war against the Vandals, who were raiding in Pannonia. However, he fell victim to the Plague of Cyprian (possibly smallpox), and died early in January 270. Before his death, he is thought to have named Aurelian as his successor, although Claudius' brother Quintillus briefly seized power. The Senate immediately deified Claudius as "Divus Claudius Gothicus". Links to Constantinian dynasty. The Historia Augusta reports Claudius and Quintillus having another brother named Crispus and through him a niece. Said niece Claudia reportedly married Eutropius and was mother to Constantius Chlorus. Historians however suspect this account to be a genealogical fabrication intended to link Constantine I's family to that of a well-respected emperor.
