Bonum principem Carum fuisse cum multa indicant tum illud etiam, quod statim ut est adeptus imperium, Sarmatas adeo morte Probi feroces ut invasuros se non solum Illyricum sed Thracias quoque Italiamque minarentur, ita scienter bella partiendo contudit, ut paucissimis diebus Pannonias securitate donaverit occisis Sarmatarum sedecim milibus, captis diversi sexus viginti milibus.
Translation :
That Carus was a good emperor is evident from many of his deeds but especially from this, that as soon as he received the imperial power he crushed the Sarmatians, who were so emboldened by Probus' death that they threatened to invade not only Illyricum but Thrace and Italy as well, and he showed such skill in breaking up the war that in a very few days he made the provinces of Pannonia free from all fear, having killed sixteen thousand Sarmatians and captured twenty thousand of both sexes.
