Aurelius Victor, de Caesaribus 2:
Claudius Tiberius, son of Livia, stepson of Octavian, ruled for twenty three years. Because he was called Claudius Tiberius Nero, the more jocular citizens wittily called him Caldius Biberius Mero (Warmius Drinkius Wino) because of his tippling tendencies. He was smart enough in battle, and fortunate enough before power was taken up under Augustus, so that the dominion over the republic was not undeservedly committed to him.
There was in him ample literary knowledge. He was fairly renowned for his speech, but had the worst mind – truculent, greedy, treacherous – pretending that he wanted things that he didn’t. He appeared to be opposed to those from whom he wanted counsel, and seemed totally benevolent to those whom he hated. He was better in his immediate responses and plans than in those which had been thought out.
When the principate was offered to him by the senators (which he had brought about with some cunning), he pretended to decline it, savagely asking each one individually what they had to say or what they thought about it. This ruined some good men. For they supposed that it was from his own mind that he declined the magnitude of imperial bother with a long speech, and when they offered opinions on this wish, they happened ultimately upon destruction.
He returned Cappadocia to the condition of a province by removing their king, Archelaus. He repressed the robberies of the Gaetuli. He cunningly circumvented Marobodus, the king of the Suebi. While he punished alike with savage fury both innocent and guilty, his own people and others, the strength of the military was sapped and Armenia was taken by the Parthians, Moesia by the Dacians, Pannonia by the Sarmatians, and Gaul by neighboring tribes. He himself was snuffed out by the treachery of Caligula in the fourth month of his eighty eighth year.
Claudius Tiberius, Liviae filius, Caesaris Octaviani privignus, imperavit annos viginti tres. Iste, quia Claudius Tiberius Nero dicebatur, eleganter a iocularibus Caldius Biberius Mero ob vinolentiam nominatus est. Satis prudens in armis satisque fortunatus ante sumptum imperium sub Augusto fuit, ut non immerito reipublicae dominatus ei committeretur. Inerat ei scientia litterarum multa. Eloquio clarior, sed ingenio pessimo truci avaro insidioso, simulans ea se velle quae nollet; his quasi infensus, quibus consultum cupiebat, his vero, quos oderat, quasi benivolus apparens. Repentinis responsionibus aut consiliis melior quam meditatis. Denique delatum a patribus principatum (quod quidem astu fecerat) ficte abnuere, quid singuli dicerent vel sentirent, atrociter explorans: quae res bonos quosque pessumdedit. Aestimantes enim ex animo eum longa oratione imperialis molestiae magnitudinem declinare, cum sententias ad eius voluntatem promunt, incidere exitia postrema. Iste Cappadocas in provinciam remoto Archelao rege eorum redegit. Gaetulorum latrocinia repressit. Marobodum, Suevorum regem, callide circumvenit. Cum immani furore insontes noxios, suos pariter externosque puniret, resolutis militiae artibus Armenia per Parthos, Moesia a Dacis, Pannonia a Sarmatis, Gallia a finitimis gentibus direptae suntIpse post octogesimum octavum annum et mensem quartum insidiis Caligulae exstinctus est.
