Tacitus takes stock of the damage. A good passage to compare this with is Histories 3.72, where Tacitus had described the impact of a later fire on the Capitol, which wrought similar devastation on ancient buildings and heirlooms. (This fire occurred in AD 69 as the result of violence among troops during the chaos surrounding the fall of Vitellius.)
Id facinus post conditam urbem luctuosissimum foedissimumque rei publicae populi Romani accidit, nullo externo hoste, propitiis, si per mores nostros liceret, deis, sedem Iovis Optimi Maximi auspicato a maioribus pignus imperii conditam, quam non Porsenna dedita urbe neque Galli capta temerare potuissent, furore principum excindi. arserat et ante Capitolium civili bello, sed fraude privata: nunc palam obsessum, palam incensum, quibus armorum causis? quo tantae cladis pretio? stetit dum pro patria bellavimus. voverat Tarquinius Priscus rex bello Sabino, ieceratque fundamenta spe magis futurae magnitudinis quam quo modicae adhuc populi Romani res sufficerent. mox Servius Tullius sociorum studio, dein Tarquinius Superbus capta Suessa Pometia hostium spoliis exstruxere. sed gloria operis libertati reservata: pulsis regibus Horatius Pulvillus iterum consul dedicavit ea magnificentia quam immensae postea populi Romani opes ornarent potius quam augerent. isdem rursus vestigiis situm est, postquam interiecto quadringentorum quindecim annorum spatio L. Scipione C. Norbano consulibus flagraverat. curam victor Sulla suscepit, neque tamen dedicavit: hoc solum felicitati eius negatum. Lutatii Catuli nomen inter tanta Caesarum opera usque ad Vitellium mansit. ea tunc aedes cremabatur.
[This was the saddest and most shameful crime that the Roman state had ever suffered since its foundation. Rome had no foreign foe; the gods were ready to be propitious if our character had allowed; and yet the home of Jupiter Optimus Maximus, founded after due auspices by our ancestors as a pledge of empire, which neither Porsenna, when the city gave itself up to him, nor the Gauls when they captured it, could violate – this was the shrine that the mad fury of emperors destroyed! The Capitol had indeed been burned before in civil war, but the crime was that of private individuals. Now it was openly besieged, openly burned – and what were the causes that led to arms? What was the price paid for this great disaster? This temple stood intact so long as we fought for our country. King Tarquinius Priscus had vowed it in the war with the Sabines and had laid its foundations rather to match his hope of future greatness than in accordance with what the fortunes of the Roman people, still moderate, could supply. Later the building was begun by Servius Tullius with the enthusiastic help of Rome’s allies, and afterwards carried on by Tarquinius Superbus with the spoils taken from the enemy at the capture of Suessa Pometia. But the glory of completing the work was reserved for liberty: after the expulsion of the kings, Horatius Pulvillus in his second consulship dedicated it; and its magnificence was such that the enormous wealth of the Roman people acquired thereafter adorned rather than increased its splendour. The temple was built again on the same spot when after an interval of four hundred and fifteen years it had been burned in the consulship of Lucius Scipio and Gaius Norbanus. The victorious Sulla undertook the work, but still he did not dedicate it; that was the only thing that his good fortune was refused. Amid all the great works built by the Caesars the name of Lutatius Catulus kept its place down to Vitellius’ day. This was the temple that then was burned.]
