Valerius Maximus, Memorable Deeds and Sayings 1.1.20
Q. autem Fulvius Flaccus inpune non tulit, quod in censura tegulas marmoreas ex Iunonis Laciniae templo in aedem Fortunae equestris, quam Romae faciebat, transtulit; negatur enim post hoc factum mente constitisse. quin etiam per summam aegritudinem animi expiravit, cum ex duobus filiis in Illyrico militantibus alterum decessisse, alterum graviter audisset adfectum. cuius casu motus senatus tegulas Locros reportandas curavit decretique circumspectissima sanctitate inpium opus censoris retexuit.
Quintus Fulvius Flaccus did not escape unpunished when, during his censorship, he transferred the marble tiles from the temple of Juno Lacinia to a temple of Equestrian Fortune which he was constructing in Rome – certainly it is said that after this deed he was never again in his right mind. And, to be sure, he did die amid the greatest mental sickness, after hearing that one of his two sons had died fighting in Illyricum, and the other had been seriously wounded. The senate, which was distressed at his misfortune, ensured that the tiles were brought back to Locri; by the most well-considered holiness of its decree, the senate undid the censor’s impious deed.
