When Gauls under the command of Brennus attempted to scale the Capitoline, Manlius was roused by the cackling of the sacred geese, rushed to the spot, and threw down the foremost assailants.
He was charged with aspiring to kingly power, and condemned by the comitia, but not until the assembly had adjourned to a place outside the walls, where they could no longer see the Capitol which he had saved.
[4] Some scholars suggest that Livy's portrait of Manlius is modeled on the first-century rebel Catiline, and blends different moments in Rome's recent past.
[5] Manlius' house on the Capitoline Hill was razed, and the Senate decreed that no patrician should live there henceforth.
He saved the life of P. Servilius, the master of the horse, receiving wounds on the same occasion in the shoulders and the thigh.
